The vaccines have different kinetics with serology and PCR
MSH tends to increase in pan species PCR to 100% about 8 weeks post vaccination and stay high for the life of the bird. DIVA PCRs are less sensitive than pan species PCRs in general.
ts-11 initially increases in pan MG PCRs to about 4 week post vaccination peaking at 40% and then decrease again to rise as the birds come into lay and pea ...

I agree the best way to work such a problem is to vaccinate against M.synoviae and M.gallisepticum at 4-5 wks of age,chek the chix they have to be clean from mycoplamas before vaccination and avoid the use of antibiotics against mycoplasmas..The ts11for Mg and vax safe for synoviae are vaccines that work fine.
