Here’s why knowing whether the result is … Microbiology Program. Gram-positive bacteria are bacteria with thick cell walls. Bacterial. I challenge you to score more than 60% on this quiz! Interpret various microbiology test results. Biochemical reactions are very important in the identification of bacterial isolates and in the identification of different bacterial species. Supporting Laboratory Results. 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. Infectious Diseases. Identification of bacteria. The bacteria that are typically present and on the surface of the human body, and which are typically harmless or even helpful to humans are called the "_____" microbiota A. endemic B. normal In a Gram stain test, these organisms yield a positive result. Fungal. This challenging biology test on cells is designed to test your knowledge on this topic to the extremes. A urine culture is a test that can detect bacteria in your urine. Summarize antibiotic susceptibility testing and results. Rapid identification of gram-negative bacilli of the family Enterobacteriaceae isolated from clinical specimens has long posed a problem for the clinical laboratory. 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 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 test can find and identify the germs that cause a urinary tract infection (UTI). Bacterial. Good Luck with this quiz! A cell is the basic fundamental unit of all biological organisms.
