    Chloramphenicol

  • 11

    The ____ must have selective toxicity.

    antimicrobials

  • 12

    The antimicrobial agent must be in an __

    active form

  • 13

    these agents cause cell lysis, thus killing bacteria.

    Bactericidal

  • 14

    hese agents inhibit growth without killing them; they rely host’s immune system to follow through to destroy the pathogen.

    Bacteriostatic agents

  • 15

    antibiotics with limited spectrum or group of bacteria

    Narrow spectrum antibiotics

  • 16

    antibiotics with a wide range against gram-positive and gram-negative bacteria.

    Broad spectrum antibiotics

  • 17

    inhibits bacterial cell wall synthesis by binding to the end of PG, interfering with transpeptidation.

    Vancomycin

  • 18

    Binding to and disrupting the cell membrane of gram-positive bacteria. Effective against beta lactams resistant bacteria

    Lipopeptides

  • 19

    Irreversible binding to protein receptors on the organism’s 30S ribosomal subunit

    Aminoglycosides

  • 20

    inhibits the addition of amino acids to the growing peptide chain by reversibly binding to the 50S ribosomal subunit

    Chloramphenicol

  • 21

    Broad-spectrum bacteriostatic antibiotics. Activity against gram-negative bacteria, gram-positive bacteria, Mycoplasma spp., several intracellular bacterial pathogens, and some protozoa.

    Tetracyclines

  • 22

    semisynthetic antibiotics that bind to the enzyme DNA-dependent RNA polymerase and inhibit synthesis of RNA.

    Rifamycin

  • 23

    organism has inherent characteristics enabling it to be resistant to certain antimicrobials even before antibiotic use.

    intrinsic resistance

  • 24

    necessitated by prior exposure to the antimicrobial agent. Organisms that were once susceptible are now resistant.

    Acquired resistance

  • 25

    when the zone edge is outside the black circle

    Susceptible

  • 26

    when there is no zone, or when it lies within the white circle

    Resistant

  • 27

    bind bacterial ribosomal proteins and rRNA, disrupting synthesis of RNA, DNA, and proteins

    Nitrofurantoin

  • 28

    Similar activity with sulfonamides

    Trimethoporin
