Having considered some of the virulence factors encoded by E. coli, take another look at Figure 1. The second-largest circle illustrates another important concept in molecular genetics ...

Virulence can be weakened by the action of different factors on the micro-organism, e. g. the defence forces of the organism, ...

An attenuated vaccine virus genetically engineered to carry the virulence mutations that the researchers identified caused paralysis in mice. “In polio, we know that viruses that are more ...

Consider this: Almost all oysters in the Gulf of Mexico are infected with a flesh-eating bacterium, Vibrio vulnificus (Hlady & Klontz, 1996). The good news? Fewer than 50 cases of V. vulnificus ...

The laboratory of Kirsten Nielsen in the Center for One Health Research has taken a step toward improved treatment of Cryptococcus, completing a six-year study to examine the virulence of 38 ...

Q: How does understanding the evolution of virulence help us to manage infectious disease? A: For most of the last two centuries people have been using interventions to knock down infectious ...

The next phase of pre-exposure prophylaxis against SARS-CoV-2 currently rests on the shoulders of a single monoclonal antibody product — but it may not be enough for immunocompromised populations.

Human fungal pathogens exemplify a severe threat to health due to their complex infection strategies and the host's immune system's failure to eradicate ...

These disruptions in calcium signaling affect rotavirus disease severity, providing new insights into how NSP4's function influences rotavirus virulence. The findings suggest that manipulating ...

This is an excerpt from an interview with Dr. Paul Ewald filmed for Evolution: "The Evolutionary Arms Race". Dr. Ewald is a professor of biology at Amherst College. His research areas include the ...
