| description | ABSTRACT: Clostridium perfringens (C. perfringens) is the etiological agent of necrotic enteritis and gangrenous dermatitis; 2 diseases that cause significant economic and welfare concerns to the broiler industry. Previously, Clostridium-related diseases were managed with the use of antimicrobial growth promoters fed to broilers that improved gut health and performance. The recent shift to no antibiotics ever (NAE) production has increased the incidence of Clostridium-related diseases. The objective of this study was to identify C. perfringens prevalence and toxinotypes in NAE farms. Samples of litter, feces, and cloacal swabs were collected from 4 NAE broiler farms in the summer of 2019, on d 28 and d 56 of one flock cycle. A total of 734 presumptive isolates were obtained from 192 samples collected in the study. Irrespective of the age of flock and sample type, all 192 samples contained at least one colony presumptively identified as C. perfringens on Perfringens agar plate with morphology as a single, round colony with opaque ring and black center. All isolates were further screened using PCR for confirmation, toxinotyping, and identification of virulence-associated genes. Only 9 isolates among the 734 presumptive isolates were confirmed as C. perfringens and all confirmed isolates were toxinotype A with variation in presence of netB, cpb2, and tpeL. More extensive studies are required to assess the prevalence and virulence of C. perfringens in NAE farms. |
