Third, laboratory diagnosis of subcutaneous edema fluid from the affected part, staining microscopic examination, can be seen in pairs of Gram-positive cocci. In bacterial culture, the colony was moist, smooth, round and protruding yellow colony. It was diagnosed as staphylococcosis in chickens. Fourth, prevention and control measures for isolated breeding of diseased chickens; timely cutting off beaks to prevent chickens from pecking each other, adding 1% of Yuanling (No. 2) to feed to treat pecking, keeping the environment of chickens clean and hygienic, disinfecting them alternately with Baidu killing and spraying Lingdan 1R600 concentration on a regular basis to remove pathogens. Diseased chickens were injected intramuscularly with gentamicin at 5000 units per 7.5kg body weight twice a day for 4-5 days. 0.1% chloramphenicol powder was added to the feed for 5 days. Satisfactory results can be obtained by improving environmental conditions, strengthening feeding management and treating with sensitive antimicrobials.
