BACKGROUND Initial resistance to antibiotics is the main reason for the failure of Helicobacter pylori (H. pylori) eradication in children. OBJECTIVES As we commonly face high antibiotic resistance rates in children, we aimed to determine the susceptibility of H. pylori to common antibiotics. PATIENTS AND METHODS In this cross-sectional in vitro study, 169 children younger than 14 years wit...

There is a great need to detect gastrointestinal tract cancer at an early stage. It is well known that most carcinoma tissues of the gastrointestinal tract contain carcinoembryonic antigen (CEA). Stools are a rich source of cells derived from the gastrointestinal tract. We analyzed total fecal CEA in 60 gastrointestinal tract cancer patients, 20 benign gastrointestinal tract disorder patients, ...

An antigen-capture enzyme-linked immunosorbent assay employing rabbit and mouse antisera to Giardia lamblia cyst antigens was developed for the diagnosis of Giardia infection through detection of G. lamblia-specific stool antigens in cell-free aqueous eluates of human stool. This is the first report of the use of anti-cyst antibodies in an enzyme immunoassay for G. lamblia. The assay gave a pos...

We describe a case of ocular (subconjunctival) cysticercosis in a eighteen years old, vegetarian male, who presented to the ophthalmology OPD with complaints of increasing painless conjunctival swelling of left eye since four months associated with redness, restriction of gaze and diplopia. The patient had a history of similar swelling in tongue three months back, which extruded spontaneously. ...

Methods: A total of 1,123 adult subjects who participated in a health survey in Hirosaki City were studied. Infection of H. pylori was defined by both serum antibody and stool antigen test. The presence and the severity of atrophic gastritis were defined by the serum level of serum pepsinogens. Using 16S ribosomal RNA amplification from fecal samples, the relative abundance of Lactobacillus was...

Adult mites' bodies of Dermatophagoides farinae were used as antigen in an indirect fluorescent antibody test (IFAT) to detect mite-specific IgG in sera of 48 patients with intestinal acariasis based on stool examination. Antibody titers with positive reaction ranged from 1:4 to 1:512 in 48 patients with intestinal acariasis. If antibody titers > or = 1:16 is regarded as being positive, the pos...
