1. The size of the zone of inhibition often varies for two different species of bacteria when challenged with the same antibiotic. What is a possible explanation for these differences? 2. Antibiotics can be bactericidal (they kill the microbe) or bacteriostatic (they inhibit microbial growth, but do not kill). When observing a zone of inhibition around a disk, how would you to determine whether the antibiotic causing that zone was bactericidal or bacteriostatic? 3. When performing antibiotic sensitivity testing, it...

Infants and small children have a substantially shorter ear canal. What effect would you expect this to have on their sensitivity to different frequencies? Select the correct answer The different length of ear canal should have no effect O on frequency perception because the speed of sound is the same regardless. The different length of ear canal should have no effect on frequency perception because only the resonant wavelength and not the frequency will change. Your Answet They should be...

what results would you get when testing these organisms (Klebsiella pneumoniae, Escherichia coli, Staphylococcus saprophyticus, Proteus mirabilis, Proteus vulgaris, Providencia stuarti, Pseudomonas aeruginosa, Enterobacter aerogenes, Morganella morganii) Tests being run: MacConkey agar test, a Gram staining test, SIM agar and Urea agar (just indicate if results are negative or positive)

Suppose that you have an environmental sample that when streaked out on agar, grows two different bacterial organisms with both cocci and bacilli which are not able to streak out for individual culture. From an ecological perspective, what kind of organisms might you have isolated? [1 mark] 2) Discuss the difference between the ecological concepts of symbiosis and mutualism. [2 marks] 3) If the organism that you were isolating in question 1 were pleomorphic, what would this mean? [2 marks]...
