Cholera is an acute intestinal infection caused by ingestion of food or water contaminated with the bacterium Vibrio cholerae. It has a short incubation period, from less than one day to five days, and produces an enterotoxin that causes a copious, painless, watery diarrhoea that can quickly lead to severe dehydration and death if treatment is not promptly given. Vomiting also occurs in most patients.
What else can I help you with?
The size of vibrio cholerae?
About 1.5 - 2 micrometers long and about 500 nanometers (half a micrometer) wide.
How long does it take for humans to become infected from cholera?
It is dependent on the volume of Vibrio choleraeconsumption, usually by contaminated water or food. After ingestion of of the bacterium Vibrio cholerae, it takes 24 - 48 hrs of incubation before symptoms of Cholera occur. A first sign would be a painless watery diarrhea secretion. Most infestations are asymptomatic. Higher volumes of infestation lead to more severe symptoms.
Can bacterium cause disease?
Yes of course it can . Bacterium is the plural of bacteria so yes it can cause disease but since bacteria reproduce lightening fast it wouldn't stay a bacterium for long
How long do viruses to reproduce?
The time it takes for a virus to reproduce varies depending on the type of virus and conditions present. Some viruses, like the flu, can reproduce and spread quickly within a host, causing rapid onset of symptoms. Other viruses may have a slower replication rate.
How do Cow reproduce?
As long as they are productive.
What is chorlea?
Cholera, sometimes known as Asiatic or epidemic cholera, is an infectious gastroenteritis caused by enterotoxin-producing strains of the bacterium Vibrio cholerae.[1][2] Transmission to humans occurs through eating food or drinking water contaminated with Vibrio choleraefrom other cholera patients. The major reservoir for cholera was long assumed to be humans themselves, but considerable evidence exists that aquatic environments can serve as reservoirs of the bacteria.Vibrio cholerae is a Gram-negative bacterium that produces cholera toxin, an enterotoxin, whose action on the mucosal epithelium lining of the small intestine is responsible for the disease's most salient characteristic, exhaustive diarrhea.[1] In its most severe forms, cholera is one of the most rapidly fatal illnesses known, and a healthy person's blood pressure may drop to hypotensive levels within an hour of the onset of symptoms; infected patients may die within three hours if medical treatment is not provided.[1] In a common scenario, the disease progresses from the first liquid stool to shock in 4 to 12 hours, with death following in 18 hours to several days, unless oral (or, in more serious cases, intravenous) rehydration therapy is provided.[3][4]It is estimated that most cases of cholera are unreported due to poor surveillance systems, particularly in Africa. Fatality rates are 5% of total cases in Africa, and less than 1% elsewhere.[5] For a map of recent international outbreaks, see:[3]

Where do elephants reproduce?
Anywhere as long as they are with the herd
Do raccoons reproduce?
Yes they do reproduce because their are male and female Raccoons
How many polio virus particles could multiply in a 1-mircomtere long bacterium?
zero.
Is a bacterium multi-cellular or unicellular?
unicellular, however sometimes they are associated in groups or long strings.
