Infection by multidrug-resistant Chryseobacterium indologenes in cases of obstructive uropathy: Case series with short review

Chryseobacterium spp. are Gram-negative, aerobic, nonfermentative, oxidase-positive and catalase-positive nonmotile bacilli that produce yellow to orange pigment. We report three cases of complicated urinary tract infections (UTIs) caused by Chryseobacterium indologenes in patients with obstructive uropathy. The first case was a known case of diabetes mellitus with right emphysematous pyelonephritis and obstructive uropathy due to prostate enlargement. The patient underwent dialysis for renal failure and subsequently developed UTI by multidrug-resistant C. indologenes. The second case was 72 years old known case of ischemic heart disease. He had acute retention of urine that was relieved after catheterization. He had obstructive uropathy due to transitional cell carcinoma of the bladder and had developed UTI due to C. indologenes. The third case was 38-year-old unmarried female admitted for difficulty in micturition and was catheterized for the same. Obstructive uropathy was due to two fibroids, first fibroid was 9.2 cm × 9.2 cm sized subserosal in the lower segment of the uterus on posterior wall (posterior cervical fibroid) and second fibroid was approximately 1.5 cm × 2.1 cm fundal fibroid; however, the patient developed UTI on the 7th day of catheterization due to C. indologenes. These cases were treated by relieving urinary obstruction and appropriate antibiotic treatment as per antibiotic susceptibility test results.
