parasitic infections (thing)

In humans these can be divided into two groups: protozoa (all the single-celled parasites) and metazoa (multicellular parasites)

The common parasites are:

Protozoa

• Plasmodium - vivax, falciparum, ovale (malaria)
• Leishmania (Kala-azar)
• Trypanosoma (Chagas' disease, sleeping sickness)
• Giardia intestinalis
• Trichomonas vaginalis
• Cryptosporidia, Cyclospora, Isospora, Microsporidia, Blastocystis, Dientamoeba
• Entamoeba histolytica (amoebiasis)
• Toxoplasma gondii (toxoplasmosis)
• Acanthomoeba, Naegleria (amoebic meningitis)
• {Pneumocystis} (actually more a fungus than a protozoan)

Metazoa
Nematodes (Roundworms)
Tissue nematodes:

• Wucheria
• Brugia (filariasis)
• Onchocerca (river blindness)
• Loa loa
• Toxocara (visceral larva migrans)
• Angiostrongylus (eosinophilic meningitis)
• Trichinella

• Enterobius (pinworm)
• Trichuris (whipworm)
• Ancylostoma
• Necator (hookworm)
• Ascaris
• Strongyloides

Cestodes (Tapeworms)

• Taenia solium - pork (cysticercosis)
• Taenia saginata - beef
• Echinococcus (hydatid)
• Diphyllobothrum

Trematodes (Flukes)

• Schistosoma - haematobium, japonicum, mansoni (schistosomiasis)
• Clonorchis and Opisthorchus (liver fluke)
• Paragonimus (lung fluke)

not an exhaustive list, of course.
