Dif是什么ference Between Vibrio Cholerae and Vibrio Parahaemolyticus

Thekey differencebetween Vibrio cholerae and Vibrio parahaemolyticusis thatV. choleraeis a food-bornepathogenicbacterium that causes cholera in humans whileV. parahaemolyticusis a food-borne pathogenic bacterium that causes acutegastroenteritis在人类身上。

Vibriois a genus of gram-negative curved rod-shaped bacteria found in marine environments. This genus consists of many species; among them, several species are human pathogens.V. parahaemolyticus, V. vulnificus,andV. cholerae are three species that cause food-borne human infections. They are the major causes of human gastrointestinal illnesses.V. choleraeis the causative agent of cholera, whileV. parahaemolyticusis the causative agent of acute gastroenteritis. Both species produce toxins.

What is Vibrio Cholerae?

V. choleraeis a comma-shaped, gram-negative, facultative anaerobic bacterium that affects humans and causes cholera. Cholera is a disease characterized by waterydiarrhoeaand vomiting. It can lead to severe dehydration or hypovolemic shock, as well.

V. choleraenaturally occurs in brackish and saltwater. It is a highly motile bacterium with a single polar flagellum. This bacterium has many serotypes among them; some are non-pathogenic, while certain serotypes, especially the two serotypes O1 and O139, are pathogenic.V. choleraeinfections occur through contaminated foods and water. Therefore,V. cholerae infections are more common in countries or in populations that live with poor water, sanitation, and hygiene infrastructures.

What is Vibrio Parahaemolyticus?

V. parahaemolyticus是革兰氏阴性兼性anaero comma-shapedbic bacterium found in marine and estuarine environments. This bacterium causes acute gastroenteritis worldwide. Symptoms of gastroenteritis are watery diarrhoea, abdominal cramping, nausea, vomiting, and fever. This bacterium can be responsible for wound infections as well when open wounds are exposed to seawater. This bacterium produces two hemolysins: a thermostable direct hemolysin (TDH) and/or a thermostable-related hemolysin (TRH), which are toxins related to gastroenteritis.

V. parahaemolyticusis abundant in shellfish, and consumption of raw seafood is a major cause ofV. parahaemolyticushuman infections. In order to prevent infections caused by this bacterium, proper storage and appropriate cooking of seafood are necessary. Furthermore, people who have open wounds should not be exposed to brackish or saltwater. Diagnosis ofV. parahaemolyticasinfections can be made by stool cultures. Moreover, blood and wound cultures can be observed if there are wound infections.

What are the Similarities Between Vibrio Cholerae and Vibrio Parahaemolyticus?

• choleraeandV. parahaemolyticusare two bacteria belonging to the same family.
• They are found in marine environments abundantly.
• Both are motile bacteria.
• They have a single polar flagellum.
• Structurally, they are comma-shaped and gram-negative.
• They cause food-borne human infections.
• They produce toxins and are human pathogens.

Dif是什么ference Between Vibrio Cholerae and Vibrio Parahaemolyticus?

The causative agent of cholera is the food-borne pathogenic bacterium calledV. cholerae while the causative agent of acute gastroenteritis is the food-borne bacterium calledV. parahaemolyticus. So, this is the key difference between Vibrio cholerae and Vibrio parahaemolyticus. Moreover, ulikeV. cholera,V. parahaemolyticuscauses wound infections as well.

The below infographic lists the difference betweenVibriocholeraeand弧菌parahaemolyticusin tabular form for side by side comparison.

Summary – Vibrio Cholerae vs Vibrio Parahaemolyticus

V. choleraeandV. parahaemolyticusare comma-shaped, gram-negative aerobic or facultatively anaerobic bacteria that cause food-borne human infections. Ingestion of food and water contaminated with these bacteria cause human gastrointestinal illnesses.V. choleracauses cholera, whileV. parahaemolyticuscauses acute gastroenteritis.V. parahaemolyticusalso causes wound infections. Thus, this is the key difference betweenVibrio choleraeand弧菌parahaemolyticus.
