TL;DR: It was concluded that S. chromogenes can be identified reliably in routine mastitis bacteriology, and that the only resistance of importance is against penicillinase-susceptible penicillins.

TL;DR: Copenhagen strains isolated from homing pigeons were tested for susceptibility to the antimicrobials most commonly used to treat pigeons, and none showed extended spectrum β -lactamase activity, implying that the cephalosporins (ceftiofur) remained active.
Abstract: Thirty-three Streptococcus gallolyticus , 60 Escherichia coli and 18 Salmonella enterica serotype Typhimurium var. Copenhagen strains isolated from homing pigeons ( Columba livia ) were tested for susceptibility to the antimicrobials most commonly used to treat pigeons. Minimal inhibitory concentrations were determined using the agar dilution technique. Aminoglycosides (gentamicin and kanamycin), trimethoprim and flumequine were relatively inactive against the streptococci tested. Acquired tetracycline resistance amounted to 85%, and lincomycin and macrolide (erythromycin) resistance to 48 and 45%, respectively. Fluoroquinolone (enrofloxacin) resistance was found in four S. gallolyticus strains . All strains were susceptible to ampicillin. With the E. coli strains, resistance was found to all antibiotics tested. Over one-half of them were resistant to tetracycline and to broad-spectrum penicillins (ampicillin); however, none showed extended spectrum β -lactamase activity, implying that the cephalosporins ...
