title: Fowlpox virus in the Sudan.
abstract: A virulent fowlpox virus was isolated from a natural outbreak of the disease in the Sudan. The virus was used for experimental transmission of the disease to susceptible chickens. Scarification and intravenous methods were used to infect one-month-old chickens. Scarification induced typical pox lesions at 5-7 days postinoculation, whereas intravenous injection induced only swelling of combs or wattles, at 10-11 days postinoculation, although neutralizing antibodies against fowlpox virus were detected 2, 3, and 4 weeks postinoculation. The histopathological features of the pox lesions obtained in both natural and experimental infection were described.
