Homework Answers
S.aureus can cause a range of illness from minor skin infections such as pimples,impetigo,boils,cellulitis,folliculitis,carbuncles,scalded skin syndromes and abscesses to life-threatening diseases such as pneumonia,meningitis,osteomyelitis,endocarditis,toxic shock syndrome,bacteremia and sepsis.Antibiotics are the drugs used to treat infections caused by bacteria.Sometimes bacteria can change so that these drugs are no longer effective.Over time, staph bacteria have become difficult to treat with certain antibiotics including Vancomycin.If there is some resistance it is called Vancomycin Intermediate S.aureus (VISA).If there is a lot of resistance it is called Vancomycin Resistant S.aureus (VRSA).VISA is extremely rare.Peoples with diabetics,kidney disease,previous infection with MRSA,recent hospitalisation are at higher risk for developing VISA infection.It can cause a range of symptoms including skin infection,abscesses,pneumonia and infections of heart valve,blood and bone.

Why is it frequently more difficult to treat fungal infections in humans than it is to treat bacterial infections? Select one: a. The cells found in fungi and humans are more similar than cells of bacteria and humans. b. Fungi undergo evolution at a much faster rate than bacteria do. c. Fungi normally grow in and on humans, and treating fungal infections would cause death of the human. d. Humans have not developed medications capable of targeting fungi.

Staphylococcus aureus can only cause disease when the cells reach a certain population size. Explain how S. aureus senses its cell density and activates gene expression. Based on this knowledge, discuss how antibacterial drugs can be designed to disrupt virulence and why these drugs have potential advantages over antibiotics to treat S. aureus infection.

A single Staphylococcus aureus bacteria cell gets into a wound on your foot. S. aureus divides by binary fission approximately once every 30 minutes (doubling time). Mutations occur at a rate of 1 per 1010 base pairs per generation. S. aureus has 2.8 x 106 base pairs in its genome. Therefore, approximately 0.0028 mutations will occur per bacterium in the population. As a Gram-positive bacteria, will this infection be susceptible to antibiotics? Explain your answer (reference one of the three...
