Aeromonas caviae: A rare case of hepatic abscess

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.
