Cholera vaccines are vaccines that are effective at preventing cholera. For the first six months after vaccination they provide about 85percent protection, which decreases to 50percent or 62percent during the first year. After two years the level of protection decreases to less than 50percent. When enough of the population is immunized, it may protect those who have not been immunized (known as herd immunity). The World Health Organization (WHO) recommends the use of cholera vaccines in combination with other measures among those at high risk. With the oral vaccine, two or three doses are typically recommended. The duration of protection is two years in adults and six months in children aged 2–5 years. A single dose vaccine is available for those traveling to an area where cholera is common. In 2010, in some countries an injectable cholera vaccine was available. The available types of oral vaccine are generally safe. Mild abdominal pain or diarrhea may occur. They are safe i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cholera Toxin
Cholera toxin (also known as choleragen and sometimes abbreviated to CTX, Ctx or CT) is AB5 multimeric protein complex secreted by the bacterium ''Vibrio cholerae''. CTX is responsible for the massive, watery diarrhea characteristic of cholera infection. It is a member of the Heat-labile enterotoxin family. History Cholera toxin was discovered in 1959 by Indian microbiologist Sambhu Nath De. Structure The complete toxin is a hexamer made up of a single copy of the A subunit (part A, enzymatic, ), and five copies of the B subunit (part B, receptor binding, ), denoted as AB5. Subunit B binds while subunit A activates the G protein which activates adenylate cyclase. The three-dimensional structure of the toxin was determined using X-ray crystallography by Zhang ''et al.'' in 1995. The five B subunits—each weighing 11 kDa, form a five-membered ring. The A subunit which is 28 kDa, has two important segments. The A1 portion of the chain (CTA1) is a globular enzyme payload t ...

Vibrio Cholerae
''Vibrio cholerae'' is a species of Gram-negative, facultative anaerobe and comma-shaped bacteria. The bacteria naturally live in brackish or saltwater where they attach themselves easily to the chitin-containing shells of crabs, shrimps, and other shellfish. Some strains of ''V. cholerae'' are pathogenic to humans and cause a deadly disease cholera, which can be derived from the consumption of undercooked or raw marine life species. ''V. cholerae'' was first described by Félix-Archimède Pouchet in 1849 as some kind of protozoa. Filippo Pacini correctly identified it as a bacterium and from him, the scientific name is adopted. The bacterium as the cause of cholera was discovered by Robert Koch in 1884. Sambhu Nath De isolated the cholera toxin and demonstrated the toxin as the cause of cholera in 1959. The bacterium has a flagellum at one pole and several pili throughout its cell surface. It undergoes respiratory and fermentative metabolism. Two serogroups called O1 and O139 ...

Vaccines
A vaccine is a biological preparation that provides active acquired immunity The adaptive immune system, also known as the acquired immune system, is a subsystem of the immune system that is composed of specialized, systemic cells and processes that eliminate pathogens or prevent their growth. The acquired immune system ... to a particular infectious disease, infectious or cancer, malignant disease. The safety and effectiveness of vaccines has been widely studied and verified. A vaccine typically contains an agent that resembles a disease-causing microorganism and is often made from weakened or Antigen, killed forms of the microbe, its toxins, or one of its surface proteins. The agent stimulates the body's immune system to recognize the agent as a threat, destroy it, and to further recognize and destroy any of the microorganisms associated with that agent that it may encounter in the future. Vaccines can be prophylaxis, prophylact ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Centers For Disease Control And Prevention
The Centers for Disease Control and Prevention (CDC) is the national public health agency of the United States. It is a United States federal agency, under the Department of Health and Human Services, and is headquartered in Atlanta, Georgia. The agency's main goal is the protection of public health and safety through the control and prevention of disease, injury, and disability in the US and worldwide. The CDC focuses national attention on developing and applying disease control and prevention. It especially focuses its attention on infectious disease, food borne pathogens, environmental health, occupational safety and health, health promotion, injury prevention and educational activities designed to improve the health of United States citizens. The CDC also conducts research and provides information on non-infectious diseases, such as obesity and diabetes, and is a founding member of the International Association of National Public Health Institutes.

Wilhelm Kolle
Wilhelm Kolle (born 2 November 1868 in Lerbach, Osterode am Harz, Lerbach near Osterode am Harz, died 10 May 1935) was a German bacteriologist and hygienist. He served as the second director of the Paul Ehrlich Institute, Royal Institute for Experimental Therapy, succeeding its founder, the Nobel laureate Paul Ehrlich. He was also the original author, with Heinrich Hetsch, of the famous book ''Experimental Bacteriology'', one of the most authoritative works in microbiology in the first half of the 20th century. Following studies of medicine at the universities of University of Göttingen, Göttingen, University of Halle, Halle and University of Würzburg, Würzburg, he became an assistant to Robert Koch at the ''Institut für Infektionskrankheiten'' (Institute for Infectious Diseases) in Berlin (1893–97). In 1897–98 he performed research of rinderpest and leprosy in South Africa, and in 1900, on behalf of the Egyptian government, studied rinderpest in Sudan. In 1901 he became de ...

Waldemar Haffkine
Waldemar Mordechai Wolff Haffkine ( uk, Володимир Мордехай-Вольф Хавкін; russian: Мордехай-Вольф Хавкин; 15 March 1860 Odessa – 26 October 1930 Lausanne) was a Ukrainian-French bacteriologist known for his pioneering work in vaccines. Born into a Jewish family in Odessa, Russian Empire, Haffkin was educated at the University of Odessa and later emigrated first to Switzerland, then to France, working at the Pasteur Institute in Paris, where he developed a cholera vaccine that he tried out successfully in India. He is recognized as the first microbiologist who developed and used vaccines against cholera and bubonic plague. He tested the vaccines on himself. Lord Joseph Lister named him "a saviour of humanity". He was appointed Companion of the Order of the Indian Empire (CIE) in Queen Victoria's 1897 Diamond Jubilee Honours.

Jaume Ferran I Clua
''Jaime Ferrán y Clúa'' (Corbera d'Ebre, 1851 – Barcelona 1929) was a Spanish- French bacteriologist and sanitarian , contemporary of Robert Koch, and said by his fellows to have made some of the discoveries attributed to Koch. As early as 1885, he wrote on immunization against cholera. In 1893, his work on this subject was translated into French with the title ''L'Inoculation préventive contre le Cholera''. Tuberculosis is another disease in which Ferran was always deeply interested. Some of his ideas on the transmission and virulence of tuberculosis are revolutionary. He died in 1929 and was buried in Montjuïc Cemetery, Barcelona Barcelona ( , , ) is a city on the coast of northeastern Spain.

Louis Pasteur
Louis Pasteur (, ; 27 December 1822 – 28 September 1895) was a French chemist and microbiologist renowned for his discoveries of the principles of vaccination, microbial fermentation and pasteurization, the latter of which was named after him. His research in chemistry led to remarkable breakthroughs in the understanding of the causes and preventions of diseases, which laid down the foundations of hygiene, public health and much of modern medicine. His works are credited to saving millions of lives through the developments of vaccines for rabies and anthrax. He is regarded as one of the founders of modern bacteriology and has been honored as the "father of bacteriology" and the "father of microbiology" (together with Robert Koch; the latter epithet also attributed to Antonie van Leeuwenhoek). Pasteur was responsible for disproving the doctrine of spontaneous generation. Under the auspices of the French Academy of Sciences, his experiment demonstrated that in sterilized ...
