Fig. 2From: Effect of maternal separation and transportation stress on the bovine upper respiratory tract microbiome and the immune response to resident opportunistic pathogensSerum antibody responses to M. haemolytica and P. multocida in suckling calves and in calves following weaning and transportation stress. Antibody titres to M. haemolytica were measured using both a recombinant leukotoxin (Lkt) protein (A) and soluble bacterial lysate (B). Antibody titres to P. multocida were measured using soluble bacterial lysate (C). Antibody titers to recombinant My. bovis MilA-ab (D). Significant differences were observed in antibody titres on Day 28 for M. haemolytica and P. multocida, when comparing among the three treatment groups (Suckling calves, Weaned calves, and Weaned + Transport calves) and these differences are indicated by letters (a,b,c). Data presented are the mean and 1 SDBack to article page
