"ghost" forms of giardia lamblia cysts initially misdiagnosed as isospora.because of their distinctive morphology the cysts of giardia lamblia usually are not mistaken for cysts or eggs of other intestinal parasites. at a hospital laboratory in kentucky a case of giardiasis was encountered in which the initial fecal examination revealed only degenerated cysts of giardia which were mistaken for the oocysts of isospora at the one-sporoblast stage.1978686251
prepatency of giardiasis.recently acquired giardiasis was suspected in 199 patients because of typical symptoms following a trip to a known endemic area. in 130 cases giardiasis was confirmed by stool examination, although most of the samples obtained less than 3 wk after probable infection were negative for giardia lamblia. prepatency was documented in 35 patients who, after one or more negative stool examinations, started to excrete giardia. the median prepatent period was 14 days, and in most cases the prepatent peri ...197768190
diagnosis of giardia lamblia infection as a cause of diarrhoea.retrospective analysis of the records of 31 patients diagnosed as having giardia lamblia infection in our hospital over a five-year period suggests that the condition is not considered often or early enough. adult patients particularly "suffer" more, having to endure more investigations (mean of 16) than do symptomatic children (mean of 6) before a diagnosis is made. the length of time to reach the diagnosis from first referral further supports this view, being almost seven weeks in adults and t ...197662176
effects of local delayed hypersensitivity on the small intestine.there are many t and b cells in the small intestinal mucosa and local t cell immunity could have a role both in protective immunity and as a cause of disease (i.e. hypersensitivity). this latter aspect has been investigated by using several animal models to assess the effects of local delayed hypersensitivity on the structure and function of the small intestine. heterotopically transplanted grafts of fetal small intestine in mice (isografts and allografts) have been examined by conventional hist ...197725166
