This form of arthritis usually appears in an insidious form after abortion, retention of the foetus, or post-partum metritis. In cases of epizootic abortion infectious rheumatism sometimes assumes an epizootic form, and completes the devastation begun by abortion. Under other and much rarer circumstances it may follow enteritis of adults or attacks of mammitis, etc. The pathogeny of these forms of arthritis is not. Fig. 53.—Infectious rheumatism. Arthritis of the left stifle joint. difficult to understand, for in the greater number of instances they form delayed consequences of local uterine infection. The soluble products secreted by infectious organisms multiplying within the uterus are absorbed by the uterine mucous membrane, causing slow intoxication ; and in consequence of the special elective aflfinity which the toxins show for the articular serous membranes, and in many cases also for the visceral serous membranes, the special characteristics are developed. Under certain circumstances the joint cavity may even become the seat of true microbic infection. Symptoms. The appearance of the first symptoms is difficult to identify, for many cows abort, fail to " cleanse," or become affected with metritis without infectious rheumatism supervening. It is a long-delayed condition, which may be postponed for weeks or even for several months after an abnormal parturition, and to a time when the symptoms of metritis have almost entirely disappeared. The onset is characterised. Please note that these images are extracted from scanned page images that may have been digitally enhanced for readabil
