How bugs overcome host defenses

Bacterial pathogens must acquire nutrient metals from the host to survive and cause disease. To counter infection, hosts attempt to starve bacteria by hiding metals away in a process called "nutritional immunity." Bacteria ...

Research identifies potential target for strep A vaccine

Most people think of "strep throat" as a relatively benign infection cured by a round of antibiotics and a few days of rest. But the bacterium that causes strep throat—Group A Streptococcus—is also responsible for a number ...

Research advances search for new antibiotics

Indiana University researchers are advancing knowledge about how bacteria build their cell walls that could contribute to the search for new antibacterial drugs. They have created a new tool to observe living cells in real ...

Scientists create multifunctional protein-polymer films

A team from MSU, with international and Russian colleagues, has found that mixing dendrimers (tree-like polymers) and proteins induces spontaneous multilayer films. They are easily formed and retain the activity and function ...

Microbial resident enables beetles to feed on a leafy diet

An international team including researchers from the Max Planck Institute for Chemical Ecology has described a bacterium residing in a species of leaf beetles which has an unexpected feature: it provides the beetle with the ...

Using neutrons to study how resistant bacteria evolve

The discovery of penicillin almost 90 years ago ushered in the age of modern antibiotics, but the growth of antibiotic resistance means bacterial infections like pneumonia and tuberculosis are becoming more difficult to treat.
