It was found that the morphological changes which occur with longer incubation of H pylori have an inverse correlation with its resistance to an acidic environment. The finding that the addition of urea almost reversed thi...

متن کاملVacuolating Cytotoxin of Helicobacter pylori
Vacuolating cytotoxin (VacA) is one of the most important virulence factors of H. pylori (Hp), which isthe only toxic protein that is secreted from Hp cell into the culture supernatant. The effects of VacA oneukaryotic systems is the subject of many previous and on going research studies. Intracellular targetsfor this toxin include: late endosomal and lysosomal compartments, m...
متن کاملPackaging method for preserving agar plates during prolonged incubation.
In this report, we describe a simple packaging method which can be used to preserve either normal or salt-agar plates during prolonged incubation. In our search for halophilic microorganisms from Indonesian "Pindang," consisting of boiled and salted fish (S. Iljas and L. J. Ronsivalli. Fishery Ind. Res., in press), it was evident from the literature (2) that prolonged incubation might be necess...

During a period of 10 months from May to February 1995, 120 children (72 girls, 48 boys) with an age range of 4-16 years (mean age 10.87, S.D.±2.7) with chronic abdominal pain who had an abnormal endoscopy (gastroduodenal mucosal defect) and positive urease test were treated for H. pylori. Patients were treated randomly with either metronidazole and amoxicillin (double therapy, group A) or ...
