Vibrio alginolyticus is a bacterium that belongs to the Vibrio genus, which is a group of gram-negative, motile, and rod-shaped bacteria. It is a halophilic (salt-loving) bacterium commonly found in marine environments, such as estuaries, coastal waters, and seafood, where it is considered a normal inhabitant. This bacterium is also known to thrive in brackish water, meaning it can withstand a mixture of fresh and saltwater.
Vibrio alginolyticus is typically associated with a range of infections in both humans and animals. In humans, it can cause various diseases, primarily gastroenteritis, wound infections, and otitis externa (swimmer's ear). Gastroenteritis is characterized by symptoms like diarrhea, abdominal cramping, vomiting, nausea, and sometimes fever. Wound infections result from direct contact with contaminated water, causing infections at the site of injury. Otitis externa, commonly affecting swimmers, refers to an inflammation of the outer ear canal.
In animals, Vibrio alginolyticus can cause infections in marine mammals, fish, and shellfish. It is known to be a significant pathogen in aquaculture, particularly affecting shrimp and fish. In infected animals, Vibrio alginolyticus can cause disease symptoms like skin lesions, fin rot, septicemia, and high mortality rates.
Due to its association with human and animal infections, Vibrio alginolyticus is considered a potentially harmful bacterium. Proper hygiene practices, such as thoroughly cooking seafood and maintaining clean wound care, can help prevent Vibrio alginolyticus infections.
