# Klebsiella ozaenae in a Peritonsillar Abscess: A Case Report

## TL;DR

A 29-year-old patient with a peritonsillar abscess had Klebsiella ozaenae isolated, a rare occurrence in such infections.

## Contribution

This case report highlights the rare isolation of Klebsiella ozaenae in a peritonsillar abscess.

## Key findings

- A 29-year-old patient was diagnosed with a peritonsillar abscess.
- Klebsiella ozaenae was isolated from the abscess after drainage.
- This is a rare case of K. ozaenae in a PTA, as few studies have reported it.

## Abstract

A peritonsillar abscess (PTA) is an infection that primarily affects the peritonsillar space. The incidence is estimated to affect 30 per 100,000 individuals annually, with a higher prevalence between the 15- and 30-year-old age groups. The pathogenesis of a PTA is a crucial step in effective management and prevention. Typically, a PTA has a polymicrobial etiology, aerobic, and anaerobic bacteria of oral flora. Multiple papers in the literature have studied the incidence of Klebsiella species in PTA cases. However, few studies have isolated Klebsiella ozaenae in a PTA. We present a case of a 29-year-old patient who was admitted as a case of a PTA. He underwent an incision and drainage of the right PTA in the operation room. A significant amount of purulent fluid was drained with a positive culture of K. ozaenae.
