# Aeromonas caviae: A rare case of hepatic abscess

## TL;DR

This paper reports the first known case of a liver abscess caused by Aeromonas caviae in a 75-year-old woman with a history of cancer.

## Contribution

This is the first documented case of hepatic abscess caused by Aeromonas caviae.

## Key findings

- A 75-year-old woman with a history of cancer was diagnosed with A. caviae bacteremia and liver abscesses.
- The patient was successfully treated with two months of intravenous antibiotics.
- The case highlights the rare occurrence of A. caviae liver abscess and raises concerns about public health impacts of global warming.

## Abstract

The aim of this report is to present, to our knowledge, the first case of Aeromonas (A.) caviae liver abscess.

The following manuscript describes a case of a 75-year-old female patient with past medical history of pancreatic cancer, lung cancer, hypothyroidism, hypertension and chronic venous insufficiency who was diagnosed with A. caviae bacteremia and multiple liver abscesses in the right lobe. The patient was treated conservatively, with intravenous antibiotics for two months with adequate recovery.

Aeromonas spp. is a Gram-negative, facultative anaerobic microorganism that lives in aquatic environments. There are many subtypes of Aeromonas spp., with the commonest being A. hydrophila, A. sobria and A. caviae. They tend to cause gastrointestinal and hepatobiliary disease in immunocompromised people, mostly those with underlined disease or malignancy of the hepatobiliary tract.

Aeromonas spp. has been identified in chlorinated tap water, worldwide. Global warming contributes not only to the reproduction of more bacteria, but also to the development of antibiotic resistance genes and biofilms. Besides the fact that liver abscess due to Aeromonas caviae is rare; the following report highlights a major, public health concern, that is Global warming, and the devastating impact it can have on healthcare.
