Increased WBC Count. Parasitic. Gram-positive bacteria are bacteria with thick cell walls. Oxidative/fermentation glucose test (OF glucose test) is a biological technique utilized in microbiology to determine the way a microorganism metabolizes a carbohydrate such as glucose (dextrose). This challenging biology test on cells is designed to test your knowledge on this topic to the extremes. Bacterial. Fungal. 207 Science Hall 2237 Osborn Dr. Ames, IA 50011. Infectious Diseases. The Gram stain is a test used to identify bacteria by the composition of their cell walls, named for Hans Christian Gram, who developed the technique in 1884. Compare various serological test results. Biochemical Test of Bacteria. Phone: 515-294-1630 Contact us: microundergrad@iastate.edu June 11, 2017 Nisha Rijal Bacteriology, Microbiology for Beginners 12 Most Probable Number (MPN) is a method used to estimate the concentration of viable microorganisms in a sample by means of replicate liquid broth growth in ten-fold dilutions. Malonate test is a colorimetric test of the ability of bacteria to use malonate as a source of carbon, the endpoint of which is the production of alkaline metabolites that induce a color change. Bacterial. These tests depend on the presence of certain enzymes, such as catalase, oxidase, urease, gelatinase, etc., produced by the bacteria. In a Gram stain test, these organisms yield a positive result. This test can find and identify the germs that cause a urinary tract infection (UTI). Bacteria: DNA in most is circular; bidirectional replication from single origin & replication fork is where DNA is unwound Archaea: circuar but may have more than one origin Eukaryotic: linear chromosome w/ many replication forks Supporting Laboratory Results. Viral. OF-glucose deeps contain glucose as a carbohydrate, peptones, bromothymol blue indicator for Hugh-Leifson's OF medium or phenol red for King's OF medium, and 0.5% agar. Objectives To test the ability of the organism to utilize malonate as sole source of carbon and energy for growth. Microbiology Program. Overview. Interpret various microbiology test results.
