Necropsy studies were done on ten adult Filipinos, five women and five men, who died of intestinal Capillaria philippinensis infection. All of the bodies were severely emaciated and skin turgor was markedly reduced. Transudate was found in the pericardial, pleural, and peritoneal cavities. Large numbers of adults, larvae, and eggs of the parasite were found in the small bowel, particularly in the jejunum. The adults were partially embedded in the mucosa adjacent to the lumen. Larval forms were frequently near adults in the mucosa. Large numbers of the eggs, larvae, and adults were in the luminal fluid. Lesser numbers were found in the larynx, esophagus, and stomach but were not attached to the mucosa. The same was true for the colon. The parasite was also found near the portal areas in the liver in one case. Vacuolization of striated muscle indicative of hypopotassemia was present. Vacuolization of proximal renal tubular lining cells was also found.
