While the lesion site infection samples (i.e. Mv-At) associated with the left side vectors such as crem, irf7, tlr5, csf1r1 and ch25ha as well as the M. viscosa transcripts (i.e. glyA, rpoB, rtxA and gyrB), samples from the other groups (i.e. Mv-Aw, Mv-N and Control) were associated with the right side vectors (e.g. tapbp, ccl20 and atf2). The gene discussed is CREM; the disease is infection.
