  • viral virulence
  • Some viral virulence factors confer ability to replicate during the defensive inflammation responses of the host such as during virus-induced fever. (wikipedia.org)
  • In wild rabbits, the combination of host resistance and increased viral virulence resulted in typical myxomatosis presentation, but when naive rabbits were exposed to the new viral strains, bacterial infections bloomed in their immunosuppressed bodies, killing nearly all of the hosts before they developed the classic disease. (the-scientist.com)
  • Findings of increased viral virulence in selenium-deficient hosts support the need for further investigation into the interaction between host nutrition and viral evolutionary processes. (wikipedia.org)
  • host
  • Virulence is a pathogen or microbe's ability to infect or damage a host. (wikipedia.org)
  • In most other contexts, especially in animal systems, virulence refers to the degree of damage caused by a microbe to its host. (wikipedia.org)
  • However, the host, being the parasite's resource and habitat in a way, suffers from this higher virulence. (wikipedia.org)
  • These three models help to explain the life history strategies of parasites, including reproduction, migration within the host, virulence, etc. (wikipedia.org)
  • 2004) studied the malaria parasite using a rodent and chicken model respectively and found that there was trade-off between transmission success and virulence as defined by host mortality. (wikipedia.org)
  • The same mutations that enhance the reproduction and dispersal of the pathogen also enhance its virulence in the host, causing much harm (disease and death). (wikipedia.org)
  • immune
  • We could give anti-virulence antibiotics to people with healthy immune systems, who would be able to clear infections with this assistance," he said, "and traditional antibiotics combined with antivirulence therapies to people with compromised immune systems, who really need them.

  • contributes
  • Proton motive force (PMF), a consequence of metabolic activity, also contributes to the regulation of bacterial virulence, and the addition of proline to the medium allowed P. luminescens to form colonies in the presence of drugs that disrupted PMF, suggesting that proline oxidation may provide an electron source for generation of PMF.

  • isolates
  • To address their hypothesis, the authors inoculate vaccinated or unvaccinated chickens with a series of MDV isolates that range from low to high virulence. (virology.ws)
  • tends
  • He came to the conclusion that virulence tends to remain especially high in waterborne and vector-borne infections, such as cholera and Dengue. (wikipedia.org)
  • disease
  • The virulence of MDV has been increasing since the 1950s, initially from a paralytic disease, to paralysis and death. (virology.ws)
