Drug resistance of some bacteria isolated from food samples in hospital environment (Rabat Avicenne Hospital).

Objective - We wanted to study the bacteria isolated from food samples in h ospital environment to determine their resistance to drugs. Results - The isolated strains were Escherichia coli from total and fecal c oliforms, Staphylococcus aureus, Salmonella Blockley, and Pseudomonas aerug inosa These strains were tested for their susceptibility to fifteen antibio tics widely used in human therapy. Most of the strains presented the same p rofile of resistance. a high level of resistance to oxytetracycline and to the combination sulfamethoxazole-trimethoprime, a variable response to beta -lactamines and chloramphenicol depending on the strains, a higher suscept ibility to imipenem, ciprofloxacin, gentamicin, amikacin, colistin, and van comycin. Comments - These results prove that drug resistance must be monitored. (C) 2000 Editions scientifiques et medicales Elsevier SAS.
