Scientists have figured out how cholera bugs invade our guts infecting millions and killing more than 100000 people worldwide every year reveals a study. The discovery potentially paves the way for more effective treatments against the bug Vibrio cholerae which is able to colonise the gut after consumption of contaminated water or food. The bug secretes a toxin that causes watery diarrhoea and ultimately death if not treated rapidly the Journal of Biological Chemistry reported. Colonisation of the intestine is difficult for incoming bugs as they have to compete to gain a foothold among the trillions of other bacteria already
