Some strains of V. cholerae are pathogenic to humans and cause a deadly disease called cholera, which can be derived from the consumption of undercooked or raw marine life species or drinking contaminated water. [2] V. cholerae was first described by Félix-Archimède Pouchet in 1849 as some kind of protozoa.
CTXφ is generally present and integrated into the genome of the V. cholerae bacterium, and more rarely in a virion from outside the bacterium. While integrated into the bacterial genome, CTX prophages are found on each of the two chromosomes (in the O1 serogroup of V. cholerae) or arranged in tandem on the larger chromosome (in the El Tor biotype of V. cholerae).

Vibrio cholerae str. El Tor El Tor is a particular strain of the bacterium Vibrio cholerae , the causative agent of cholera . Also known as V. cholerae biotype eltor, it has been the dominant strain in the seventh global cholera pandemic .
TCBS agar plate of Vibrio Cholerae (left) and Vibrio parahaemolyticus (right) Several species of Vibrio are pathogens. [15] Most disease-causing strains are associated with gastroenteritis, but can also infect open wounds and cause sepsis. [16]
Vibrio vulnificus is a species of Gram-negative, motile, curved rod-shaped (vibrio), pathogenic bacteria of the genus Vibrio. Present in marine environments such as estuaries, brackish ponds, or coastal areas, V. vulnificus is related to V. cholerae, the causative agent of cholera. [3] At least one strain of V. vulnificus is bioluminescent. [4]
Cholera (/ ˈ k ɒ l ər ə /) is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. [4] [3] Symptoms may range from none, to mild, to severe. [3]The classic symptom is large amounts of watery diarrhea lasting a few days. [2]

The PEL22A strain showed that the genes that regulate the bacteriophage CTXΦ, the main cause of virulence in Vibrio cholerae, were present but lack the genes for cholera toxin, ctxA and ctxB. The strain did contain hlyA gene which codes for hemolysin, an endotoxin found in most Vibrio species. [4]
