Research ArticleOpen accessEvery word in the titleISOLATION AND DETECTION OF HELICOBACTER PYLORI FROM PATIENTS SUFFERING FROM PEPTIC ULCER USING BIOCHEMICAL TESTS AND MOLECULAR TECHNIQUESRuba S. Abu-Sbeih, Azmi D. Hawari, Dhia S. Hassawi, Hala I. Al-DaghistaniHelicobacter pylori is the causative agent of most cases of gastritis. There is no established gold standard for the diagnosis of H. pylori infection. A reliable diagnosis is crucial to confirm that eradication therapy has been successful. Eighty gastric biopsy and blood samples were obtained from fasting Jordanian patients with Esophago-Gastro-Doudenoscopy (EGD). Several diagnosis tests for H. pylori infections were … …American Journal of Biochemistry and Biotechnology, Vol. 10, Issue 1 · 28 Mar 2014 · 8,183 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleSELECTIVE ISOLATION OF A GRAM NEGATIVE CARBAMATE PESTICIDE DEGRADING BACTERIUM FROM BRINJAL CULTIVATED SOILDilara Islam Sharif, Mithun MollickA bacterial species having the ability to grow in the presence of carbosulfan pesticide “Marshall” was isolated from Solanum melongena (brinjal) cultivated soil in Khulna region, Bangladeh, having a history of pesticide usage. The strain was morphologically and biochemically identified to belong to the genera Pseudomonas. A comparative study of growth of this strain with other isolated bacteria showed its … …American Journal of Agricultural and Biological Sciences, Vol. 8, Issue 4 · 24 Sep 2013 · 7,448 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleIsolation of the Antimicrobial Cyclic Peptide Subtilosin a from a Gut-Associated Bacillus subtilis StrainGhislain Schyns, Claudia R. Serra, Adriano O. Henriques et al.The endospore-forming Bacillus subtilis has been used as probiotics over the last 50 years. However, little is known on how Bacillus spp act in the gut compared to other well-characterized probiotics such as lactic acid bacteria. It is believed that the competitive exclusion of pathogens results from different mode of action notably the production of antimicrobial compounds such as bacteriocins. … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 3 · 21 Sep 2013 · 7,678 accessesView PDFCite
Research ArticleOpen accessEvery word in the titleISOLATION AND CHARACTERIZATION OF HELICOBACTER PYLORI STRAINS FROM GASTRIC BIOPSIES OF ALGERIAN PATIENTSGuetarni Hassina, Bensoltane AhmedThe objective of this study is to isolate and characterize strains Helicobacetr pylori from gastric biopsies by upper gastrointestinal endoscopy. After a rapid urease test, two Helicobacter pylori strains isolated from four patients on blood agar. After extraction of DNA from these strains from homogenates of gastric biopsies, quantification by real-time PCR was performed to determine Helicobacter pylori on the … …OnLine Journal of Biological Sciences, Vol. 13, Issue 2 · 19 Apr 2013 · 7,264 accessesView PDFCite

Naresh KumarProblem statement: Gastrointestinal disorders mainly diarrhea is the most common cause of morbidity and mortality among infants and children in the developing countries occurs due to infection by enteropathogens. Ccontrol of these pathogens could be achieved by nonpathogenic Escherichia coli producing bacteriocins. Approach: Primary aim of this study was to isolate E. coli strains which inhibit enteropathogens. For this purpose, … …American Journal of Infectious Diseases, Vol. 5, Issue 2 · 30 Jun 2009 · 8,417 accessesView PDFCite
