Genotyping and antimicrobial susceptibility of Clostridium perfringens isolated from Tinamidae, Cracidae and Ramphastidae species in Brazil

Genotipagem e sensibilidade antimicrobiana de estirpes de Clostridium perfringens isolados de espécies de Tinamidae, Cracidae e Ramphastidae no Brasil

Abstracts

The aim of this study was to isolate, genotype and evaluate the antimicrobial susceptibility of Clostridium perfringens found in species Tinamidae, Cracidae and Ramphastidae in Brazil. C. perfringens was isolated in 13 (5%) out of 260 swab samples and five (8.3%) out of 60 stool samples. All strains were classified as C. perfringens type A, and nine (50%) were positive for the beta-2 toxin-encoding gene. No strains were positive for the necrotic enteritis toxin B-like (NetB)-encoding gene. All isolates were susceptible to penicillin, metronidazole and vancomycin, whereas four (22.2%), five (27.8%) and 13 (72.2%) strains were considered resistant to erythromycin, oxytetracycline and lincomycin, respectively.
