The incubation period was also observed in both groups of animals. In natural infection, the incubation period was 13 days, whereas, in artificial infection this period was seen to be 25 days. The site of onset of lesion, in natural infection group, was over the nose, whereas in experimentally infected cases the lesion started from the base of the ears, after which the spread of lesion was more or less similar in both groups. During first two weeks pei. the lesion was restricted on the facial region of the body. From third week onward, the lesions were seen on other parts of the body e.g. paws of hind and fore legs and external genitalia of both male and female. There were scab formation, alopecia and wrinkling of skin with dull, depressed and emaciated condition of the animals. On examination of the skin scraping, intensity of infection was found to be maximum at seventh and eighth week P.i. in artificially infected group (++++) and eighth week p.i. in naturally infected group (****).EnglishThesis
