A blood parasite is a parasite that is parasitic in the blood or blood cells of an animal.

Right!

A blood parasite is a parasite that is parasitic in the blood or blood cells of an animal.

Parasites that are parasitic in the blood or blood cells of an animal. In general, it may cause increased blood viscosity, cause thrombosis, insufficient blood supply to the brain, anemia and malnutrition, which is extremely harmful to health.

All parasites that are parasitized in the blood and blood cells can be found in the blood. These protozoa and filamentous parasites are parasitized in human blood and red blood cells and need to be confirmed by blood tests or bone marrow tests. Commonly used methods are blood smear method (thin blood film and thick blood film method) and bone marrow puncture method.

Common blood parasite tests are:

1. Plasmodium inspection: Plasmodium is a malaria pathogen that is transmitted by mosquitoes. There are three common types of Plasmodium vivax, P. malariae, and P. falciparum. Peripheral blood smear test for Plasmodium is a reliable method for diagnosing malaria. If a positive Plasmodium is found, it can be used as a reliable basis for diagnosis. Negative results cannot be diagnosed and require multiple rechecks or genetic testing.

2. Microfilariae inspection: Microfilariae are the protozoa of filamentous worms. Common types of filamentous worm infections in China include two types of filamentous worms, Bancaria filariasis and Malaria filaria, which are transmitted by mosquitoes. Peripheral blood smear is the main method of diagnosis. Positive results are the basis for diagnosis. Negative results need to be reviewed multiple times.

3 Retrieval of Treponema pallidum: Retrieval of Treponema pallidum is a pathogen of relapsing fever, transmitted by human lice. Positive results are the basis for diagnosis. Negative results need to be reviewed multiple times.

4 Toxoplasma examination: Toxoplasma is the pathogen of Toxoplasmosis. Cats and felines are the main source of infection. Humans are generally negative. Positive results are the basis of diagnosis. Negative results need to be re-examined multiple times, or checked with immunological methods and genetic diagnostic methods.

5. Lithosome examination: Lithosome is the pathogen of black fever, which is a kind of flagellate. It can often be checked by puncture fluid of liver and spleen, but also by puncture fluid of bone marrow and lymph nodes. Positive results can be confirmed, and negative results need to be reviewed. ^[1]
