Parasitic eggs and oocysts found in faeces of alpacas with the use of flotation techniques (400 × magnification, bar = 12 μm) 2A – an egg of the Trichostrongylidae family; 2B – an oocyst of the Eimeria genus; 2C – an egg of the Nematodirus genus; 2D – an egg of Nematodirus battus; 2E – an egg of the Aonchotheca genus; 2F – an egg of the Trichuris genus; 2G – an oocyst of Eimeria macusaniensis; 2H – eggs of the Moniezia genus
