Cause: Fowl pox is a common viral disease in pheasants. Slower spreading, characterized by nodular, proliferative skin lesions with no feathers on the surface (skin type), and fibrinoid necrotizing hyperplasia in the upper respiratory tract, oral cavity, and esophageal mucosa (diphtheria type) ), It is also possible that a mixture of skin type and diphtheria type occurs simultaneously. Poultry pox disease can occur throughout the year, but it is most popular in summer and autumn. The infection of fowl pox is often caused by the contact of healthy chickens with diseased chickens. Exfoliated acne is the main way of spreading pathogens. In conditions of crowded, poorly ventilated, dark and humid environments, as well as vitamin deficiencies and poor feeding and management, the condition can be aggravated. Chickling chickens are more susceptible to infection than adult chickens, such as infectious rhinitis, chronic respiratory disease, and can cause large numbers of deaths. Symptoms: It can be divided into three types: skin type, diphtheria type, and mixed type. Skin Type: Mainly in the featherless areas such as the face, ears, and mouth corners, grayish white blisters with large grains of sorghum and large grains of peas begin to appear. Scabs fell off after 2 weeks, forming gray marks. If the scar is peeled off, the skin will expose a bleeding lesion. This type of lesion is generally mild and without systemic symptoms. Severe cases can show apathetic, loss of appetite, weight loss and other systemic symptoms can also cause death. Diphtheria type: also known as mucous membrane type. The main disease is the formation of yellow-white nodules on the oral cavity and throat mucosa, followed by enlargement and fusion of the nodules to form a layer of white pseudomembrane. The diseased pheasant thus displays dyspnea, snoring, and other symptoms. Decline. As the disease progresses, the diseased chicken has swollen eyes, pus, and blindness. Due to difficulties in eating, she quickly lose weight, become apathetic, have systemic symptoms, and have varying degrees of death. China Agricultural Network Editor
