Why use crystal violet agar?
Crystal violet agar is a selective medium used for isolating and differentiating gram-positive bacteria from mixed cultures. The crystal violet dye inhibits the growth of gram-negative bacteria, allowing the gram-positive bacteria to grow and form distinct colonies. This agar can be useful in differentiating bacteria in clinical samples or environmental samples.
What is the name of the technique where human insulin is created from bacteria?
Recombinant DNA technology
How should specimens for anaerobic bacteria culture be transported to the lab?
Tissue samples should be placed into a degassed bag and sealed, or into a gassed out screw top vial that may contain oxygen-free prereduced culture medium and tightly capped. The specimens should be plated as rapidly as possible onto culture media
What is the type of cell found on human blood that uses this technique for capturing and destroying bacteria?
leukocyte
What are the types of specimens tested in the microbilogy department?
Many specimens are tested there. As the name says microbiology is where they research micro-species, like bacteria, or amoebas. The tests usually look for specific resistance or reactions to drugs. Of course there are many other research types.

What anaerobic bacteria found in stool specimens is the etiological agent pseudomembranous colitis?
Clostridium difficile
How do you count bacteria using aseptic technique?
dcsddsdsds
What 5 specimens that can be enlarged when drawn in laboratory paper?
Specimens that can be enlarged when drawn on laboratory paper include bacteria, fungi, blood cells, parasites, and plant cells. These specimens can be magnified through a microscope for closer observation and analysis in the laboratory setting.
What types of organisms are subjected to Negative Staining Technique?
Bacteria .
How is pollution fought with bacteria?
Bacteria have been developed that can metabolize (eat) many pollutants.
What technique is used to make bacteria that produce drugs?
recombinant technology
What is romanoskystain?
Romanowsky staining was a prototypical staining technique that was the forerunner of several distinct but similar methods, including Giemsa, Jenner, Wright, Field, and Leishman stains, which are used to differentiate cells in pathologic specimens. A group of eosin-methylene blue stains generally used for blood smears, protozoa and bacteria.
Why is sterile technique importance?
to prevent contamination and to protect your self from harmful bacteria .
What is the name of the technique where human insulin is created from bacteria?
Recombinant DNA technology
How would you describe the gram stain?
Describe the Gram stain technique and the effect on Gram-positive and Gram-negative bacteria after each step. Be very specific about what is happening at each step and why it happens. (hint: be sure to fully explain your answer and not just list the steps)
