Abstract
The effects of pH, temperature, proportion of Staphylococcus aureus in the inoculum, various strains of effector organism, and various strains of S. aureus were examined for their influence on interactions between staphylococci and effector organisms in associative culture. In general, small changes in pH had little effect upon either growth of S. aureus or production of enterotoxin in associative culture. Inhibition of growth of S. aureus caused by effector organisms was much greater at 25 than at 30 C. Proportion of S. aureus in the inoculum greatly affected both growth of the staphylococci and production of enterotoxin. Only slight differences were found between strains of either effector organism or S. aureus which affected the interactions in associative culture.
