Sheep Parasites, is a key to identify both endo- and ecto-parasites in Australia and around the world. Developed by Muhannad Azeen SAEED and Abdul JABBAR at the University of Melbourne, Australia, Sheep Parasites enables users (veterinary students, practitioners, parasitologists and potentially farmers) to identify both endo-and ecto-parasites of sheep and goats that commonly occur in Australia and around the world. This key includes a comprehensive guide to morphological identification of at least 74 parasite genera/species including nematodes, trematodes, cestodes, protozoa, ticks, mites, lice and flies. Furthermore, a brief pointwise description of each parasite and associated disease together with photographs is provided in the App.
