ABSTRACT

Multi-drug resistant pathogens are a global problem. Flies are a potential vector of multi-drug resistant pathogens, which can be particularly dangerous in the hospital environment. This study aimed to evaluate flies as vectors of alert pathogens. The research material consisted of 100 flies (Musca domestica (46.0%), Lucilia sericata (28.0%), and Calliphora vicina (26.0%)) collected at the University Hospital No. 1 dr. A. Jurasz in Bydgoszcz (Poland) in 2018–2019 (summer months). The presence of bacteria of the genera: Enterococcus, Staphylococcus, Escherichia, Leclercia, Citrobacter, Hafnia, Providencia, Proteus, Enterobacter, Klebsiella, Raoultella, Morganella, Moellerella, Bordetella, Pantoea, Serratia, Plesiomonas, Wohlfahrimonas, and Lelliottia was confirmed. The most frequently isolated species included: Enterococcus faecalis (n = 64), Escherichia coli (n = 43) and Moellerella wisconsensis (n = 24). The infection rate and antibiotic resistance of bacteria were assessed. One strain of Proteus mirabilis (isolated from Calliphora vicina) produced ESBLs (extended-spectrum beta-lactamases). The infection rate was 0.38%, 0.26%, and 0.20% for Musca domestica, Lucilia sericata, and Calliphora vicina, respectively. The flies from a hospital area were not a vector of alert pathogens. Monitoring flies as potential vectors of pathogens is an important aspect of public health, especially for hospitalized patients.

摘要

多重耐药病原体是一个全球性问题。苍蝇是多重耐药病原体的潜在载体，在医院环境中可能特别危险。本研究旨在评估苍蝇作为警报病原体的载体。研究材料包括在大学第一医院收集的 100 只苍蝇（ Musca domestica (46.0%)、Lucilia sericata (28.0%) 和Calliphora vicina (26.0%)）。A. 2018-2019 年（夏季）比得哥什（波兰）的 Jurasz。存在的细菌属：肠球菌属、葡萄球菌属、埃希氏菌属、莱克勒氏菌属、柠檬酸杆菌属、哈夫尼亚属、普罗维登斯氏菌属、变形杆菌属、肠杆菌属、克雷伯氏菌属、拉乌尔氏菌属、摩根氏菌属、穆勒氏菌属、博德特氏菌属、泛菌属、沙雷氏菌属、Plesiomonas、Wohlfahrimonas，Lelliottia得到了证实。最常分离的物种包括：粪肠球菌（n = 64）、大肠杆菌（n = 43）和威斯康星莫勒氏菌（ n = 24）。评估细菌的感染率和抗生素耐药性。一株奇异变形杆菌（从Calliphora vicina 中分离）产生 ESBL（超广谱 β-内酰胺酶）。Musca domestica、Lucilia sericata和Calliphora vicina的感染率分别为0.38%、0.26%和0.20%， 分别。来自医院区域的苍蝇不是警觉病原体的媒介。监测苍蝇作为病原体的潜在载体是公共卫生的一个重要方面，特别是对于住院患者。
