M. Ryan et Pr. Murray, PREVALENCE OF CORYNEBACTERIUM-UREALYTICUM IN URINE SPECIMENS COLLECTED AT A UNIVERSITY-AFFILIATED MEDICAL-CENTER, Journal of clinical microbiology, 32(5), 1994, pp. 1395-1396
Corynebacterium urealyticum (formerly Corynebacterium group D2) has be
en implicated as a cause of alkaline-encrusted cystitis and urinary tr
act struvite calculi. Despite preselecting urine specimens with neutra
l and alkaline pHs and using prolonged incubation on a selective mediu
m, isolation of this organism was rarely observed in a population of h
ospitalized patients. We do not recommend routine cultures for this or
ganism unless the urine is alkaline and struvite crystals, leukocytes,
and erythrocytes are present.
