We evaluated an antigen-based stool assay as an indicator of Helicobacter pylori (Hp) status during treatment aimed at eradicating Hp in 22 Hp-positive patients and 63 negative control patients. The sensitivity and specificity of the assay was 100% and 70%, respectively, when the manufacturer's cutoff was used. When we used the cutoff calculated from a receiver operating characteristic curve, the specificity of this test increased. Under these conditions, the test could be used in monitoring treatment and verifying eradication of Hp infection. Further studies must be carried out to standardize the cutoff in children.

This case report presents a rare occurrence of Sarcina ventriculi in a 15-year-old male patient with a clinical history of renal failure due to chronic rejection status post kidney transplantation, with persistent symptoms of diarrhea, nausea, vomiting, and fatigue. Despite exhibiting normal gastrointestinal mucosa upon endoscopy, biopsy analysis revealed chronic gastritis accompanied by the presence of Sarcina ventriculi in a tetrad arrangement across the stomach, duodenum, and distal esophagus. Interestingly, immunohistochemistry (IHC) staining targeting the Helicobacter pylori organism (H.

Introduction: Contamination of drinking water by can cause serious diseases, including cancer. The determinants of the infection rate are socioeconomic status, low standard of living and overcrowding. In addition, exposure to environmental sources contaminated with feces, such as water and vegetables, is another risk factor for infection.

Protein glycosylation has been considered as a fundamental phenomenon shared by all domains of life. In , glycosylation of flagellins A and B with pseudaminic acid have been rigorously confirmed and shown to be essential for flagella assembly and bacterial colonization. In addition to flagellins, several other proteins including RecA, AlpA/B, and BabA/B in have also been reported to be glycosylated and to be dependent on the lipopolysaccharide (LPS) biosynthetic pathway.

Objectives: Fecal calprotectin (FC) is a marker commonly used in the diagnosis and follow-up of inflammatory bowel diseases (IBD). However, other gastrointestinal conditions, like H. pylori (HP) infection, can result in increased neutrophil activity as well.
