Abstract
of Hokkaido. It was once characterized by hyperemia of the conjunctivae and lacrimation, but, in these 2years, by keratitis with white-turbid conjunctivae. It frequently attacked relatively young cattle.
Etiologically, Moraxella boviswas isolated from 17 of 65 animals with the remarkably whiteturbid cornea, andMor. nonliquefaciensat high frequency from animals presumed to be in the early stage of disease and healthy cattle.Branhamella catarrhalis and Gram-positive cocci were also isolated from animals involved in chronic infection with vascularization in the white-turbid cornea.Mycoplasma spp. were found in most animals manifesting various symptoms and some apparently healthy ones, andUreaplasma spp. in one infected and 8 healthy animals.
