Latest Vibrio cholerae Stories

The answers may help clear the way for a new class of antibiotics For 50 years scientists have been unsure how the bacteria that gives humans cholera manages to resist one of our basic innate immune responses. That mystery has now been solved, thanks to research from biologists at The University of Texas at Austin. The answers may help clear the way for a new class of antibiotics that don't directly shut down pathogenic bacteria such as V. cholerae, but instead disable their defenses so...

A team of biologists at the University of York has made an important advance in our understanding of the way cholera attacks the body. The discovery could help scientists target treatments for the globally significant intestinal disease which kills more than 100,000 people every year. The disease is caused by the bacterium Vibrio cholerae, which is able to colonise the intestine usually after consumption of contaminated water or food. Once infection is established, the bacterium secretes a...

Researchers have tracked the spread of antibiotic resistant strains back to the Bay of Bengal Researchers have used next generation sequencing to trace the source and explain the spread of the latest (seventh) cholera pandemic. They have also highlighted the impact of the acquisition of resistance to antibiotics on shaping outbreaks and show resistance was first acquired around 1982. Whole genome sequencing reveals that the particular cholera type responsible for the current pandemic...

Lessons from 2001 anthrax case help pinpoint source of disease Employing technology that reads the entire DNA code, researchers led by the Translational Genomics Research Institute (TGen) and the Technical University of Denmark (DTU) have pinpointed the source of a cholera outbreak in Haiti that killed more than 6,000 people and sickened 300,000. Using whole genome sequencing, which spells out the billions of chemical bases in DNA, TGen and DTU provided the strongest evidence yet that...

Researchers are focusing their attention on a computer model that would aid in predicting cholera outbreaks based on temperature increases and rainfall patterns. Cholera is a potentially lethal diarrhea-causing bacteria that affects vulnerable populations, often without warning.Scientists at the International Vaccine Institute in Seoul, South Korea, analyzed several years of past data in cholera-prone parts of Zanzibar, Tanzania, showing that when temperatures rose one degree Celsius, cholera...

Just over a year after the earthquake in Haiti killed 222,000 people there's a new problem that is killing Haitians. A cholera outbreak has doctors in the area scrambling and the water-borne illness has already claimed 3600 lives according to officials with Médicin Sans Frontières (Doctors without Borders).Stefan Pukatzki, a bacteriologist in the Faculty of Medicine & Dentistry at the University of Alberta, is hoping that down the road he can help prevent deadly cholera...

New clinical strains of cholera appear to have evolved a distinctly different mechanism to cause the same disease according to research published in the current issue of the online journal mBio®.Vibrio cholerae is the causative agent for the diarrheal disease cholera. While there are more than 200 different serogroups only the O1 and the O139 strains have been known to cause epidemic and pandemic outbreaks of disease, using a toxin-coregulated pilus (TCP) and cholera toxin (CT), which...

GFS BioProtectâ„¢ Effluent Remediator (BPER) utilizes revolutionary new biotechnology to remove odour, breakdown waste, and kill Vibrio Cholerae in camp latrines. Brisbane, Australia (PRWEB) November 30, 2010 Global Future Solutions (GFS) announced today that its non-toxic waste treatment products GFS BioProtectâ„¢ Effluent Remediator (BPER) and GFS BioProtectâ„¢ Industrial Cleaner (BPIC) have been independently proven to kill the cholera strain responsible for the outbreak...

Haiti cholera epidemic is spreading quickly and could easily worsen despite efforts to control it. As concerns rise over massive health challenges, Dr. Dalmacy outlines steps every Haitian and every health provider caring for cholera victims should take to stay alive, save lives and prevent further spread of the disease. Brooklyn, NY (PRWEB) November 19, 2010 Early in October 2010, a number of Cholera cases were reported in localities of Haiti's Central and Artibonite regional...

HOFFMAN ESTATES, Ill., Nov. 12, 2010 /PRNewswire-USNewswire/ -- Hurricane Tomas has complicated the already difficult sanitary and living conditions of the Haitian people. The results of the flooding have caused a high spike in the number of cases of Cholera. The death toll is over 800 and rising, with 11,215 reported cases, according to the Haitian Health Ministry's website. Bright Hope has access to immediate aid to help with this urgent health situation in affected regions we serve....
