Abstract
Salmonella strains (2894) received from veterinary laboratories in the Federal Republic of Germany including Berlin (West) in 1973 were examined for their resistance against tetracyclines, ampicillin, chloramphenicol, kanamycin, nitrofurazone and furazolidone. Of the strains studied, 24.4% were resistant to 1 or more of these antibacterial substances. The proportion of resistant strains was 63.9% for Salmonella typhimurium (excluding var. copenhagen), 6.5% for S. typhimurium var. copenhagen and 51% for S. panama. Of the resistant strains, 81.3% belonged to these types. From 708 resistant strains found, resistance determinants were present in 92.9% to tetracyclines, 27.9% to ampicillin, 22.0% to chloramphenicol, 13.6% to kanamycin, 1.4% to furazolidone and 1.7% to nitrofurazone. Twenty combinations of resistance determinants occurred. Of the strains, 90.9% transmitted resistance to Escherichia coli K-12. A transmission of resistance determinants to furazolidone and nitrofurazone could not be demonstrated. As in the preceding years, there was a clear difference of resistance patterns from 1 serotype to another.
