what are Trophozoite
mobile, feeding stage
Trophozoites are the active, reproducing and usually motile form of a protozoan parasite or bacterium that lives inside the host’s body. This term is used to describe the stage of protozoan parasites such as Plasmodium falciparum, the causative agent of malaria, or Entamoeba histolytica, which causes amoebic dysentery.
During this stage, the trophozoites feed on host cells or tissues and multiply by dividing into two daughter cells, resulting in the increased parasite load in the host’s body. Trophozoites possess various mechanisms for attachment, feeding, and evasion of the host’s immune system, which enable their survival and spread within the host.
Identification and quantification of trophozoites can be done through microscopic examination of the host’s blood, stool, or tissue samples, using specific stains or molecular techniques. Accurate diagnosis and timely treatment of trophozoite infections are crucial to prevent the severe and sometimes fatal consequences of these parasitic diseases.
