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 routine cultures for this organism unless the urine is alkaline and struvite crystals, leukocytes, and erythrocytes are present.
解脲棒杆菌(以前称为棒杆菌D2群)被认为是碱性结痂性膀胱炎和尿路鸟粪石结石的病因。尽管预先选择了pH值为中性和碱性的尿液标本,并在选择性培养基上进行长时间培养,但在住院患者群体中很少观察到该菌的分离。除非尿液呈碱性且存在鸟粪石晶体、白细胞和红细胞,否则我们不建议对该菌进行常规培养。
