# Actinomyces neuii Causing Right-Sided Infective Endocarditis: A Case-Based Literature Review

## TL;DR

A rare case of right-sided infective endocarditis caused by Actinomyces neuii in a middle-aged woman is reported and reviewed.

## Contribution

This is the first reported case of A. neuii causing right-sided infective endocarditis in a middle-aged female without valvular disease.

## Key findings

- A middle-aged female was diagnosed with right-sided infective endocarditis caused by A. neuii.
- The patient had no residual or prosthetic valvular disease.
- This case expands the known clinical manifestations of A. neuii infections.

## Abstract

Actinomyces neuii (also known as Winkia neuii nowadays), quite different from its genus,is a facultatively anaerobic organism that rarely causes human infections.Like the rest of its genus, it usually has a good prognosis. In this case report, we present an interesting case of a middle-aged female who presented to the emergency department (ED) with fever and dyspnea, eventually diagnosed with infective endocarditis (IE) caused by A. neuii. To the best of our knowledge, it is the first reported case of A. neuii causing right-sided infective endocarditis in a middle-aged female with no residual or prosthetic valvular disease.
