| Actinobacillus actinomycetemcomitans is a clinically relevant periodontopathogenic Gram-negative coccobacillus that produces a leukotoxin of the RTX cytolysin family. In this study, we evaluated the leukotoxic activity of A. actinomycetemcomitans strains isolated from human and marmosets by Trypan blue exclusion and by the chemiluminescence assays. Among eight A. actinomycetemcomitans human strains studied, two (P2.17 and P8.12) were classified as high leukotoxin producers and among eight marmoset strains, one (M22.11) showed high leukotoxin production, as determined by Trypan blue exclusion assay. The reference strains ATCC 29523 and FDC Y4 respectively behaved like moderate and low producers. The chemiluminescence assay was used to evaluate the... |
