Antibiogram typing of methicillin-resistant Staphylococcus aureus: a comparison with phage typing, biotyping and API Staph.
68 strains of methicillin- and gentamicin-resistant Staphylococcus aureus (MRSA) have been characterized by four different methods. First, by their production of lecithinase, lipase, pigment and sheep haemolysin. Second, by API Staph code. Third, by their sensitivity to 9 antibiotics. Fourth, by phage typing using the International Set and Supplementary phages. The third method was the most discriminatory. The combination of the first three techniques provides a highly effective, cheap and simple system to type MRSA. 80 separate MRSA strains from 26 countries were found to belong to a wide variety of phage types. Most were of group III. The most commonly found types were 85 (6 strains), 84 (4 strains) and 47 (3 strains).
