Ciprofloxacin Hydrochloride is a high activity fluoroquinolone antibiotic effective against a broad spectrum of gram positive and negative bacteria such as Pseudomonas, Salmonella, streptococcus and Staphylococcus. Effective against mycoplasma (12 days).
Catalog #C5074
Ciprofloxacin differs from other quinolones in that it has a fluorine atom at the 6-position, a piperazine moiety at the 7-position, and a cyclopropyl ring at the 1-position.
The bactericidal action of ciprofloxacin results from interference with the enzyme DNA gyrase which is needed for the synthesis of bacterial DNA.
Ciprofloxacin has been shown to be active against most strains of the following organisms
Gram-Positive Bacteria Enterococcus faecalis (Many strains are only moderately susceptible); Staphylococcus haemolyticus; Staphylococcus hominis; Staphylococcus saprophyticus; Staphylococcus aureus; Staphylococcus epidermidis; Streptococcus pneumoniae; Streptococcus pyogenes.
