The type III secretion system (T3SS) is a sophisticated molecular apparatus that many Gram‐negative bacterial pathogens deploy to inject effector proteins directly into host cells. This machinery ...

Antibiotic resistance is a major concern, particularly for immunocompromised patients, who are at greater risk of serious infections. Microbiota composition can help prevent pathogenic bacteria from ...

Viruses and bacteria are not responsible for all infections diseases. Many infectious diseases are caused by viruses and bacteria. But there are also other types of pathogens that cause illness.

In many cases, the fundamental differences between harmless microbes and those that are considered to be harmful, i.e., common pathogenic, can be attributed to genes encoded on mobile elements such as ...

Most bacterial gastrointestinal illnesses in Australia are thought to be caused by two pathogens, Campylobacter and Salmonella. But an emerging pathogen, Aeromonas, is much more common than previously ...

In Brazil, a group of researchers supported by FAPESP created mutant forms of Salmonella to understand the mechanisms that favor colonization of the intestinal tract of chickens by these pathogenic ...

Viruses attack nearly every living organism on Earth. To do so, they rely on highly specialized proteins that recognize and bind to receptors on the surface of target cells, a molecular arms race that ...
