Study Notes

Amebic Dysentery

Amebic dysentery is a disease caused by dirty hands.
The causative agent of amebic dysentery is Entamoeba dysenteriae.
Entamoeba dysenteriae is a protozoan.

Leishmaniasis

Leishmania Donovani is the causative agent of visceral leishmaniasis.
The vector for Leishmania Donovani is Phlebotomus.
Leishmania tropica is the causative agent of cutaneous leishmaniasis.
Leishmania is cultured on NNN agar.

Trypanosomiasis

Trypanosoma Gambiense Duton causes sleeping sickness.
The vector for Trypanosoma Gambiense Duton is Glossina palpalis.
The vector for Trypanosoma Rhodesiense is Glossina morsitans.
The vector for Trypanosoma Cruzi is Triatoma megista.

Trichomoniasis

Trichomoniasis is transmitted by coitus.
Trichomonas vaginalis is cultured on Löffler's medium.

Giardiasis

Giardia Lamblia can cause diseases such as hepatitis, osteoporosis, psychosis, and pregnancy.

Malaria

Malaria is caused by Plasmodium vivax, Plasmodium malariae, and Plasmodium falciparum.
Plasmodium vivax causes Tertian malaria.
Plasmodium malariae causes Quartan malaria.
Plasmodium falciparum causes Tropical malaria.
Malaria is transmitted by mosquitoes of the genus Anopheles.
During Tropical malaria, sudden spikes in temperature occur every 24-48 hours.
During Tertian malaria, sudden spikes in temperature occur every 48 hours.
During Quartan malaria, sudden spikes in temperature occur every 72 hours.
Malaria diagnosis is made by detecting parasites in the blood.

Toxoplasmosis

Toxoplasma gondii is a protozoan.
Diagnosis of toxoplasmosis is made by ELISA test.
Toxoplasma gondii has an affinity for embryonic cells.

Dicrocoelium lanceolatum and Fasciola hepatica

Dicrocoelium lanceolatum is a small fluke.
Dicrocoelium lanceolatum parasitizes in liver and bile ducts.
Fasciola hepatica is a large fluke.

Schistosomiasis

Schistosoma haematobium belongs to trematodes.
Schistosoma haematobium is a parasite of abdominal vein.
Schistosoma mansoni is a parasite of colon vein.
Schistosoma japonicum is a parasite of portal vein system.
Humans are infected with Schistosoma mansoni by larval penetration through the skin.
