Clinical assessment of postinfection, postcontact and postvaccination immunity manifestation after experimental inoculation of calves with Trichophyton verrucosum culture.

摘要: Immunity against ringworm has been well examined, but the knowledge of its development after repeated infection is limited. Therefore, immunity developed a single or double contact with various doses Trichophyton verrucosum strain was investigated in calves which had not shown any signs dermatophyte. In total six individual experiments were performed on 117 calves. Experimental virulent T. used to investigate animals' immunity. Calves showing severe trichophytosis application high culture immune reinfection by equally this A similar protection level reached intramuscular revaccination recovery from moderate course induced two inoculations low doses. If illness same dose, lower. Animals displaying no inoculation insufficient There animals having previous subinfectious through undamaged skin. The results obtained suggest that postinfection depends disease extent and frequency administration infectious agent. postcontact cannot be excluded
