Very long fusiform gram-negative bacilli were observed after Gram staining of amniotic fluid from a 36-year-old multigravida woman. At 24 hours, pure, abundant growth of smooth, gray, only slightly convex catalase-positive and oxidase-negative colonies measuring about 2 mm were observed. Growth was greater in anaerobic than in aerobic conditions. The bacterium was identified as Leptotrichia trevisanii by matrix-assisted laser desorption ionization time of flight mass spectrometry. Ampicillin and gentamicin were prescribed for chorioamnionitis, and vaginal prostaglandins were administered to terminate the pregnancy. The patient remained afebrile throughout 48 hours and was discharged. Microscopic examination of the placenta revealed severe acute chorioamnionitis with a maternal inflammatory response and abundant bacillary-shaped microorganisms. To our knowledge, this isolate constitutes the first reported case of chorioamnionitis caused by L. trevisanii.
对一名36岁多孕次女性的羊水进行革兰氏染色后，观察到非常长的梭形革兰氏阴性杆菌。24小时后，观察到纯的、丰富生长的光滑、灰色、仅略凸起的菌落，这些菌落过氧化氢酶阳性、氧化酶阴性，大小约2毫米。在厌氧条件下的生长比需氧条件下更好。通过基质辅助激光解吸电离飞行时间质谱法将该细菌鉴定为特氏纤毛菌。给予氨苄西林和庆大霉素治疗绒毛膜羊膜炎，并给予阴道前列腺素以终止妊娠。患者在48小时内一直未发热，随后出院。胎盘的显微镜检查显示严重的急性绒毛膜羊膜炎，伴有母体炎症反应和大量杆菌状微生物。据我们所知，该分离株是首例报道的由特氏纤毛菌引起的绒毛膜羊膜炎病例。
