The First Identification and Antibiogram of Clostridium perfringens Type C Isolated from Soil and The Feces of Dead Foals in South Korea

Abstract

Clostridium (C.) perfringens was isolated from 25 (11.1%) of 225 sampled horses and from 16 (35.56%) of 45 farms. All of the samples were negative for cpe, etx, itx, NetF genes and cpa gene were detected in 100% (25 of 25) of the samples that were positive for C. perfringens. cpb and cpb2 were detected in 40.0% (10 of 25) and 60.0% (15 of 25) of the samples that were positive for C. perfringens, respectively. Of the 25 C. perfringens isolates, 15 (60%) were type A and 10 (40%) were type C. Type C was observed on all the farms where the foals’ deaths occurred. None of the isolates were positive for type B, type D, or type E. The MIC Evaluator strips antimicrobial susceptibility test showed meropenem (96%), ampicillin (92%), amoxicillin/clavulanic acid (84%), and tetracycline (8%) sensitivity.
