First case report of isolation of Micrococcus lylae from urinary catheter of a 50-year-old woman suffering from malignancy.

Introduction: 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.

Methodology: 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.

Results: 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.

Conclusions: 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.
