Demodex is translucent and milky white, with a worm-like body narrow and long body length of 0.25~0.3mm long and 0.04mm wide. The worm body can be divided into three parts: front, middle and rear. The mouthparts of the insect are located in the front of the insect body and are horseshoe-shaped. There are also four pairs of very short feet in the middle, with 5 sections of the feet; the rear of the insect body is relatively slender, with densely spreading lines on the surface of the rear. The entire life history of
dog demodex mite is carried out in hair follicles, from eggs, larvae, nymphs, and adults, and its nymphs have 3 stages. Demodex mites in dogs mainly parasitize the upper part of the hair follicles of the onset skin, and can be transferred to the bottom soon, and rarely parasitize in the sebaceous glands. In addition to being able to parasitize in hair follicles, the pathogen can also parasitize in the tissues of dogs and lymphatic tissues, in which some of them will reproduce.
Prevention and treatment methods:
Treatment of mites and bacteria at the same time, combining injection drugs with external drugs. To treat mite-shaped infections, you can inject doramectin, ivermectin, avermectin and other drugs subcutaneously, once every 7 days, each course of treatment for 4 to 5 weeks. Systemic itching can be injected with dexamethasone or prednisone acetate, primine, etc., but the use time should not exceed 3 days to avoid the growth of bacteria; when pustules or abscesses appear, antibiotics should be given in combination with treatment. Applying the skin of a dog without suffering from ivermectin is an effective auxiliary therapy.
