When using combination antibiotic therapy, it is important to administer drugs that work synergistically as possible. Which of the following represents a combination with known synergism? A beta-lactam and an aminoglycoside A penicillin and a cephalosporin Two drugs in which the second drug will displace the first from plasma protein-binding sites. Two drugs that are eliminated by different routes Two drugs that work on the same step in a metabolic pathway.

step 1 Staphylococcus aureus is a bacteria, that is now resistant to commonly used antibiotics, and it is now resistant to the antibiotic methicillin (narrow spectrum beta lactam class). step 2 Describe the physiological mechanism used by individual bacteria to resist the antibiotic listed in above of this Thought Question. For example, the mechanism could be modification of drug, modification of target, prevention of drug penetration, overproduction of target, or target mimicry. (This means that you must choose a strain of bacteria that we know the characteristic of the bacteria that allows the bacteria to be resistant.)

Name two classes of antibiotics with different pharmacophores on them and briefly describe their mechanism of action with particular emphasis on the chemical reactions that cause their medicinal effects

In 2015, the WHO surveyed 10,000 people on the subject of drug resistance. Seventy-five percent of them said that antibiotic resistance is due to the human body becoming resistant to the drug. Explain how you would correct this misconception?

Which of the following is a true statement about the aminoglycosides? Multiple Choice   They are a group of bacteriostatic antibiotics.   Their antibacterial spectrum mainly includes gram-positive bacilli.   They are active against anaerobic organisms.   They cause irreversible inhibition of bacterial protein synthesis.

Which definition goes with which 1) defensins 2) pentatraxins 3) bradykinin 4) psoriasis 5 ) alpha2 macroglobulin

This is from micro biology. Which box goes under which category

Is it as effective to take two antibiotics sequentially as it is to take them simultaneously, as long as the total length of time that they are both taken is the same? Explain.

Which of the following does NOT describe a mechanism for drug resistance? Prevention of drug entry into the cell Production of proteins that bind and sequester the drug Creation of new plasmids upon drug treatment Changes in the structure of the drug's target Inactivation of the drug by hydrolysis

Some antibiotics are effective against only a limited range of organisms. What is a term you learned in the virtual lab that is used to describe this phenomenon and describe what it means.
