[Incidence of staphylococcal serotypes in different hospitals (author's transl)]

A total of 409 Staphylococcus aureus strains were classified with 17 typing sera into 16 groups and 14 types. Strains with the formula a b+ c e and h+ i k l were most frequently met with. The majority of strains isolated from typical staphylococcal diseases contained antigens e', h+ and/or h++ whereas those associated with atypical infections showed antigens b++ and o most frequently. Classification by Oeding and Williams' scheme yielded a less wide variety of serological units: most strains fell into group 4; spontaneously agglutinating and group 1, 2 and 3 strains were next in order.
