- 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.
– 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.
Airsacculitis.
Synergy.
Factors.
Chronic Respiratory Disease Three way is the most severe.
Mycoplasma control strategies.
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
Antibiotic reduction: Case studies with MSH.
Indonesian case study Broiler breeders.
Cost-benefit analysis (USD).
Estimate of antibiotic use against MS in Europe (2011).
Estimate of antibiotic use against MS in Europe (2011).
Case report: flock 2011.
Mycoplasma freedom.
– Totally susceptible populations
Unprotected except by biosecurity
Surrounding reservoirs are not always also trying to control (Type of compartmentalization).
– 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.
