Sažetak

Typical orf lesions were successfully produced (experimently) on the udder dermis of lactating sheep and goats. The animals were subjected to daily clinical examination and the developing lesions were monitored and recorded. The lesions involved were erythema, papules, pustules and firm irregular scabs on the skin of the udders. One goat developed unilateral moderate udder fibrosis and two of the sheep developed bilateral similar lesions. Examination of milk samples from infected animals by California Mastitis Test (CMT) and Mastitis Yellow Card Test was found positive for mastitis. Staphylococcus aureus, Staphylococcus epidermidis, Proteus mirabilis and Arcanobacterium pyogenes were recovered from the milk of affected animals. All the infected animals were sero-converted to orf infection and produced neutralizing antibodies. The causative orf virus was re-isolated from the scabs of their lesions. The bionomics of the disease was discussed.
