Will affect mycoplasma vaccine. 

  • Enrofloxacin
  • Tetracyclines
  • Macrolides
  • Lincomycin
  • Tylosin
  • Tiamulin
  • Timiclocin
  • Sulpha etc (a little)
  • Chloramphenicol

May not affect local field strains; Acquired resistance.


Won’t affect vaccine.

  • Ampicillin
  • Amoxycillin
  • Penicillin
  • Fosfomycin (Phosphomycin)
  • Cephalosporins
  • Not absorbed orally

                      –      Spectinomycin
                      –      Neomycin

  • Colistin and antibiotics at growth promoter levels


Effects of avian mycoplasma infections.

  • Overt disease.

                         –      Primary effects.
                         –      Synergistic effects.

                                             Especially with respiratory agents (but not with mycoplasmas?).

  • Production inefficiencies.

                         –      Egg production.
                         –      FCR eggs and meat.

  • Dependence on antibiotics.

                         –      Prophylactic medication programmes.









Chronic Respiratory Disease Three way is the most severe.


Mycoplasma control strategies.


Routine prophylactic programmes.


  • Antibiotics at 20-22 days


Breeders and Layers.

  • Antibiotics in lay every 4 to 8 weeks


These are against mycoplasma Especially MS

Antibiotic reduction: Case studies with MSH.


Indonesian case study Broiler breeders.


Cost-benefit analysis (USD).


Estimate of antibiotic use against MS in Europe (2011).

Mycoplasma freedom.

  • Achilles heel

                        –      Totally susceptible populations

                                          Unprotected except by biosecurity
                                          Surrounding reservoirs are not always also trying to control (Type of compartmentalization).

  • Vaccination

                        –      Increase resistance to getting infected

                                          Need update of OIE/NPIP etc


Non vaccinated flock with 2 egg production drops responsive to Tylosin.


Vaxsafe® MSH and MG ts-11 vaccinated responding to amoxicillin.
