spp. are non-spore-forming Gram-positive anaerobes that are indigenous to the human gastrointestinal tract and vagina. They are believed to be non-pathogenic organisms for humans and thus are widely used as probiotics. An 83-year-old woman taking cephalexin for 4 days was diagnosed with obstructive pyelonephritis. Y-branched Gram-positive rods were found in both anaerobic and aerobic blood culture bottles, and in an anaerobic urine culture. was finally identified. Ceftriaxone and metronidazole were administered to the patient, and she was discharged after intermittent catheterization for dysuria. Urinary tract infection caused by spp. is believed to be rare, but it can develop in patients with underlying urological conditions. Recognition of the characteristic morphology and conducting anaerobic urine culture may help in identifying more cases of urinary tract infections.
[物种名称]是无芽孢形成的革兰氏阳性厌氧菌，是人类胃肠道和阴道的固有菌。它们被认为对人类无致病性，因此被广泛用作益生菌。一名83岁的女性服用头孢氨苄4天后被诊断为梗阻性肾盂肾炎。在厌氧和需氧血培养瓶以及厌氧尿培养物中均发现了Y形分支的革兰氏阳性杆菌。最终得以鉴定。患者接受了头孢曲松和甲硝唑治疗，因排尿困难进行间歇性导尿后出院。[物种名称]引起的尿路感染被认为很罕见，但在有潜在泌尿系统疾病的患者中可能会发生。认识其特征性形态并进行厌氧尿培养可能有助于识别更多[物种名称]引起的尿路感染病例。
