Detection of verotoxin in stool specimens.
A total of 132 fecal specimens containing verotoxin (VT) were subjected to counter-current immunoelectrophoresis (CIE). Of these, 113 (85.6%) were found to be positive by CIE. Another 71 stool specimens containing E. coli serogroup O157 but with flagellar antigens other than H7 were tested for verotoxin by CIE. These stool specimens were negative for VT on Vero cell monolayers. Of these 71 stoo...
متن کاملDetection of Opisthorchis viverrini in human stool specimens by PCR.
Opisthorchiasis is a liver fluke infection, found mainly in Southeast Asia (8) but increasingly in developed countries due to an influx of Asian immigrants (7). The diagnostic methods are based on the demonstration of eggs in stools, although there are still difficulties in distinguishing eggs from heterophyid and lecithodendriid parasites (2). We have successfully developed a PCR-based method ...
متن کاملDetection of Helicobacter pylori in stool specimens: comparative evaluation of nested PCR and antigen detection.
BACKGROUND Efficacy of Helicobacter pylori stool antigen enzyme immunoassay (HpSA) and stool PCR was evaluated, before and after treatment, in a country with a high prevalence of H. pylori infection. METHODOLOGY A total of 52 patients with dyspeptic symptoms were included in the study. Antral biopsy was collected during pre- and post-therapy periods for rapid urease test (RUT) and PCR. Simila...
متن کاملHaemorrhagic colitis: detection of verotoxin
Faeces (n = 1319) were examined over three months for the presence of non-sorbitol fermenting, verotoxin producing Escherichia coli (serotype 0157). Seven isolates were found, four from patients with bloodstained diarrhoea and three from patients with no evidence of blood in the faeces. Screening of all faecal samples with specific 0157 antiserum for non-sorbitol fermenting organisms and agglut...
متن کاملdevelopment of an arcaga antigen-based assay for the detection of helicobacter pylori in stool specimens
conclusions based on the findings, application of recombinant arcaga antigen for the detection of h. pylori infection is a simple, rapid, and brief non-invasive method. therefore, it can be suggested as an appropriate antigen for h. pylori detection kits. results we investigated caga protein, using the immunoblotting method in stool samples, which were already identified as positive by the appl...
