title: [The capacity of Ureaplasma urealyticum, Mycoplasma hominis and seven other Mycoplasma species for hemadsorption, sperm adsorption, hemolysis and peroxide formation].
abstract: Searching for potential virulence markers of Ureaplasma (U.) urealyticum and Mycoplasma (M.) hominis, simple laboratory methods were used to detect strain specific properties. Haemadsorption, sperm adsorption, haemolysis, and peroxide formation were tested on clinical isolates and type strains of U. urealyticum and M. hominis in comparison to reference strains of seven other Mycoplasma species. In contrast to M. bovis, M. gallisepticum and M. pulmonis, all strains of M. hominis and U. urealyticum failed to adsorb human spermatozoa and erythrocytes from five vertebrate species to their colonies. Unexpectedly, colonies of M. arthritidis PG 6 adsorbed both human erythrocytes and spermatozoa. Using various methods, the known haemolytic and peroxide activities of the reference strains could be confirmed. None of the U. urealyticum strains tested demonstrated lysis of human or ovine erythrocytes or peroxide production. On the other hand, 76 of 108 isolates of M. hominis showed an alpha'- or beta-haemolysis of different degree. However, this phenomenon could not be reproduced in all cases and it was not attributable to the activity of a peroxide. None of the methods used in this study were found to be suitable for detection of possible virulence factors of U. urealyticum or M. hominis.
