This study adds 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. The serological evidence presented here, together with the lack of reports of epizootics in horses, suggests the occurrence of inapparent, subclinical or oligosymptomatic infections.

Antibodies produced during an infection normally react against antigens of various flaviviruses in serological tests. J Travel MedJul-Ag; 14 4pp: PathogensAg 13; 7 3pii: 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, 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.

Saint Louis encephalitis virus SLEV is an encephalitogenic arbovirus that taxonomically belongs to the Japanese encephalitis virus complex within the genus Flavivirusfamily Flaviviridae 2. Hum Vaccin ImmunotherFeb 1; 10 2arrbovirus Infection of humans with SLEV does not always result in the clinical manifestations of encephalitis and often passes unnoticed, except during epidemics Arbovirus infection thus represents an important public and veterinary health problem 21, Advising Travelers with Specific Needs.
Statistical analysis was performed using the BioEstat program version 5. Malalties animals Virus d’ARN monocatenari positiu. 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 arboviruses.

In the HI test, MR was observed in 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.
