Step by step
Solved in 3 steps
- Question 20 Medical microbiology laboratories are using molecular methods more and more to facilitate pathogen identification. What are the advantages of molecular methods, compared to traditional cultures? Question 20 options: a) Molecular methods provide rapid, quantitative results even for pathogens that have mutated b) Molecular methods are associated with increased sensitivity and yield rapid results c) Molecular methods are associated with increased sensitivity, and yield rapid results related to susceptibility testing d) Molecular methods yield results that remain positive for a long period of time, and are resistant to contamination with commensal organismsQuestion 16 Within the context of infectious disease, which of the following specimens would be considered irretrievable? Question 16 options: a) Wound swab b) Blood sample for therapeutic drug monitoring c) Cerebrospinal fluid d) Urine sampleQuestions 14-16 are based on the following. In the 1940's, Avery, Macleod, and McCarty transformed nonencapsulated bacteria into encapsulated. forms by growing the nonencapsulated cells in a culture containing an extract made from dead encapsulated cells. The transformed cells produced colonies of encapsulated bacteria. Three different procedures and their results are outlined below. Procedure I: Extract made from dead encapsulated cells added to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow. Procedure II: Extract made from dead encapsulated cells treated with protein-degrading enzymes before adding extract to culture medium. Nonencapsulated bacteria added to culture medium. Results: Both nonencapsulated and encapsulated bacteria grow. Procedure III: Extract made from dead encapsulated cells treated with DNAse (an enzyme that selectively destroys DNA) before adding extract to culture medium.…

Restriction Fragment Length PolymorphismQuestion 1. Pretend you are performing an Indirect ELISA on patient to detect Streptococcus pyogenes. You did all the steps correctly, except you forgot to wash the tube before adding the substrate. How would this mistake affect your results ? Would you still be able to tell if the patient was positive or negative for S. Pyogenes?My professor instructed me to make presentation on this topic "Periodontal microbes interaction with FISH". I have to make 4 power point slides regarding this topic. Can you give some information about the topic which i can use in the slides? Also provide some necessary relevant diagram or image regarding the topic. Please answer at your own easy words. If you do so i will rate you positive, Thank you.
- i need help finding the answer in the article Why does it make sense to look for ARGs and not antibiotic-resistant organisms themselves?Question 1: A. In Northern blotting, electrophoresis is used to resolve which biological molecules? What type of probe is used to identify the target molecule(s)? B. In Southern blotting, electrophoresis is used to resolve which biological molecules? What type of probe is used to identify the target molecule(s)? C. In Western blotting, electrophoresis is used to resolve which biological molecules? What type of probe is used to identify the target molecule(s)? D. Which of these techniques gives information about the expression levels of genes?Question 15 How did you select and grow a streptomycin resistant strain of bacteria in this experiment? 1. A sample of bacteria was exposed to streptomycin by inoculating it onto a streptomycin negative plate. Colonies that grew carried a mutation for resistance 2. A colony of bacteria was with streptomycin so that the antibiotic could alter then genetic composition of the bacteria . 3. A sample of bacteria was exposed to streptomycin by inoculating it onto a streptomycin positive plate. Colonies that grew carried a mutation for resistance

Samples of bacteria were taken from the culture and observed under a microscope for signs of susceptibility or resistance . Those that were resistant were separated and plated .Question 20 Drugs that target viral gene expression must accomplish functional in human hosts. Block viral entry Reverse transcriptase Block viral genetic takeover All of the above in order to bequestion: Can you summarize and explain for me what you want to tell in the article below? Can you explain the figure? When I read it myself, I do not understand exactly what is meant by the article. It would be nice if you could highlight the important points. You can use them in a figure or diagram to explain. thank you and hava a nice day :) Article: Nanotechnology Tools to Detect SARS-CoV-2 Standard procedures for detecting the virus from nasopharyngeal and/or oropharyngeal swabs have been reviewed recently and are primarily based on reverse transcription polymerase chain reaction (RT-PCR). Here, we would like to mention some preliminary ideas on nanotechnology-based assays to monitor the presence of SARS-CoV-2. A simplified test and variants thereof to detect viral proteins (e.g., HIV or influenza virus) without the need for expensive equipment is based on the color change of Au NPs bound to antibodies. Similar to the enzyme-linked immunosorbent assay (ELISA) antibodies coupled…
