The discovery of how bacteria communicate may lead to new types of antibiotics and ways of improving actions of good bacteria Bonnie Bassler spends her days listening to bacteria talk to one another, and what she has overheard may surprise you. It turns out that these tiny, single-celled organisms are taking roll call. Each whispered conversation is an attempt to count how many of their own kind are present before they try to mount an attack on their host organism, which might very well be...

A five-year follow up study in Bangladesh finds that women are literally wearing the answer to better health for themselves, their families and even their neighbors. Using the simple sari to filter household water protects not only the household from cholera, but reduces the incidence of disease in neighboring households that do not filter. The results of this study appear in the inaugural issue of mBioâ“ž¢, the first online, open-access journal published by the...

In a new study, Dartmouth researchers describe the structure of a protein called ToxT that controls the virulent nature of Vibrio cholerae, the bacteria that causes cholera. Buried within ToxT, the researchers were surprised to find a fatty acid that appears to inhibit ToxT, which prevents the bacteria from causing cholera. Cholera, which causes acute diarrhea, can be life threatening, and, according to the World Health Organization, cholera remains a serious threat to global health. Doctors...

Mankind may finally have a weapon to fight two of the world's deadliest diseases. A University of Central Florida biomedical researcher has developed what promises to be the first low-cost dual vaccine against malaria and cholera. There is no FDA approved vaccine to prevent malaria, a mosquito-borne illness that kills more than 1 million people annually. Only one vaccine exists to fight cholera, a diarrheal illness that is common in developing countries and can be fatal. The lone vaccine is...

PARIS, January 14 /PRNewswire/ -- The Agence de Medecine Preventive (AMP) has received a three-year grant of $4.9 million from the Bill & Melinda Gates Foundation to create a consortium supporting cholera prevention and control in Africa. AMP and the African Field Epidemiology Network (AFENET) will be the core members of the consortium, which will include several other leading health organizations from around the world. The consortium will establish an African Cholera...

River discharge and regional climate are keys Cholera, an acute diarrheal disease caused by the bacterium Vibrio cholerae, has reemerged as a global killer. Outbreaks typically occur once a year in Africa and Latin America. But in Bangladesh the epidemics occur twice a year "“ in the spring and again in the fall. Scientists have tried, without much success, to determine the cause of these unique dual outbreaks "“ and advance early detection and prevention efforts "“ by...

Despite evidence that low-cost diarrhea treatments such as lower osmolarity oral rehydration salts (ORS) and zinc supplements could drastically reduce the number of deaths among children, little progress has been made in implementing these life-saving techniques, according to researchers at the Johns Hopkins Bloomberg School of Public Health. They examined the implementation of current treatment guidelines and found that few countries are equipped to quickly adapt policies, and many struggle...

Researchers in Australia are developing diversionary tactics to fool disease-causing bacteria in the gut. Many bacteria, including those responsible for major gut infections, such as cholera, produce toxins that damage human tissues when they bind to complex sugar receptors displayed on the surface of cells in the host's intestine. At the Society for General Microbiology's meeting at Heriot-Watt University, Edinburgh, today (8 September), Professor James Paton and colleagues from the...

It is based on detecting short, repetitive DNA segments in the genome of bacteria. Every single bacterial strain has such characteristic repeats. "With this method we are able to identify bacterial strains as well as clarify their genetic relationships. Furthermore, we can show how new pathogenic variants develop," says Manfred Höfle, researcher at the HZI. The results have now been published in the current issue of the scientific journal "Applied and Environmental Microbiology". The...

Vibrio vulnificus is a species of Gram-negative, motile, curved, rod-shaped bacteria of the Vibrio Genus. Hollis et al. first reported it in 1976. It was given the name Beneckea vulnifica by Reichelt et al. in 1976 and in 1979 Vibrio vulnificus by Farmer. V. vulnificus is related to V. cholerae and is present in marine environments such as estuaries, brackish ponds, or coastal areas. It causes an infection often incurred after eating seafood, especially raw or undercooked oysters. It can...

Vibrio cholerae is a gram negative comma-shaped bacterium with a polar flagellum that causes cholera in humans. V. cholerae belongs to the gamma subdivision of the Proteobacteria. Classical and El Tor are the two types of V. Cholerae identified by hemaggluttination testing. El Tor is found throughout the world, while the classical biotype is found only in Bangladesh. It was first isolated as the cause of cholera by Italian anatomist Filippo Pacini in 1854; however, this discovery was not...
