Cholera is a severe diarrheal illness caused by a Vibrio cholerae bacterial infection of the intestine.A recent study explains why a highly contagious cholera bug variant that caused significant disease outbreaks in the early 1990s did not, according to expectations, create the eighth cholera pandemic. Instead, it mysteriously vanished.
The cholera bug is not currently being closely monitored. In order to stay ahead of the cholera bug as it evolves, scientists believe continuous monitoring of the genes responsible for AMR and toxin production is necessary. This will particularly help with the planning of vaccine improvements and suitable public health measures to stop cholera outbreaks in the future.
Cholera is a life-threatening infectious disease, usually caught by eating or drinking contaminated food or water. It only causes large outbreaks in places where hygiene and sanitation are poor, so it is primarily restricted to the developing world. The new study analyzed 330 samples of the cholera variant O139, taken between 1992 and 2015, to reveal two key changes in its genome that may have been the cause of its decline over three overlapping waves of disease transmission.

The Chair of Illycaffè on Creating Virtuous Agricultural EcosystemsIn the 1990s most coffee beans were still commodity products, cheaply priced, undifferentiated by quality, often blended, and sold through an exchange. Suppliers were underpaid not only because they sat at the bottom of the value chain but also because margins were very thin. Francesco Illy founded his eponymous coffee company in 1933 with higher ambitions, intending to create an institution respected for both its products and its contributions to society. His son, Ernesto, and grandson, Andrea, pressed on in that tradition—first by implementing better quality-management systems and pioneering direct trade with growers, and then by adopting their new production model at scale. The idea was to incentivize farmers to cultivate more-flavorful beans, thereby generating bigger profits to be shared among all stakeholders and reinvested in further improvement and growth: a virtuous circle of increasing returns. Over the past two decades illy has been accomplishing what it set out to do. Its annual revenue is currently €500 million, with earnings before interest, taxes, and depreciation of nearly €60 million and a compound annual growth rate of 10%. And it pays its growers an average of 30% more than market price for coffee beans and is consistently recognized as one of the world’s most socially responsible companies.
