Mycoplasma pneumoniae is a common etiologic agent of lower respiratory tract infections in humans. However, it has been reported previously that the organism has occasionally been isolated from sites other than the oropharynx and respiratory tract. We report the isolation of 24 strains of M. pneumoniae from urogenital specimens obtained from 22 female patients. Most isolates were of cervical origin from patients attending several local gynecological clinics over a 2-year period. Strains were also isolated from the urethra of one of three healthy male sexual partners of female patients positive for the organism. Single serum specimens obtained from three female patients and three different male sexual partners showed antibody levels suggestive of either recent respiratory infection or genital tract colonization with M. pneumoniae. Although there is no apparent definitive explanation for the localized outbreak of the organism at these unusual sites, the possible transfer through sexual and/or orogenital contact remains the most likely mode of transmission. The occurrence of an organism with obvious pathogenicity for human epithelial tissue in the urogenital tract suggests such transfer could play a role in genital tract infection.
A combination of ferrous sulfate, sodium metabisulfite and sodium pyruvate, incorporated in solid medium, maintained the characteristic morphology, motility, and viability of six isolates of Campylobacterjejuni stored at room temperature and 4°C for up to 20 and 30 days, respectively, under normal atmospheric
The Gen-Probe rapid diagnostic system was compared with a culture method for the detection of Mycoplasma pneumoniae in clinical specimens. Of 116 clinical specimens, 103 (88.8%) yielded identical results. The relative sensitivity and specificity of the probe were both 89%. Rapid turnaround time and its sensitivity and specificity indicate that the probe test is a practical method for the rapid diagnosis of M. pneumoniae infections.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
