A)biotyping.
B)antibiograms.
C)bacteriocin typing.
D)bacteriophage typing.

Question

Quizplus · Accepted Answer

Classic phenotypic techniques include biotyping (analyzing unique biologic or biochemical characteristics),antibiograms (analyzing antimicrobial susceptibility patterns),and serotyping (serologic typing of bacterial or viral antigens,such as bacterial cell wall [O] antigens).Bacteriophage typing,which examines the ability of bacteriophages (viruses capable of infecting and lysing bacterial cells),and bacteriocin typing,which examines an organism's susceptibility to bacterial peptides (proteins)to attack certain strains,have been useful for typing P.aeruginosa and S.aureus,respectively.These techniques,however,are not widely available.
