Résumé : |
Samples of hides from several established cases of bovine dermatophilosis were processed for fine structural evaluation of associated pathologies, employing standard transmission electron microscopical analytical procedures. The hides of 2 of the cases were chrome-tanned into shoe upper leathers and physically examined for gross defects attribuable to the disease process. Classical changes observed within the infected hides were hyperkeratosis, edematous epidermal strata denoted by widening of intercellular spaces with loss of cellular contracts, total degeneration and necrosis of epidermal cells, detachment of basal epidermal cells from underlining basal laminae, breakages in contiuities of basal laminae, collagen fibrillar destruction with spatial disorientation in the grain, and dislodgement of collagen bundles by excessive cellular infiltrates within the corium. The most commonly associated pathogen - Dermatophilus congolensis was located within the keratinized epidermal layers, and appeared to have contributed immensely towards evoking the inflammatory reactions. Gross changes of leather from infected hides were manifested as blemishes in the form of pittings and wrinklings on the grain enamels. These changes were described to fine structural pathologies of the grain and corium which bodered on structural framework of collagen fibrils, fibers and bundles. |
