Phylogenetic Analysis of West Nile Virus, Nuevo Leon State, Mexico
نویسندگان
چکیده
West Nile virus RNA was detected in brain tissue from a horse that died in June 2003 in Nuevo Leon State, Mexico. Nucleotide sequencing and phylogenetic analysis of the premembrane and envelope genes showed that the virus was most closely related to West Nile virus isolates collected in Texas in 2002.

Detection of West Nile virus-specific antibodies and nucleic acid in horses and mosquitoes, respectively, in Nuevo Leon State, northern Mexico, 2006-2007.
In the last 5 years, there has been only one reported human case of West Nile virus (WNV) disease in northern Mexico. To determine if the virus was still circulating in this region, equine and entomological surveillance for WNV was conducted in the state of Nuevo Leon in northern Mexico in 2006 and 2007. A total of 203 horses were serologically assayed for antibodies to WNV using an epitope-blo...
متن کاملWest Nile Virus in Mexico: Evidence of Widespread Circulation since July 2002.
West Nile virus (WNV) antibodies were detected in horses from five Mexican states, and WNV was isolated from a Common Raven in the state of Tabasco. Phylogenetic studies indicate that this isolate, the first from Mexico, is related to strains from the central United States but has a relatively high degree of sequence divergence.
متن کاملDetection of antibodies to West Nile and Saint Louis encephalitis viruses in horses.
To the editor: West Nile virus (WNV) and Saint Louis encephalitis virus (SLEV) belong to the Japanese encephalitis an-tigenic complex (family Flaviviridae, ge-nus Flavivirus). 1-3 As with other members of this complex, WNV and SLEV are usually maintained in cycles between birds and Culex species mosquitoes. Humans, horses and other mammals are typically dead-end hosts. WNV and SLEV infections i...

متن کاملSerologic Evidence of West Nile Virus Infection in Horses, Coahuila State, Mexico
Serum samples were obtained from 24 horses in the State of Coahuila, Mexico, in December 2002. Antibodies to West Nile virus were detected by epitope-blocking enzyme-linked immunosorbent assay and confirmed by plaque reduction neutralization test in 15 (62.5%) horses. We report the first West Nile virus activity in northern Mexico.
