Prevention and treatment of chlamydia trachomatis in pigeon

Chlamydia is commonly known as bird plague. Chlamydia psittaci is an infectious disease caused by pathogenic microorganisms. Many birds can be infected. If one pigeon is infected in the flock, it quickly spreads to the whole flock, with a higher incidence but less death. Transmission via feed and drinking water contaminated with sick pigeon faeces or contact, from the digestive or respiratory tract and skin wounds. Young pigeons of 2~3 weeks old were more affected. Adult pigeons were inconspicuously infected. It occurs mostly in summer and autumn.

Symptoms: sick pigeon spirit wilted, feathers loose chaos, loss of appetite, diarrhea, discharge gray or light green watery loose feces, feathers near the anus are often contaminated by feces, pigeon body emaciation. There is unilateral or bilateral conjunctiva inflammation, outflow of serous secretions; nasal disease early outflow of watery secretions, later into yellow viscous secretions; breathing issued a "cluck" sound. Chest muscle atrophy can not take off, a few sick pigeons appear nervous symptoms. Acute people often die suddenly. Adult pigeon symptoms are generally mild and self-healing. Autopsy showed obvious enlargement of liver and spleen, pale yellow necrotic foci of different sizes on the surface of liver tissue, cardiac hypertrophy, pericardial thickening, congestion and hemorrhage. Thoracic cavity and visceral adventitia are covered with cellulosic inflammation, and their surfaces are often covered with cellulosic exudates.

Diagnosis: According to its epidemic characteristics, clinical symptoms and pathological changes of autopsy, preliminary diagnosis can be made, and diagnosis must be made by pathogen isolation and identification.

Prevention and treatment methods: To prevent this disease, we should strengthen feeding management, maintain sanitation in the house, clean and dry, and avoid stress stimulation. Pigeon furniture should be kept clean and thoroughly disinfected regularly with caustic soda or milk of lime. Pigeon found suffering from this disease should be blocked in time, isolation treatment, dead pigeons buried deep to prevent the expansion of infection. Since this disease is a zoonotic disease, breeders should also pay attention to protection to avoid infection. Antibiotics, such as oxytetracycline, tetracycline, chlortetracycline with 100 thousand units or erythromycin, etc., according to 0.04%~0.06% of the dosage mixed into feed feeding, each 50 ~ 60 thousand units, twice a day, for 5 days as a course of treatment, intermediate drug withdrawal for 2 days, for two courses of treatment. It is difficult for children pigeons and serious cases to feed medicine, intramuscular injection is feasible, continuous injection for 1~2 weeks, can alleviate clinical symptoms and gradually recover.
