Latest Vibrio cholerae Stories
YbeY is a conserved protein that is present in most bacteria.
Working with a nearly 200-year-old sample of preserved intestine, researchers at McMaster University and the University of Sydney have traced the bacterium behind a global cholera pandemic that killed millions – a version of the same bug that continues to strike vulnerable populations in the world's poorest regions.
MERS Coronavirus has been gripping the Middle East and parts of Europe for more than a year; Wild poliovirus type 1 has been on the rise in Syria after being nonexistent for more than 14 years; Mexico has seen an insurgence of infections from Vibrio cholerae O1 Ogawa in recent months.
In early September 2013, Mexico was affected by a hurricane and tropical storm that dumped heavy rain on the region, causing floods, landslides and displacement of large numbers of people. Health experts noted that the disaster could be to blame for a growing number of cholera cases affecting the region.
The strain of cholera that has sickened thousands in Haiti came from a single source and was not repeatedly introduced to the island over the past three years as some have thought.
For 50 years scientists have been unsure how the bacteria that gives humans cholera manages to resist one of our basic innate immune responses.
A team of biologists at the University of York has made an important advance in our understanding of the way cholera attacks the body.
Researchers have used next generation sequencing to trace the source and explain the spread of the latest (seventh) cholera pandemic.
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.
Researchers are focusing their attention on a computer model that would aid in predicting cholera outbreaks based on temperature increases and rainfall patterns.
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...
