Urinary tract infection by Pantoea agglomerans

Abstract

Urinary tract infection is especially common in women, Gram negative aerobic bacteria are responsible for the largest number of cases. Pantoea agglomerans, previously known as Enterobacter agglomerans, is a Gram negative anaerobic bacillus that has rarely been described as a pathogen in humans; Cases of skin infections, osteomyelitis and synovitis have been reported after trauma with plants; and nosocomial infections, especially in immuno- suppressed patients that have been associated with contaminated medical material, with most cases being resistant to betalactams. An uncommon clinical case of cystitis due to Pantoea agglomerans is presented in a 30-year-old woman, immunocompetent, without a history of hospitalization, instrumentation or catheterization of the urinary tract; She was treated with an extended regimen of betalactams, with a favorable response to antibiotic therapy. The diagnosis of urinary infection by P. agglomerans in immunocompetent patients is unusual, its scarce isolation could be related to the difficulty of identifying this bacterium in biological samples and resistance to antibiotic therapy could be associated in hospitalized patients with the extensive and prolonged administrationof antibiotics in your hospital stay. For this reason, it is recommended to request urine culture and its respective antibiogram in patients with symptomatic urinary tract infection to have information on the isolated pathogen and provide adequate antimicrobial treatment contemplating the most appropriate scheme.
