Eimeria falciformis

Eimeria falciformis is an obligate intracellular parasite that primarily infects the mouse species Mus musculus. As part of the Apicomplexa phylum, it has a complex life cycle within its host, causing tissue necrosis and inflammation, particularly in the cecum. This leads to coccidiosis, a disease characterized by symptoms like diarrhoea and weight loss. E. falciformis is one of over 1,700 species in the Eimeria genus, which infects the intestinal epithelial cells of various animals, including poultry and livestock.
