Specific Protein Differences Among Strains of Ureaplasma urealyticum as Determined by Two-Dimensional Gel Electrophoresis and a Sensitive Silver Stain

Abstract: The proteins of nine strains of Ureaplasrna urealyticum, representing serovars I through IX, were analyzed by using two-dimensional gel electrophoresis and a sensitive silver staining procedure. The electrophoretic patterns of the nine strains tested could be divided into two distinct major groups, one group consisting of serovars 11, IV, V, VII, VIII, and IX (group A) and one group consisting of serovars I, 111, and VI (group B).Ureaplasma urealyticum strains are a serologically heterogeneous group of organis… Show more

“…One involved types 1 to 9, and the other involved types 1 to 9, 11, 12, and 14 (83,131). Although the serovars could be divided into the two genetic clusters (see below), only one serovar-unique protein was found and this was in serovar 9 (131). All other polypeptides were common to all serovars, limited to one of the two genetic clusters, or found in two or more serovars which were not always of the same group.…”

“…The following six species have been recognized in the genus Ureaplasma: Ureaplasma urealyticum, isolated from humans; Ureaplasma diversum, isolated from bovines; Ureaplasma gallorale, isolated from birds; Ureaplasma felinum and Ureaplasma cati, isolated from cats; and UreapZasma canigenitalium, isolated from dogs. The accumulated data suggest that the human species U. urealyticum consists of two different clusters, the T960 and parvo biovars, which can be distinguished on the basis of the results of polyacrylamide gel electrophoresis of cell proteins (12,20), DNA-DNA homology data (1), restriction endonuclease cleavage patterns (13), restriction fragment length polymorphism data (4), manganese susceptibility data (14), and DNA modification system data (2). The genome sizes of U. urealyticum strains have been estimated to be 760 to 1,170 kbp by pulsedfield gel electrophoresis (9).…”

“…The serovar-specific antigens appear to be on or in the surface membrane and they may be either lipid or proteinaceous [20]. Twodimensional gel electrophoresis has shown conflicting results with serovar-specific proteins, biovar-specific proteins and proteins common to all serovars [21].…”
