A severe exudative-crustous and proliferous dermatitis in a 2 year old sheep caused by Dermatophilus congolensis (observed for the first time in Italy), is reported. The disease was reproduced experimentally in sheep, goats, rabbits and guinea pigs, whose skin was treated in different ways before infection. E.L.I.S.A. and Immunoblotting tests carried out in experimentally infected sheep, showed the antigenic complexity of the pathogen and the existence of cross-immunity to the protein components.

Abstract
A severe exudative-crustous and proliferous dermatitis in a 2 year old sheep caused by Dermatophilus congolensis (observed for the first time in Italy), is reported. The disease was reproduced experimentally in sheep, goats, rabbits and guinea pigs, whose skin was treated in different ways before infection. E.L.I.S.A. and Immunoblotting tests carried out in experimentally infected sheep, showed the antigenic complexity of the pathogen and the existence of cross-immunity to the protein components. Intradermoreaction tests were carried out in all animals. The development of a positive reaction only in rabbits and guinea pigs, confirmed that these animals have a cellular immunity against Dermatophilus congolensis.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
