M. fermentans may induce respiratory and genitourinary tract infections. We investigated the presence of putative adhesins from strain P-140. A surface protein of 47 kDa, labeled SP47, isolated from M. fermentans P-140, seems to be involved in acterial adherence on HEp-2 cells;this study could allow helping understand the interaction between mycoplasmas and their hosts. Anti-SP47 antibodies inhibited the formation of bacterial clusters and adherence to cultured cells, quantified by ELISA. M. fermentans P-140 was more efficient at adhering to cultured HEp-2 cells than PG-18.展开更多
