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

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 , genes and were detected in 100% (25 of 25) of the samples that were positive for . and were detected in 40.0% (10 of 25) and 60.0% (15 of 25) of the samples that were positive for , respectively. Of the 25 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.
