Hello Mr. Chris Morrow I have used the MG Ts 11 vaccine for a long time, based on the results of the Elisa Test before 2019 the average mean titters is between 1000-4000, but starting in 2020 with the use of the MG TS 11 vaccine as well, but different batch numbers now result in titter between 100 - <1000 in the Elisa sample aged 28 weeks. Please explain it why this happened. Whether there is ...

My experience of a few years - working in the diagnosis, prevention and control of avian mycoplasmosis in industrial poultry - shows me that: 1) Vaccines and treatments for MG were not made to be applied in the broiler production pyramid; you're either free, or you're out. 2) Acquiring birds free of MG and MS and applying heavy biosecurity rules is a key point to control the problem in this chain. ...

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 ...
