Distribution of thermophilic Campylobacters in animals and transfer of drug resistance factor of isolates to related bacteria I. Distribution and drug resistance of thermophilic Campylobacters isolated from animals

동물(動物)에서의 thermophilic Campylobacter의 분포(分布) 및 분리세균(分離細菌)의 약제내성(藥劑耐性) 전달(傳達)에 관(關)한 연구(硏究) I. 동물(動物)에서 thermophilic Campylobacter의 분포(分布) 및 분리세균(分離細菌)의 약제(藥劑)에 대한 내성(耐性)

To investigate the epidemiological trait of intestinal diseases of animals caused by thermophilic Campylobacter spp., isolation of etiological agent was carried out. Isolated Campylobacter spp. were biotyped, serotyped and the susceptibility of the isolates to antimicrobial agents were examined. Th results were as follows. 1. Isolation rates of Campylobacter spp. from 649 fecal materials of 208 cattle, 300 pigs and 141 chickens were 25.5%, 23.7% and 38.3%, respectively. 2. The majority of the 130 isolates of C jejuni was classified as biotype I(50.6%) and biotype II (34.6%). Most of the 46 isolates of C coli were biotype I (71.7%). 3. Isolated C jejuni strains showed 14 different serotype, and serotype 4, 26, 36 were most frequent. Isolated C coli strains showed 5 different serotype and serotype 31 and 21 were relatively common. 4. Isolated Campylobacter spp. were highly susceptible to nalidixic acid, amikacin, gentamicin, colistin and chlorampehnocol.
