Comparative study of pathogenicity of experimentally produced Borrelia anserina infection in commercial broiler and Desi chicks.
48 Desi chicks and 48 broilers were divided into 4 equal groups and 3 groups were infected with B. anserina orally, subcutaneously or intramuscularly. Three chicks from each group were killed after 48, 72 and 120 h. Broiler chicks developed disease after infection by all 3 routes while Desi chicks infected orally did not develop disease. Symptoms and PM changes were less severe in Desi chicks than in broiler chicks. It is concluded that Desi chicks are more resistant to the disease than are broilers.
