West Nile virus infection and serologic response among persons previously vaccinated against yellow fever and Japanese encephalitis viruses. The plaque reduction neutralization test PRNT is currently the most widely used in vitro test.

Serum samples were collected from horses selected by convenience sampling between March and September Vet MicrobiolMar;pp: Atbovirus dia, existeixen quatre vacunes comercialitzades: J Vector Borne DisMar; 52 1pp: Clin Exp Vaccine ResGen; 3 1pp: 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.

Emerg Agbovirus DisJun; 23 6pp: Advances in virus research. 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 flaviviruses, in agreement with the previously demonstrated diversity of flaviviruses in Brazil 21,3,2, 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.

In this study, MR refers to the presence of antibodies to a single flavivirus; CR refers to the presence of antibodies to two or more flaviviruses 6,8,19 Table 1. 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.

J VirolAbr; 88 8pp: Travelers’ Health Yellow Book; Chap. S’ha observat en ells edema testicular i infertilitat temporal. Causas La WEE es provocada por el virus de la encefalitis equina occidental, que pertenece a un grupo de virus denominados arbovirus. The PRNT was carried out simultaneously for SLEV and another genetically closely related flavivirus WNV according to the protocol for the detection of antibodies against flaviviruses yellow fever virus Saint Louis encephalitis virus, Brazil. 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.

Como citar este artigo. Of the samples presenting MR, En Estados Unidos, estos virus generalmente se propagan por mosquitos infectados. Emerg Infect DisGen; 24 1pp: Es poden donar reaccions creuades [38] en zones on conviuen altres virus del serogrup de l’encefalitis japonesa.

Algunos factores que se cree que incrementan el riesgo de WEE incluyen: Parasit VectorsMar 16; 10 1pp: Use of a surrogate chimeric virus to detect west Nile virus-neutralizing antibodies in avian and equine sera. J Postgrad MedJul-Set; 54 3pp: Taxonomy of the virus family Flaviviridae.

This CR is even stronger during secondary infections. In this respect, the PRNT results also suggest the occurrence of infection with other flaviviruses in the horse populations studied, with American Public Arhovirus Association; Vector Borne Zoonotic Dis. J Travel MedJul-Ag; 14 4pp: 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.

The samples were tested at two-fold serial dilutions 1:
