TAURO, Laura et al. Serological detection of St. Louis encephalitis virus and West Nile virus in equines from Santa Fe, Argentina. Mem. Inst. Oswaldo Cruz [online]. 2012, vol.107, n.4, pp.553-556. ISSN 0074-0276. http://dx.doi.org/10.1590/S0074-02762012000400019.
St. Louis encephalitis virus (SLEV) and West Nile virus (WNV) present ecological and antigenic similarities and are responsible for serious human diseases. In addition, WNV is a significant pathogen in terms of equine health. The purpose of our study was to analyse the seroprevalence of SLEV and WNV in equine sera collected in Santa Fe Province, Argentina. The seroprevalence determined using the plaque reduction neutralisation test was 12.2% for SLEV, 16.2% for WNV and 48.6% for a combination of both viruses. These results provide evidence of the co-circulation of SLEV and WNV in equines in Santa Fe.
