| On the other hand, the sporozoites may lie in the salivary gland alive and virulent for several weeks. |
| The sexual phase of the Plasmodium life cycle is completed with the fertilization of a macrogamete by a flagellar microgamete, and the subsequent generation of sporozoites. |
| Oocytes ingested from contaminated soil or other sources excyst in the duodenum, and released sporozoites invade the intestine. |
| The sporozoites migrate to the salivary glands and are inoculated into a new vertebrate host when the mosquito feeds. |
| Infection by sporozoites reduces the fecundity of mosquitoes. |
