Revascularização clínica e intervencionista no acidente vascular cerebral isquêmico agudo: opinião nacional

The Brazilian Stroke Society constituted a committee composed by specialists from different areas of Brazil that emitted a viewpoint called National Opinion, considering the interventional procedures and thrombolysis in the treatment of the acute ischemic stroke. This study presents the conclusions of this committee.

Frequency of Toxoplasma gondii antibodies in tufted capuchin monkeys (Cebus apella nigritus) from an ecological station in the State of São Paulo, Brazil

A toxoplasmose é uma das zoonoses mais difundidas no mundo, causada pelo Toxoplasma gondii, um protozoário parasita intracelular obrigatório. Uma alta porcentagem de animais apresenta anticorpos específicos causados por exposição prévia, levando a uma infecção crônica. Os felídeos são os hospedeiros definitivos e outros animais homeotérmicos, incluindo os primatas, são os hospedeiros intermediários. Este estudo objetivou determinar a prevalência da infecção por T. gondii em macacos-prego (Cebus apella nigritus) de vida livre da Estação Ecológica localizada na Mata de Santa Teresa, Ribeirão Preto, SP, Brasil. Anticorpos anti-T. gondii foram pesquisados pelo método de aglutinação direta modificada (MAT) em amostras de soro de 36 macacos-prego, utilizando-se o título oito como de corte. Dos animais estudados, 3/36 (8,33%; IC95% 3,0-21,9%) apresentaram anticorpos anti-T. gondii, todos com título 32. Nenhuma diferença significativa (P>0,05) foi observada com relação ao sexo (1/3 machos e 2/3 fêmeas), e à idade (1/3 jovens e 2/3 adultos). Assim, estes resultados demonstram alta prevalência de anticorpos anti-T. gondii em primatas no estado de São Paulo.

Seroprevalence and risk factors associated with neosporosis in sheep and dogs from farms

This study aimed to establish the seroprevalence and risk factors associated with neosporosis in sheep and dogs from rural properties. 1497 blood samples were collected from sheep and 42 from dogs that cohabited with sheep from 16 farms located in the central region of São Paulo State, Brazil. For the detection of N. caninum antibodies it was performed the indirect fluorescent antibody test (IFAT >= 25). For the epidemiological study it was applied a questionnaire for the owners or responsible from the sheep and dogs regarding informations related to neosporosis. The seroprevalence obtained out of the 1497 sheep sera tested was 8.0% (CI95% = 6.7-9.2%) and out of the 42 dogs 4.8% (CI95% = 0-7.2%). Variables statistically related to seropositivity for N. caninum in sheep were: dams well as water supply (P = 0.0004; OR = 2.15), presence of other domestic canids (P = 0.0013; OR = 2.38) and presence of reproductive problems (P = 0.0031; OR = 1.75).

Exposure to rabies virus in a population of free-ranging capuchin monkeys (Cebus apella nigritus) in a fragmented, environmentally protected area in southeastern Brazil

The aim of this study is to assess the frequency of rabies antibodies in free-ranging capuchin monkeys (Cebus apella nigritus) in a fragmented, environmentally protected, rural area of southeastern Brazil. Thirty-six free-ranging monkeys were tested by the rapid fluorescent focus inhibition test for detection of antibodies against rabies virus. Four individuals (11.11 %) had neutralizing antibody titers a parts per thousand yen0.25 IU/mL, demonstrating rabies virus exposure.

Transient expression of rabies virus G-glycoprotein using BHK-21 cells cultured in suspension

Objective To assess the expression of rabies virus G-glycoprotein (RVGP) expression using Semliki Forest virus as a vector in combination with BHK-21 cells cultured in suspension. Results A multilevel factorial design was used to quantify effects of temperature (33–37 C), fresh medium addition after the viral adsorption step (100–200 % with respect to the initial cell suspension volume before infection) and harvest time (8–40 h) on RVGP production. Experimental runs were performed in 24-well cell culture plates at a multiplicity of infection (MOI) of 16. An additional experiment in spinner-flask was performed at MOI of 9, using the optimal conditions determined in cell culture plates. Values for temperature, fresh medium addition and harvest time of 33 C, 100 % and 16 h, respectively, ensured the optimal RVGP production in culture plates. The volumetric yield (239 ng ml-1 ) in these conditions was higher than that reported previously for adherent cell culture. In spinner-flasks, the volumetric yield was improved (559 ng ml-1 ). Conclusion These results establish the basis for designing bioprocess to produce RVGP.
