- The reason why most antibiotics as oral suspension dosage forms are commercially available as dry powders, to be reconstituted with water just prior to dispensing, is:Why is it recommended to add pre- and probiotics to antibiotic treatment?Changes in the bacterial genome can lead to resistance to antimicrobialdrugs. what the different ways that these changes in the DNA occur?
- The disc diffusion assay measuring a disinfectant's effectiveness against a microorganism is more standardized than measuring an antibiotic's effectiveness with the kirby-Bauer assay. a) True b) FalseWhat is the main group of microorganisms producing the most antibiotics? Describe the biochemical characteristics of this microorganism and provide TWO (2) examples of antibiotics produced by these microbes.According to USP Chapter <797>, allergenic extract preparation can be made in a doctor’s office facility by trained personnel only if the allergenic extract preparation: a)Is compounded under a laminar air flow hood Is compounded by a pharmacist b)Contains an antimicrobial preservative c)Is used immediately after preparation d)Is prepared only from plant origin material
- What is the mode of action for kanamycin? Is it bacteriostatic or bactericidal? https://pubchem.ncbi.nlm.nih.gov/compound/KanamycinWhat are some of the disadvantages of using natural penicillin for treatment of infections?After a series of experiments, bacterial cultures were identified for disposal. How can these be properly decontaminated prior to disposal according to biosafety guidelines? METHOD:RATIONALE:
- A suspected pathogen is observed from the blood of a diseased mouse. An investigation of the other mice in the area indicates that it is not present in healthy mice. With Koch's postulates in mind, what is the next step to determine whether or not this suspected pathogen is the cause of disease in the mouse? a) Grow the suspected pathogen in a pure culture Ob) Re-isolate the suspected pathogen and show that it is the same as the original pathogen c) Inoculate a healthy mouse with the suspected pathogen O d) Determine whether the organism in the pure culture is the same one as in the original sample5) Aseptic technique refers to A) the microbial inoculum placed into a test tube or onto a Petri plate. B) a series of practices to avoid contamination. C) the autoclave and other sterilizing procedures. D) cleanliness in the laboratory.Below, you can see a picture of an antimicrobial drug.
