Resumo A ideia do tema surgiu da fala racional da aluna,primeira autora sobre homeopatia e o questionamento sobre ciência e pseudociência. No processo de construção da química como ciência a alquimia deixou contribuições importantes como técnicas de laboratório e a figura de Paracelsus que organizou as primeiras comunidades científicas. A ciência é uma construção humana e essa construção se deu por um processo influenciado por diferentes fatores.O conhecimento científico é resultado de processos que seguem formalidades e surge do rigor do que é chamado método científico. A metodologia de trabalho foi a aplicação de um questionário do tipo formulário eletrônico que teve o cuidado de ser direcionado a pessoas que tivessem ligação com a ciência em seu cotidiano profissional,para esta etapa específica foi feito um recorte nas respostas dos participantes e selecionados somentes docentes do IQ da UnB.Os resultados foram analisados utilizando um método quali-quantitativo. Quando o formulário foi interrrompido para respostas contava com 61 participações e deste total 16 docentes. Foi verificado que os participantes estão divididos na crença sobre a homeopatia e a ciência, contudo o interessante é que mesmo dois participantes que nao acreditam recorrem a homepatia para tratar sintomas que tratam também com medicamentos alopáticos. Em tempos pós pandemia é importante que se volte o olhar para a ciência e de crédito ao papel do cientista no enfretamento das questões. Contudo a homepatia não pode ser desconsiderada como uma prática de cuidado pois faz parte de um rol de linhas terapeuticas do SUS que tem um olhar para o indivíduo e sua integralidade e não desconsideram a alopatia.

Abstract The idea for the theme came from the student's rational speech, the first author on homeopathy and the questioning of science and pseudoscience. In the process of building chemistry as a science, alchemy left important contributions such as laboratory techniques and the figure of Paracelsus who organized the first scientific communities. Science is a human construction and this construction took place through a process influenced by different factors. Scientific knowledge is the result of processes that follow formalities and arises from the rigor of what is called the scientific method. The work methodology was the application of an electronic form-type questionnaire that was careful to be directed to people who had a connection with science in their professional routine. UnB IQ. The results were analyzed using a quali-quantitative method. When the form was interrupted for responses, there were 61 participants and of this total, 16 teachers. It was verified that the participants are divided in their beliefs about homeopathy and science, however, the interesting thing is that even two participants who do not believe resort to homeopathy to treat symptoms that they also treat with allopathic medicines. In post-pandemic times, it is important to look at science and credit the scientist's role in dealing with these issues. However, homeopathy cannot be disregarded as a care practice, as it is part of a list of therapeutic lines of the SUS that look at the individual and his integrality and do not disregard allopathy.

Resumo As samambaias são frequentemente usadas pelos indígenas em Khyber Pakhtunkhwa, Paquistão. Este estudo foi desenhado para coletar o conhecimento etnomedicinal e tradicional desses moradores sobre este grupo de plantas vasculares. Quarenta táxons pertencem a dezenove gêneros, e dez famílias são utilizadas no tratamento de diferentes doenças. Pteridaceae foi a família mais representativa com doze táxons (30%), seguida por Athyriaceae e Dryopteridaceae com seis táxons cada (30%), e Thelypteridaceae com cinco táxons (12,5%). Em relação aos gêneros, Adiantum, Asplenium e Dryopteris ficaram em primeiro lugar com quatro táxons cada (30%), seguidos por Aleuritopteris, Diplazium, Pteris e Equisetum com três táxons cada (30%), e Athyrium, Oeosporangium, Polystichum e Pseudophegopteris com dois táxons cada (20%). Estes táxons foram comumente usados no tratamento de distúrbios respiratórios, isto é, asma, bronquite, enfisema, pneumonia; úlcera intestinal, estômago, doenças urinárias e doenças da pele pelos métodos de decocção e infusão. O conhecimento tradicional sobre plantas etnomedicinais é uma fonte valiosa e essencial para a descoberta de medicamentos alopáticos, fitoterápicos e homeopáticos.

Abstract Ferns are often used by indigenous people in Khyber Pakhtunkhwa, Pakistan. This study was designed to collect the ethnomedicinal and traditional knowledge of these locals about this group of vascular plants. Forty taxa belong to nineteen genera and ten families are used in the treatment of different diseases. The Pteridaceae was the most representative family with twelve taxa (30%), followed by Athyriaceae and Dryopteridaceae with six taxa each (30%), and Thelypteridaceae with five taxa (12.5%). Regarding the genera, Adiantum, Asplenium and Dryopteris ranked first with four taxa each (30%), followed by Aleuritopteris, Diplazium, Pteris and Equisetum with three taxa each (30%), followed by Athyrium, Oeosporangium, Polystichum and Pseudophegopteris with two taxa each (20%). These taxa were commonly used in the treatment of respiratory disorders i.e. asthma, bronchitis, emphysema, pneumonia; intestinal ulcer, stomach, urinary ailments and skin disorders by the methods of decoction and infusion. Traditional knowledge about ethnomedicinal plants is a valuable and essential source for the discovery of allopathic, herbal and homeopathic medicines.

RESUMEN Objetivo. Identificar y analizar los incidentes de productos médicos subestándares, falsificados, no registrados y robados al inicio de la pandemia de COVID-19. Métodos. Búsqueda detallada en los sitios web de las autoridades reguladoras de las Américas. Identificación de los incidentes de medicamentos y dispositivos médicos (incluidos los de diagnóstico in vitro) subestándares falsificados, no registrados y robados. Se determinaron los tipos de productos, las etapas de la cadena de suministro en las que se detectaron y las medidas tomadas por las autoridades. Resultados. Se identificaron 1 273 incidentes en 15 países (1 087 productos subestándares, 44 falsificados, 123 no registrados y 19 robados). La mayor cantidad de incidentes corresponden a dispositivos médicos, desinfectantes y antisépticos. El punto en la cadena de suministro con mayor frecuencia de informes fue la adquisición a través de internet. Las medidas tomadas por las autoridades reguladoras corresponden en su mayoría a: alerta, prohibición de uso, prohibición de publicidad y fabricación, retiro del mercado y seguimiento de eventos adversos. Conclusiones. Se evidenció un número destacable de incidentes de productos médicos subestándares, falsificados, no registrados y robados al inicio de la pandemia por COVID-19. La escasez de insumos, la flexibilización en los requisitos regulatorios y el aumento de la demanda son factores que pueden favorecer el incremento del número de incidentes. Las autoridades reguladoras nacionales de referencia presentaron mayores frecuencias de detección de incidentes y de aplicación de medidas sanitarias. Se observó que se debe abordar el canal de venta por internet con alguna estrategia reguladora para garantizar la distribución segura de productos médicos.

ABSTRACT Objective. Identify and analyze incidents of substandard, falsified, unregistered, and stolen medical products at the onset of the COVID-19 pandemic. Methods. Detailed search of the websites of regulatory authorities in the Americas. Identification of incidents of substandard, falsified, unregistered, and stolen medicines and medical devices (including in vitro diagnostics). The types of products were determined, as were the stages in the supply chain where they were detected, and the actions taken by authorities. Results. A total of 1 273 incidents were identified in 15 countries (1 087 substandard, 44 falsified, 123 unregistered, and 19 stolen products). The largest number of incidents involved medical devices, disinfectants, and antiseptics. The most frequently reported point in the supply chain was online purchasing. The principal measures taken by the regulatory authorities were: alerts, prohibition of use, prohibition of advertising and manufacture, recall, and monitoring of adverse events. Conclusions. A substantial number of incidents involving substandard, falsified, unregistered, and stolen medical products at the onset of the COVID-19 pandemic were identified. Shortages of supplies, easing of regulatory requirements, and increased demand are factors that may have led to an increase in the number of incidents. The national regulatory authorities of reference reported more frequent detection of incidents and more frequent application of health measures. A regulatory strategy is needed in order to address online sales and ensure the safe distribution of medical products.

La fiebre Chikungunya es causada por un arbovirus ARN perteneciente a la familia Togaviridae del género alphavirus, llamado “virus del chikungunya”, este virus tiene como vector el Aedes aegypti y el Aedes albopictus. En su fase aguda la enfermedad se manifiesta por fiebre, artritis o artralgias severas, mialgias, cefalea, fotofobia, linfadenopatías y brotes cutáneos, los síntomas pueden progresar a una fase subaguda hasta crónica, donde persisten las manifestaciones articulares y la fatiga. Se realizó una revisión sistemática en las bases de PubMed, Cochrane, Dovepress y SciELO, utilizando las palabras claves: chikungunya y chikunguña, cruzadas con las palabras: artritis crónica y tratamiento. Se incluyeron en el estudio un total de 16 artículos, 6 artículos de revisión, 4 artículos originales, 2 ensayos clínicos, 2 reportes de caso, 1 revisión sistemática y 1 carta al editor. Entre las opciones farmacológicas, el metotrexato es el fármaco más estudiado y compite con los efectos de los AINE. Como terapias no farmacológicas se encuentran la fisioterapia y la terapia física, utilizados como complementos a la terapia farmacológica. El uso de terapias caseras, incluso la homeopatía, también podrían agregarse, atendiendo principalmente el factor psíquico y cultural de los pacientes.

Chikungunya fever is caused by an RNA arbovirus belonging to the Togaviridae family of the alphavirus genus, called "chikungunya virus", this virus is vectored by Aedes aegypti and Aedes albopictus. In its acute phase, the disease is manifested by fever, arthritis or severe arthralgia, myalgia, headache, photophobia, lymphadenopathy and skin rashes. The symptoms can progress to a subacute to chronic phase, where joint manifestations and fatigue persist. A bibliographic search was carried out in the PubMed, Cochrane, Dovepress and SciELO databases, using the keywords: chikungunya and chikunguña, crossed with the words: chronic arthritis and treatment. A total of 16 articles were included: 6 review articles, 1 systematic review, 4 original articles, 2 clinical trials, 1 letter to Editor letter and 2 case reports. Among the pharmacological options, methotrexate is the most studied drug and competes with the effects of NSAIDs. Non-pharmacological therapies are physiotherapy and physical therapy, used as complements to pharmacological therapy. The use of home therapies, including homeopathy, could also be added, mainly addressing the psychological and cultural factors of the patients.

ABSTRACT The objective of this study was to evaluate two Streptomyces spp. probiotic strains (RL8 and N7) and four highly-diluted bioactive compounds (HDBC) in the growth, survival, and modulation of the microbial content in culture water and hepatopancreas of juvenile white shrimp Penaeus vannamei. An experimental design was applied with five treatments in triplicate, including T1: (RL8+N7); T2: [(ViP-7C+ViA-7C) + (PhA-7C+SiT-7C)]; T3: [(ViP-7C+ViA-7C) + (PhA-7C+SiT-7C) + (N7)]; T4: [(ViP-7C+ViA-7C) + (PhA-7C+SiT-7C) + (RL8)] and T5 as the control without actinobacteria or HDBC. T2 showed significant differences (P < 0.5) in height increase compared to the other treated and control groups. The organisms in T2, T3, and T4 recorded higher weight gain compared to T1 and T5. A survival rate from 94.13 ± 2.12 to 99.01 ± 2.45% was obtained with a significant difference (P < 0.05) between T1, T2, and T3, concerning the untreated control (T5). A significant decrease in Vibrio spp. the content was observed in water and shrimp in T1 and T2 concerning the control. The heterotrophic bacterial count in hepatopancreas increased with all treatments compared to T5. Our results suggest a positive synergy between the HDBC mixture [(ViP-7C+ViA-7C) + (PhA-7C+SiT-7C)] and N7 Streptomyces sp. strain, whose probiotic action has been previously demonstrated by improving culture conditions for P. vannamei juveniles in terms of growth, survival, and reduction of potentially pathogenic bacteria.

RESUMO Objetiva-se analisar o processo de implantação, situação atual e perspectivas do Programa de Homeopatia, Acupuntura e Medicina Antroposófica (PRHOAMA) da rede pública de saúde de Belo Horizonte (Brasil) segundo as diretrizes da Política Nacional de Práticas Integrativas e Complementares (PNPIC). Realizou-se estudo de caso por meio de análise documental de 32 textos oficiais; dados secundários obtidos pelo número de profissionais e procedimentos ofertados em sistemas de informação em saúde; e realização de um grupo focal com profissionais do PRHOAMA. O programa foi implantado em 1994 nas Unidades Básicas de Saúde (UBS), configurando-se uma experiência pioneira no Brasil. As práticas são realizadas exclusivamente por médicos, o que diverge das recomendações da PNPIC, cujo modelo preconizado é o multiprofissional. O processo de institucionalização do PRHOAMA é parcial, não se configurando uma política pública consolidada. O PRHOAMA atende às diretrizes da PNPIC, tais como ênfase na Atenção Primária, divulgação e informação sobre as Práticas Integrativas e Complementares em Saúde (Pics). Entretanto, é necessário avançar na promoção do acesso aos medicamentos homeopáticos, na definição de mecanismos de financiamento e na ampliação da equipe gestora e de profissionais.

ABSTRACT The objective of this study was to analyze the process of implementation, the current situation and perspectives of the Homeopathy, Acupuncture and Anthroposophical Medicine Program (PRHOAMA) in public health service in Belo Horizonte (Brazil) considering the guidelines of the National Policy for Integrative and Complementary Practices (PNPIC). The case study was carried out through document analysis of 32 official texts, secondary data (number of professionals and procedures offered) in health information systems and a focus group with professionals of PRHOAMA. The program was implemented in 1994, in Basic Health Units (UBS), configuring itself as a pioneering experience in Brazil. Practices are performed exclusively by physicians, which diverges from the recommendations of the PNPIC, whose recommended the ideal model is multi-professional. PRHOAMA’s institutionalization process is partial, not constituting a consolidated public policy. PRHOAMA complies with the PNPIC guidelines, such as emphasis on Primary Care, dissemination and information about Complementary Therapies. However, it is necessary to advance in the promotion of access to homeopathic medicines, in the definition of financing mechanisms and in the expansion of the management team and professionals.

Resumen El objetivo del presente estudio fue investigar el uso de preparaciones homeopáticas para reducir los efectos nocivos causados por los residuos de herbicidas de auxina en la germinación de semillas y el desarrollo temprano de plántulas de pepino. El diseño estadístico fue completamente al azar (DIC) en un esquema factorial 3x5+2, con cuatro repeticiones. Los tratamientos fueron la combinación de tres preparados homeopáticos (Nux vomica, Carbo vegetabilis y Arsenicum album), en cinco dinamizaciones centesimales (6CH; 12CH; 18CH; 24CH y 30CH), más dos testigos (T0= agua destilada y TH= herbicida (Artys™) sin tratamiento homeopático). Cada unidad experimental consistió en cajas de acrílico transparente (Gerbox™) con 25 semillas de pepino, distribuidas en dos hojas de papel para germinación y humedecidas con tratamientos homeopáticos. Las unidades experimentales se mantuvieron en cámara de germinación DBO (ambiente controlado a 25 ºC y 12 h luz). Al décimo día después de la instalación del experimento se evaluaron las siguientes variables: porcentaje de germinación, longitud de brotes, longitud de raíces, fitointoxicación, porcentaje de plántulas muertas y masa seca total. El tratamiento homeopático de semillas de pepino contaminadas con herbicida picloram + 2,4-D (Artys™) provoca cambios positivos, provocando efectos interesantes en la germinación de las semillas, pero no es eficiente para la neutralización total del efecto causado por el herbicida picloram + 2,4-D y desarrollo de plántulas tempranas de pepino. Sin embargo, para algunas variables los resultados no son concluyentes con los preparados (Nux vomica, Carbo vegetabilis y Arsenicum album) y sus ultradiluciones (6CH, 12CH, 18CH, 24CH y 30CH), requiriendo más investigación para evaluar y describir la complejidad de propiedades inherente al tratamiento homeopático.

Abstract The aim of the present study was to investigate the use of homeopathic preparations to reduce the harmful effects caused by auxin herbicide residues on seed germination and early development of cucumber seedlings. The statistical design was completely randomized (DIC) in a 3x5+2 factorial scheme, with four replications. The treatments were the combination of three homeopathic preparations (Nux vomica, Carbo vegetabilis and Arsenicum album), in five centesimal dynamizations (6CH; 12CH; 18CH; 24CH and 30CH), plus two controls (T0= distilled water and TH = herbicide (Artys™) without homeopathic treatment). Each experimental unit consisted of transparent acrylic boxes (Gerbox™) with 25 cucumber seeds, distributed over two sheets of paper for germination and moistened with homeopathic treatments. The experimental units were kept in a BOD germination chamber (in a controlled environment at 25 ºC and 12 ho of light). On the tenth day after the installation of the experiment, the following variables were evaluated: percentage of germination, shoot length, root length, phytointoxication, percentage of dead seedlings and total dry mass. The homeopathic treatment of cucumber seeds contaminated with picloram + 2,4-D herbicide (Artys™) causes positive changes, causing interesting effects on seed germination, but it is not efficient for the total neutralization of the effect caused by the herbicide 2 picloram + 2,4-D and development of early cucumber seedlings. However, for some variables, the results are inconclusive with the preparations (Nux vomica, Carbo vegetabilis and Arsenicum album), and their ultradilutions (6CH, 12CH, 18CH, 24CH and 30CH), requiring more research to evaluate and describe the complexity of properties inherent to homeopathic treatment.

Abstract Soybean is the main oilseed crop in the world, and one of the main challenges for its production is the Anticarsia gemmatalis management, especially in agroecological production systems. In this study, it was analyzed the impact of dynamized solutions applied to soybean plants and pro-vided as food to A. gemmatalis on insect biology. Solutions tested include: Calcarea carbonica 4CH, Carbo vegetabilis 12CH, Staphysagria 4CH, A. gemmatalis nosode 12CH, Soybean nosode 4CH, and control of distilled water. Biological characteristics analyzed include: weight of caterpillars at the beginning and end of the 4th instar, dry weight of pupa, caterpillar length at 4th instar, duration of cycle, emergence of adults, fecundity of females, and ingestion, ingested food conversion efficiency, and efficiency of digested food conversion. At the beginning and at the end of the 4th instar, caterpillars fed soybean leaves treated with homeopathic substances showed reduced body weight relative to the distilled water control. The dynamized solutions tested are promising as an efficient alternative method for the control of A. gemmatalis, promoting lower conversion of food into biological efficiency and biomass.

ABSTRACT Purpose: to characterize the population with autism spectrum disorder and the Psychosocial Care Network. Methods: a study conducted with patients presented with autism spectrum disorder up to 18 years old treated at the health network in Taboão da Serra, Brazil. Participants’ data were collected from medical records of the Psychosocial Care Network for Children of that city, authorized by the Municipal Department of Health, and quantitatively analyzed. Results: altogether, there were 237 patients with autism spectrum disorder in the said health network by April 2019. Of these, 188 were treated at the Psychosocial Care Network for Children, 110 of them with weekly therapy. There was a predominance of males (73.63%), age range from 3 to 10 years, with a higher percentage of 5-year old (17.27%) patients, and a mean treatment time of 32 months. The youngest age was 2 years old. Half the sample (50%) had weekly therapy and received homeopathic medication; 24 users (21.81%) were referred by speech-language-hearing therapists and 19 (17.27%), by the school they attended. Final Considerations: although the Psychosocial Care Network for Children is the reference in the region, it is known that this facility alone cannot meet all needs of individuals with autism spectrum disorder. A service network coordinated according to patient’s individual needs and the region's reality would ensure their expected rights, decrease public spending, and enable these users to occupy not only one but many places in society.

RESUMO Objetivo: caracterizar a população com Transtorno do Espectro Autista e a Rede de Atenção Psicossocial de Taboão da Serra-SP. Métodos: estudo realizado com usuários da rede de saúde de Taboão da Serra com Transtorno do Espectro Autista com até 18 anos. Os dados dos participantes foram coletados dos prontuários do Centro de Atenção Psicossocial Infantil de Taboão da Serra com autorização da Secretaria Municipal de Saúde e as informações coletadas foram analisadas por vertente quantitativa. Resultados: o total de usuários com Transtorno do Espectro Autista na referida rede de saúde em abril de 2019 foi de 237. Destes, 188 realizavam atendimento no Centro de Atenção Psicossocial infantil, 110 em atendimento semanal. Verificou-se predominância do sexo masculino (73,63%), faixa etária de 3 a 10 anos com maior porcentagem em 5 anos (17,27%), e tempo médio de atendimento de 32 meses. a menor idade encontrada foi 2 anos de idade. Metade da amostra (50%) concentra-se em atendimento semanal e abordagem medicamentosa da homeopatia. Foram encaminhados 24 usuários (21,81%) pelo fonoaudiólogo e 19 (17,27%) pela escola. Considerações Finais: apesar da referência do território ser o Centro de Atenção Psicossocial infantil sabe-se que este equipamento por si só não atende a todas as necessidades dos indivíduos com Transtorno do Espectro Autista. Utilizar uma rede de serviços articulada segundo a demanda individual do paciente e a realidade do território garantiria os direitos almejados, diminuição de gastos públicos e permitiria a ocupação destes usuários não mais em um único lugar, mas sim “lugares”.

Abstract Residues are generated after the processing of citrus fruits and can be used for essential oil extraction. Thus, the objective of this work was to evaluate the composition, yield, and quality of the proven oil of 30 orange varieties, as an alternative for the better use of its residues. The peels were crushed and subjected to hydrodistillation in a Clevenger-type. The samples were submitted to an Entirely Randomized Design (DIC) and the results were analyzed in Analysis of Variance, Principal Component Analysis, and Hierarchical Cluster Analysis. The greatest gains in essential oil were yielded by the varieties Valencia IAC (5.57%), Pera DP 06 (4.75%), Hamlin 20 (4.58%), and Pera DP 25 (4.28%). Valencia IAC has the potential to extract up to 7.24 kg of essential oil per ton of orange. Limonene represents 93.18 to 99.61% of the oil components, being the major compound among all varieties. Some varieties did not describe secondary compounds or more than one. These components are highly antioxidant and of great importance in the production of cosmetics, personal care products, homeopathy, help gastrointestinal diseases, among other uses. It is possible to conclude that the varieties have different compounds and oils, even when submitted to the same drying and oil extraction process, being the intrinsic characteristics of each variety.

Resumo Após o processamento dos citros, são gerados resíduos que podem ser utilizados na extração do óleo essencial. Assim, o objetivo deste trabalho foi avaliar a composição, o rendimento e a qualidade do óleo comprovado de 30 variedades de laranja, como alternativa para o melhor aproveitamento dos resíduos. As cascas foram trituradas e submetidas à hidrodestilação em máquina tipo Clevenger. As amostras foram submetidas a um Delineamento Inteiramente Casualizado (DIC), e os resultados foram analisados em Análise de Variância, Análise de Componentes Principais e Análise de Agrupamento Hierárquico. As variedades Valência IAC (5,57%), Pera DP 06 (4,75%), Hamlin 20 (4,58%) e Pera DP 25 (4,28%) apresentaram os maiores ganhos em óleo essencial. Valência IAC tem potencial para extrair até 7,24 kg de óleoessencial por tonelada de laranja. O limoneno representa entre 93,18 e 99,61% do óleo, sendo ocomposto majoritário entre as variedades. Algumas variedades não descrevem compostos secundários, ou mais de um composto secundário. Esses componentes são altamente antioxidantes e degrande importância na produção de cosméticos, produtos de higiene pessoal,homeopatia, uso em doenças gastrointestinais, entre outros. É possível concluir que as variedadespossuem diferentes compostos e óleos, mesmo quando submetidas ao mesmo processo de secagem e de extração do óleo, sendo as características intrínsecas de cada variedade.

Abstract Studies and innovations on alternative feed additives, especially on homeopathic remedies have been highlighted in order to replace or reduce the use of antibiotics in pig production. This paper aimed to assess the addition of homeopathic products in pig diet and their effects on the growth performance, serum metabolites, nutrient and energy digestibility, carcass traits and meat quality. A total of 60 immunocastrated male pigs, weighing on average 30.91 ± 0.95 kg, were distributed in two treatments, 10 replicates and three animals/experimental unit. There was no effect (P≥0.05) of treatment on the growth performance and serum metabolites. The percentage of acid-insoluble ash recovered in the diet was greater (P≤0.01) in diets containing homeopathic products. The apparent digestible energy of diets containing homeopathic products was reduced (P≤0.01) in the growing phase and reduced (P≤0.01) the apparent digestibility coefficients of dry matter, crude protein, soluble neutral and acid detergent fibers, and gross energy in the growing and finishing phases. Pig that received diets with homeopathic products had higher (P≤0.05) amount of meat, percentage of meat and marbling. The use of homeopathic products in diets improves the percentage and quality of meat, as well as the marbling of the pig carcass, maintaining the performance.

Resumen Las esporas extrarradicales de hongos micorrícicos arbusculares (AM) a menudo son parasitados por una amplia gama de microorganismos del suelo. Sin embargo, los informes sobre la parasitación de estructuras intrarradicales de hongos AM son muy raros. Al examinar la colonización de AM en raíces de Cuminum cyminum y Sambucus nigra que crecen en el jardín de plantas medicinales del Centro de Investigación de Plantas Medicinales en Homeopatía de Nilgiris, encontramos bobinas de hifas de hongos AM, bobinas arbusculadas, vesículas y esporas intrarradicales colonizadas por hongos endófitos septados oscuros (DSE) que coexistían con hongos AM. Las hifas de hongos AM eran significativamente más anchas que los hongos DSE. La colonización de diferentes estructuras fúngicas AM varió significativamente entre las dos especies de plantas. Además, el porcentaje de estructuras fúngicas AM colonizadas se correlacionó linealmente con la abundancia de estas estructuras. Se ilustra la colonización de las estructuras intrarradicales de hongos AM y la importancia de este fenómeno necesita mayor aclaración.

Abstract Extraradical spores of arbuscular mycorrhizal (AM) fungi are often parasitized by a wide range of soil microorganisms. However, reports on the parasitization of intraradical structures of AM fungi are very rare. While examining AM colonization in roots of Cuminum cyminum and Sambucus nigra growing in the medicinal plants garden of the Centre of Medicinal Plants Research in Homeopathy of the Nilgiris, we found that AM fungal hyphal coils, arbusculate coils, vesicles, and intraradical spores are colonized by dark septate endophytic (DSE) fungi which were co-occurring with AM fungi. The AM fungal hyphae were significantly wider than the DSE fungi. Colonization of different AM fungal structures significantly varied between the two plant species. Moreover, the percentage of colonized AM fungal structures was linearly correlated to the abundance of these structures. The colonization of the intraradical structures of AM fungi is illustrated and the significance of this phenomenon needs further elucidation.
