Pharmacological properties

АТСvet: QJ01. Antibacterials of systemic action. QJ01DE90. Cefquinome. 

Cefquinome is a cephalosporin of the 4th generation, which has a broad spectrum of antibacterial action against most gram-positive and gram-negative bacteria (Escherichia coli, Enterobacter spp., Staphylococcus aureus, Streptococcus spp., Clostridium spp., Actinobacillus spp., Citrobacter spp., Klebsiella spp., Pasteurella spp., Proteus spp., Salmonella spp., Serratia marcescens, Histophilus somni, Arcanobacterium pyogenes, Bacillus spp., Corynebacterium spp., Bacteroides spp., Fusobacterium spp., Prevotella spp. and Erysipelothrix rhusiopathiae), particularly, upon strains producing β-lactamase. Mechanism of bactericidal effect of cefquinome consists in inhibition of synthesis of cell membrane of microorganisms.

Enrofloxacin is a broad-spectrum antibiotic of the fluoroquinolone group. The drug is effective against gram-positive and gram-negative microorganisms (Staphylococcus spp., Streptococcus spp., Clostridium spp., Listeria monocytogenes, Corynebacterium spp., Pseudomonas spp., E. coli, Haemophilus spp., Salmonella spp., Klebsiella spp., Proteus spp., Pasteurella spp. etc.) as well as mycoplasma and chlamydia. The mechanism of action is related to inhibition of bacterial DNA-gyrase, which results in disturbance of replication of bacterials DNA.
