Abstract

Parvimonas micra is an obligate anaerobe that forms part of the normal gastrointestinal flora. The advent of matrix-assisted laser desorption ionization time of flight mass spectrometry (MALDI-TOF) and 16s ribosomal RNA gene sequencing has led to increased detection of many rare anaerobic isolates, including Parvimonas micra. Typical risk factors for Parvimonas micra bacteremia include dental procedures or spinal instrumentation. Here, we report a case of Parvimonas micra spondylodiscitis and psoas abscess in a patient with no obvious antecedent risk factors and explore the challenges in isolation of the organism from tissue samples.

摘要

细小病毒是一种专性厌氧菌，是正常胃肠道菌群的一部分。基质辅助激光解吸电离飞行时间质谱（MALDI-TOF）和16s核糖体RNA基因测序的出现导致许多稀有厌氧分离株的检测增加，包括Parvimonasmicra.小孢子菌血症的典型危险因素包括牙科手术或脊柱器械。这里,我们报道了1例患者的脊髓灰质炎和腰大肌脓肿，没有明显的前兆危险因素，并探讨了从组织样本中分离生物体的挑战。
