The West Nile Fever represents the archetype of the emergent illnesses and is distributed in many countries in the American continent. In 1937 in Uganda, Africa, situated in Nile River west, was described the first case in a human being, that provoked the Encephalitis gained this name. A threat became when the first case of the illness in American territory was discovered, in New York in 1999. From this event, the virus made making a trajectory to the south of the continent coming close to Brazil, where it has not been described yet. However, there are relates of three horses that died with the Encephalitis of the West Nile illness in Argentina in past year, that shows the importance of the monitoring of this virus in our country. The natural reservoirs of the illness are migratory birds and have as accidental host the equines and the man. Counting that, the natural reservoirs and accidental hosts can transmit the virus through the bite of insects that are represented by the mosquitoes of varied species. The project has as perspective of collect samples of birds and equines in the tropical and subtropical regions of Brazil. The captures will be carried through the team of the ICB. In association with the new laboratory standard NB3+ (level of biosecurity 3+), in the Institute of Biomedical Sciences of USP, where the samples will be manipulated with a higher security level making possible a better understanding of the etiology and epidemiology of this viruses and the improvement of the speed of the inquiry in the cases suspicious that present potential risk for the community. The main objectives are to standardize detention WNV for Real Teams PCR, to acquire a sensible and faster diagnosis and to make a selection of samples birds and equines of the tropical and subtropical regions of Brazil.
