Presentation Transcript

  1. CONTAGIOUS BOVINE PLEUROPNEUMONIA (CBPP)

  2. Mycoplasma mycoides subspecies mycoides SC (bovine biotype). • subacute or symptomless infections • persistence of chronic carriers after the clinical phase • incubation period: 6 months

  3. Diagnosis: • clinical signs in the live animals (problem: may be slight or non-consistent; asymptomatic carriers) • gross pathological findings (lesions are characteristic but not always obvious) • serological tests culture and identification of the causative organism (difficult if anti-microbial treatment) • PCR • effective meat inspection + laboratory examinations of suspect lesions

  4. provisional freedom from disease + 2 years • freedom from disease + 2 years • freedom from infection

  5. Specific criteria: • no clinical or pathological evidence of CBPP (for the declaration of provisional freedom: at least for 3 years or 1 year if no vaccination); • effective veterinary service; • effective meat inspection; • all evidence suggestive of CBPP is investigated by laboratory methods; diagnostic procedures capable of differentiating Mycoplasma mycoides from other bovine Mycoplasma infections;

  6. effective reporting system; • effective system to prevent the introduction of infection (e.g. border control, quarantine); • if vaccination has been used, all vaccination against CBPP has ceased by the date of declaration of provisional freedom.

  7. Country free from infection without intermediate steps • continuously free from CBPP for at least 10 years and • no vaccination for at least 10 years; • no clinical or pathological evidence for at least 10 years; • adequate disease surveillance and reporting system; • use of diagnostic procedures capable of differentiating Mycoplasma mycoides from other bovine Mycoplasma infections

  8. localized temporary outbreak: stamping-out policy, which may be supported by zonal vaccination. re-establishin infection free status: • 2 years from the date of the last case; • demonstration that the outbreak did not represent endemic infection and that the disease has been eradicated by the actions taken
