Abstract

Aeromonas salmonicida is a well-known pathogen in salmonid fishes. It was believed to be non-pathogenic to humans because of inability to grow at 37°C. Here we present a case of a woman in her 20s who was diagnosed with abdominal tuberculosis 6 months previously but had not been compliant with the treatment. She presented with occasional febrile episodes, whitish vaginal discharge, burning micturition, anal ulcer, whitish discharge from mouth and recent onset breathlessness. Patient tested serologically positive for HIV-1, and A. salmonicida was isolated from urine sample. Patient was treated with antituberculosis therapy, antiretroviral therapy and antimicrobials. She showed marked improvement over the next few weeks. This case highlights the importance of recognition of rare organisms, especially in immunocompromised patients. The identification and subsequent treatment of such pathogens have improved since the advent of automated identification systems.
