Isolation and Antimicrobial Sensitivity of Mycoplasma synoviae and Mycoplasma gallisepticum from Vaccinated Hens in Mexico

Good article on mycoplasma. In India, our experience is Yes MS is more prevalent compared to M.G. TYLOSINE on regular medication and tiamutin monthly program is controlling the infection as indicated by clinical cases and production losses. Rearing chicks on separate sites and following all in all out housing with good biosecurity is working. Regular serological monitoring showed that the birds are turning positive after the productions reach peak. Presence of m.s is more. I personally feel M.S is causing less losses individually. The production losses are more serious when the flocks turn positive for M G also. Live vaccines at early age without medication is not proving to be foolproof as in the case of viral diseases. Reversal of virulence of Live strains is possible but we have no study. Phytogens like turmeric and their dosage is yet to be proved. These observation are based on our production data at various units. Not based on laboratory study. We are watching the results of recombinant POX+M.Gvaccine. The initial results are encouraging. Flocks that get exposed earlier ( in growing) have less production losses. Of course with tylosine+ tiamulin treatment.
