Bjorn J A Berendsen et al.
Journal of chromatography. A, 1216(46), 8177-8186 (2009-05-02)
This paper describes our research on the degradation of ceftiofur and cephapirin at physiological temperatures in kidney extract and in alkaline and acidic solution, conditions that regularly occur during sample preparation. Degradation products were identified using LC-ToF/MS, NMR and microbiological

Environmental pollution (Barking, Essex : 1987), 157(6), 1849-1856 (2009-02-28)
Raman spectroscopy was used to investigate sorption mechanisms of cephapirin (CHP), a veterinary antibiotic, onto quartz (SiO(2)) and feldspar (KAlSi(3)O(8)) at different pH. Sorption occurs by electrostatic attraction, monodentate and bidentate complexation. The zwitterion (CHP(o)) adsorbs to a quartz((+)) surface

Veterinary microbiology, 134(1-2), 150-156 (2008-10-24)
Heifers (n=136) from 5 herds were treated with a commercially available beta-lactam intramammary (IMM) antibiotic preparation containing cephapirin sodium at 10-21 d prior to anticipated parturition to evaluate the risk of antibiotic residues occurring in milk postpartum and to determine
G Mari et al.
Theriogenology, 78(1), 189-200 (2012-04-03)
In cattle, elimination of bacterial contamination from the uterine lumen after parturition is often delayed or compromised, and pathogenic bacteria can persist, causing uterine disease and infertility. The aim of this study was to compare the clinical and bacteriologic recovery
A Lago et al.
Journal of dairy science, 94(9), 4441-4456 (2011-08-23)
The objective of this multi-state, multi-herd clinical trial was to evaluate the efficacy of using an on-farm culture system to guide strategic treatment decisions in cows with clinical mastitis. The study was conducted in 8 commercial dairy farms ranging in
