RESUMO

The aim of this study was to determine the prevalence and to identify the risk factors associated with Leptospira spp. infection in technified pig farms in the state of Alagoas, Brazil. To compose sample for the prevalence study, 342 pigs were used (312 sows and 30 boars) proceeding from seven swine farms distributed in five districts of the state of Alagoas, Brazil. The infection's serological diagnosis was performed by microscopic agglutination test. The risk factors analysis was performed using research questionnaires consisting of objective questions related to the breeder, the general characteristics of the property, and the productive, reproductive and sanitary management. Prevalence of 16.1% (55/342) of pigs seropositive was obtained. The associated risk factors were not performing quarantine (P = 0.003, OR = 5.43, CI = 1.79-16.41) and the use of artificial insemination (P = 0.023, OR = 3.38, CI = 1.18-9.66). A significant association of sow infection with the increased number of stillborn and mummified foetuses was found, as well as with the increased frequency of oestrus recurrence and the increased weaning-to-oestrus interval of seropositive sows. One might state that Leptospira spp. infection is disseminated in technified pig farms in the State of Alagoas, favouring reproductive failures and the impairment of zootechnical performance in these properties. The risk factors identified in this study are facilitators in the infecting agent dissemination and should be adjusted to control the disease in the herds studied.

RESUMO

Skin scrapings of three sloths Bradypus variegatus from the State of Pernambuco, Brazil, were analysed after lactophenol clarification. The mites Sarcoptes scabiei De Geer, 1778 and Lobalges trouessarti Fonseca, 1954 were identified. For the first time, S. scabiei and L. trouessarti are recorded as mange agents in B. variegatus
