kdikysts
kdikysts are a rare class of parasitic cysts that appear predominantly in the hepatic and splenic tissues of mammals. They are formed by the obligate intracellular organism Kdikystis major, a single-celled protozoan belonging to the phylum Apicomplexa. Although they were first reported in 1998 in a small population of captive felids, subsequent studies have documented cases in canines, rodents, and occasionally humans.
The life cycle of K. major involves an intermediate host where the organism undergoes merogony and gametogony,
Diagnosis relies on serological testing for K. major antibodies and imaging studies such as ultrasound or CT
