Home Livestock & Diseases Livestock diseases Contagious Bovine Pleuropneumonia
Contagious Bovine Pleuropneumonia (CBPP) is an important respiratory disease affecting cows and other ruminants in Africa.

Causative agent

It is caused by bacteria Mycoplasma mycoides mycoides, small-colony type (SC).

Geography

CBPP is endemic in Africa in areas between the Tropic of Cancer and the Tropic of Capricorn.

Impact

CBPP can cause loses from 20% to up to 80%. Morbidity and mortality vary between different pathogen strains. The total yearly cost of the disease is estimated to be US $634 million.

Epidemiology

Infection spreads by aerosol from cough, by direct contact with infected animals, or through placenta to the unborn calf. Fomites are not a major source of transmission.

Clinical signs

The incubation period is one to three months. A few cattle may die of peracute disease with no symptoms other than fever. Acute symptoms include fever, lethargy, cough, extended necks and laboured breathing, and loss of appetite and milk production. Calves may develop arthritis and lameness. After initial acute faze, the infection often becomes chronic.

Control

Outbreaks are eradicated with quarantines, slaughter of infected and in-contact animals, and cleaning and disinfection. Vaccines are available and have helped to control the disease in endemic areas.
