- Lysine Decarboxylation:Q13) Give me the expected results for Enterobacter aerogenes and Proteus mirabilis.What is the mode of action for kanamycin? Is it bacteriostatic or bactericidal? https://pubchem.ncbi.nlm.nih.gov/compound/KanamycinConsider the photos here which demonstrate antibiotic sensitivities of Staphylococcus aureus strains as determined by the Kirby-Bauer method. Abbreviations are as follows: C = chloramphenicol; CC = clindamycin; CZ = cefazolin; E = erythromycin; NOR = norfloxacin; OX = oxacillin; P = penicillin; RA = rifampin; SAM = sulbactam-ampicillin; SXT = sulfatrimethoprim; TE = tetracycline; VA = vancomycin. Imagine that only two cellular changes occurred in the original strain (the first image, on the top) that resulted in the resistance pattern of the strain in the second image (on the bottom). Which combination of mechanisms could explainthese results?Choose one or more: A.expression of efflux pumps B.overproduction of PABA C.production of β-lactamase D.altered penicillin-binding protein E.modification of either 50S or 30S ribosomal subunits F.altered DNA gyrase
