Antibiotic resistant mutant is more fit or less fit in comparison with parent type (original species)?
-
What would happen to the antibiotic resistant mutant if we remove this antibiotic from environment?
Homework Answers
1. The cost of ' fitness 'of an organism is its ability to replicate and survive in a competitive environment.
2. Antibiotic resistant mutant is less fit than in comparison with the parent type (original species).
3.Antibiotic concentrations are the main driving force in the environment for the selection of resistant bacterial populations.Bacteria become resistant when they encounter antibiotics in their environment in doses too small to kill them.If we remove antibiotic from the environment then drug resistance frequently declines within 480 generations during exposure .The extent of resistance loss was found to be generally antibiotic-specific. driven by mutation that reduce both resistance level and fitness costs of antibiotic resistance mutation.

2. Researchers in Israel have developed a novel method of restoring antibiotic sensitivity to resistant bacteria, according to a study in the journal Applied and Environmental Microbiology. The process could eventually be used to fight hospital superbugs, researcher said. An estimated 70% of hospital acquired infections in the U.S. involve bacteria that are resistant to at least one antibiotic. Using a process called lysogenization, scientists used bacteriophages, viruses that can infect bacteria, to invade resistant bacterial cells and restore their...

Procedure Four different colors of beads, representing four species of bacteria, all possible residents of the microbiome, will be utilized. The species differ naturally in their resistance to a particular antibiotic. Three different antibiotic treatment regimens will be modeled: following doctor’s orders ending antibiotic treatment early skipping Day 3 of treatment Your initial population of bacteria is represented as follows: 40 beads that represent Species 1, the most susceptible to the antibiotic (susceptible on Day 1 of treatment) 30 beads...

3. 25 points] The life of everyone in the world is currently affected more or less by the COVID-19 pandemic. A similar recent disaster was the 2002-2004 SARS. SARS is another type of coronavirus that spread quickly through respiratory droplets. We suspect SARS is more deadlier than COVID-19 and would like to compare the mortality rate of the two. Let pi and p2 be the respective mortality rate of SARS and COVID-19. We test H. : P1 = P2 versus...

Title: Development of an Adhesion Assay and Characterization of an Adhesion-Deficient Mutant of Pseudomonas fluorescens RESULTS Bacterial adhesion to sand columns. In the initial column assays with soil-and-sand mixtures, P. fluorescens PfO-1 and E. coli SLH25 had the highest and lowest adhesion values, respectively. Therefore, the sand column assay was optimized to yield the greatest difference in percent adhesion for these two strains. PfO-1 bacteria grown in minimal medium to the logarithmic phase were washed and suspended in either minimal...
