Cholera strain becomes unexpectedly resistant to infection by phages

Graduate student Kristen LeGault and assistant professor Kimberley Seed, both in the Department of Plant and Microbial Biology, specialize in the evolution of human pathogens and the viruses that infect bacteria, known as ...

Mechanical forces of biofilms could play role in infections

The vast majority of bacteria in the world live on surfaces by forming structures called biofilms. These communities host thousands to millions of bacteria of different types, and are so biologically complex and active that ...

Microbiome confers resistance to cholera

Cholera can kill within hours if left untreated, and it sickens as many as 4 million people a year. In a new article in the journal Cell, researchers describe how gut bacteria helps people resist the disease.

Evolution of bacterial movement revealed

An international team with researchers from Leiden revealed how a bacterium repurposed an internal system to control its movements. Movement control is very important in host invasion, which can lead to disease. Publication ...

The cholera bacterium can steal up to 150 genes in one go

EPFL scientists have discovered that predatory bacteria like the cholera pathogen can steal up to 150 genes in one go from their neighbors. The study sheds light on one of the most fundamental mechanisms of horizontal gene ...

Protozoans and pathogens make for an infectious mix

Single celled organisms in the environment are protecting pathogenic bacteria and priming them for human infection, an international team of researchers has discovered.

The cholera bacterium's 3-in-1 toolkit for life in the ocean

Bacteria are the most abundant form of life on Earth. The ocean is highly abundant with small particles and debris, some inert, some highly nutritious. But researchers want to know how bacteria differentiate between these ...
