We have been examining vaccinated flocks by DIVA PCR and culture recently in Asia. Here we can not find the MG and MS live vaccines in flocks that have had anti-mycoplasmal antibiotics. We typically find field strains (we suspect they are resistant to antibiotics). The vaccine strains are sensitive to all anti-mycoplasmal antibiotics (even quinolones like enrofloxacin) even if local field strains ...

Ganesh Kumar Dahal I am just in Argentina and one vet is telling me how all antibiotics had stopped working on one client's farm and he was able to get control of mycoplasma again by vaccination. Remember not to forget MS as well as MG

Vaccination in an infected environmentAll vaccines take a little while for the onset of useful immunity (save non specific protection from mechanisms like gamma interferon in viral infections). Mareks vaccination becomes more effective with the current vaccines if challenge can be delayed a couple of weeks.Live Mycoplasma vaccines also take 3-5 weeks to generate immunity and challenge needs to be ...

Other myths are emerging.1) ts-11 only works to 40 weeks (of age or after vaccination). This is a misunderstanding of the seroconversion that often takes place after the peak of lay in vaccinated flocks. Studies on these flocks don't find wild strains and there is no production problems or clinical signs. They only thing they seem to be suffering is antibiotic deficiency syndrome. See Barbour et a ...

INTRODUCTION The simplest approach to decrease dependence on routine antibiotic regimes in animal production is to implement alternative methods to control the bacterial challenges that the antibiotics are modulating (and not look at antibiotics as non-specific production enhancers). The chronic nature of mycoplasma infections and vertical transmission in poultry are the reasons for the strategy ...

Amod Saru Magar you could have antibiotic resistant strains - we are currently collecting these by a new culture technique in Asia Chris.morrow@bioproperties.com.au

1) Mycoplasma synoviae (MS) does nothing. 2) MS does not have airborne spread. 3) It is not MS because there is no joint involvement. 4) You must use F strain in the first stage of eradicating MG. That MS does nothing is an interesting view. There is great variation in the potential of MS strains to cause disease but avian Mycoplasma experts worldwide agree that MS is a pathogen, it has its ow ...

It is frustrating and disappointing how we veterinarians, flock and farm managers, farm owners abuse and overlook the antibiotic resistance on today's world. We're already living an post antibiotic era. But the vast majority of those involved in food chain, in some countries, still do not realize it. Some comments above are the testimony of this.

I have been to India quite a bit lately and control also includes combinations of live and killed vaccines, biosecurity and antibiotics. The availability of mycoplasma free replacement stock is also a new innovation and requires a complete rethink of mycoplasma control in India. I also saw a lot of flocks still having mycoplasma problems despite being treated regularly with antibiotics even with T ...
