Mycoplasmas cause several diseases in cattle as pneumonia in calves and mastitis in cows and also reproductive disorders, abortions, arthritis and conjunctivitis. The difficulty of culturing mycoplasmas in vitro is a major obstacle to research and laboratory diagnosis of these fastidious organisms. A total of 120 preputial swabs, 70 vaginal swabs and 65 milk samples were collected from cattle a...

Ureaplasma urealyticum organisms (ureaplasmas) were isolated from the urethra and epididymal aspirate of a man aged 24 who had acute right sided epididymitis. No other microorganisms were detected, and he had no chlamydial antibody response. A fourfold antibody response to the epididymal ureaplasma isolate was detected by two methods, however, and the patient responded clinically to doxycycline...

OBJECTIVE The genital mycoplasmas (Mycoplasma hominis and Ureaplasma urealyticum) and Chlamydia trachomatis have been implicated as possible etiologic factors in infertility. Their role in patients with infertility needs to be further defined. METHODS Seventy-nine infertile patients underwent laparoscopy with cultures obtained for aerobic and anaerobic bacteria, Chlamydia, Mycoplasma, and Ure...

In this study, the phylogenetic relationships between the two biovars and 14 serovars of Ureaplasma urealyticum were studied using the sequences of four different genes or genetic regions, namely: 16S rRNA genes; 16S-23S rRNA gene spacer regions; urease gene subunits ureA, ureB, partial ureC and adjoining regions upstream of ureA, ureA-ureB spacer and ureB-ureC spacer; the 5'-ends of the multip...

BACKGROUND Intra-amniotic infection has long been recognized as the leading cause of preterm delivery. Microbial culture is the gold standard for the detection of intra-amniotic infection, but several days are required, and many bacterial species in the amniotic fluid are difficult to cultivate. METHODS We developed a novel nested-PCR-based assay for detecting Mycoplasma, Ureaplasma, other ba...

Ureaplasma urealyticum organisms (ureaplasmas) were isolated in large numbers (up to 10(8) colour changing units (ccu)/ml) over a period of four years from the urethra of a man with hypogammaglobulinaemia and non-gonococcal urethritis. Elimination of Mycoplasma hominis by antibiotic treatment early in the course of the urethritis did not diminish the severity of his condition, which indicated t...

BACKGROUND The aim of this study was to contribute to the insight of the role of the infectious agent in ethiopathogenesis of the Reiter's syndrome development, which could directly influence the choice of treatment of these patients. METHODS Eighteen patients with urogenital form of the Reiter's syndrome and 16 controls (6 with rheumatoid arthritis and 10 with pigmented villonodular synoviti...

Objectives: The symbiosis of Trichomonas vaginalis and Mycoplasma hominis is the first described association between two obligate human parasites. Trichomonas is the niche and the vector for the transmission of M. hominis infection. This clinically significant symbiosis may affect T. vaginalis virulence and susceptibility to treatment. The aims of this study were to investigate the intracellula...
