Amoxicillin therapy of poultry flocks: effect upon the selection of amoxicillin-resistant commensal Campylobacter spp. (2009)

Elviss, Nicola C., Williams, Lisa K., Jørgensen, Frieda, Chisholm, Stephanie A., Lawson, Andrew J., Swift, Craig, ...

Background The aim of this study was to investigate the effect of amoxicillin therapy of poultry flocks upon the persistence of commensal Campylobacter spp. and the incidence of antibiotic...

Selection of moxifloxacin-resistant Staphylococcus aureus compared with five other fluoroquinolones (2003)

Griggs, Deborah J., Marona, Herida, Piddock, Laura J. V.

Fluoroquinolone-resistant mutants were selected from Staphylococcus aureus NCTC 8532 (F77), and two GrlA mutants of F77 (F193 and F194) with moxifloxacin, sparfloxacin, ofloxacin, grepafloxacin,...
