Abstract


An acute outbreak of glanders occurred in thirteen horses in a stable farm at Diyala province, Iraq. Three horses were died and the rest ten showed different clinical signs of glanders including fever, anorexia, emaciation, mucopurulent, nasal discharge and one to two ulcerative nodules located in the nasal mucosa, submaxillary lymph node enlargement and swelling and enlargement of both testes. Both horses showed multiple ulcerative nodules on the hind limbs and abdomen. From these ulcerative nodules of the skin and nasal cavity, Burkholderia (Pseudomonas) mallei were isolated. Both horses give positive mallein test and variable levels of antibodies titers arranged between 80 – 640 with a mean of (224 ± 66.58). Three horses were died and showed extensive acute bronchopneumonia composed of purulent exudates in the bronchi, bronchioles and in alveoli. In other sections purulent exudates admixed with edema and fibrin filled the alveolar lumina. No granulomatous reactions were seen in the pulmonary tissue examined except that, in certain sections focal necrotizing pulmonary tissue with purulent exudates may be become pyogranuloma in chronic stage of the disease. Upper respiratory tract lesions include mucopurulent tracheitis rhinitis together with ulcerative nodules located in the nasal mucosa. Also enlargement of the bronchial and submixallary lymph nodes. Cutaneous lesions consisted of ulcerative nodules filled with pus distributed on the hind limbs and abdomen with suppurative lymphangitis giving farcy pipes form of cutaneous glanders lesions.
