Which antibiotics were effective against E. coli?
Sri K.
Rank the antibiotics in order of effectiveness against E. coli. (Most effective is 1) (2 marks) Table 9.8: Most effective antibiotics against E. coli Antibiotic | Actual Ranking | Predicted Ranking | Broad / Narrow Spectrum Antibiotics Levofloxacin | 1 | 1 | Broad Tobramycin | 2 | 2 | Broad Streptomycin | 4 | 2 | Narrow Ampicillin | 3 | 3 | Broad Erythromycin | 5 | 3 | Broad 5. Did you correctly predict which antibiotic would be most effective and least effective against E.coli? Comment on factors affecting the correct or incorrect prediction. (2 mark)
Considering the mechanism of action of Beta-lactam antibiotics as an example, what would be your prediction? a. Gram negative bacteria will be more susceptible than Gram positive bacteria to Beta-lactam antibiotics b. Gram positive bacteria will be more susceptible than Gram negative bacteria to Beta-lactam antibiotics c. Gram negative bacteria will be as susceptible as Gram positive bacteria to Beta-lactam antibiotics d. Beta-lactam antibiotics are only effective against viruses
