Avaliação dos fatores de risco e prevalência da leptospirose em caprinos em municípios do Alto Médio Gurguéia do Estado do Piauí / Evaluation of risk factors and prevalence of leptospirosis in goats in minicipalities of Microrregion of the Upper-middle Gurguéia the State of Piaui

ABSTRACT

The objective of this study was to evaluate the risk factors and to calculate the prevalence ofLeptospirosis in goats in municipalities of the Upper Gurguéia micro region of the State of Piauí. A total of 143goat samples were collected from four (4) municipalities of the micro-region. Applied an epidemiologicalquestionnaire with possible risk factors. The diagnosis was made by the microscopic sero-agglutination (SAM)technique against 22 pathogenic serovars. The reagents were determined serovar appears when 50% or moreagglutination reaction on the cutting point titer of 1 100. The overall prevalence was 9.09%. SerumIcterohaemorrhagiae were found in 5.59%, Grippotyphosa in 1.4%, Icterohaemorragiae + Pomona (0.7%),Icterohaemorrhagiae + Canicola (0.7%) and Icterohaemorrhagiae + Autumnalis (0.7%). It is concluded that inthe studied region it has a high prevalence for leptospirosis and that there are no measures of controls tocontain the risk factors.
