Electron microscopic view of a morbillivirus

Peste des petits ruminants (PPR; 'goat plague') is a notifiable viral disease of cattle[1].

This disease is caused by a morbillivirus (f. Paramyxoviridae).

Cattle are usually infected asymptomatically and are exposed to PPR infection naturally[2]. The transmission mode to other ruminants may be direct or indirect, and cattle may play a role as subclinical hosts for the virus[3].

Diagnosis is most accurately determined based on presenting clinical signs supported with evidence of viral presence using ELISA[4] or PCR assay analysis of infected samples.

The disease must be distinguished from other causes of stomatitis including bovine mucosal disease, malignant catarrhal fever, rinderpest, foot and mouth disease, contagious ecthyma, blue tongue, epizootic haemorrhagic disease, papular stomatitis and vesicular stomatitis[5].

It should be noted that cattle which have been exposed to the PPR virus show poor responses to live attenuated Rinderpest vaccine[6].
