Abstract

Experimental pathogenicity of Mollicutes of bovine udder origin in hamster tracheal ring organ culture.

Abstract

Hamster tracheal-ring organ culture was employed to examine pathogenic effects of 8 isolates of mollicutes of bovine udder origin. The tested mollicutes could be categorized into 2 groups: (1) Mycoplasma F-38, M. mycoides var capri, M. bovigenitalium mixed with M. bovirhinis, and M. bovigenitalium mixed with M. bovirhinis and Mycoplasma F-38 produced significant ciliostatic effect and infiltration of neutrophils and lymphocytes in lamina propria/subepithelium, hyperplasia and desquamation of epithelial lining cells and loss of cilia; and (ii) A. laidlawii, A. axanthum, and unidentified Acholeplasma and a mixed isolate of M. bovis, M. bovigenitalium, Mycoplasma F-39 and A. laidlawii showed insignificant ciliostatic effects and produced mild histopathological lesions. This correlates with the disease causing potentials of the strains.
