Pathogenicity and virulence

Journal of Invertebrate Pathology, 2004
Invertebrate pathologists have multiple definitions for the terms pathogenicity and virulence, and these definitions vary across disciplines that focus on host-pathogen interactions. We surveyed various literatures, including plant pathology, invertebrate pathology, evolutionary biology, and medicine, and found most define pathogenicity as the broader ...

Virulence of nocardiae

Canadian Journal of Microbiology, 1973
The virulence of Nocardia brasiliensis, N. asteroides, and N. caviae was investigated. The study was done by inoculation of these organisms into the footpad of white mice. The results show that N. brasiliensis has greater virulence than N. asteroides and N. caviae. These observations resemble clinical findings in which N.

The ecology of virulence

Ecology Letters, 2006
AbstractTheoretical work has shown that parasites should evolve intermediate levels of virulence. Less attention has been given to the ecology of virulence. Here I explore population‐dynamic models of infection in an annual host. The infection does not kill the host; but it can decrease the number of offspring produced by the host, and the magnitude of

The evolution of virulence

Trends in Microbiology, 1994
Why is there variation in the virulence of infectious diseases? Virulence can have substantial effects on the genetic contribution of both host and pathogen to future generations. Understanding it therefore requires explanation not only in terms of cellular and molecular mechanisms, but also in evolutionary terms: what is the nature of the selection ...

Virulence and pathogenesis

Trends in Microbiology, 2002
Why do viruses cause disease? As intracellular parasites they grow at the expense of the host, yet many infections are non-virulent. We tend to focus on unusual outcomes of infection that are important to the individual but trivial for host-parasite evolution, for example, paralytic polio or viral cancer.

HIV Virulence

Nursing Standard, 1988
The virulence of human immunodeficiency virus may increase in the later stages of the disease, which might explain why people go on to get full blown AIDS.
