Antibiotics.
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.
                                             Chronicity.
                                             Especially with respiratory agents (but not with mycoplasmas?).
  • Production inefficiencies.
                         –      Egg production.
                         –      FCR eggs and meat.
  • Dependence on antibiotics.
                         –      Prophylactic medication programmes.

Routine prophylactic programmes.
Meat.
  • Antibiotics at 20-22 days
Breeders and Layers.
  • Antibiotics in lay every 4 to 8 weeks
These are against mycoplasma Especially MS

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.

Biosecurity is one tool for control of Mycoplasma. Vaccination and treatment also required for control of Mycoplasma. Vaccination monitoring also are important.

I think Biosecurity and before vaccination I assured flock must be free from mycoplasma...?
