Comparison of Smooth-Rough Form Variation and Antibiotic Susceptibility of Escherichia coli and Clostridium perfringens Isolates from Chickens, Pigs and Cattle

Abstract

Acriflavine 시험법을 이용해서 수종의 화학물질을 첨가한 배지에 대장균과 Clostridium perfringens을 배양하여 변이를 유도한 후, S-R 변이와 변이 후의 항생제에 대한 감수성을 조사한 결과, 화학물질에 대한 S-R변이의 경우, 대장균은 mercuric chloride, cysteine, caffeine, glucose, nicotine 등의 순으로 나타났고, C. perfringens는 mercuric chloride, nicotine, caffeine, cystein, glucose 등의 순으로 나타났으며 양자 공히 mercuric chloride가 가장 감수성이 높았다. 항생제에 대한 S-R 변이 후의 감수성은 대장균과 C. perfingens가 공히 S-R변이 후에는 감수성이 일반적으로 저하되는 경향이었다.
