AIMS To ascertain the present practices of Scottish microbiological laboratories for examining faecal samples for Cryptosporidium spp and to compare these with practices elsewhere. METHOD A questionnaire was circulated to all 35 Scottish NHS bacteriological laboratories, where human stool samples are subjected to routine microbiological examination, to determine current laboratory testing met...

The detection of Fasciola antigen in serum or stool could be more valuable in diagnosis, hence early treatment before irreparable damage. In this study, fresh adult Fasciola gigantica worms were collected, then incubation in culture medium and collected medium was used to extract crude excretory-secretory (E/S) antigen. E/S was used to immunize rabbits to raise specific antibodies against Fasci...

The diagnosis of the small (4- to 6-microns) Cryptosporidium oocysts is labor intensive and relies on stool concentration, with subsequent staining and microscopy. The primary purpose of this study was to evaluate the clinical utility of an antigen capture enzyme-linked immunosorbent assay (ELISA) (LMD Laboratories, Carlsbad, Calif.) in detecting Cryptosporidium oocysts in human stools. A total...

The aim of this study was to evaluate the efficacy of a polymerase chain reaction (PCR)-based method to detect Schistosoma mansoni DNA in stool samples from individuals living in a low-endemicity area in Brazil. Of the 125 initial stool samples, 80 were ELISA reactive and eggs were identified in 19 of the samples by parasitological examination. For the PCR evaluations, 56 stool samples were sel...

The lack of a quick, simple, and inexpensive diagnostic test has limited the ability of public health officials to rapidly assess and control outbreaks of Giardia lamblia in child day-care centers. We evaluated the performance of a commercially available enzyme-linked immunosorbent assay (ELISA) for the detection of a G. lamblia-associated antigen in stool. Stool specimens were collected from t...

Examination of samples of stool from a 61-year-old male patient, presenting with the clinical symptoms of Crohn's disease (CD), revealed massive shedding of acid fast bacilli with the morphology of Mycobacterium avium paratuberculosis (MAP), the causative agent of Johne's disease in cattle. MAP was cultured from the stool. Biotyping of the bacterium isolated from cultures of stool demonstrated,...

Hookworm infections are widely prevalent in tropical and subtropical areas, especially in low income regions. In the body, hookworms parasitize the proximal small intestine, leading to chronic intestinal hemorrhage and iron deficiency anemia. Occasionally, hookworms can cause overt gastrointestinal bleeding, but this is often ignored in heavily burdened individuals from endemic infectious areas...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014204968 DESCRIPTION An 89-year-old woman with a known history of diverticulitis presented to our emergency department (ED) with a few days’ history of haematochezia. She had decided to seek medical help after having a severe episode of bloody stool and feeling dizzy. Her vi...

A 45 years old non-diabetic normotensive male presented with vomiting, watery diarrhoea and fever of acute onset. On examination, he was febrile, toxic and mildly dehydrated. His pulse was llO/min and blood pressure 96/70 mmHg. The abdominal examination revealed no organomegaly, no distension, vague diffuse tenderness on deep palpation and normal bowel sounds. There was no other abnormality det...

deficiency anemia had a medical examination in May 2002. She was diagnosed as having anisakiasis after upper endoscopy of the antrum of the stomach, and a worm was removed. Three years later, an upper endoscopy showed several worms in the first and second portions of the duodenum, but there were no symptoms. Ten live worms were removed using standard biopsy forceps and were identified by micros...
