Vibrio cholerae is a species of Gram-negative, facultative anaerobe and comma-shaped bacteria. [1] The bacteria naturally live in brackish or saltwater where they attach themselves easily to the chitin-containing shells of crabs, shrimp, and other shellfish.
Cholera is caused by a number of types of Vibrio cholerae, with some types producing more severe disease than others. [2] It is spread mostly by unsafe water and unsafe food that has been contaminated with human feces containing the bacteria. [2] Undercooked shellfish is a common source. [9] Humans are the only known host for the bacteria. [2]
However, Vibrio Müller, 1773 became regarded as the name of a zoological genus, and the name of the bacterial genus became Vibrio Pacini, 1854. [12] Filippo Pacini isolated micro-organisms he called "vibrions" from cholera patients in 1854, because of their motility. [13] In Latin "vibrio" means "to quiver". [14]
Inhabitants of fresh or salt water, several species are pathogenic, including the type species Vibrio cholerae, which is the agent responsible for cholera. Most bioluminescent bacteria belong to this family, and are typically found as symbionts of deep-sea animals. [1]
Scanning electron microscope image of Vibrio cholerae, the bacterium that causes cholera. The germ theory of disease is the currently accepted scientific theory for many diseases. It states that microorganisms known as pathogens or "germs" can cause disease.
Researchers have now analyzed bacterial samples collected since 2015 from cholera patients across six regions in Bangladesh and identified a set of unique genes and mutations in the strain that ...
Vibrio vulnificus is a species of gram-negative, motile, curved rod-shaped (bacillus), 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. [7]
