تشخيص التهاب المفاصل في العجول الناتج عن الإصابة بجراثيم Mycoplasma bovis باستخدام اختبار الإليزا غير المباشر

Abstract EN

The aim of this study to investigated of antibodies of Mycoplasma bovis bacteria in affected calves with arthritis by using indirect ELISA test .

the study was conducted examination of 2356 head of calves , both sex and different ages , included 52 herds , in Mosul city , Mosul .

Iraq .

The results was revealed that Indirect ELISA test have highly sensitivity for detection of monoclonal antibodies of M.

bovis bacteria , in all diseased cases in present study .

also , The study revealed that the total percentage of antibodies in blood serum of affected calves was 76.09% , and the mean of antibody titers of this bacteria in examined calves was 23.77±2.26 in mild cases , 51.11±1.32 in moderate cases and 81.80±3.10 in sever cases ,and there was significantly increased in the titers of affected groups when compared with serum of animals control group.

There was significantly increased body temperature , pulse and respiratory rates at the level (P<0.05) in affected groups when compared with control group .

The mean clinical signs in affected calves with arthritis was pain , swelling of the affected joint , exudation , lameness and loss of the body weight .
