Final answer:
Vibrio vulnificus and Vibrio parahaemolyticus are bacteria primarily found in warm seawater and are linked to gastrointestinal illnesses, often associated with the consumption of raw seafood.
Step-by-step explanation:
Vibrio vulnificus and Vibrio parahaemolyticus, commonly referred to as V. vulnificus and V. parahaemolyticus, are most commonly found in warm seawater. These bacteria are part of the Vibrionales order and are known to cause various forms of gastrointestinal illness in humans. V. vulnificus is typically associated with the consumption of raw seafood and can lead to serious infections like cellulitis and septicemia, while V. parahaemolyticus is also linked to seafood consumption and causes symptoms such as watery diarrhea, nausea, and abdominal cramps. Both of these bacteria can be cultured from blood, stool, or wounds for diagnosis and are treated with antibiotics like tetracycline and ciprofloxacin in severe cases.
