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?
Specimens for anaerobic bacteria culture should be transported in an anaerobic transport system or container to maintain an oxygen-free environment. The specimens should be kept at room temperature and transported quickly to the lab to prevent the growth of aerobic bacteria. It is important to follow proper packaging and labeling guidelines to ensure the integrity of the specimen during transport.
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
What types of organisms are subjected to Negative Staining Technique?
Bacteria .
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 technique is used to make bacteria that produce drugs?
recombinant technology
How is pollution fought with bacteria?
Bacteria have been developed that can metabolize (eat) many pollutants.
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?
The Gram stain is a laboratory technique used to differentiate bacteria into two groups based on their cell wall composition: Gram-positive bacteria retain the violet stain, while Gram-negative bacteria appear pink/red after a counterstain with safranin. This staining method is named after the Danish bacteriologist Hans Christian Gram, who developed it in 1884.
What characteristic does a gram stain indicate?
A Gram stain indicates the cell wall structure of bacteria, differentiating them into two broad categories: Gram-positive (purple) and Gram-negative (pink) based on the ability of their cell walls to retain a crystal violet-iodine complex. This staining technique is an important tool in microbiology for identifying and classifying bacteria.
