Figure 1From: Transcriptome analysis unraveled potential mechanisms of resistance to Haemonchus contortus infection in Merino sheep populations bred for parasite resistancePrincipal component analysis (PCA) based on normalized raw counts. H: Haemonchus selection flock (HSF); T: Trichostrongylus selection flock (TSF); R: resistant line; S: susceptible line; I: innate infection protocol (primary infection); A: acquired infection protocol (repeated infection).Back to article page
