Consider 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
a.) which two of the following three species are more closely related: Entamoeba histolytica, Escherichia coli, Entamoeba coli? Explain.
b.) two organisms are in the same order but not in the same family. From this information, can you determine whether they are in the same class? Explain.
Bacillus cereus and Bacillus thuringiensis are very closely related species and cannot be distinguished clearly by biochemical tests and 16S rRNA sequencing. Designate TWO (2) ways that you may use to differentiate these two species.
