Summary

Forty-five strains of staphylococci and 6 strains of micrococci isolated from pasteurized ewes' milk cheeses (Manchego and Burgos varieties) were identified to species level. Three strains of staphylococci were identified as Staphylococcus aureus. Amongst the 42 coagulase-negative staphylococci, 8 were novobiocin-sensitive and 34 novobiocin-resistant. The novobiocin-sensitive species found were Staph. auricularis (5 strains), Staph. caseolyticus (2 strains) and Staph. epidermidis (1 strain). Novobiocin-resistant strains were identified as Staph. gallinarum (5 strains), Staph. xylosus (4), Staph. saprophyticus (9), Staph. cohnii (6), Staph. sciuri (1) and Staph. lentus (3). The other 6 isolates could not be identified. Only 3 strains of micrococci were identified (Micrococcus kristinae, M. varians and M. sedentarius). The possible origin of the isolates is discussed.
