Abstract
Salmonella (2273) strains received from veterinary laboratories in the Federal Republic of Germany including Berlin (West) in 1972 were examined for their resistance against tetracyclines, ampicillin, chloramphenicol, kanamycin, nitrofurazone and furazolidone. Of the strains studied, 13.3% were resistant to 1 or more of these antibacterial substances. The proportion of resistant strains was 37.5% for Salmonella typhimurium (excluding var. copenhagen), 3.1% for S. typhimurium var. copenhagen and 57% for S. panama. Of the resistant strains, 79.8% belonged to these types. From 303 resistant strains found, resistance determinants were present in 87.4% to tetracyclines, 37.2% to ampicillin, 15.8% to chloramphenicol, 4.6% to kanamycin, 0.9% to furazolidone and 1.3% to nitrofurazone. Sixteen combinations of resistance determinants occurred. Of the strains, 95% transmitted resistance to Escherichia coli K-12. A transmission of resistance determinants to furazolidone and nitrofurazone could not be demonstrated. Resistance patterns differed considerably from 1 serotype to another.
