Abstract

Post-mortem microbiological tests are one of the basic methods for diagnosing the etiology of infections in forensic pathology. One of the major groups of microorganisms abundant in various parts of the human body during life and after death is spp. Depending on the area of the body involved and the patient's condition, enterococci can be considered to be a microbiome, transient flora or a pathogen responsible for infection. The data used for the analysis were 12 medico-legal autopsy and microbiological reports. spp. was isolated in 10 out of 12 cultures of blood samples collected post-mortem. The abdominal origin of enterococci in the blood was detected in 8 cases. The non-abdominal origin of enterococci in the blood was associated with a skin and soft tissue infection, purulent pneumonia and infective endocarditis. These results suggest that enterococci may be considered a cause of severe infections and with high likelihood. Microbiological cultures are a valuable source of information for helping to confirm the cause of infection. Interpretation of the results of post-mortem examinations must be carried out on the basis of data collected before and after death with the participation of specialists from various fields.

摘要

尸检微生物学检测是法医病理学中诊断感染病因的基本方法之一。在生前和死后人体各个部位大量存在的主要微生物群之一是肠球菌属。根据受累身体部位和患者状况,肠球菌可被视为微生物群、暂住菌丛或引起感染的病原体。用于分析的数据为12份法医学尸检和微生物学报告。在12份死后采集的血样培养物中,有10份分离出了肠球菌属。8例检测出血液中肠球菌的来源为腹部。血液中肠球菌的非腹部来源与皮肤及软组织感染、化脓性肺炎和感染性心内膜炎有关。这些结果表明,肠球菌很可能可被视为严重感染的病因。微生物培养是有助于确认感染病因的宝贵信息来源。必须在各领域专家的参与下,根据生前和死后收集的数据对尸检结果进行解读。
