Introduction
• CBPP is an infectious disease of cattle which has a huge
impact on the society.
• CBPP is caused by Mycoplasma mycoides subspecies
mycoides Small Colony variant (MmmSC).
• The organism produces natural infection in cattle and water
buffaloes (Bubalu babulus), but not in wild buffaloes
(Syncerus caffer).
• CBPP is widespread in Africa and it is recognized to be
present in some countries of Asia and Europe.

Introduction
• In Africa, it is found in an area south of the Sahara, from the Tropic
of Cancer to Tropic of Capricorn and from Atlantic to the Indian
Ocean.
• Endemic infection extends throughout the pastoral herds of much
of western, central and eastern Africa, with Angola and northern
Namibia in southern Africa.

Conclusions
• Slaughter of clinical cases of CBPP is not beneficial to pastoralists
• Treatment of clinical cases, annual vaccination and a combination
of these two strategies have benefits to pastoralists
• Vaccination services against CBPP can be delivered through signed
contractual agreements between private and public veterinary
departments
