幼兒의 病原性 大腸菌症에 관한 硏究 2. 설사병幼兒에서 分離한 大腸菌의 R. Plasmid

Studies on Enteric Colibacillosis in Infants 2. Antimicrobial Drug Resistance and R. Plasmids of Escherichia coli Isolated from Infants with Diarrhea

The antimicrobial drug resistance of 402 strains of Escherichia coli isolated from infants with diarrhea were investigated by the use of agar plate dilution method and R plasmids in resistant strains was also tested. A total of 402 Escherichia coli strains were isolated from 106 diarrheal infants and tested for drug resistance and conjugative R plasmids. Among the 402 strains of E. coli isolated, 83. 3% were found to be resistant to one or more drugs against 8 drugs in generally used such as tetracycline(TC), neomycin (NM), chloramphenicol (CP), ampicillin (APC), gentamycin (GM), streptomycin (SM), kanamycin (KM) and nalidixic acid (NA).
