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?

Both vaccines live and killed

I would be grateful if somebody tell me if I have an infected flock sub-clinically with AI 1- Is it possible to get Elisa false negative result if Elisa was conducted 2-if I repeat Elisa after 2-3 weeks what is the expected titre to get. Thanks.

Respected Dr Hisham greetings Deeply sorry for that mistake I mean weak immunity that is to say the mean titre of IB is spare in amount Compare to that of ND

Dear Dr. Husam, how could you explain the week immunity of IB whenever I used the combination of live Ma5 and clone 30 vaccine in my parent breeder?

Can the Mg ts-11 vaccine cross-protect against mycoplasma synoviae?

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?
