Abstract:
We report a case of Pasteurella dagmatis wound infection in an immunocompromised HIV infected patient after bite by a marine carnivore in Caribbean Sea (Dominican Republic), presumably a muraenidae. Identification of the Pasteurella species from wound sampling was obtained twice by mass spectrometry and confirmed by 16S RNA sequencing.
Insights
A Pasteurella dagmatis wound infection occurred in an immunocompromised patient with HIV after a marine animal bite. Diagnosis was confirmed using mass spectrometry and 16S RNA sequencing.
Area of Science:
- Microbiology
- Infectious Diseases
- Marine Biology
Background:
- Human immunodeficiency virus (HIV) infection compromises the immune system, increasing susceptibility to opportunistic infections.
- Marine environments harbor diverse microorganisms, some of which can cause infections in humans through bites or wounds.
Observation:
- An immunocompromised patient with HIV presented with a wound infection after a bite from a marine carnivore, likely a muraenidae (moray eel), in the Dominican Republic.
- The patient's medical history of HIV infection was a significant factor in their vulnerability.
Findings:
- The wound sample was repeatedly identified as Pasteurella dagmatis using mass spectrometry.
- The identification was further confirmed through 16S RNA sequencing, ensuring accurate species determination.
- This case highlights a rare instance of Pasteurella dagmatis infection transmitted from a marine animal.
Implications:
- This case underscores the importance of considering marine-associated pathogens in wound infections, especially in immunocompromised individuals.
- Accurate identification of the causative agent is crucial for appropriate treatment and management of Pasteurella infections.
- Further research into marine-associated zoonotic diseases is warranted to improve prevention and clinical outcomes.
