Abstract

Teat lesions, produced in ewes by an experimental chapping procedure, were found to facilitate experimental infection with Mannheimia haemolytica, as assessed by observations on infection of the teat skin, teat duct and mammary gland, and on the production of mastitis. The origin of the M. haemolytica strain used (ovine tonsillar or mammary infection) did not appear to influence the results. In a second experiment, in which ewes continued to suckle their lambs but were not deliberately infected, chapping was shown to favour infection by Staphylococcus epidermidis, Staphylococcus aureus and M. haemolytica.

摘要

通过实验性皲裂程序在母羊身上产生的乳头损伤，经对乳头皮肤、乳管和乳腺的感染情况以及乳腺炎的发生情况进行观察评估，发现其会促进溶血曼氏杆菌的实验性感染。所用溶血曼氏杆菌菌株的来源（羊扁桃体感染或乳腺感染）似乎不影响结果。在第二项实验中，母羊继续哺乳羔羊但未被故意感染，结果显示皲裂有利于表皮葡萄球菌、金黄色葡萄球菌和溶血曼氏杆菌的感染。
