Reliable urease test for identification of mycobacteria.
A simple, modified formation for urea broth gave consistent, reliable results to aid in the differentiation of Mycobacterium species. In a study of 1,346 isolates representing 17 different species, tests read after 7 days were distinct and reproducible. The use of this test facilitates the identification of Mycobacterium species, such as M. scrofulaceum, the M. avium complex, the M. terrae comp...

متن کاملCurrent tuberculosis diagnostic tools & role of urease breath test
Tuberculosis (TB) remains a significant public health issue worldwide especially in developing countries, where the disease is endemic, and effective TB diagnostic as well as treatment-monitoring tools are serious barriers to defeating the disease. Detection of pathogen-specific metabolic pathways offers a potential alternative to current methods, which focus on bacterial growth, bacterial nucl...
متن کاملSimple 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...
