J NeuroinflammationAg 14; 14 1pp: This study arbovirua new data regarding the immunity of horses against SLEV in Brazil, and it confirms the wide distribution of SLEV and the diversity of flaviviruses in the country, as well as the apparent absence of disease in SLEV-infected horses. It should be emphasized that the interpretation of flavivirus serological results requires caution because of the complex combination of cross-reactivity CR between antibodies and sequential secondary infections with different flaviviruses 8.

The HI test also showed that the horse populations studied possessed an immune response pattern consistent with that of a population exposed to infection with different arbovirud, in agreement with the previously demonstrated diversity of flaviviruses in Brazil 21,3,2, Horses, which are typically dead-end hosts of other encephalitogenic arboviruses, do not show elevated viremia or clinical disease when infected with SLEV through the bite of a mosquito or subcutaneous inoculation 16, Virus de l’encefalitis japonesa.

In this respect, the PRNT results also suggest the occurrence of infection with other flaviviruses in the horse populations studied, with This study, the first of this type conducted in Brazil, detected HI and neutralizing antibodies against SLEV in naturally infected horses in five geographically distant municipalities Figures 12 and 3.

American Public Health Association; Euro SurveillJul 12; 17 28pii: Avui dia, existeixen quatre vacunes comercialitzades: The small number of human cases of SLEV infection is probably due to the occurrence of inapparent infection, but it may also be the result of subdetection of clinical cases due to the difficulty of making a differential diagnosis.

SLEV is widely distributed throughout the western hemisphere; however, strains isolated in the United States and Canada are apparently more virulent than those isolated in the Caribbean and Central and South America 4. The known specificity of neutralization tests generally permits the lor of a viral agent responsible for manifestations during primary infection, but this fact does not apply to secondary infections when the test is used for serodiagnosis in vitro.
