In addition to the use of selective and differential media, biochemical tests are used in clinical microbiology labs to help identify bacteria in specimens. Catalase and oxidase tests are both examples of common biochemical tests used to help identify clinically signific...
have been identified as particularly important dietary contributors to dental caries14. Consumption of sweetened foodstuffs can rapidly increase the concentration of carbohydrates in the oral cavity, leading to a sharp decline in the pH values of biofilm to 4 or even lower15. Research has revealed...

All five “I’s” of Microbiology were used in the testing for the unknown culture. Inoculation was used several times to put the unknown culture into agar plates or into biochemical test tubes. After Inoculation of these tubes or plates, they always were placed into the incubator for further...
The family of Micrococcaceae includes Gram-positive, aerobic, cocci, non-spore forming, non-motile and positive reactions to catalase, coagulase, deoxyribonuclease test and plays a relevant role in fermentation. The species of Micrococcus and Staphylococcus (S. aureus) are reported in fermenting tra...

In the last decades, tremendous advancement in dissecting the mechanisms of pathogenicity ofNeisseria meningitidisat a molecular level has been achieved, exploiting converging approaches of different disciplines, ranging from pathology to microbiology, immunology, and omics sciences (such as genomics and pr...
a. fungus b. virus c. gram-negative bacterium d. mite What is one virulence factor that differentiates Staphylococcus aureus from other species of staphylococci? A) It has a capsule. B) It can produce coagulase. C) It produces catalase. D...
1. How are solid tissue samples prepped for (a) LM, (b) TEM, (c) SEM? 2. What are the differences between LM and TEM tissue preparations(steps, dimensions, staining)? Important Terms: LM - Light microscope....
