| 41. | Trophozoites : The cytoplasm is compact, staining a deep blue while the nucleus stains deep red.
|
| 42. | The trophozoites are usually found in mature erythrocytes but may be seen in polychromatic erythrocytes during heavy infections.
|
| 43. | There they enter hepatic cells, transform into the trophozoite form and feed on hepatic cells, and reproduce asexually.
|
| 44. | In some species, the sporozoites and trophozoites are capable of asexual replication a process called schizogony or merogony.
|
| 45. | In all species, two mature trophozoites eventually pair up in a process known as syzygy and develop into gamonts.
|
| 46. | The cyst form also differs from the trophozoite form because it is non-motile and does not undergo reproduction.
|
| 47. | The parasite nucleus is small, usually terminal in position or with chromatin concentrated along the outer periphery of trophozoites.
|
| 48. | After gorging itself on its host, the trophozoite undergoes schizogony and develops into a schizont, later releasing merozoites.
|
| 49. | The trophozoite ( feeding-dividing form ) is approximately 10-20 ?m in diameter and feeds primarily on bacteria.
|
| 50. | Distinguishing features of the trophozoites are large karyosomes and lack of peripheral chromatin, giving the two nuclei a halo appearance.
