Animal Disease Management and Epidemiology

During the year of 2010 the frequency of equines sero-reactants to the Infectious Anemia vírus (EIA) was investigated in 5,615 animals originated from 209 counties of three northeastern brazilian states: Paraíba, Rio Grande do Norte and Ceará. The serum samples were examined by an agar gel immunodiffusion test (AGID) produced with p26 antigen. Of the 5,615 animals examined 151 (2.69%) were seropositive to EIA. The proportion of seroreactant animals per state were: Paraíba (2.86%), Rio Grande do Norte (1.29%) and Ceará (3.10%). Paraíba presented an odds ratio of 2.64 (95% CI = 1.33-5.36; p = 0.004), while Ceará had an odds ratio of 2.87 (95% CI = 1.48-5.71; p = 0.001) both of them compared with Rio Grande do Norte. Paraíba had seropositive animals in all months of the year, with frequency ranging from 0.58% in July to 5.82% in June; in Rio Grande do Norte from March to May and from July to November ranging from 0% in January, February, June and December to 3.61% in May; and in Ceará in all months ranging from 1.10% in August to 7.29% in December.
