Lymphosarcoma in dogs and cats
There are two kinds of lymphoid granuloma: one occurs in lymphoid organs and tissues, called malignant lymphoma, and there may be tumor cells (lymphocytes) in peripheral blood; the other occurs in bone marrow, called lymphoid leukemia. tumor cells (lymphocytes) are often seen in peripheral blood. The etiology is not clear, feline white blood virus may be the pathogen of some feline lymphosarcoma. Investigations have shown that in cats with leukemia, 1pm 3 develops lymphosarcoma. Nearly 70% of cats with lymphosarcoma tested positive for leukaemia virus.
Main points of diagnosis
Lymphosarcoma can be divided into multicentric lymphosarcoma of dog and cat, lymphosarcoma of digestive tract, lymphosarcoma of thymus, lymphosarcoma of skin and lymphatic leukemia. In addition, cats have lymphosarcoma of the central nervous system and lymphosarcoma of the kidney and eye.
1. The main manifestations of multicentric lymphosarcoma in dogs and cats are depression, emaciation, symmetrical enlargement of all lymph nodes and enlargement of spleen and liver.
2. The main manifestations of gastrointestinal lymphosarcoma in dogs and cats were emaciation, vomiting and diarrhea, and the gastrointestinal wall and mesenteric lymphoid tissue were enlarged.
3. Thymic lymphosarcoma in dogs and cats is usually limited to thymus, most of which are primary and frequently occur in young animals.
4. Lymphosarcoma in the skin of dogs and cats is mainly hard nodules of scattered or densely distributed rice grains to the size of fingers on the skin and under the skin. Nodules depilate, and some form crusts or ulcers. Cutaneous lymphosarcoma often develops into multicentric lymphosarcoma.
5. Lymphoid leukemia mainly shows drowsiness, anorexia, pallor of conjunctiva, large spleen and lymph nodes, sometimes elevated body temperature or symptoms of bacterial infection. Laboratory tests showed that lymphoid tumor cells increased, sometimes up to 100000 / ul. Red blood cells, granulosa cells and thrombocytopenia. The clinical symptoms of lymphosarcoma in other tissues and organs are related to their diseased tissues and organs. Diagnosis requires a biopsy of lymphosarcoma (such as lymph nodes, bone marrow, etc.).
Prevention and cure method
1. When the number of granulosa cells is more than 3000 / ul, bone marrow suppressants can be used, such as cyclophosphamide (see systemic lupus erythematosus). If the number of granulosa cells

How do racoon dogs come into being and how to prevent them?
Rugged raccoon dogs refer to commercial raccoon dogs that cannot be bred in the breeding period after litter weaning, showing that they are not long, small, bony and shaggy, and can only grow to 2.5 kilograms and 3.5 kilograms in the breeding period. Reason: there are many reasons for the formation of raccoon dogs, generally speaking, there are the following: unreasonable nutrition, nutrition is not full price, which is the main reason for the formation of stiff raccoon dogs. Breeders want to save, only feed corn flour or with very little other feed, because the feed is seriously lack of nutrition, can not meet the needs of raccoon dog growth, resulting in raccoon dog is not long, the formation of stiff raccoon dog.

Prevention and treatment of "failure" disease in rabbits
The pathogen of rabbit failure is Pasteurella multocida. When the external environment changes, poor feeding and management, weakening the resistance of rabbits, Pasteurella multocida on the mucous membrane of the respiratory tract take advantage of the opportunity to cause disease, and the tissue of the body bleeds and fails, hence the name "hemorrhagic septicemia" disease, referred to as "hemorrhagic septicemia" disease. (1) symptoms 1. Acute rabbits suddenly fell to the ground and died without any clinical symptoms. But most of the diseased rabbits had mental distress, apnea, dyspnea, elevated body temperature to more than 41 ℃, and nasal outflow.
