Non-cholera Vibrio infections - Symptoms, diagnosis and.

Vibrio cholerae is a Gram-negative, comma-shaped bacterium.The bacterium's natural habitat is brackish or saltwater where they attach themselves easily to the chitin-containing shells of crabs, shrimps, and other shellfish. Some strains of V. cholerae cause the disease cholera, which can be derived from the consumption of undercooked or raw marine life species.

Vibrio cholerae Non-O1, Non-O139 Serogroups and Cholera.

Introduction. Vibrio cholerae, gram-negative bacteria, are ubiquitous in the aquatic environment.Till now, there are more than 200 serogroups of V. cholerae within the species. Although V. cholerae O1 is the notorious strain that can cause epidemic or pandemic diarrheal disease—cholera, emerging infections due to non-O1 V. cholerae has become another unneglectable problem.We identified 281 Vibrio cholerae non-O1, non-O139 strains from patients with diarrhea in Kolkata, India. Cholera-like diarrhea was the major symptom (66.0%); some patients (20.3%) had severe dehydration. These strains lacked the ctxA gene but many had hlyA, rtxA, and rtxC genes. Pulsed-field gel electrophoresis showed no genetic link among strains.Cholera is an infection of the small intestine by some strains of the bacterium Vibrio cholerae. Symptoms may range from none, to mild, to severe. The classic symptom is large amounts of watery diarrhea that lasts a few days. Vomiting and muscle cramps may also occur. Diarrhea can be so severe that it leads within hours to severe dehydration and electrolyte imbalance.


As pointed out in the December, 2010, editorial,1 the ongoing cholera outbreak in Haiti placed this diarrhoeal infectious disease at the forefront of the global public health agenda. As of Dec 3, 2010, WHO reported 121 518 cases, and 2591 deaths associated with cholera infection. Since Haiti was not previously affected by cholera during the current seventh pandemic its population is more.Cholera, an acute infection of the small intestine caused by the bacterium Vibrio cholerae and characterized by extreme diarrhea with rapid and severe depletion of body fluids and salts. Cholera has often risen to epidemic proportions in sub-Saharan Africa and South Asia, particularly in India and Bangladesh.In the past two centuries, seven pandemics (global epidemics) of cholera have carried.

Cholera Outbreak in Haiti Vibrio cholerae is a bacterium that infects the intestines of humans (CDC, 2016). While there are several strains of vibrio cholerae, only two types have been known to cause cholera outbreaks and only one (type O1) is responsible for outbreaks globally (WHO, 2015). Cholera infection is an acute diarrheal disease (CDC, 2016). It is extremely virulent and can affect.

Vibrio cholerae causes fatal diarrheal disease cholera in humans due to consumption of contaminated water and food. To instigate the disease, the bacterium must evade the host intestinal innate immune system; penetrate the mucus layer of the small intestine, adhere and multiply on the surface of microvilli and produce toxin(s) through the action of virulence associated genes. V. cholerae O1.

Author Summary Vibrio cholerae serogroup O1 is thought to be the sole causative agent for cholera in Bangladesh and most of the high risk developing countries. Whilst historically Vibrio cholerae serogroup O139 has been seen to cause sporadic disease, the overall numbers of reported O139 clinical cases are low, with none reported in Bangladesh since 2005.

Two serotypes, or strains, of V. cholerae cause outbreaks of cholera: O1 and O139. While inside a person's body, these strains release the cholera toxin, which causes cells that line the intestine.

Vibrio cholerae is unusual in that it competes in the natural environmental community of bacteria in estuarine and brackish waters worldwide. V. cholerae bacteria can increase their numbers in the environment by successfully infecting humans. For a person to be infected by cholera, the bacteria’s genetic material must be present in the intestine. One person infected with cholera can shed.
