| life cycle of Plasmodium spp. |
|
Definition
| The life cycle of Plasmodium spp. starts with the mosquito ingesting gametocytes from an infected human, there is exflagellation of microgametocytes and fertilization of macrogametocyte, formation of oocysts and formation of sporozoites then migration of sporozoites to salivary glands. The mosquito takes a blood meal and injects the infective sporozoites, the exoerythrcytic phase in which schizogony produce thousands of Merozoites, and then the Erythrocytic phase in which there is a production of gametocytes. |
