Answer 8

Fendendazole (most common; metronidazole; furazolidone; nitazoxanide

Question 9

Answer 9

Metronidazole; Ronidazole; Clioquinol

Question 10

Answer 10

Imidocarb diproprionate (Imizol), pretreatment with atrophine important. Works better against B. canis; Atovaquone and azithromycin can be used to treat carrier state

Question 15
