||129 strains of Micrococcaceae were isolated from food of animal origin (minced meat, cakes with confectioner's custard) on Baird-Parker medium. 120 were Staphylococcus and 9 Micrococcus, according to the ID 32 STAPH-System (1989). The results were analyzed using a computer program. 60% of these 120 Staphylococcus strains of animal origin were coagulase positive S. aureus (aurease+, Rapidec Staph technique). 46% were resistant to novobiocin (5 microg/ml), 13 to 44% were identified with negative discordant tests using this micromethod. 44% produced no acetoin, 35% had no urease and 15% no arginine dihydrolase. 48 Staphylococcus strains (40%) were identified as human coagulase negative Staphylococcus species (strains: 39; species: 9) or as animal species (strains: 4; species: 1). 5 were Staphylococcus sp S. epidermidis and S. warneri represented 63% of these Micrococcaceae with particular biochemical characteristics.
