Conclusions
Population genetics of the gastrointestinal nematodes is a growing subject that is able to draw on the work being done on other organisms and which will benefit from collaborative sequencing projects. It is becoming increasingly clear that there is considerable information to be gained in this field that will help elucidate some of the problems associated with these infections.
The researcher now has available new methods for screening population genetic structure, using microsatellites and SNPs. New statistical approaches will allow examination of population admixture and genetic variability under selection pressure. With these methods we may be able to answer some of the questions about parasite variation, parasite advantage in the host, the evolution of parasitism and factors affecting transmission.
