The aim of this study was to validate the rapid lateral flow Helicobacter pylori stool antigen test (One step H. pylori antigen test, ACON laboratories, San Diego, USA; Prime diagnostics, São Paulo), using 13C-Urea Breath Test as the gold standard for H. pylori infection diagnosis. A total of 98 consecutive patients, asymptomatic or dyspeptic, entered the study. Sixty-nine were women, with a me...

INTRODUCTION The Bristol Stool Form Scale (BSS) which consists of 7 photographs of different stool forms allows assessment of stool consistency (scale 1 for hard lumps to scale 7 for watery stools), in an objective manner in adults. The BSS is also sometimes used to characterise the stools of infants and young children. Despite its use, there is general agreement among paediatric gastroenterolo...

15N from labelled yeast protein, fed to marasmic and recovered infants, appeared in the stool shortly after administration and continued to be excreted for 100 hours. Unabsorbed dietary 15N, which appeared with carmine-marked stools, formed only part of this excretion. Calculations of the endogenous nitrogen content of infant stool agreed closely with those of previous workers. The use of intra...

During one year study, 394 stool samples obtained from a random cases of diarrhea were examined for the presence of free shiga-like toxins Stx1 and Stx2 in Vero cells assay. Of 394 stool specimen supernatants tested, 2 (0.5%) gave positive results. The two stool supernatants positive on Vero cell line were wholly capable of being neutralized with the monoclonal antibody to Stx2. Broth cultures ...
