Swine pox in Nigeria.

An outbreak of swine pox on a pig farm in Ibadan, Nigeria is reported. Diagnosis was based on clinical and pathological signs and the observation of poxvirus particles in a serum sample. Neonatal deaths were common in the outbreak. Indigenous pigs did not show any sign of the disease even though mixed breeds were kept in the same pens. It is suggested that indigenous pigs were probably carriers of the swine pox virus.
