List the intermediate hosts for the following pathogens: Taenia solium, Taenia saginata, Fasciola haematobium, Plasmodium falciparum, Trypanosoma brucei, Onchocerca volvulus.

Here are the intermediate hosts for the given pathogens:

i. Taenia solium: The intermediate host is the pig.
ii. Taenia saginata: The intermediate host is cattle.
iii. Fasciola haematobium: Assuming this is a typo and refers to Schistosoma haematobium (a common human blood fluke), the intermediate host is a freshwater snail (e.g., Bulinus species). If it strictly refers to Fasciola (liver fluke), the intermediate host is also a freshwater snail (e.g., Lymnaea species). Given the context of human pathogens, Schistosoma haematobium is more probable.
iv. Plasmodium falciparum: The intermediate host is the female Anopheles mosquito.
v. Trypanosoma brucei: The intermediate host is the tsetse fly.
vi. Onchocerca volvulus: The intermediate host is the blackfly (genus Simulium).
