# A Case of Rahnella aquatilis Bacteraemia After the Receipt of an Unlicensed Intravenous Vitamin Infusion, the First to be Reported in the UK

## TL;DR

A healthy woman developed a rare bacterial infection after receiving an unlicensed IV vitamin infusion, marking the first UK case of Rahnella aquatilis bacteraemia linked to this source.

## Contribution

This is the first reported case in the UK linking R. aquatilis bacteraemia to an unlicensed intravenous vitamin infusion.

## Key findings

- A previously healthy woman developed R. aquatilis bacteraemia following an unlicensed IV vitamin infusion.
- The case highlights the potential risks of unregulated intravenous vitamin treatments.
- The infection is linked to presumed contamination of the infusion.

## Abstract

Rahnella aquatilis is a Gram-negative bacterium commonly found in the environment. Previously associated with food spoilage, it has in the past been responsible for causing infection in humans, usually as an opportunistic pathogen. We report a case of a previously healthy female who was diagnosed with R. aquatilis bacteraemia. Careful history-taking confirmed she had received an intravenous infusion of presumed-contaminated vitamins immediately prior to presentation. As the global beauty-industry continues to expand, we should be vigilant of future similar cases.
