Antibiotic resistance of coagulase-negative staphylococci isolated from artisanal Naples-type salami

In the present paper 42 isolates from Italian salami were specified as Stap hylococcusxylosus (30), Staph, capitis (1), Staph, saprophyticns (1), Staph . hominis (1), Staph. simulans (1), Staph. cohnii(1) and as Staph. spp. (7) . These strains were coagulase-negative and were examined for resistance/se nsitivity against 25 antibiotics including beta-lactams (7), macrolides (3) , amynoglicosides (5), glycopeptides, lincosamides (4) and novobiocin, fusi dic acid, chloramphenicol, rifampicin, tetracycline, minocycline, More than 64% of the strains were resistant to lincomycin, penicillin G, amoxicillin , fusidic acid and novobiocin. All the strains were multiresistant and disp layed at least three resistances. Over 75% had a multiple antibiotic resist ance (MAR) index between 0.2 and 0.5.
