Pathogens found in stool.
Two out of all the organisms found in stools which are pathogens to our body are Vibrio cholerae and Campylobacter jejuni
Vibrio cholerae
Vibrio cholerae species belong to the gram-negative bacteria group. It is a facultative anaerobie and curved rod in shape. It is motile and moves by its single flagella. Vibrio cholerae is also identified by being oxidase positive and does not produce hydrogen sulfide and gas Kliger Iron agar.
Vibrio cholerae can be found water surface in many parts of the world.
Below shows a picture of Vibrio cholerae species.
Pathogenicity
Vibrio cholerae causes Cholera in humans. It is an acute intestinal infection and is transmitted to human through contaminated water and food, or through uncooked food such as shellfish and other seafood.
One of the symptoms that people with cholera have is diarrhea. It is caused by a toxin produced by the organism which targets our epithelial cells and that explains for the watery stool appearance in patients infected by Cholera.
Campylobacter jejuni
Campylobacter jejuni is a gram negative, spiral shaped and motile organism.It is a microaerophilic organism therefore, it cannot survive in an environment with high level of oxygen. This organism is usually in found in poultry and contaminated water or sometimes even unpasteurized milk.
Below shows a picture of a Campylobactor jejuni species.
Pathogenesis
The name of the infection caused by this organism is called Camphylobactoriosis. People who are infected by this bacterium have symptoms such as: bloodly, watery or sticky stool. Some people may experience headache, muscle pain and nausea.
