Finally, five strains of Lactobacillus and one Bifidobacterium strain as natural microbial flora from Lavark samples, 4 strains of lactobacillus from jug cheese and one Lactobacillus strain from Mar 01, 2012 · Bifidobacterium species are difficult to identify and may be underreported or not recovered by many laboratories because of their slow growth. We emphasize the importance of the Gram stain in urine samples and the addition of enriched media and enhanced atmosphere over time for urine cultures with pyuria. This is the first report of a Bifidobacterium scardovii recurrent urinary infection in …

    Jan 29, 2007 · Therefore, the objective of this study was the development of a rapid and easy to perform identification and detection system based on PCR analysis (PCR, ARDRA, RAPDs) with the ability to differentiate among Lactobacillus, Streptococcus and Bifidobacterium species related to dairy products. Also, the objective of this study was to choose the identification of lactobacilli. However, due to the large number of species, application of sole genotypic methods is quiet difficult. Therefore, Traditional biochemical tests are still used as an important tool for identification and classification of lactobacilli[19]. This study aims at …

    Aims: To evaluate the full test scheme of 3 for the identification of clinical enterococcal isolates to genus and species level. Methods and Results: Fifty‐nine clinical isolates, previously provisionally classed as enterococci on the basis of just four biochemical tests of Facklam and Sahm and one other test, were subjected to genus and species identification using the full identification 11 BACTERIAL IDENTIFICATION TESTS 11.1 INTRODUCTION mentioned below so as to identify the bacteria zStaining of the isolated bacteria Biochemical tests The staining is followed by use of various biochemical reagents and tests to get closer to the identification of …
