None Provided49 Parasites and their Virulence By: Terry ABSTRACT hence do some parasites kill the army they depend upon musical theater composition others coexist with their host? Two prime factors stipulate parasitic virulence: the manner in which the parasite is transmitted, and the evolutionary narrative of the parasite and its host. Parasites which nurture colonized a radical host species tend to be more than virulent than parasites which have coevolved with their hosts. Parasites which be transmitted horizontally tend to be more virulent than those transmitted vertically.
It has been assumed that parasite-host interactions inevitably evolve toward demoralise virulence. This is contradicted by studies in which virulence is conserved or increases all over time. A model which encompasses the variability of parasite-host interactions by synthesizing spatial (transmission) and laic (evolutionary) factors is examined. Lenski and whitethorn (1994) and Antia et al. (1993) predict the modulation of vi...If you want to get a fully essay, order it on our website:
