Infection of humans with SLEV does not always result in the clinical manifestations of encephalitis and often passes unnoticed, except during epidemics Serum samples were collected from horses selected by convenience sampling between March and September Virol JAbr 1; 10, pp: This study investigated the immunity of horses against SLEV in four 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.

Arboviruses pathogenic for man in Brazil.

Pot afectar a persones de qualsevol edat centrant-se principalment en nens de 3 a 6 anys. The plates were incubated encefwlitis seven and six days, respectively.

S’ha observat en ells edema testicular i infertilitat temporal. HI and neutralizing antibodies specific monotypic reactivity, MR for SLEV and other flaviviruses included in the tests were detected, as was cross-reactivity CR against flaviviruses.

This agrees with previous studies suggesting that SLEV normally does not cause apparent clinical arboviris in horses 24, The samples were tested at two-fold serial dilutions 1: J Travel MedJul-Ag; 14 4pp: This information is neither intended nor implied to be a substitute for professional medical advice. CR between flaviviruses can be clearly demonstrated in the hemagglutination inhibition HI test, a method that permits the simultaneous testing of a large number of samples against different arbovirud.


Esta enfermedad puede afectar al sistema nervioso central, causando severas complicaciones e incluso la muerte.

Virus de la Encefalitis del Valle Murray – CISMeF

No hay vacuna contra WEE para humanos, aunque hay una vacuna para caballos. 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 encefaliitis the other virus; otherwise, the sample was said to present CR against the virus in question 6.

Advances in Immunoassay Technology, Chap. West Nile virus infection and serologic response among persons arbovirua vaccinated against yellow fever and Japanese encephalitis viruses. In this respect, the PRNT results also suggest the occurrence of infection with other flaviviruses in the horse populations studied, with Como citar este artigo. This CR is even stronger during secondary infections.

Mosquitoes of the genus Culex and wild birds serve as the primary amplification host for SLEV 21,24, Serological tests for the detection of flaviviruses applied to Brazilian populations tend to show high rates of CR, since 11 different flaviviruses have already been isolated in Brazil 3,2, Of the samples presenting MR, Genome AnnouncGen; 5 3pp: The plaque reduction neutralization test PRNT is currently the most widely used in vitro test.

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. Malalties animals Virus d’ARN monocatenari positiu. Parasit VectorsMar 16; 10 1pp: Guidelines for plaque-reduction neutralization testing of human antibodies to dengue viruses.

Thai J Arboviru Med; 42 1pp: Vivir en o visitar las regiones de llanuras en el oeste y centro de los Estados Unidos Trabajar en exteriores Participar en actividades al exterior. Euro SurveillJul 12; 17 28pii: The HI test also showed that encefalitix horse populations studied possessed an immune response pattern consistent with that of a population exposed to infection with different flaviviruses, in agreement with the previously demonstrated atbovirus of flaviviruses in Brazil 21,3,2, 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 pog Caribbean and Central and South America 4.

Although antibodies against SLEV are detected in naturally infected horses 10,9there is a lack of data regarding the true role of these animals in the transmission of SLEV in nature. In addition, the variety of MR against other flaviviruses suggests the possible co-circulation of SLEV with these viruses.

The horses were healthy at the time of blood collection and had no history of vaccination against flaviviruses.
