ISOLATED CRYPTOSPORIDIOSIS IN A HEALTHY YOUNG INDIVIDUAL

Abstract

We encountered a case of cryptosporidiosis in a man in his 20s with no medical history who developed right lower abdominal pain, fever, and diarrhea. Although the cause was unknown in the stool examination, Cryptosporidium protozoa were suspected in the ileum and colon biopsy tissue examination. The patient was diagnosed with cryptosporidiosis caused by Cryptosporidium parvum by polymerase chain reaction examination of the biopsy tissue. In cases in which abdominal symptoms, such as diarrhea, are severe and long-lasting for mere viral enteritis, it is important to conduct a detailed interview about the patientʼs life history, remember parasitic diseases, including this case, perform additional stool tests (acid-fast bacteria staining and sucrose centrifugal flotation method), and conduct thorough examinations, such as endoscopy, together with a pathologist.
