“…Although most worms are found in the jejunum, some are found throughout the digestive tract, probably as a result of postmortem migration. The parasite was found once in extraintestinal tissue, in a section of liver (18).…”

Intestinal capillariasis caused by Capillaria philippinensis appeared first in the Philippines and subsequently in Thailand, Japan, Iran, Egypt, and Taiwan, but most infections occur in the Philippines and Thailand. As established experimentally, the life cycle involves freshwater fish as intermediate hosts and fish-eating birds as definitive hosts. Embryonated eggs from feces fed to fish hatch and grow as larvae in the fish intestines. Infective larvae fed to monkeys, Mongolian gerbils, and fish-eating birds develop into adults. Larvae become adults in 10 to 11 days, and the first-generation females produce larvae. These larvae develop into males and egg-producing female worms. Eggs pass with the feces, reach water, embryonate, and infect fish. Autoinfection is part of the life cycle and leads to hyperinfection. Humans acquire the infection by eating small freshwater fish raw. The parasite multiplies, and symptoms of diarrhea, borborygmus, abdominal pain, and edema develop. Chronic infections lead to malabsorption and hence to protein and electrolyte loss, and death results from irreversible effects of the infection. Treatment consists of electrolyte replacement and administration of an antidiarrheal agent and mebendazole or albendazole. Capillariasis philippinensis is considered a zoonotic disease of migratory fish-eating birds. The eggs are disseminated along flyways and infect the fish, and when fish are eaten raw, the disease develops.

“…A definitive diagnosis of gastrointestinal capillariasis is made by identifying eggs or adults in stools, biopsy specimens of infected organs, or by autopsy (1, 7). In the present case, worms were found to have characteristic stichosome in esophageal sections.…”

“…Adult C. philippinensis worms in the human digestive tract are usually found in the mucosa of the small intestine from the lower third of the duodenum to the proximal third of the ileum, and although they have been found in the luminal fluid of the larynx, esophagus, stomach, and colon this was attributed to postmortem migration (7). Therefore, true gastric capillariasis has not been reported in man.…”

A Case of Gastritis Associated with Gastric Capillariasis

et al. 2009

This report is about the case of gastritis associated with capillariasis. The patient was a 52-yr-old Korean woman who occasionally ate raw fish and chicken. She complained of mild abdominal pain and nausea, but not diarrhea. An endoscopic examination revealed an exudative flat erosive change on the gastric mucosa of the antrum. She was microscopically diagnosed as chronic gastritis with numerous eosinophil infiltrations. The sectioned worms and eggs in mucosa were morphologically regarded as belonging to the genus Capillaria. This is the first case of gastric capillariasis reported in the Republic of Korea.
