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 beta-lactamase activity, implying that the cephalosporins (ceftiofur) remained active. Resistance to trimethoprim, aminoglycosides and fluoroquinolone ranked next. In contrast to the S. gallolyticus and E. coli strains, the S. enterica strains were susceptible to all the antimicrobials tested.
对从信鸽（家鸽）中分离出的33株解脲链球菌、60株大肠杆菌和18株鼠伤寒沙门氏菌哥本哈根变种菌株，检测了它们对最常用于治疗鸽子的抗菌药物的敏感性。采用琼脂稀释技术测定最低抑菌浓度。氨基糖苷类（庆大霉素和卡那霉素）、甲氧苄啶和氟甲喹对所检测的链球菌相对无活性。获得性四环素耐药率达85%，林可霉素和大环内酯类（红霉素）耐药率分别为48%和45%。在4株解脲链球菌菌株中发现了氟喹诺酮（恩诺沙星）耐药性。所有菌株对氨苄西林敏感。对于大肠杆菌菌株，对所有检测的抗生素均发现有耐药性。其中超过一半对四环素和广谱青霉素（氨苄西林）耐药；然而，没有一株显示出超广谱β-内酰胺酶活性，这意味着头孢菌素（头孢噻呋）仍然有效。对甲氧苄啶、氨基糖苷类和氟喹诺酮的耐药性次之。与解脲链球菌和大肠杆菌菌株不同，肠炎沙门氏菌菌株对所有检测的抗菌药物均敏感。
