Over a six year period, in the Clinic of Communicable Diseases of Cluj Napoca, 2301 patients with staphylococcal infections were admitted to the Clinic, representing 8% of the total number of patients admitted, and 3513 staphylococcal strains were isolated. A number of 43 of the 2301 patients died (1.8%), but staphylococcal infection was actually the cause of death in only 35 cases (1.5%) (septicemia, staphylococcal meningitis and pulmonary infections). Eight of the patients died from the basic disease (hepatitis, tetanus, paratyphoid C fever etc.). A number of 2246 Staphylococcus hemolyticus aureus, 80 non-hemolytic Staphylococcus aureus and 162 Staphylococcus albus strains were isolated; most of the strains were resistant to antibiotics in different proportions.
