Clinical diagnosis: The onset of fur animals is mainly characterized by diarrhea, and the animal body is emaciated and inverted by hair. The main symptom of autopsy is hepatomegaly and bleeding, and in severe cases, the liver has necrotic foci. The cecum has bleeding spots and ulcerative necrosis foci, and the cecum is filled with pus-like feces.
Laboratory diagnosis: microscopic observation of trichomoniasis as a polymorphic insect body, varying in size, approximately round or amoeba-like, pseudopod blunt round. The encapsulated stage has a trophoblast. It is common to have 1 flagellar, which is in a pendulum-like movement and has a vesicle-like nucleus. Collect the contents of the cecum and place them on a glass slide, dilute the posterior microscopy with normal saline, and the moving insect body can be seen, in the form of a circle and pear, as a pendulum movement.
Treatment: Immediately stop feeding feed containing poultry by-products such as chicken intestines and chicken liver, and add fresh marine fish, eggs, etc. Metronidazole is given as directed for drug use.
Prevention: Contamination of drinking water and feed may be the main route of transmission. Keeping feed feed hygienic in feedlots and water in drinking rooms is key to preventing the disease. Poultry products must be cooked and fed to keep the feed clean and hygienic. In addition, reducing the feeding density, maintaining good ventilation, killing flies, daily cleaning and disinfection of eating utensils and regular disinfection of the environment can effectively prevent the disease.
