Mj. Alfa et al., HAEMOPHILUS-DUCREYI HEMOLYSIN ACTS AS A CONTACT CYTOTOXIN AND DAMAGESHUMAN FORESKIN FIBROBLASTS IN CELL-CULTURE, Infection and immunity, 64(6), 1996, pp. 2349-2352
Haemophilus ducreyi, which causes the sexually transmitted disease cha
ncroid, produces several factors that damage human cells. We used isog
enic mutants of H. ducreyi 35000 to demonstrate that the hemolytic act
ivity and the cytotoxic effect of H. ducreyi on human foreskin fibrobl
asts are due to the same toxin.
