Prevention and treatment of necrotic bacilli in deer

Deer necrobacillosis is a chronic infectious disease caused by strict anaerobic necrotic bacilli. It can happen all the year round, which is more popular than in summer and autumn. The source of infection is mainly diseased deer, which can be infected by deer of all ages. Skin injury is the main route of infection, and it can also be infected through digestive tract trauma, saw antler injury, birth canal wound and umbilical cord inflammation. In addition, the ground is wet and muddy, uneven, hot and humid climate, poor management and other easy to promote the occurrence of the disease.

If necrobacillosis occurs in deer, clinical treatment measures should be taken immediately. Local wound therapy thoroughly removes the necrotic tissue and pus and fully exposes the wound, wash around the focus, cut hair, apply iodine tincture, and then rinse the wound with 3% Mustang 5% hydrogen peroxide solution or 0.1% Mustang 0.2% potassium permanganate solution. in order to prevent wound contamination, bandages should be bandaged with gauze bandages impregnated with Vickers plaster, fish tallow or pure tar. In case it falls off. According to the condition, it is usually treated once every 2-3 days until the wound is healed. The purpose of systemic therapy is to control infection and prevent the deterioration of the disease from spreading to the viscera and the whole body. Most of them were treated with antibiotics. Drug sensitivity test showed that Bacillus necroticus was extremely sensitive to oxytetracycline, tetracycline and cephalomycin, and was also highly sensitive to penicillin, polymyxin and kanamycin. The above antibiotics can be selected in each deer farm according to the situation. General penicillin, polymyxin, etc. according to adult deer 2 million units-2.5 million units dosage, intramuscular injection, young deer appropriate reduction. Oxytetracycline and oxytetracycline can be taken internally at a dose of 0.05 grams per kilogram of body weight. If systemic therapy and local wound therapy are carried out at the same time, good results can be achieved.
