Wael Elfeil Thanks for useful discussion I totally agree with you about when we use homologous vaccine against field strain ,they will induce good protection such as if we have Middle East strain we can use Var -2 vaccine but if we we have many serotype in field situation such as var-2 and QX I advice use protecotype theory to induce cross protection against other serotype Kindly if you have te ...

Well, I think that killed avian mycoplasma vaccines make humoral antibody. In fact, to get registration, they only have to show production of antibody - from the monograph. It is just sort of assumed that it is correlated with protection. So I agree that they can decrease systemic pathology, tracheal populations, vertical transmission but they don't seem to be able to stop infection or vertical tr ...

Wijaya Saputra Serology is useless after live vaccination (and probably killed MG vaccination). There are too many normal responses and perhaps these are modulated by factors other than mycoplasma - like using LaSota. http://www.bioproperties.com.au/!Pages/Publications/Documents/DOC-Bulletin-2015-02.pdf See the bulletin. But in Australia nearly all broiler breeders have no serological response ...

Hany Ellakany killed or bactrin MG vaccine can administrated s/c or IM Induce humoral immunity reduce the decline eggs production dont prevent infection due to killed not induce CMI which very important for protection cant displace field strain decrease vertical transmission rate so in my opinion the best practice for protection against MG is Combination killed and live vaccine in high cha ...

Hany Ellakany thanks prof. Dr Hany for your discussion I will share my knowledge in our situation in Saudi Arabia , you know Saudi Arabia is big country and the distance between region and poultry project is very far and bio security procedure is better than applied in Egypt so the discussion according three point related three MG live vaccine 1- lateral transmission 2- vertical or eggs trans ...

Mustafa Ezat Dear Dr. MostafaThank you for your participation Do you think the vaccines of mycoplasma could be used in separate projects other than the whole country? I mean is it possible to be used on small scale rather than the whole nation? Especially if there is a lack of good and strict biosecurity?

Mustafa Ezat Dear DR mustafa greeting combination of Vector ND with Inactivated ND, results varies based on the epidemiological situation in each area and type of production in broiler , you can use vector ND instead of one-day old inactivated ND then use inactivated at 7-9-day of life together with 2-3 live ND in endemic areas in layers flocks, can use vector ND and it will be add value to the ...
