Which of the following may indicate that you have correctly Subcultured an organism from a plate to a slant?

Which of the following may indicate that you have correctly subcultured an organism from a plate to a slant? After Gram staining a smear prepared from the slant, all of the cells have similar color and morphology under the microscope. The slant shows only one color of growth.

What is a colony microbiology quizlet?

colony. A colony is defined as a visible mass of microorganisms all originating from a single mother cell, therefore a colony constitutes a clone of bacteria all genetically alike.

What are the basic concepts of microbiology?

Microbiology is the study of all living organisms that are too small to be visible with the naked eye. This includes bacteria, archaea, viruses, fungi, prions, protozoa and algae, collectively known as ‘microbes’.

What is margin in microbiology?

3. Margin – The margin or edge of a colony (or any growth) may be an important characteristic in identifying an organism.

What is the purpose of the spread plate technique?

The spread plate method is a technique to plate a liquid sample containing bacteria so that the bacteria are easy to count and isolate. A successful spread plate will have a countable number of isolated bacterial colonies evenly distributed on the plate.

What is slant culture?

[ slănt ] n. A culture made on the slanting surface of a solidified medium in a test tube that has been tilted to provide a greater area for growth. slope culture.

What is a colony in microbiology?

In microbiology, a “colony” is a group of bacteria, fungi, and other microorganisms grown on a solid agar medium. The cells plated on this medium grow to form a mass, which can then be duplicated for further use in the lab.

What is the difference between colony and culture?

As nouns the difference between culture and colony is that culture is the arts, customs, and habits that characterize a particular society or nation while colony is a settlement of emigrants who move to a new place, but remain culturally tied to their original place.

What is the spreading of microbes called?

The spreading of microbes is called transmission. Transmission involves the following stages: Escape from the host or reservoir of infection (where the infectious agent normally lives and multiplies). Transport to the new host. Entry to the new host.

What is spread spread plating in microbiology?

Spread plating is routinely used in enrichment, selection, and screening experiments. Strick aerobes are favored while microaerophilic tends to glow slower. Crowding of the colonies makes the enumeration difficult. Mackie and McCartney. Practical Medical Microbiology

How do microorganisms spread from one food to another?

Microbes can be spread from one food to another during the preparation process, for example by unclean hands, or dirty kitchen utensils, and cause illness when those foods are eaten. This is known as cross-contamination.

How do diseases spread from one person to another?

Measles, mumps and tuberculosis can be spread by coughing or sneezing. A cough or a sneeze can release millions of microbes into the air in droplets of mucus or saliva which can then infect somebody else if they breathe in the infected particles. Microbes need nutrients for growth and they like to consume the same foods as humans.
