| 41. | After several days the oocyst produces ~ 100 sporozoites that leave and migrate to the salivary glands of the fly.
|
| 42. | Once through the epithelium, the ookinete enters the basil lamina, and forms an oocyst where meiosis takes place.
|
| 43. | The oocyst is about egg-shaped and has a smooth, single-layered wall about 1 ?m thick.
|
| 44. | Another problem is that even under a microscope, it is not possible to reliably tell when the oocyst is dead.
|
| 45. | Upon traversing the midgut wall, the ookinete embeds into the gut's exterior membrane and develops into an oocyst.
|
| 46. | Over the period of a 1 3 weeks, the oocyst grows to a size of tens to hundreds of micrometres.
|
| 47. | Within the oocyst the nuclei migrate to the surface of the oocyst and gather cytoplasm around them becoming known as sporoblasts.
|
| 48. | Within the oocyst the nuclei migrate to the surface of the oocyst and gather cytoplasm around them becoming known as sporoblasts.
|
| 49. | It has an oocyst residuum and Stieda bodies, structures that are absent in some other " Eimeria ".
|
| 50. | Although cats can also be infected by ingesting oocysts, they are much less sensitive to oocyst infection than are intermediate hosts.
