title: Comparative pathogenicity of Theileria annulata strains.
abstract: Twenty three susceptible crossbred calves were inoculated with five Indian strains of Theileria annulata, collected from natural cases of tropical theileriosis at Ludhiana, Hissar, Jaipur, Uruli-Kanchan and Bangalore. All the strains produced clinical disease with typical symptoms and lesions of acute theileriosis. The strains were considered highly virulent and equally pathogenic.
