Will there be parasites in the blood?

The specific common ones are as follows

1. Plasmodium: Plasmodium is a malaria pathogen spread by mosquitoes. There are three common plasmodium species: vivax malaria, vivax malaria and falciparum malaria. Examination of plasmodium in peripheral blood smear is a reliable method to diagnose malaria, and finding that plasmodium is positive can be used as a reliable basis for diagnosis. Negative results can't deny the diagnosis, so it needs to be rechecked many times or checked by genetic diagnosis.

2. microfilaria: microfilaria is the protozoa of filariasis. There are two kinds of common filariasis infections in China, Bancroftian filariasis and Malayan filariasis, both of which are transmitted by mosquitoes. Peripheral blood smear is the main diagnostic method, positive results are the basis of diagnosis, and negative results need to be reviewed many times.

3. borrelia recurrentis: borrelia recurrentis is the pathogen of relapsing fever, which is spread by human lice. Positive results are the basis of diagnosis, and negative results need to be reviewed many times.

4. Toxoplasma gondii: Toxoplasma gondii is the pathogen, cats are the main source of infection, and people are generally negative. Positive results are the basis of diagnosis, and negative results need to be rechecked many times, or checked by immunological methods and genetic diagnosis methods.

5. littoral corpuscle: littoral corpuscle is the pathogen of kala-azar and a kind of flagellate. Liver and spleen puncture fluid can often be used for examination, or bone marrow and lymph node puncture fluid can be used for examination. Positive results can be diagnosed, and negative results need to be reviewed.
