Abstract

Abstract:

An 42-year-old male patient who was found to have a parasite in his ileocecal region during a colonoscopy examination in December 2021. The worm was reported motile and was removed with biopsy forceps. During the colonoscopy, no abnormality was found in the intestinal mucosa where the parasite was found and no abnormality was found in the intestinal lumen. The extracted parasite was identified as Anisakis simplex preliminarily by morphological identification. DNA was extracted from parasites and tested by PCR. The amplified fragment was about 1 000 bp. After sequencing, BLAST analysis showed that it was consistent with Anisakis simplex up to 99%. By phylogenetic tree analysis, it was clustered with Anisakis simplex. The parasite was confirmed to be Anisakis simplex. The patient reported that he had lived in southeast coastal cities for a long time and had a history of eating raw seafood products for many years. No discomfort was reported after the parsite was removed, so no other examination and treatments were performed.
