Cl. Coccidea typical life cycle stages |
merogony/schizogony-> asexual reproduction of merozoites to increase number gamogony- merozoites become gametes -> micro/macro sporogony--> when the zygotes are expelled into the env they undergo sprogony to become sporozoites which is the infective stage |
|
|
F. Eimeidae |
ph. apicomplexa o. euccocidea direct LC oocyst configuration: 1:4:2 |
|
|
emeria tenalla |
found in the intestines of chickens look at the vili for the parasites can see young stages severe path' destroys intestinal tissues has 1:4:2 configuration |
|
|
emeria stiedae |
in bile ducts and liver of rabits can see later stages of parasites can cause liver failure |
|
|
F. Sarcocystidae |
ph. apicomplexa c. coccidiea indirect life cycle configuration: 1:2:4 IH: tachyzoites (fast reprod merozoites invade host tissue ) and bradyzoites (large merozoites in zoitocsysts, trophically transmitted to DH) |
|
|
taxoplasma gondii showing microgemetes in a microgamont |
F. sarcocystidae cl. coccidae ph.Apicomplexa dh: cats IH: many, including humans DH infected by sporulated oocysts or bradyzoites |
|
sarcocystis sp this shows the large irregular zoitocyst with bradyz |
ph. apicomplexa cl. coccidia f. sarcocystidae dh: carnivores ih: herbivores DH only infected by bradyzoites large irregular zoitocysts visible in IH muscle |
|
|
Toxoplasma gondii
tachyzoites |
ph. apicomplexa cl. coccidea f. sarcocystidae tachyzoites are fast reproducing and kill alot of host tissue this stage spreads and if in a pregnant woman can cross the placenta and harm the fetus |
|
|
toxoplasma gondii bradyzoites in a zoitocyst |
bradyzoites are larger than tachyzoiteas because they encyst, also slower reproduction both are found in the IH |
|
|
haemgregarines |
o.euccocidea infect repltiles like frogs: RBC has a nucleus unlike humans, can tell if infected if the nucleus is pushed to the edge of RBC and there is a banana shapped thing inside |
|
|
toxoplasma gondii |
ph. apicomplexa cl. coccidea f. sarcocystidae trophozoite containing merozoite |
|
|
eimeria tenella |
ph. apicomplexa cl. coccidea f. eimeridae can see advanced zchizogony-- production of many merozoites it looks like an empty sac but its not lol |
|
|
e. tenella macrogamonts |
