ABSTRACT

We investigated the presence of antibiotic-resistances and others important virulence factors in coagulase negative and positive staphylococci, isolated from several sources (food, environmental and clinical). Thirty-four staphylococci were isolated and identified (28 coagulase-positive were identified as Staphylococcus aureus, 6 remaining Coagulase Negative Staphylococci were identified as 3 S. epidermidis, 2 S. warneri, 1 S. hycus). All the strains were analyzed both with phenotypic and genotypic assays in order to evaluate the virulence factors and the susceptibility against antibiotics and to correlate them to the sources of isolation. Results showed that isn't a direct correlation between features researched and isolation, and the different virulence factors are as widespread as antibiotic-resistance. The isolation from food of a strain of Staphylococcus aureus with a high methicillin resistance was very interesting. 15 of the 34 strains were found to possess multi-drug resistance and in 7 cases with Minimum Inhibitory Concentration(MIC) really very high; also in this case there is no distinction between the coagulase-positive and coagulase-negative staphylococci and their origin of isolation.
