The Haemogregarines are the most common parasite of reptiles. They are found anywhere reptiles and amphibians live and in a large part of the populations. Yes, even here in Vermont! There is no evidence that this parasite is a hram to its host and it is very rare in mammels.

PathologyEdit

This parasite is found in the liver's red blood cells of its hosts during its gametocyte stage. It is obvious because while looking at the red blood cell you will notice that the the central nucleus of the cell is elongated and pushed to one side. This is because the parasite is taking up a large part of the red blood cell. 

This parasite is vectored by leeches, flies, and other biting insects. In the vector it is in its sporogony stage. 

Life CycleEdit

Spores are transmitted to the host via a bite from a vector. Sporozoites turn into trophozoites and begin thier feeding stage. They undergo Merogony where the trophozoites replicate asexually and fom schizonts and then merozoites which again form trophozoites. This cycle can go on but some trophozoites branch off and form gamonts in the liver of the host. These undergo gamogony which is sexual replication. Male and female gametes replicate and the female gametes become fertilized forming zygotes. Zygotes  can then be released into the environment and taken up by a vector. In the vector they undergo sporogony which is asexual reproduction that forms spores to be, once again transmitted to a host.
