Expanding the Spectrum of Uropathogens: A Rare Human Urinary Tract Infection by Rodentibacter pneumotropicus.

Pasteurella pneumotropica (now reclassified as Rodentibacter pneumotropicus) is a gram-negative coccobacillus primarily associated with rodents, with human infections being exceedingly rare. We report an unusual case of urinary tract infection (UTI) caused by P. pneumotropica in a 56-year-old man with multiple comorbidities, including chronic kidney disease (CKD), type 2 diabetes mellitus, systemic hypertension, and coronary artery disease (status post pacemaker insertion), who experienced multiple episodes of urinary tract Infection over a period of two years. His latest urine culture revealed growth of Pasteurella pneumotropica, a rare zoonotic gram-negative organism not commonly implicated in human disease. This case contributes to expanding the current understanding of human infections caused by Rodentibacter pneumotropicus, emphasizing the need for clinical awareness, microbiological vigilance, and careful antimicrobial stewardship.
