Soroprevalência de anticorpos e padronização do teste ELISA sanduíche indireto para 19 tipos de arbovírus em herbívoros domésticos. 2010. 185 f.

Programa de Pós-Graduação em Biologia de Agentes Infecciosos e Parasitários.https://repositorio.ufpa.br/handle/2011/4760The brazilian Amazon region maintains the largest variety of arboviruses and the state of Pará is responsible for 26% of this territory, so the major goal of this work was to determine the prevalence and distribution of HI antibodies to 19 domestic arbovirus in domestic herbivores in the state of Pará and to standardize an indirect sandwich IgG ELISA test to serum samples of equines, cattle, buffaloes and sheep. In all species studied and throughout the State of Pará a large prevalence of HI antibodies to all arbovirus analyzed was observed and SLEV, ILHV, EEEV, MAGV and WEEV, showed higher prevalence, where the SLEV was the most prevalent. Regarding the virus families HI antibodies to MAGV was the most prevalent Bunyaviridae in all species, the most prevalent Flaviviridae was SLEV in all species and in the family Togaviridae the EEEV was more prevalent in horses. In order to analyze the prevalence of HI antibodies by animal species was observed that horses did not show significant differences compared to buffaloes, however, showed significant difference compared to cattle and sheep; there was not observed significant difference between the ruminant species. Using sandwich indirect IgG ELISA a large number of crossed reactions were found. This enzymatic test can be used to detect IgG antibodies among families of arboviruses studied.porAcesso AbertoArbovírusHerbívoros domésticosPrevalênciaEnsaio de imunoadsorção enzimáticaBiogeografiaSoro prevalência de anticorpos IHPará - EstadoAmazônia brasileiraTeseCNPQ::CIENCIAS BIOLOGICAS::MICROBIOLOGIA::BIOLOGIA E FISIOLOGIA DOS MICROORGANISMOS::VIROLOGIA
