title: Occurrence of coagulase serotype among Staphylococcus aureus strains isolated from healthy individuals--special reference to correlation with size of protein-A gene--.
abstract: One-hundred-and-nineteen strains of Staphylococcus aureus isolated from healthy individuals for 3 years between 1991 and 1993 were subjected to an investigation on the producibility of proteins including protein A, coagulase, enterotoxins and toxic-shock syndrome toxin-1. Especially, protein A was the center of our interest. Among these strains, 69, 43, 3 and 1 strains were found to have the protein-A gene containing 5, 4, 3 and 2 IgG-binding domains, respectively. On the other hand, only one strain was devoid of the protein-A gene. There were some differences in the profile of the coagulase serotype between the group with 4 IgG-binding domains and that with 5 IgG-binding domains. Differences in the profile of toxin production were also observed between the two groups.
