Catheter-associated urinary tract infection (CAUTI) is the most common healthcare-associated infection which tends to cause increased length of morbidity, and mortality of patients, in addition to increased bacterial resistance to antibiotics.
In the present study, urinary catheters were collected from a 50-year-old woman suffering from malignancy, bedridden, and having urinary incontinence. These catheters were processed in laboratory for isolation of bacteria using standard procedures.
Microbiological examination of the urinary catheters by biochemical, physiological, and VITEK 2 compact system revealed bacterial infection caused by Micrococcus lylae, a Gram-positive microorganism belonging to the family Micrococcacea. These Gram-positive bacteria were found to be susceptible to streptomycin, erythromycin, cefotaxime, neomycin, kanamycin, vancomycin, azithromycin, chloramphenicol, and tetracycline. Bacterial species were confirmed using 16s rRNA sequencing.
The sequences were found to have 99% similarity with Micrococcus lylae. This is the first report of isolation of Micrococcus lylae from the urinary catheter.
导管相关尿路感染（CAUTI）是最常见的医疗保健相关感染，除了增加细菌对抗生素的耐药性外，还会导致患者发病时间和死亡率延长。
在本研究中，从一名 50 岁患有恶性肿瘤、卧床不起和尿失禁的女性身上采集了导尿管。这些导尿管通过标准程序在实验室中进行细菌分离处理。
通过生化、生理和 VITEK 2 紧凑型系统对导尿管进行微生物学检查，发现由革兰氏阳性微生物微球菌引起的细菌感染，属于微球菌科。这些革兰氏阳性细菌对链霉素、红霉素、头孢噻肟、新霉素、卡那霉素、万古霉素、阿奇霉素、氯霉素和四环素敏感。使用 16s rRNA 测序确认细菌种类。
序列与微球菌的相似度为 99%。这是首次从导尿管中分离出微球菌的报告。
