In a series of infection experiments, a researcher discovers that the ID50 value for the infectious bacterium Parasiticum mucoides is 2,000, and that the ID50 for another infectious bacterium, Donoteatum thisbacterium, is 150. Given these data, a person exposed to 1,000 bacteria of each type would be more likely to be infected by which bacterium?

The worldwide spread ofmultidrug-resistant (MDR) pathogenicbacteria has becomean urgent threat to human and animalhealth. More than two million people inthe United States become infected withantibiotic-resistant bacteria each year, andmore than 23,000 of them will die fromtheir infections. In 2015, approximately480,000 cases of MDR tuberculosisoccurred worldwide and another 100,000cases were resistant to at least one antibiotic.In the United States, cases of drugresistantenterobacteriaceae infectionsincreased three-fold between 2001 and2012. In 2016, a woman in Nevada died ofa Klebsiella pneumoniae infection caused bya strain that was resistant to 26 differentantibiotics, including colistin, which is consideredthe “last resort” antibiotic.One factor leading to the spread ofMDR bacteria is the selective pressurebrought about by repeated exposure toantibiotics.

Chapter 9 L discusses some oxygen requirement, grouped. We're going to focus on those that do not necessarily need oxygen for survival. For this part: aerotolerance, categories under which most prokaryotic organisms can be 1. What oxygen requirement, or aerotolerance, categories allow for an organism to survive in the complete absence of oxygen? Please list those oxygen requirement/aerotolerance categories where an organism doesn't necessarily need oxygen for growth. 2. Oxygen is toxic to most organisms, even you! One reason we don't see the effects of this is because most organisms are able to produce enzymes to counteract this toxicity. This is called, "detoxifying reactive oxygen species (ROS)," as discussed in Chapter 9. In order to survive in the presence of oxygen (if it can), a prokaryotic organism must be able to undergo detoxification of reactive oxygen species. For each category you listed in 1), please provide: A. the enzymes that may be lacking/missing in order to detoxify…
