Leptotrichia species are fastidious anaerobic, fusiform, pencil-shaped Gram-negative bacilli that reside in microbiota of humans. Leptotrichia species have increasingly been recognized as an opportunistic pathogen in humans, mainly in the immunocompromised patient. Anaerobic organisms have rarely been isolated from blood cultures of pediatric patients. In our study, we isolated Leptotrichia trevisanii from central venous catheter culture of a five-year-old male patient. It was identified with both matrix-assisted laser desorption ionization time-of-flight mass spectrometry and confirmed via 16S rRNA gene sequencing. The early recognition of anaerobic bacteremia and administration of appropriate antimicrobial and play an important role preventing mortality and morbidity in children. In our study we report a rarely diagnosed case of L. trevisanii bacteremia in a pediatric patient.

发热性中性粒细胞减少症儿科特雷维萨细毛菌引起菌血症一例并文献复习


纤毛菌属是一种挑剔的厌氧、梭形、铅笔形革兰氏阴性杆菌，存在于人类微生物群中。纤毛菌物种越来越多地被认为是人类的机会性病原体，主要是在免疫功能低下的患者中。很少从儿科患者的血培养物中分离出厌氧微生物。在我们的研究中，我们从一名五岁男性患者的中心静脉导管培养物中分离出特雷维萨细毛菌。它通过基质辅助激光解吸电离飞行时间质谱进行鉴定，并通过 16S rRNA 基因测序进行确认。早期识别厌氧菌血症并给予适当的抗菌药物对于预防儿童死亡和发病发挥着重要作用。在我们的研究中，我们报告了一名罕见的儿科患者特雷维萨尼乳杆菌菌血症病例。
