Linfadenite caseosa em ovinos e caprinos criados nas micro-regiões de Piancó e Itaporanga - PB: inquérito e fatores de risco associados à doença.

Abstract

The risk factors associated to caseous lymphadenitis were identified in sheep and goats from Piancó and Itaporanga microregions, Paraíba state, Brazil. The work was conducted in eight municipalities from Piancó and Itaporanga microregions, Paraíba state, Brazil. It were examined 640 animals: 320 sheep and 320 goats from 32 herds. The importance of eight variables in the maintenance and spread of the disease in the herds was verified in the univariate analysis. Afterwards, these variables were offered to multiple logistic regression. Clinically, the frequency of abscesses and/or abscesses scars was 4.5 % in goats and 3.1% in sheep. It was verified that 31.3% (10/32) of the herds presented no evidence of the disease. In the final model, it was observed that animals from herds where the owners let the abscesses break naturally presented larger odds of caseous lymphadenitis (OR = 8.19; 95% C.I. = 1.75 – 38.25). The results obtained in the present study suggest the adoption of the following prophylactic actions: precocious opening and drainage of superficial abscesses and adequate destination of purulent content.
