Fig. 2From: MicroRNA expression profiles of bovine milk exosomes in response to Staphylococcus aureus infectionPrincipal component analysis of mapped reads by animal. Principal component analysis of the mapped sequence reads matching known bovine miRNAs from the eight individual libraries. Control represents sequences from non-infected milk exosome libraries and Infection represents those from infected quarters of the same animals 48Â h post-infectionBack to article page
