What is Prevalence and multilocus sequence typing of Clostridium perfringens isolated from 4 duck farms in Shandong province, China about?
__Clostridium perfringens__ is an important zoonotic microorganism. The present study was undertaken to investigate prevalence, serotype distribution, antibiotic resistance, and genetic diversity of __C. perfringens__ isolates from 4 duck farms in Shandong, China. In total, 424 samples of cloacal swabs and environment were collected from 3 commercial meat-type duck farms in Tai'an, Liaocheng, and Weifang and one breeder duck farm in Liaocheng between December 2018 and June 2019, of which, 207 (48.82%) samples were determined to be positive for __C. perfringens__; a total of 402 isolates of __C. perfringens__ were recovered, all of which were identified as type A; 30.85% of the isolates were positive for __cpb2__ gene; and __cpe__ gene was found in 0.5% of the isolates. Antimicrobial susceptibility testing revealed that some of the isolates exhibited high antibiotic resistance, and 39.14% of the isolates were resistant to at least 5 classes of commonly used antibiotics. Multilocus sequence typing analysis showed that 85 representative isolates encompassed 54 different sequences types (**STs**), clustered in 5 clonal complexes (**CCs**) and 40 singletons. ST3, the most common ST in 5
