## TL;DR

A 15-year-old child had acute appendicitis caused by two rare bacteria, Haemophilus influenzae and Enterobacter cloacae, highlighting the need for thorough testing.

## Contribution

The paper reports a rare dual bacterial infection causing appendicitis, emphasizing the importance of comprehensive microbiological analysis.

## Key findings

- Acute appendicitis was caused by Haemophilus influenzae and Enterobacter cloacae in a 15-year-old patient.
- The case highlights the need to consider uncommon pathogens in appendicitis diagnosis.
- Thorough microbiological investigation is essential for accurate diagnosis and treatment.

## Abstract

Appendicitis, typically caused by appendiceal lumen obstruction, is a prevalent abdominal surgical emergency worldwide. While most cases involve Enterobacterales, Haemophilus influenzae, primarily known for upper respiratory infections, is infrequently associated with gastrointestinal infections. This article presents an exceptional case of acute appendicitis caused by both Haemophilus influenza and Enterobacter cloacae in a 15-year-old child, highlighting the significance of recognizing uncommon pathogens in appendicitis and emphasizing the necessity for thorough microbiological investigations to refine diagnostic approaches.
