« Peste des petits ruminants »(PPR) is also known as pseudorinderpest of small ruminants, pest of small ruminants, goat plague, pest of sheep and goats, Kata, stomatitis-pneumoenteritis syndrome, contagious pustular stomatitis, and pneumoenteritis complex.
It is an acute or subacute viral disease of sheep and especially of goats, characterized by sudden fever, nasal discharge, congestion of conjunctiva, bronchopneumonia, necrotic stomatitis and diarrhoea.
The disease is caused by a virus of the Paramyxoviridae family, genus Morbillivirus, antigenically close to the rinderpest virus. Cattle and pigs develop inapparent infections.
To date, PPR has been diagnosed only in captive wild ungulates from families of Gazellinae (dorcas gazelle), Caprinae (Nubian ibex and Laristan sheep) and Hippotraginae (gemsbok).
Experimentally, the American white-tailed deer ( Odocoileus virginianus) is fully susceptible. Cattle and pigs develop inapparent infections. There is a breed-linked predisposition in goats.
Man is not at risk.
Transmission : the disease is transmitted through direct contact between animals ; there is no carrier state.
Occurrence : PPR occurs in Africa, the Arabian Peninsula, the Middle East and India.
There is no specific treatment. Antibiotics may prevent secondary pulmonary infections.
Vaccination : Rinderpest vaccine is commonly used. A homologous PPr vaccine is also available and preferable.
PPR is an OIE List A disease.
