Why would a sputum sample have been collected before antibiotic therapy was commenced?

Is UV treament more or less effective than disinfection when used against Saphylococcus aureus?

how might you apply Kochs postulates to a pathogen that will not grow on culture media?

Suggest a possible mechanism for how a microbe that becomes resistant to an antimicrobial chemical can transfer that to another microorganism, and also transfer resistance to antibiotics in the process.

Discuss how the use of antimicrobial agents selects for resistant microbes and explain how resistance may spread by agricultural and clinical misuse. Summarize what healthcare workers and patients can do to reduce the emergence of antimicrobial resistance.

Which antimicrobial agents have the narrowest spectrum of action? antivirals antifungals beta-lactams sulfanilamidesBottom of Form Penicillin is a narrow spectrum antibiotic because it only affects bacteria with mycolic acid in its cell wall, such as Mycobacterium tuberculosis. it only affects viruses it only affects Gram-negative organisms it only affects Gram-positive organismsBottom of Form Which of the following antibiotics might be destroyed by beta-lactamase enzymes? amphotericin B and ciprofloxacin streptomycin penicillin ciprofloxacinBottom of Form Which is incorrect about how the pharmaceutical industry has discovered drugs over the past 100 years? The process of discovery has involved custom-designing chemical compounds that we know will bind to target enzymes. The process of discovery has involved screening for chemicals that are toxic to bacteria while being less toxic to human cells. The process of discovery has involved screening thousands of randomly…

Which of the following is not a factor that should be considered when selecting a antimicrobial drug? A.  The nature of the microbe causing the infection B. The overall medical condition of the patient C. The origin of the drug D. The degree of susceptibility of the microbe to that drug

Why is Muller Hinton Agar (MHA) ideal for antibiotic susceptibility testing

suggest ways employed by microbes of extreme environments that enable them cope with harsh environmental conditions

If an infectious agent is sensitive to several antimicrobial drugs, what other considerations might be used to determine the best treatment option?
