Obtained a small Styrofoam cooler placed two small light bulbs in side and observed temperature over 24 hours to ensure temperature could be maintained between 98-100 degrees. Using a 10% bleach solution I then cleaned my work area. Transferring one capsule of L. acidopholis into a tube of MRS broth using...
A. What is the differencebetween a bactericidal and bacteriostaticagent? What is the differencebetweensterilization and disinfection?
Control of growth refers to the prevention of growth of microorganisms...
temperature requirements: one type is best grown at room temperature while the other requires a temperature similar to that of our physical body (between 35 and 37 degrees Celsius).
The second step is to select the appropriate medium for the specified microbe. In this experiment we will use a liquid...
1. What is the differencebetween a bactericide and something that is bacteriostatic?
Bactericidal- Drug that kills bacteria Bacteriosstatic- Drug that limits or slows the growth of bacteria
a. What is a germicide?
properly use aseptic techniques to transfer cultures, learning about cultured media and how to distinguish various types of microbial growths as well as what is required for them to grow properly.
This exercise will allow me to gain knowledge of how to properly use aseptic techniques,...
transform normal cells into cancerous cells. Viruses that are capable of producing tumors are called oncogenic viruses.
Discuss the relationship between DNA- and RNA-containing viruses and cancer.
Molecular biological research shows that the mechanisms of the diseases are similar, even when a virus...
disinfectants by disk diffusion method using common agents such as Betadine, Clorox, Crest, Kiss My Face, Listerine, and Lysol. Wound care and general cleaning of home surfaces is a part of daily activity for many of the general population. Knowing which agents are effective against the bacteria that most commonly...
biology is critical to bacteriologists and other forensic investigators attempting to identify potential biogenic pathogens that may be exploited as agents in biological warfare or by bioterrorists.
Fundamentals of Bacterial Biology
Bacteria are one-celled prokaryotic organisms that lack a true nucleus...

microorganisms on a skin or tissue.
Degerming – the removing of microbes from a surface by scrubbing.
Methods of controlling microbial growth
Sterilization, Disinfection, Antisepsis, Degerming, Pasteurization
Mechanisms of controlling microbial growth
Prevent Growth, Kill microbes (physical, chemical)
STERILIZATION AND DISINFECTION
BacteriostaticAgent: An agent that inhibits the growth of bacteria, but does not necessarily kill them. Bactericide:
An agent that kills bacteria. Most do not kill Endospores.
An agent that kills spores.

a) Phosphorylation - the addition of phosphate to a chemical compound
b) What are the 3 mechanisms of phosphorylation used by organisms?
• Substrate level phosphorylation – ATP is generated when a high-energy phosphate is directly transferred from a phosphorylated...

C) probably do not have a common ancestor
D) have never shared genes between domains
E) may be classified in three domains, probably do not have a common ancestor AND have never shared genes between domains
1. The two magnifying lenses found in a light microscope are...
Antimicrobial therapy takes advantage of the differences that exist between microorganisms and human beings. Antimicrobial or anti-infective agents can be classified as bactericidal (kills organisms) or bacteriostatic (prevents growth of organism). Both types are effective therapeutically...
Upon completion of this module you will be able to: • Explain why susceptibility testing is done • Define the terms, bacteriostatic and bactericidal • Describe the functional antibiotic classification scheme and list the 5 main groups • Name at least one antibiotic in each class • Describe...
