Variation in gut bacterial composition is associated with Haemonchus contortus parasite infection of sheep

Background One of the greatest impediments to global small ruminant production is infection with the gastrointestinal parasite, Haemonchus contortus . In recent years there has been considerable interest in the gut microbiota and its impact on health. Relatively little is known about interactions between the gut microbiota and gastrointestinal tract pathogens in sheep. Thus, this study was undertaken to investigate the link between the faecal...
