Simple spot test for rapid detection of urease activity.
A spot test for the detection of urease activity was developed and evaluated with 761 strains of gram-negative bacteria. The test was compared with the conventional Christensen urea agar slants and urease test on the Vitek Enterobacteriaceae card (Vitek Systems, Inc., St. Ana, Mo.). Of the 348 strains of the Proteus-Providencia-Morganella group that were urease positive, 327 (94%) yielded posit...
متن کاملUrease and Dental Plaque Microbial Profiles in Children
OBJECTIVE Urease enzymes produced by oral bacteria generate ammonia, which can have a significant impact on the oral ecology and, consequently, on oral health. To evaluate the relationship of urease with dental plaque microbial profiles in children as it relates to dental caries, and to identify the main contributors to this activity. METHODS 82 supragingival plaque samples were collected fro...
متن کاملInvestigation of H Pylori Colonization in Adenotonsillectomy Specimens by Means of Rapid Urease (CLO) Test
This prospective clinical study was performed to investigate the colonization of H pylori in adenoid and tonsil tissues by using the Campylobacter-like organism (CLO) test. Included in the study were 56 patients aged 3 to 43 yrs who had undergone adenoidectomy, tonsillectomy or adenotonsillectomy procedures under general anesthesia. Two-mm diameter tissue pieces of adenoid and tonsil specimens ...
متن کاملDetermination of Helicobacter pylori Antigen in Stool Samples and Comparison with Rapid Urease Test in Patients Suspected of Helicobacter Infection
Background and Aims: Helicobacter pylori (H. Pylori) is the microorganism that infects nearly half of word's population. There are several invasive and non-invasive methods for diagnosis of infection. The main objective of this study was to evaluate antigen of H. Pylori in feces with H. pylori stool antigen (HpSA) test and comparison with rapid urease test (RUT) in the patients suspected to be ...
