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.
