Which best describes the crisis related to antibiotics.
. C The bacteria should try to make the cost worthwhile by locating and migrating to microenvironments where traces of antibiotics are present. The bacterias genetic material mutates in response to the antibiotic resulting in resistance. β-Lactam antibiotics are a broad class of antibiotics that includes penicillin derivatives penams cephalosporins cephems monobactams and carbapenems.
The addition of antibiotics to a bacterias environment causes mutations in the bacterias genes that make them resistant to death by the antibiotic chemical. It takes too much time to develop effective antibiotics. Antibiotic use is not a factor in antibiotic resistance.
Antibiotic resistance is a big problem in the United States but not the world. VISA isolates are infrequent so surveillance at the present time is not warranted. The bacteria develops resistance to the antibiotic in direct response to its application.

Bacteria are increasingly resistant to antibiotics used to treat and eradicate infections. Which best describes what happens when an antibiotic is applied to a population of bacteria. Penicillin is аn аntibiоtic thаt kills bacteria by binding tо the active site оf an enzyme involved in synthesis of the bacterial cell wall.
VISA isolates are usually methicillin susceptible. Please select the best answer. The lactate level should reduce by more than 80 of its initial value to indicate a response to treatment.
Antibiotic resistance occurs when the body builds up a resistance to antibiotics.

Which antibiotic use measure could be most useful to track in order to evaluate the impact of a new facility treatment guideline that specified 5 days of antibiotics should be used for treatment of bacterial pneumonia.
B These bacteria should be outcompeted and replaced by bacteria that have lost these genes. It is becoming too expensive to manufacture effective antibiotics. A These genes should continue to be maintained in case the antibiotics ever appear.
Which statement BEST describes antibiotic resistance. C Antibiotic-resistant microbes are selected for in humans who are taking antibiotics. Resistance to antibiotics is a trait that didnt exist before antibiotics were developed for pharmaceutical use.
When a type of bacteria is resistant to antibiotics its resistant to all antibiotics. Which of the following statements about antibiotics is incorrect.
