Abdulcader titres often increase after 40 weeks and can be very high in normal flocks. The only way to investigate if this is 1) Normal - just high titres after 40 weeks or 2) Field challenge (from a variety of reasons, post vaccination antibiotics, infection before vaccination etc) then you should find field strain. So you need DIVA PCR - it will detect field strain if that is the problem ...

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 ...

Want to know more about MS and MG vaccination as an alternative to antibiotics.!Pages/Publications/Documents/DOC-Bulletin-2020-01.pdf cheers chris

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.!Pages/Publications/Documents/DOC-Bulletin-2015-02.pdf See the bulletin. But in Australia nearly all broiler breeders have no serological response ...

David Baquero we have to stop using antibiotics every 4-6 weeks for human health reasons. In the short and maybe medium term it is effective but it may mean the loss of effectiveness of antibiotics for treating ordinary infections in the long term: it is expensive.

Sachin Patil Actually F strain is regularly vertically transmitted (it probably stops vertical transmission of field strains as you said). Most studies come up with a figure of about 1:120 chicks from vaccinated flocks are infected with F strain from vaccination. And this can cause clinical problems in the progeny. This can be prevented by using antibiotic programs. AS you said it is mild. It ...

Eric Gingerich your comments about MS are certainly the current view in the USA (in states without turkeys) but I think MS is causing more subtle losses in the US egg industry. F strain and MS in the US avain respiratory background are not causing clinical problems unlike many other places in thre world (TRT, respiratory virus control etc). But sublinically? Certainly F strain in the US was esti ...

Eric Gingerich thank you. I should emphasis that phasing out mycoplasma antibiotic prophylaxis is at different stages around the world and also varies in countries between table egg production and broiler meat production. So Australia is probably the most advanced from having the mycoplasma vaccines (including MS) over 25 years, The US, Argentina and UK especially poultry meat production are v ...

PHONGTHEP MORAWAN mycoplasma freedom is only possible when you have goood underlying biosecurity - this includes farm siteing and isolation - very difficult in the short term (but some gains can be made in the medium term with rearing away from multiage sites. Live mycoplasma vaccination is the other way of controlling mycoplasma infections. Simply you need the same strategy for MG and MS. No us ...
