摘要：
Exoproteinase production was demonstrated in 64 clinical isolates ofS. marcescens. A significant relationship was found between the site of origin (autopsy material, hemocultures, various other sources), proteinase activity, and LD50 of the analyzed isolates. The number of exoproteinases varied during a 14-h incubation in batch cultures; the most frequently found was a 57.5-kDa proteinase which was observed in all analyzed strains. The exoproteinase production was shown to be related to strain virulence.
