Thin paper discs containing an antibiotic have been placed on an agar plate growing bacteria. Bacteria are not able to grow around antibiotics to which they are sensitive. This is called "the zone of inhibition". Antibiotic sensitivity testing or antibiotic susceptibility testing is the measurement of the susceptibility of bacteria to antibiotics.

Tetracyclines are a group of broad-spectrum antibiotic compounds that have a common basic structure and are either isolated directly from several species of Streptomyces bacteria or produced semi-synthetically from those isolated compounds. [ 1] Tetracycline molecules comprise a linear fused tetracyclic nucleus (rings designated A, B, C and D ...
A broad- spectrum antibiotic is an antibiotic that acts on the two major bacterial groups, Gram-positive and Gram-negative, [ 1] or any antibiotic that acts against a wide range of disease-causing bacteria. [ 2] These medications are used when a bacterial infection is suspected but the group of bacteria is unknown (also called empiric therapy ...
