Parasit VectorsMar 16; 10 1pp: Cell Death DisJun 18; 9 7pp: Como citar este artigo. Saint Louis encephalitis virus SLEV is an encephalitogenic arbovirus that taxonomically belongs to the Japanese encephalitis virus complex within the genus Flavivirusfamily Flaviviridae 2.

Am J Trop Med Hyg. 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, Louis encephalitis chimeric virus and the use of chimeras as a diagnostic tool.

Our results demonstrate the widespread distribution of this virus, and they agree with previous studies conducted on humans and wild vertebrates in Brazil especially in the Brazilian Amazon region reporting a prevalence of HI antibodies ranging from 0.

Mosquitoes of the genus Culex and wild birds serve as the primary amplification host for SLEV 21,24, The plates were incubated for seven and six days, respectively.

This study investigated the immunity of horses against SLEV in encefaltiis municipalities of the Brazilian Amazon region and in the State of Mato Grosso do Sul in order to contribute to a better understanding of the epidemiology of this virus.

Samples containing neutralizing antibodies against both viruses were considered to be positive for one of them when the antibody titer was four times higher than that obtained for the other virus; otherwise, the sample was said to present CR against the virus in question 6.

The known specificity of neutralization tests generally permits the identification 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.

In the HI test, MR was observed in However, despite the importance of the PRNT for evaluating the efficacy of vaccines and for confirming serodiagnoses due to its high specificity and sensitivity, the lack of a standard procedure and of diagnostic criteria results in wide variations between laboratories 8, 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.

Always seek the advice of your physician or other qualified health provider prior to starting any new treatment or with questions regarding a medical condition.
