Transcript of Parasites causing anemia

Parasites causing anemia Microcytic anemia is a type of iron deficiency, and the term "microcytic" means "small cells" and refers to the appearance of iron-deficient red blood cells. These cells cannot deliver oxygen to target tissues as efficiently as normal cells Hemolytic anemia occurs when red blood cells are destroyed or removed from the circulation prematurely. so red cell lifespan is shortened, and thus the rate of turnover of red cells is higher Habitat: Small intestine
Definitive host: Human
Route of infection: Filariform larvae penetrate the skin of human
Infective stage: Third stage larvae (Filariform)
Diagnostic stage: Eggs in Stool
Disease: Hookworm infection, Ancylostomiasis
Treatment :Scientist are trying to develop a vaccine using drugs such as Albendazole, Mebendazole, and Pyrantel Pamoate. BY Asmaa Sameer 90029 Under Supervision of Prof.Dr. Manal El Garhy Hyperchromic anemia Aplastic anemia is a blood disorder in which the body's bone marrow doesn't make enough new blood cells Anemia is a condition in which the body does not have a sufficient number of red blood cells or hemoglobin. Pernicious is a term that means destructive, injurious or deadly Species of plasmodium.
Hosts
Plasmodium spp. Require two types of hosts: an invertebrate (mosquito) and a vertebrate (reptile, birds, or mammal). Technically the invertebrate can be considered the definitive host because sexual reproduction occurs there. Asexual reproduction takes place in the tissues of a vertebrate, which thus can be called the intermediate host. However the gametocytes actually form in the blood of the vertebrate, and fertilization occurs while still in this medium in the stomach of the mosquito. By this reasoning the vertebrate is the definitive host.
Route of infection:
Via the bite of an infective female Anopheles' mosquito, which is the only species capable of transmitting malaria (protozoan) parasites.
Infective stage:
Sporozoite is the infective stage of Malaria.
Disease: malaria
Treatment :
Chloroquine attacks parasites that are circulating in the blood
For chloroquine-resistant strains of falciparum malaria For this resistant parasite, the drug mefloquine is the preferred and it is prevented with Genetically Engineered Bacteria Prevent Mosquitoes from Transmitting Malaria. Infective Stage: Plerocerus in raw or unercooked muscle of intermediate host.
Route of Infection: Oral
Intermediate host: Copepods (first intermediate host), fresh water fish (2nd intermediate host).
Reservoir Host:Bear, dog
Diagnostic Stage:Egg
Disease : diphyllobothriasis.
Treated with  Epsiprantel,  Praziquantel Reservoir hosts:are domestic animals such as the fox, jackal, rodents and wolves.
Vector : Phlebotomus mosquito (sand fly).
Disease : leishmaniasis.
Diagnosis :Demonstration of amastigotes(L. donovani bodies) in direct smears or promastigotes in culture of material from the liver, spleen, bone marrow, blood and lymph nodes
Treatment :developed paromomycin intramuscular injection (PMIM) as an effective, inexpensive, and safe treatment for VL Infective Stage:Cyst
Route of Infection:Oral
Intermediate Host:None
Disease : Giardiasis
Reservoir Host:Beaver, dog
Diagnostic Stage: Cysts and trophozoites
Method of diagnosis: Stool exam, duodenal aspirate, “string” test
Treatment: The most common treatment for giardiasis is metronidazole (Flagyl) Microcytic hypochromic
Anemia Hemolytic anemia Aplastic anemia Hyperchromic anemia Pernicious anemia Ancylostoma Plasmodium spp Diphyllobothrium latum Trichuris trichiura Leishmania Donovani Giardia Microcytic hypochromic
Anemia Ancylostoma Hemolytic anemia Plasmodium spp Macrocytic Hyperchromic anemia is a blood disorder characterized by abnormally large red blood cells which contain abnormally high amounts of haemoglobin. Aplastic anemia Pernicious anemia Giardia Leishmania Donovani Diphyllobothrium latum Infective Stage: Egg.
Route of Infection: Oral.
Diagnostic Stage:EggMethod of Diagnosis: Stool examination.
Disease: Trichurisis (Whipworm commonly infects patients also infected with Giardia, hookworms and others.)
Treatment: Mebendazole/Albenzadole Trichuris trichiura Thank You
