The antimicrobial spectrum of an antibiotic can be determined by testing its antimicrobial activity against a wide range of microbes in vitro. Nonetheless, the range of microorganisms which an antibiotic can kill or inhibit in vivo may not always be the same as the antimicrobial spectrum based on data collected in vitro. [2] [5]
Antimicrobial spectrum is similar to that of metronidazole and is more well tolerated; [1]: 1368 however there are concerns of lower relative efficacy. [ 3 ] It was first introduced for treating trichomoniasis before being recognized for its broad anti-protozoan and anti-anaerobic-bacterial capacities.
The Spectral Database for Organic Compounds (SDBS) is a free online searchable database hosted by the National Institute of Advanced Industrial Science and Technology (AIST) in Japan, that contains spectral data for ca 34,000 organic molecules. [1]

Narrow-spectrum antibiotic allow to kill or inhibit only those bacteria species that are unwanted (i.e. causing disease). As such, it leaves most of the beneficial bacteria unaffected, hence minimizing the collateral damage on the microbiota. [2] [3] Low propensity for bacterial resistance development. [4]
These peptides have some antimicrobial properties; they inhibit the growth of Enterococcus spp. and a few other Gram-positive bacteria. These peptides act as pore-forming toxins that create cell membrane channels through a barrel-stave mechanism and thus produce an ionic imbalance in the cell [ 8 ]
Skeletal formula of tetracycline with atoms and four rings numbered and labeled.. 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]
The extended-spectrum penicillins are a group of antibiotics that have the widest antibacterial spectrum of all penicillins. [1] Some sources identify them with antipseudomonal penicillins , [ 2 ] others consider these types to be distinct. [ 3 ]
