| On the other hand, the sporozoites may lie in the salivary gland alive and virulent for several weeks. |
| The sporoplasm may be either a plasmodial mass, with numerous nuclei, or may form a certain number of uninuclear sporozoites. |
| The sporozoites migrate to the salivary glands and are inoculated into a new vertebrate host when the mosquito feeds. |
| They then watched as sporozoites traversed Kupffer cells using a special process distinct from ordinary parasite locomotion. |
| Tissue damage to the host's liver, kidney, spleen, lungs, or other organs can occur when the vector injects sporozoites that enter host cells to develop into meronts. |
| Inside the liver, the sporozoites change form and then grow and divide into thousands of merozoites. |
