Doryctobracon crawfordi (Viereck) was recorded in the states of Amapá and Roraima, Brazil. This is also the first time that this parasitoid is associated with Anastrepha atrigona Hendel from Geissospermum argenteum.

Anastrepha serpentina (Wiedemann) is recorded for the first time in citrus (Rutaceae) in Brazil. Specimens were obtained from sweet orange (Citrus sinensis) sampled in the municipalities of Belém and Capitão Poço, and from mandarin orange (Citrus reticulata) from Tomé-Açu, state of Pará, Brazil.

Contextualização: Para que sejam realizadas atividades funcionais da vida diária é primordial a manutenção do equilíbrio estático, possibilitando posturas, movimentos e respostas adequadas. Objetivos: O presente trabalho teve como finalidade avaliar e comparar, através do teste de Romberg adaptado, as oscilações do equilíbrio estático de amputados protetizados de membros inferiores com indivíduos não amputados. Método: Foram avaliados 33 indivíduos do sexo masculino com idade média de 33,38 anos, divididos em três diferentes grupos. O grupo A foi composto por 12 indivíduos amputados que utilizavam prótese transfemural. O grupo B foi formado por 9 indivíduos amputados transtibiais. O grupo controle C continha 12 indivíduos não amputados. Cada indivíduo foi filmado nos planos frontal e sagital, avaliado quadro a quadro para a seleção de momentos de maiores oscilações. As imagens selecionadas foram quantificadas através da Biofotogrametria Computadorizada, utilizando-se o programa ALCimage 2.1®. Resultados: Os resultados mostraram diferenças significativas entre as oscilações anteriores para o grupo A (transfemural) e entre as oscilações para o lado esquerdo, no grupo B. Conclusão: A partir destes resultados, conclui-se que amputados de membros inferiores apresentam uma tendência de oscilação mais significante em direção anterior e para o lado contra-lateral à prótese. Com o avanço da idade, nota-se uma menor tendência à oscilação posterior.

Background: To accomplish day-to-day functional activities, it is fundamentally important to maintain static balance, thereby enabling appropriate postures, movements and responses. Objective: The purpose of this study was to evaluate oscillations in static balance among amputees with lower limb prostheses, by means of an adapted Romberg test, and to compare such oscillations with those among individuals without amputations. Method: Thirty-three male individuals of mean age 33.38 years were evaluated, in three different groups. Group A was composed of 12 amputees who were utilizing a transfemoral prosthesis. Group B was formed by 9 individuals with a transtibial amputation. Group C (control) contained 12 normal individuals. All subjects were filmed in the frontal and sagittal planes, and their movements were evaluated frame by frame to select the moments of greatest oscillation. The images selected were quantified by means of computerized biophotogrammetry using the program ALCimage 2.1®. Results: The results showed significant differences among the anterior oscillations for the group A and among the left-side oscillations for group B. Conclusion: From these results, it was concluded that lower-limb amputees present a tendency towards more significant oscillations in the anterior direction and contralaterally to the prosthesis. With advancing age, a lesser tendency towards posterior oscillation was noted.

Intensive broiler production in tropical climates requires adequate air circulation to control heat stress. Excess of air speed may lead to dust production and reduction of air quality and, consequently, production parameters. Brazilian regulations prohibit the presence of pathogens that may deteriorate air quality, and the presence of fungi in the air inside the poultry houses is limited to 750CFU/m³. The aim of this study was to evaluate the presence of fungi in two distinct types of broiler houses. The research compared two types of air ventilation: conventional (G1) and positive tunnel ventilation (G2). The fungi were collected using a dust sampling pump, with the air flow calibrated to 1.5 L/min. The filter impregnated with dust was submitted to growth for two days using five Petri dishes. Microbiology analysis showed that there were 1,239 CFU and 2,011 CFU in G1 and G2, respectively. The different genera of fungi found and their percentages were: Penicillium 29.16%, Aspergillus 37.5% and Fusarium 29.16% in G1 and Penicillium 33.34%, Aspergillus 26.64%, Fusarium 23.34% and Neurospora 3.34% in G2.

Data on the association of schistosomiasis and hepatitis B in field-based studies are scarce. Two areas have been selected for this study: i) Queixadinha, endemic for schistosomiasis, with a population of 693 individuals, and ii) Capão, a control non-endemic area, with 515 inhabitants. Sera of all individuals in both areas were tested for hepatitis B infection, yearly, from 1994 to 1997. In the first area hepatitis B was found in 32.1% of children up to one year old and reached a peak of 68.7% in the age range of 15 to 19 years. In the control area the prevalence of hepatitis B was under 5% up to 19 years of age and the highest prevalence was observed in adults over 45. HBsAg was detected in 9.4% of the individuals living in the endemic area for schistosomiasis and in 1.4% of the controls (OR=4.98; 95%CI=3.7-6.7). The index of chronicity of HBsAg was not statistically different in the studied areas (8.1% x 7.3%; OR = 1.09; 95%CI= 0.42-3.03), nor was it different for people with and without schistosomiasis in Queixadinha (8.7% x 7.0%). We conclude that the Schistosoma mansoni infection has not altered the course of hepatitis B in the studied area.
