万古霉素常用于治疗革兰氏阳性球菌感染,乳酸杆菌C可被误认是革兰氏阳性球菌,此菌所致感染尚未见确诊的病例报道,本文报告1例。男,49岁。因棕榈树碎片刺入右手拇指,致包裹性脓肿。脓肿行切开引流,并静脉给于先锋霉素Ⅰ,病人康复。脓液经革兰氏染色发现杆状或球杆状细菌,成对或链状排列,并有大量中性粒细胞。经细菌培养,证明为乳酸杆菌C。将细菌在35℃孵育24小时,然后以10~5cfu/ml用Mueller-Hinton琼脂稀释,测该菌对15种药物(mg/L)的药物敏感性。结果:对万古霉素(>256)、青霉素(1)、氨苄青霉素(0.5)、噻吩甲氧头孢菌素(32)、
Vancomycin commonly used in the treatment of Gram-positive cocci infection, Lactobacillus C can be mistaken for gram-positive cocci, the bacteria caused by infection has not been confirmed cases, this article reports 1 case. Male, 49 years old. Pricked into the palm of his right thumb because of palm debris, resulting in wrapped abscess. Abscess incision and drainage, and intravenous to Pioneer ADM Ⅰ, the patient recovered. Pus Gram stain found rod-shaped or rod-shaped bacteria, arranged in pairs or chains, and a large number of neutrophils. Bacterial culture proved to be Lactobacillus C. The bacteria were incubated at 35 ° C for 24 hours and then diluted with Mueller-Hinton agar at 10-5 cfu / ml to determine the drug’s susceptibility to 15 drugs (mg / L). Results: The effects of vancomycin (> 256), penicillin (1), ampicillin (0.5), thiophene methoxy cephalosporin (32)
