Drug resistance of organisms isolated from feces of laboratory mice and rats.
A total of 248 strains of EScherichia coli, 132 of Staphylococcus epidermidis, 137 of Streptococcus faecalis and 89 of STr. faecium were collected from feces of 40 mice and 36 rats of 8 colonies in 1978, and drug resistance were examined by an agar dieution method using 23 antibiotics. The results indicated a positive relation between use of antibiotics and appearance of multiple drug resistant organisms.
