Toxoplasma canis and Ancylostoma canis

Parasites of dogs, it is reported that the infection rate of Toxocara canis in puppies in Chengdu, Sichuan is as high as 82.5%, and 3.19% of pet dogs in Shanghai, Guizhou Province The infection rate of Ancylostoma in dogs is as high as 93.33%. After these parasites invade the human body through the mouth, its normal development is hindered. However, its larvae migrate everywhere in the human body's internal organs, subcutaneous or muscles, causing local tissue damage, causing fever, creeping rash, pulmonary symptoms and increased eosinophils.

Babesiosis

is transmitted through the bite of a tick parasitic on dogs. After the tick enters the human body, it can generally cause discomfort, fatigue, chills, fever, headache, myalgia, etc. Different degrees of hemolytic anemia, jaundice or hemoglobinuria, liver and spleen may be enlarged. In severe cases, the onset of symptoms is sudden, with symptoms such as chills and sweating, the body temperature can be as high as 40°C, liver and kidney failure, coma, and even death. Patients often delay the course of the disease due to undiagnosed diagnosis, causing intermittent attacks of symptoms.

Hydatid disease

Hydatid disease is a parasitic disease caused by Echinococcus tapeworm parasitizing humans and some animals. my country is mainly distributed in pastoral areas in northwest China. Echinococcus canis in Xinjiang The infection rate reached 7%-71%. Echinococcus tapeworms lay eggs in the small intestine of dogs. The eggs are excreted with dog feces and contaminate water sources, food, utensils or hands, and then enter the human body through the mouth. The common parasitic sites are liver (65.37%), lungs (23.18%), and abdominal cavity. (2.36%), brain (2.07%), mixed organs (3.2%). The larvae incubate and parasitize in the above-mentioned organs and tissues, forming cysts. Cysts grow slowly, and it often takes several years or ten years for symptoms to appear. The main damage is that the cyst takes up space and compresses surrounding tissues or organs. However, if the cyst ruptures, the cyst fluid will cause a sharp anaphylactic shock. Even cardiac arrest.

Canine heartrofilariasis

This disease is found wherever dogs exist, so the disease is widely distributed, and the natural infection rate of dogs is 10-30%. The insect is mainly transmitted to humans through mosquito bites. It migrates in the subcutaneous soft tissue or blood vessels and lymphatic vessels of humans, and may cause severe tissue reactions or suppuration. In addition, it can parasitize the human right ventricle and pulmonary artery, causing cough, chest pain, hemoptysis, chest tightness, myalgia or fever, etc. It can easily be misdiagnosed as tuberculosis, pneumonia or lung tumors.​
