RESUMO O projeto ‘Saúde Única no Pantanal: participação da sociedade na vigilância de emergência de zoonoses como efeito pós-incêndios no território e formação de estratégias integradas’ objetivou integrar representações institucionais e da sociedade local; ampliar o uso do Sistema de Informação em Saúde Silvestre (SISS-Geo) para o monitoramento da fauna; identificar áreas prioritárias para vigilância de zoonoses e construir caminhos envolvendo a Saúde Única (SU). Realizou webinário, apontando a necessidade de eventos mais amplos com a participação de lideranças em cada um dos territórios escolhidos. Foram executados seminários e oficinas nos estados de Mato Grosso do Sul (MS), com a participação de gestores do serviço de saúde da Província de Santa Cruz, Bolívia, e de Mato Grosso. A representatividade dos diferentes segmentos nos eventos possibilitou a articulação de cidadãos e gestores locais. Nas comunidades tradicionais, foi possível abordar os impactos dos incêndios e dar oportunidade para que essas pessoas manifestassem suas prioridades e demandas de saúde, antes e depois dos incêndios. A Oficina Síntese realizada em Corumbá, MS possibilitou a devolutiva dos resultados e a integração com representantes de diferentes instituições do Brasil e da Bolívia, além da prospecção e priorização de enfermidades a serem incorporadas em modelo de SU para o Pantanal e fronteira oeste do Brasil.

ABSTRACT The project ‘One Health in the Pantanal: society’s participation in the emergency surveillance of zoonoses emergency as a post-fire effect in the territory and the formation of integrated strategies’ aimed to integrate institutional representations and local society; expand the use of Wildlife Health Information System (SISS-Geo) for fauna monitoring; identify priority areas for zoonosis surveillance and build paths involving One Health (OH). A webinar was held, highlighting the need for broader events with the participation of leaders in each of the chosen territories. Seminars and workshops were held in the states of Mato Grosso do Sul (MS), with the participation of health service managers from the Province of Santa Cruz, Bolivia, and Mato Grosso. The representation of different segments at the events enabled the articulation of citizens and local managers. In traditional communities, it was possible to address the impacts of the fires and provide the opportunity for these people to express their health priorities and demands, before and after the fires. The Synthesis Workshop held in Corumbá, MS allowed the feedback of results and integration with representatives from different institutions in Brazil and Bolivia, and prospecting and prioritization of illnesses to be incorporated into the OH model for the Pantanal and western border of Brazil.

Objective: to analyze the characteristics and temporal trend of mortality rates in the population aged 5 to 14 years in Mato Grosso state and Brazil, from 2009 to 2020. Methods: ecological time-series study, based on data from Mortality Information System. Descriptive and trend analysis were performed, using the regression model by inflection points (JoinPoint regression) and calculating the average change in the period (average annual percentage change – AAPC). Results: in Brazil and Mato Grosso, deaths were predominantly male, preventable and due to external causes. A decreasing trend was identified in Brazil (5 a 9 years AAPC: -2,9; 95%CI -4,3;-1,6 and 10 a 14 years AAPC: - 2,5; 95%CI -3,3;-1,8) and stationary in Mato Grosso (5 a 9 years AAPC: -2,0; 95%CI -5,6;1,7 and 10 a 14 years AAPC: -0,1; 95%CI -5,9;6,1). Conclusion: the stationarity of the mortality trend at high levels demands urgent interventions to reduce it.

Resumo Algumas espécies de Bartonella têm os felinos como principais hospedeiros reservatórios. Tais patógenos são transmitidos ao homem por intermédio da arranhadura ou mordedura de gatos e entre os gatos, por meio da pulga Ctenocephalides felis. O objetivo deste estudo foi investigar a ocorrência de DNA de Bartonella spp. em gatos de abrigos e seus ectoparasitas e a relação entre o estado de infecção dos gatos e dos ectoparasitas albergados por estes. Material genético bacteriano foi detectado em 47,8% das amostras de sangue de gatos, 18,3% das pulgas C. felis, 13,3% dos "pools" de ovos de pulgas e 12,5% dos "pools" de piolhos. DNA de B. henselae e B. clarridgeiae foi detectado em pulgas, e B. henselae, B. clarridgeiae e B. koehlerae, em amostras de sangue de gatos. Gatos infestados por ectoparasitas que carreavam DNA de Bartonella spp. demonstraram aproximadamente o dobro de chance de estarem infectados. Esses resultados indicam que os gatos de abrigos têm alta prevalência de infecção por espécies de Bartonella, capazes de causar doenças no homem. E também destacam a importância do controle e prevenção da infestação por ectoparasitas, no intuito de prevenir a infecção em gatos e humanos.

Abstract Feline Bartonella can be transmitted to humans through cat scratches or bites, and between cats, by the flea Ctenocephalides felis. The study was carried out in order to investigate the occurrence of Bartonella DNA in cats living in shelters and their ectoparasites and the relationship between the infection status of cats and ectoparasites they host. Bartonella DNA was detected in 47.8% of the cat blood samples, 18.3% of C. felis fleas, 13.3% of flea egg pools and 12.5% of lice pools. B. henselae and B. clarridgeiae DNA were detected in cat fleas, while B. henselae, B. clarridgeiae and B. koehlerae were found in blood samples from bacteremic cats. Cats infested by positive ectoparasites showed approximately twice the odds of being infected. Our results indicate that shelter cats have high prevalence of Bartonella species that are known to be human pathogens. This highlights the importance of controlling infestations by ectoparasites to avoid cat and human infection.

ABSTRACT The increasing use of illicit drugs imposes a public health challenge worldwide. People who inject drugs (PWID) are more susceptible to health complications due to immunosuppression associated with drug use and non-hygienic self-administration of substances, contaminants, and liquids. PWID are subjected to increased risk of acquiring and transmitting different pathogens (frequently functioning as sentinel cases for (re)emerging pathogens), including those transmitted by arthropods and vertebrate reservoirs in unhealthy environments. A clear association between injection drug use and HIV, HBV, and HCV infections has been described; however, other infectious viral and bacterial agents have been seldomly assessed. In this study, we investigated the seroprevalence of Bartonella spp., Coxiella burnetii, and Hantavirus among 300 randomly selected PWIDs from Rio de Janeiro, as part of a multi-city cross-sectional study carried out in the 1990s. Point seroprevalences and respective 95% CIs are as follows: 9.3% for C. burnetii (95% CI: 6.0%-13.0%), 1.0% for Bartonella spp. (95% CI: 0.0%-3.0%), and 4.0% for Hantavirus (95% CI: 2.0%-7.0%). In addition to the blood-borne pathogens, the results of this study increase our knowledge on other transmissible infectious agents in PWID. The high seroprevalence of C. burnetii and Hantavirus found among PWID is intriguing and suggests the need to carry out prospective studies, including molecular analyses, to confirm these findings and allow a better understanding of the putative relevance of these zoonotic infectious agents among PWID.

ABSTRACT This study verified the occurrence of Bartonella spp. in dogs, cats, wild mammals and their ectoparasites in Petrolina and Lagoa Grande Counties, Pernambuco, located in a semi-arid region in Northeastern Brazil. Anti-Bartonella spp. antibodies were detected by indirect immunofluorescence assay (IFA) in 24.8% of dogs (27/109) and in 15% of cats (6/40). Bartonella sp. DNA was identified by PCR performed on DNA extracted from blood and ectoparasites using primers targeting Bartonella sp. gltA and ribC genes in 100% (9/9) of Pulex irritans from Cerdocyon thous, 57.4% (35/61) of P. irritans from dogs, 2.3% (1/43) of Ctenocephalides felis felis from dogs, 53.3% (24/45) of C. felis felis from cats, and 10% (1/10) of Polyplax spp. from Thrichomys apereoides. DNA sequencing identified Bartonella clarridgeiae and Bartonella henselae in C. felis felis from cats, Bartonella rochalimae in P. irritans from dog and C. thous, and Bartonella vinsoni berkhofii in P. irritans from dog.

ABSTRACT Bacillary angiomatosis (BA) is an angioproliferative disease of immunocompromised patients that usually presents as vascular tumors in the skin and subcutaneous tissues. It is caused by chronic infections with either Bartonella henselae or B. quintana. Oral cavity BA is exceedingly rare and even rarer without simultaneous cutaneous disease. We report herein the case of a 51-year-old HIV-infected man who presented severe odynophagia and an eroded lesion on the hard palate that progressed to an oronasal fistula. No cutaneous lesions were recorded. Doxycycline led to complete resolution. To the best of our knowledge, only six previous cases of oral BA without tegumentary disease have been previously reported and none of them progressed to fistula.

Introduction Over the last recent years, the number of Q fever cases have has increased throughout the world. An epidemiological investigation was performed in the area in which the first molecular documentation of Q fever in Brazil was previously reported. Methods Indirect immunofluorescence assay (IFA) and PCR of Coxiella burnetii targeting the htpAB gene were performed in samples from 14 dogs (blood); 1 cat (blood); 10 goats (blood, milk, vaginal swab and anal swab); 3 sheep (blood); and 2 horses (blood). Results Two dogs, two sheep and five goats were seroreactive. DNA was amplified from 6 milk and 2 blood samples from goats and from dogs, respectively. The sequence of the amplicons exhibited 99% sequence similarity with the homologous sequence of the htpAB gene of C. burnetii RSA 331 (GenBank - CP000890). Conclusions The results confirm C. burnetii infection in animals in Rio de Janeiro and reinforce the need for the surveillance of Q fever in Brazil.

Febre maculosa brasileira (FMB) é a mais importante e frequente doença rickettsial no Brasil. Relatamos um caso fatal de FMB em um homem negro de 32 anos de idade que morreu de choque irreversível após cinco dias de febre, cefaléia intensa, dor abdominal, e sem evidência de exantema. Amostras de baço, rim e coração coletadas na necropsia foram positivas para Rickettsia rickettsii por PCR e sequenciamento. Os autores ressaltam a necessidade de um alto índice de suspeita diagnóstica para febre maculosa em pacientes negros. Ausência de exantema não deve dissuadir os clínicos de considerar a possibilidade de FMB e iniciar a terapêutica empírica.

Brazilian spotted fever (BSF) is the most important and frequent rickettsial disease in Brazil. A fatal case of BSF is reported in a 32-year-old black man, who died of irreversible shock after five days of fever, severe headache and abdominal pain with no rash. Spleen, kidney and heart samples collected at autopsy were positive for Rickettsia rickettsii by PCR and sequencing. The authors emphasize the need for a high index of diagnostic suspicion for spotted fever in black patients. Absence of a skin rash should not dissuade clinicians from considering the possibility of BSF and initiating empirical therapy.

Cat scratch disease (CSD) is a self limited condition characterized by fever, lymph node enlargement and less often eye involvement. Central nervous system involvement by Bartonella henselae infection is possibly an important cause of morbidity; its role as an agent of aseptic meningitis is unknown. We report a case of a 40 years-old man with CSD accompanied by aseptic meningitis and neuroretinitis. Serum indirect immmunofluorescence (IFI) assays for B. henselae were positive and the cerebrospinal fluid (CSF) analysis showed mononuclear pleocytosis and increased level of protein. Serological tests for other etiologies were negative. The patient responded well to antibiotic therapy with oral doxycicline plus rifampin and in the 12th day of hospitalization evolved to total regression of the headache and partial regression of the visual loss. Clinicians should consider CSD as a differential diagnosis when assessing previously healthy patients with aseptic meningitis associated with regional lymphadenopathy and epidemiological history of feline contact.
