| Abstract: | "Hemolysin production, clumping (pheromone) response, transferability of the hemolytic trait, and drug resistance were examined in 97 clinical isolates of Enterococcus (Streptococcus) faecalis. The isolates were derived from various sources (i.e., urine, pus, vagina, sputum, bile, and blood), and approximately 60% were found to be hemolytic. About 85% of the hemolytic strains exhibited a clumping response, compared with about 49% of the nonhemolytic strains. Over 50% of the hemolytic strains carried transferable hemolysin determinants, and in no case were drug resistance genes linked. The hemolytic strains exhibited multiple drug resistance more frequently than did the nonhemolytic strains. In contrast to the high frequency of hemolysin producers among parenteral isolates, strains derived from fecal specimens of healthy individuals exhibited a low (17%) incidence of hemolysin production" |
