The main purpose of the study is to determine resistance pattern of bacterial isolates to selected antibiotics among 88 dyspeptic patients in Iran. Frequency of infection among these patients have been evaluated among dyspeptic patients old (45 boys and 43 girls, aged 5-18 years) from 2016 to 2017.Eighty-eight patients with gastroduodenal disorders were included in the study. Urease test modifi...

Campylobacter pyloridis is strongly associated with the presence of histological gastritis,1 2 but its role in the aetiology of peptic ulcer disease and non-ulcer dyspepsia has yet to be determined. Its detection in antral mucosal biopsy specimens usually entails histo-logical or microbiological methods that may require several days for a result. In a previous study3 we found that direct examin...

With black soil (Pachic Udic Argiboroll) of Northeastern China as the test object, an incubation test was conducted to investigate the effects of urease inhibitors, hydroquinone (HQ), phenyl phosphorodiamidate (PPD) and N-(n-Butyl) thiophosphoric triamide (NBPT), on the kinetic characteristics of soil urease under normal moisture and waterlogged conditions, aimed to study the changes of catalyt...

background and objectives: tuberculosis (tb) is a major problem in the world. treatment and control of tb needs detection of the mycobacterium tuberculosis (mt) in the proper samples. while smear doesn’t have enough sensitivity, culture and pcr are expensive, time consuming and unavailable in many centers. recent development of a rapid tb antigen detection test (prtbk) at pasteur institute of i...

Campylobacter pylon or campylobacter like organisms (CLO) are curved bacilli which are found on the gastric mucosa of patients suffering from gastritis, peptic ulceration and other related diseases. These organisms were later renamed as helicobacter pylori. The diagnosis of HP is usually made on histology, culture, urease tests and serology. Although all these tests are 60-100% sensitive and sp...

Helicobacter pylori urease, a nickel-requiring metalloenzyme, hydrolyzes urea to NH3 and CO2. We sought to identify H. pylori genes that modulate urease activity by constructing pHP8080, a plasmid which encodes both H. pylori urease and the NixA nickel transporter. Escherichia coli SE5000 and DH5alpha transformed with pHP8080 resulted in a high-level urease producer and a low-level urease produ...

this study was performed to detect cultivable canine gastric helicobacter-like organisms (ghlo’s) and to evaluate their sensitivity to common antibiotics in two groups of naturally infected dogs (pets and stray dogs). gastric samples were taken from the body and antrum of 30 pets and 30 stray dogs. from each part of canine gastric mucosa, four gastroscopic samples were used for impression smear...

To identify the correlation between the number of gastric biopsy samples and the positive rate, we compared the results of urease test using one and three biopsy samples from each 255 children who underwent gastroduodenoscopy at Gyeongsang National University Hospital. The children were divided into three age groups: 0-4, 5-9, and 10-15 yr. The gastric endoscopic biopsies were subjected to the ...

background: the main purpose of the current study was to determine the effect of treating helicobacter pylori (hp) infection on seizure frequency in patients with refractory epilepsy. methods: a small sample of adult patients above 18 years of age with a diagnosis of refractory epilepsy was studied at the outpatient epilepsy clinic at shiraz university of medical sciences, from january 2009 thr...
