M. hyopneumoniae antibodies in piglet blood. M. hyopneumoniae specific antibody S:P ratios were measured in piglet blood 7 days post vaccination (dpv) (panel A) and 14 dpv (panel B) using the Idexx HerdCheck™ ELISA. Piglet treatment groups are as follows: Ns Np: nonvaccinated sow, nonvaccinated piglet; Ns Vp: nonvaccinated sow, vaccinated piglet; Vs Vp: vaccinated sow, vaccinated piglet; Vs Np: vaccinated sow, nonvaccinated piglet; n = 10/group. Error bars are SEM; different subscripts represent significance at p < 0.05.
