1. This protozoal gut infection often causes diarrhoea.

2. Sections were examined by light microscopy for bacterial, protozoal, fungal, and viral enteric pathogens.

3. Neosporiasis is one kind of protozoal disease, which trouble many kinds of domestic animals; this disease is very serious especially for cattle.
