5 Must Know Facts For Your Next Test

1. Vibrionales includes the well-known genus Vibrio, which contains species like Vibrio cholerae, the causative agent of cholera.
2. Members of Vibrionales are typically Gram-negative bacteria with polar flagella, aiding in their motility.
3. These bacteria often thrive in marine or estuarine environments where they can be free-living or associated with host organisms.
4. Vibrio species can produce toxins that lead to severe gastrointestinal diseases in humans and other animals.
5. Bioluminescence is a notable feature in some Vibrionales species, such as Vibrio fischeri, which forms symbiotic relationships with certain marine animals.
