Fifty-four strains of Peptostreptococcus magnus (11 were recovered from abdominal infections, 18 were from nonpuerperal breast abscesses, and 21 were from diabetic foot infections; the type strain and three other strains were from the American Type Culture Collection, Rockville, Md.) and the type strain of Peptostreptococcus micros were tested for their ability to produce various enzymes, including catalase, hippurate hydrolase, serine dehydratase, threonine dehydratase, collagenase, gelatinase, alkaline phosphatase, and esterase C4. The data were analyzed by cluster analysis. The results showed that all but one strain could be assigned to either of two distinct, valid clusters. The first cluster of 11 strains was composed of strains that were relatively inactive, having produced one or two of the eight strain-dependent enzymes. The second was a large cluster of strains (n = 43) that were considerably more active, all having produced at least three enzymes; the vast majority of strains (89%) produced four or more enzymes. The unclustered strain produced one enzyme that was different from that produced by the strains in the first cluster. The chi 2 test of homogeneity applied to the clustering solution indicated that greater enzyme activity was significantly associated with the site of infection (P less than 0.001). The more enzymatically active P. magnus strains were recovered significantly more often from nonpuerperal breast abscesses and diabetic foot infections than they were from abdominal infections. These results may provide insight into the nature of certain polymicrobial soft tissue infections and suggest that (i) P. magnus may participate more in nonpuerperal breast and diabetic foot infections than in abdominal infections and that (ii) peptostreptococcal production of proteolytic enzymes may have an important adjunctive effect on the pathogenesis of certain soft tissue infections.
