I would be grateful if somebody can explain why mycoplasma maternal antibody titre is always negative in day-old chick from vaccinated parent breeder when tested by Elisa? Why do day-old chicks tested for mycoplasma maternal antibody at 3 week old with Elisa and why does that happen with mycoplasma and not another respiratory disease?

I am looking for standard protocol for isolation of clostridium perfringens from necrotic enteritis in chickens. Is the enrichment step necessary for isolation? What is the most efficient enrichment broth that I could use? I had observed in some articles I read that they subject the test sample in anerobic broth to heat shock prior incubation. Why do they do that?
