"host competition" is correct and grammatically usable in written English.
You can use it to refer to an event where a person or group organizes a competition or challenge. For example, "The company is hosting a competition to find the best new video game designer."
Watch out, Tyra!" This time, Barker gets to sit back and leave the judging to others, but that doesn't mean he's not up for some friendly host competition with his former boss.
Parasite prevalence depends on host competition and predation, and parasite-induced mortality (figure 1).
Indeed, within host competition among genotypes can either increase or decrease immediate virulence and is also a major driver of virulence evolution (Mideo 2009).
When parasites share a host, competition for the limited resources is generally expected to favour the most aggressive parasite – the tragedy of the commons [ 16].
Parasites have many other ecological implications in phenomena such as parasite mediated host competition [ 5], sex and sexual selection [ 6- 10] social behaviour including xenophobia and sexual fidelity [ 11], foraging strategies [ 12, 13] and predator prey dynamics [ 14, 15].
The copy number and family diversity in a given genome result from the interactions between the rate of transposition, the control of transposition by the host, competition between families of elements for host-encoded resources, the intensity of selection against new inserts, and the demographic history of populations.
Preliminary experiments have used a Plasmodium chabaudi rodent malaria model, previously used to study aspects of mixed genotype infections, such as the dynamics of multiple infection, 25 within-host competition in genetically diverse infections, 26 and competitive release of drug resistance on drug treatment in mixed infections.
Within this nested framework, we show that the virion production rate at the level of the cell virus interaction leads, via within-host competition, to the presence or absence of between-host level competitive exclusion.
These results substantially advance upon previous studies that investigated within-host competition between Microbotryum genotypes [ 16, 17] by suggesting that competitive antagonism between coinfecting strains increases with genetic distance, not only at intra-specific levels of relatedness, but also to encompass between-species interactions.
Here we propose a novel approach to study the interplay between within- and between-host competition.
The model allows for multiple genotype infections, encapsulating a form of within-host competition that gives selective advantage to parasites expressing more dominant VSAs [27].
