Molecular characterization of trimethoprim resistance in salmonellas isolated in Sicily, 1985-1988.

European journal of epidemiology - 1 Feb 1995

Abstract excerpt

The occurrence of trimethoprim (Tp) resistance in salmonellas isolated from humans and water samples in Sicily between 1985 and 1988 has been investigated and the Tp resistance mechanisms have been further characterized on the basis of hybridization with probes for the dihydrofolate reductase (DHFR) genes types I, II, IV and V. Of 765 strains examined, high level (> 1000 mg/l) resistance to Tp was identified in...
