PLOS YbeY is a conserved protein that is present in most bacteria. A study published on June 5th in PLOS Pathogens examines the function of YbeY in the cholera bacterium and reveals critical roles in RNA metabolism in this and other pathogenic bacteria. Graham Walker, from the Massachusetts Institute of Technology, USA, and colleagues previously studied E. coli YbeY and found that it acts as an "RNase"—a protein that deliberately and specifically cuts RNA molecules and thereby...

Scientists Unlock Evolution Of Cholera And Identify The Strain Responsible For Early Pandemics
2014-01-09 12:57:03

McMaster University 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. Using sophisticated techniques, the team has mapped the entire genome of the elusive 19th century bacterium. The findings are significant because,...

WHO: Mexico Cholera, Syria Poliovirus, MERS Coronavirus On The Rise
2013-11-29 09:03:58

Lawrence LeBlond for redOrbit.com - Your Universe Online 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. This week the World Health Organization (WHO) has received three separate reports from health officials in Saudi Arabia, Mexico and Syria pertaining...

Cholera Outbreak Gripping Mexico, 171 Confirmed Cases
2013-10-21 06:41:53

Lawrence LeBlond for redOrbit.com - Your Universe Online Last month, 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 may have contributed to the growing number of cholera cases that are now also affecting the region, which first became evident around the second week of September. Mexico’s Ministry of Health has reported a total of...

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, according to a new study published in mBio®, the online open-access journal of the American Society for Microbiology. The results of this latest study are consistent with earlier findings that indicate Vibrio cholerae bacteria were introduced to Haiti by United nations soldiers between July and...

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,...

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...
