| The cyst wall disintegrates in the small intestine, releasing motile trophozoites. |
|
| Exposure to bile is the primary stimulus for encystation, where trophozoites transform into cysts that pass out with the feces. |
|
| Ingested cysts hatch into trophozoites in the small intestine and continue moving down the digestive tract to the colon. |
|
| Merozoites invade erythrocytes, differentiate into trophozoites, and divide to become blood schizonts. |
|
| Biopsy of colonic ulcer edges may yield intramural trophozoites but carries with it the risk of perforation. |
|
| These were determined to be the trophozoites of a gregarine parasite of the insect, and the present paper records the observations which have been made on this species. |
|
| Recognition of amebic trophozoites and cysts was very poor on the CAP NGC challenges. |
|
| The trophozoites were the most abundant cells, with an intracellular and also extracellular location and an elongated shape. |
|
| The toxoplasmic trophozoites causing acute toxoplasmosis are referred to as Tachyzoites, and are typically found in bodily fluids. |
|
| These similarities included ring forms and mature trophozoites with stippling of erythrocytes. |
|
| Results of quantitative buffy coat analysis were positive for malaria trophozoites, schizonts, and gametocytes. |
|
| Fresh preparations were examined visually at magnifications of 100X and 400X over approximately 100 fields for parasite cysts, trophozoites and helminthes eggs. |
|
| Synchronized cultures of P. falciparum trophozoites were grown in human RBCs and incubated with increasing concentrations of purified human platelets. |
|
| After this outbreak, laboratory investigations found that propylene glycol may cause Acanthamoeba trophozoites to encyst, thereby making them resistant to disinfection. |
|
| Trophozoites showed very active movement, with wide pseudopods of rapid formation. |
