B155 - CONTAGIOUS CAPRINE PLEUROPNEUMONIA

B155 - CONTAGIOUS CAPRINE PLEUROPNEUMONIA
Nature of the disease |
Contagious caprine pleuropneumonia (CCPP) is a contagious disease caused by Mycoplasma capricolum sub-speciae capripneumoniae that causes severe fibrinous pleuropneumonia of goats characterised by respiratory distress, coughing, nasal discharge and high mortality rate. |
Classification |
OIE List B disease |
Susceptible species |
CCPP only occurs in goats. |
Distribution |
CCPP occurs throughout most of Africa, the Middle East, India and Pakistan. |
Clinical signs |
Peracute and acute forms of the disease occur when it
is introduced into fully susceptible flocks. Chronic cases occur in endemically
affected areas.
Peracute form Acute form
Chronic form |
Post-mortem findings |
In acute cases there is:
With chronic cases lungs will be in various stages of resolution with encapsulation of acute lesions and numerous fibrous adhesions. |
Differential diagnosis |

Specimens required for diagnosis |
At post-mortem, exudate fluid should be collected from
lung lesions together with pleuritic fluid. Duplicate specimens of active lung lesions — one set should be submitted fresh, the other collected into neutral buffered formalin for histopathology. Blood samples (10 ml) should be collected from several animals in the affected flock for serology. |
Transmission |
CCPP is highly contagious. It is transmitted via the respiratory route and is spread by close contact between goats. Unlike contagious bovine pleuropneumonia, chronic carriers are not as important. CCPP spreads to new areas by the movement of infected goats. |
Risk of introduction |
CCPP is most likely to be introduced to a previously free country by the introduction of infected goats. |
Control / vaccines |
Where an outbreak occurs in a previously free
country, eradication should be attempted by slaughter of all infected and
in-contact goats, and the implementation of quarantine and movement controls.
Antimicrobial agents such as tylosin, terramycin or streptomycin can be used
to treat clinical cases. |
