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

## TL;DR

A rare urinary tract infection caused by Rodentibacter pneumotropicus, previously known as Pasteurella pneumotropica, is reported in a man with multiple health issues.

## Contribution

This is the first reported case of human urinary tract infection caused by Rodentibacter pneumotropicus.

## Key findings

- A 56-year-old man with chronic health conditions had a UTI caused by Pasteurella pneumotropica.
- The infection highlights the potential for this rodent-associated bacterium to cause disease in humans.
- The case emphasizes the importance of clinical awareness and antimicrobial stewardship for rare pathogens.

## Abstract

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.
