day 6 micro study guide

Selective toxicity

A drug that kills harmful microbes without damaging the host

Beta-lactams

Penicillins
Cephalosporins
Carbapenems
Monobactams

Bacitracin

antibiotic; inhibits cell wall synthesis

Vancomycin

antibiotic; a glycopeptide antimicrobial , is the most widely used agent for the treatment of serious infections caused by gram-positive pathogens.

Polymyxins

interact with phospholipids and cause leakage, particularly in gram-negative bacteria

Isoniazid

isoniazid is in a class of medications called antituberculosis agents. It works by killing the bacteria that cause tuberculosis

Beta-lactamase

Any of a group of enzymes produced by bacteria that catalyze the chemical opening of the crucial beta-lactam ring structures in beta-lactam antibiotics

Antimicrobial compounds combat

bacteria, fungi, helminths, protozoans, and viruses.

understanding structural and functional features of microbes allows us to

develop new antimicrobial drugs and assess drug specificity mechanisms to limit adverse drug effects.

The type of antimicrobial drug used to treat a particular pathogen depends on

patient and microbe features.
