SOROPREVALÊNCIA DE THEILERIA EQUI EM EQUINOS NA MICROREGIÃO DO AGRESTE PARAÍBANO

Abstract

Theileriosis are intra-erythrocyte infection widespread among domestic and wild animals caused by protozoa of the genus Theileria and transmitted by several species of ticks. This disease causes serious problems in the marketing of livestock tick-free zones for enzootic areas. The objective of this study was evaluate seroepidemiological data of Theileria equi in horses of urban and rural areas of six municipalities in the state of Paraíba. A total of 138 animals were sampled and tested using the indirect immunofluorescence test. Of all the animals studied, 85/138 (61.6%) were seropositive. There was no significant association between the presence of ticks, age or sex with seropositivity for T. equi (p> 0.05). Prevalence in the serological analysis of positive horses for T. equi who had hematocrit less than 32% was 68.9% and 66.38% of the horses had increased total plasma protein (> 7.9 g / dL). Therefore, attentive to the need to control ticks, monitoring the health of animals and preparation of active surveillance programs to prevent the spread of this parasite to susceptible animals.
