Description

Cefquinome is a 4th generation cephalosporin which is active against a broad spectrum of Gram positive and Gram negative bacteria. As many cephalosporin it acts by binding to bacterial PBP and thus inhibiting the cell wall synthesis. Cefquinome is approved for veterinary use in cattles with respiratory tract infections, skin infections, bacterial mastitis and septicaemia.

Sample Use Guides

In Vivo Use Guide

1 mg cefquinome/kg (2ml/50 kg body wt.) or 2 mg cefquinome/kg (4ml/50 kg body wt.) given by intramuscular injection (2,5% Cobactan solution).

Route of Administration: Intramuscular

In Vitro Use Guide

The MICs of cefquinome against single laboratory strains of gram-positive and gram-negative anaerobic bacteria were determined. The values were (MIC50): 0.781 ug/ml for Staphylococcus aureus (Methicillin susceptible); 12.5 ug/ml for Staphylococcus aureus (Methicillin resistant); <0.006 ug/ml for Streptococcus spp.; 4.0 ug/ml for Enterococci; 0.049 ug/ml for E.Coli and Klebsiella spp.; 0.098 ug/ml for Salmonella spp., Enterobacter spp. and Proteus mirabilis; 0.195 ug/ml for Serratia marcescens and Proteus spp.; 0.002 ug/ml for Streptococcus pyogenes; 0.008 ug/ml for Streptococcus pneumoniae and Klebsiella pneumoniae; 0.078 ug/ml for Pasteurella multocida, Proteus mirabilis ATCC 14273; 0.03 ug/ml for Escherichia coli 078 and 0.06 ug/ml for Salmonella typhimurium MZ II.
