How might normal microbiota play a role in the development of antibiotic resistance in pathogenic bacteria

Expert Solution

Question

The normal microbiota plays an important role in the nutrients metabolism, providing immunity and xenobiotics, drugs metabolism. But sometimes, these microbioata play a role in the antibiotic resistance in bacteria pathogen that live inside host.

The normal microbiota have some resistance genes in them. But when human take high dose of antibiotics, long exposure of antibiotics, this lead to the mutation in them. The result of the mutation result in the development of the resistance in these bacteria. Further, these bacteria transfer their resistance genes to another microbioata and pathogenic bacteria by horizontal gene transfer methods like transformation, conjugation etc. This lead to the development of antibiotic resistance in pathogenic bacteria.

Antibiotic resistance in bacteria occurs because ___. Group of answer choices antibiotic exposure triggers mutations in bacteria human cells become immune to the effects of the antibiotics over time bacteria mutate in order to become resistant antibiotic use kills bacteria which are not resistant, leaving resistant bacteria to reproduce

I am interested in antibiotic resistance. How might I identify all genes that contribute to resistance to a given antibiotic in a particular isolate of bacteria all at once, using an approach that involves illumina sequencing? (note – this is not simply by genome sequence analysis – it’ll take a more complex experiment coupled to sequencing).

Which of the following did NOT contribute to an increase in antibiotic resistance in bacteria? Question 24 options: A) Prescribing of antibiotics for viral infections B) Addition of antibiotic to common household products, such as hand soap C) Failure by hospitals to sterilize surgical tools D) All of the above contributed to antibiotic resistance in bacteria.

Describe how antibacterial soaps are among several factors that contribute to the rise of antibiotic-resistance bacteria.

1. Based on this lab, describe how antibiotic resistance in bacteria may have evolved including the mutation that created the gene, how antibiotics can cause natural selection, how the genetics of the bacteria changes over time (resistant and non-resistant), and how the genetics and phenotypes of the host (resistant and non-resistant) changes over time. 2. If flower color in a plant population is due to 2 alleles (R = red and r= white) which show incomplete dominance (Rr = pink),...
