Camel contagious ecthyma (CCE) is a viral disease of camelids that is caused by a Parapoxvirus (PPV) which is a DNA virus of the viral family: Poxviridae. Diseases affecting camels in Nigeria are scarcely reported. CCE or the laboratory detection of camel PPV (CPPV) has not been reported in Nigeria. This study investigated and described the clinical presentation of CCE and molecular detection of CPPV in Nigeria. Suspected cases of CCE were reported in a farm, live animal market and abattoir, in three different states (Bauchi, Plateau and Zamfara) in Northern Nigeria. Skin scabs, lungs, liver and intestine samples were collected. Polymerase chain reaction (PCR) was carried out using the primers which targets the RPO30 gene fragment of the genus PPV. The clinical signs observed from the suspected cases of CCE were proliferative skin lesions, papules, scabs on the lips and nares. CPPV was detected in 80.0% (4/5) of the samples collected by PCR. CCE was diagnosed based on clinical signs and PCR results. This is the first report of CCE in Nigeria. Further studies should be carried out to genetically characterize the CPPV circulating in Nigeria.
