Use of selective media for isolating Corynebacterium urealyticum from urine specimens

Use of selective media for isolating Corynebacterium urealyticum from urine specimens.

Prevalence of Corynebacterium urealyticum in urine specimens collected at a university-affiliated medical center.

Corynebacterium urealyticum (formerly Corynebacterium group D2) has been implicated as a cause of alkaline-encrusted cystitis and urinary tract struvite calculi. Despite preselecting urine specimens with neutral and alkaline pHs and using prolonged incubation on a selective medium, isolation of this organism was rarely observed in a population of hospitalized patients. We do not recommend routi...

Laboratory proficiency test results on use of selective media for isolating Pseudomonas cepacia from simulated sputum specimens of patients with cystic fibrosis.

Pseudomonas cepacia colonization of or infection in patients with cystic fibrosis (CF) has been associated with increased morbidity and premature death. However, current data on national incidence may be biased because of interlaboratory differences in the methods of culturing sputa of patients with CF. We conducted three tests to evaluate the proficiency of microbiology laboratories at CF cent...

Unusual colonies of Ureaplasma urealyticum (T mycoplasmas) in primary agar cultures of certain urine specimens.

The existence of unusual colonies of Ureaplasma urealyticum (T mycoplasmas) in primary agar cultures of certain urine specimens is reported and their morphology is illustrated.

COMPARISON OF CULTURE WITH POLYMERASE CHAIN REACTION FOR DETECTION OF UREAPLASMA UREALYTICUM IN ENDOCERVICAL SPECIMENS

Background: Ureaplasma urealyticum is known as a sexually transmitted agent, causing mainly urethritis, pelvic int1ammatory disease, spontaneous abortion, pyelonephritis, infertility, stillbirth, low birth weight neonatal meningititis, and neonatal pneumonia. U. urealyticum infections not only jeopardize fertility but also pose a risk for infertility treatment and resulting pregnancies. Dia...
