Postmortem bacteriology examinations have been a controversial topic over the years, though the value of postmortem bacteriology cultures remains promising. The aim of this study was to review the postmortem bacteriological sampling procedures and results in a single centre in Bucharest over a period of 10 years. Material and methods: The present study was a retrospective, single-center study, performed at the Mina Minovici National Institute of Legal Medicine in Bucharest, Romania, from 2011–2020. Results: Postmortem bacteriology was requested 630 forensic autopsies, 245 female (38.9%) and 385 male (61.1%), age range 0 and 94 years, median age of 52 years. Deaths occurred in hospital for 594 cases (94.3%) and out-of-hospital for 36 cases (5.7%—field case). Blood cultures were requested in the majority of cases, followed by tracheal swabs and lung tissue. In-hospital and out of hospital deaths did not differ significantly regarding the number of microorganisms identified in a positive blood culture. Postmortem bacteriology cultures of the respiratory tract showed a statistically significant association to microscopically confirmed lung infections. Conclusions Postmortem sampling for bacteriology testing in our center in Bucharest is heterogeneous with a high variation of patterns. A positive blood culture result for Staphylococcus species without the identification of a specific microorganism is more likely due to postmortem contamination.
Healthcare-associated infections are a major concern for healthcare systems around the world. Microorganisms developing resistance to potent antibiotics are an urgent threat to public health. The present study is a retrospective, single-center study performed at the Mina Minovici National Institute of Legal Medicine, Bucharest, Romania, over a period of ten years (2011-2020). Autopsies for deaths occurring in the hospital setting for which postmortem bacteriological examination was solicited were screened and the recovered data consisted of demographics, hospital stay duration, autopsy data, and postmortem microbiology. In the 516 autopsies recovered we found that carbapenemase-producing Enterobacteriaceae (CPE) isolates from postmortem bacteriology results increased in 2019. Positive postmortem microbiology results were associated with histological infection in over 80% of cases. Positive results for healthcare-related pathogens were associated with prolonged hospital stay. In our data vancomycin-resistant enterococci were isolated from 2015. Postmortem bacteriology results from medico-legal autopsies mirror antimicrobial resistance trends from hospital settings with several limitations due to the scarcity of solicitations.
