Abstract:

Twenty goats in two groups of 10 were injected intradermally, with Corynebacterium pseudotuberculosis. The doses of infection were 1x105 and 5x104 colony forming units for groups 1 and 2 respectively. Thereafter, a goat from each group was killed every 2-3 days and examined for gross and microscopic caseous lesions in the draining lymph nodes. Bands or zones of macrophages and polymorphonuclear granulocytes were observed on the second day of infection in both groups. Gross caseous lesions were observed from day 8 and 9 of infection respectively. Positive bacterial agglutination test and haemolysin inhibition test titres were detected after 15-17days and 20 -25 days of infection respectively. These results indicated that caseous lymphadenitis is a subacute disease with an incubation period of 8-9 days but it is not detectable serologically until after 15 days of infection.
