# An Infected Dog Bite With Neisseria animaloris and Neisseria canis Causing Compartment Syndrome, Necrotizing Fasciitis and Gas Gangrene: A Case Report and Review of the Literature

## TL;DR

A rare case of severe infection caused by Neisseria animaloris and Neisseria canis following a dog bite is successfully treated with surgery.

## Contribution

This is the first reported case of successful surgical treatment of necrotizing fasciitis and gas gangrene caused by Neisseria animaloris and Neisseria canis.

## Key findings

- Neisseria animaloris and Neisseria canis, along with other bacteria, caused severe infection including necrotizing fasciitis and gas gangrene.
- Surgical intervention successfully treated the infection in a 46-year-old female patient.
- The case highlights the rare pathogenic potential of Neisseria animaloris and Neisseria canis in humans.

## Abstract

Neisseria animaloris and Neisseria canis are rare, zoologic microorganisms that are found in the oral and nasal cavities of felines and canines. Though the pathogenicity of Neisseria meningitis and gonorrhea are common, N. canis and animaloris have been far less documented to cause infections in humans and moreover it is exceedingly rare to cause necrotizing fasciitis and gas gangrene. We report the first successful surgical treatment of a 46-year-old female with a case of necrotizing fasciitis, compartment syndrome, and gas formation formed from a bacterial colony involving Neisseria animaloris, Neisseria canis, Bacillus cereus, Strepococcus viridans, coagulase-negative Staphylococcus aureus, and Corynebacterium.
