S. aureus Strain
Figure 1. Macaque hemoglobin binding ability of different strains of S aureus
Which of the following experiments would be most appropriate to determine whether populations of S. aureus are continuously adapting in order to odtain iron from hosts more effectively
Grow S. aureus in media with macaque hemoglobin and abundant free iron. Record bacterial growth over time and compare it to growth of the original population
B Culture S. aureus bacteria with hernoglobin from a mixture of host species. Then transfer the bacteria to media with a known effective arnbiotic and record bacterial growth
c Sequence the genes of different s aureus strains and construct a cladogram representing their relatedness.
Culture S. aureus bacteria with hemoglobin from a novel host species as the only source of iron for many generations, then compare protein structure from bacteria in the culture with bacters from the
original culture.
