Ocorrência de patógenos de interesse em saúde única em canídeos silvestres de cativeiro e de vida livre na região nordeste do Brasil

Abstract

The aim of this study was to investigate the occurrence of pathogens of interest in One Health in captive and free-range wild canids from northeastern Brazil. Biological samples (stool, fur and blood) were collected from 25 crab-eating foxes (Cerdocyon thous) from four states: Alagoas, Bahia, Paraíba, Pernambuco. From these samples was possible to obtain the first Toxoplasma gondii isolate (genotype #13) in crab-eating fox; Ctenocephalides canis and felis, Sarcoptes scabiei, Malassezia pachidermatis in animals from Paraíba and also one co-infection case by Microsporum gypseum; isolation of Clostridium perfringens – type A in five stool samples (one of them positive to beta-2 toxin) and Clostridium difficile in two stool samples. In molecular (PCR) and serological analysis (MAT for T. gondii, NAT for N. caninum, ELISA for L. chagasi and MAT for Leptospira spp) were observed frequencies of anti-T. gondii antibodies of 50% and 29.41% in captive and free-range wild canids, respectively, frequencies of anti-N. caninum antibodies of 62.50% and 23.52% in free-range and captive wild canids, respectively, frequency of anti-L. chagasi antibodies of 4.0% in captive wild canids. There were no serum samples positive for Leptospira, as well as absence of positive PCR for the pathogens analyzed in the blood. The results of this study demonstrate the circulation of pathogens with an impact on One Health. Studies involving wild animals and infectious diseases should be performed to provide data on the epidemiology of these diseases and to guide surveillance and control measures.
