在这项研究中，我们检测了2011-2012年间从日本狗和猫身上分离的肠球菌的药敏情况。粪便样本来自84只接受抗生素治疗的狗和16只猫。84只狗中检出70只(83.3%)，16只猫中检出7只(43.8%)。粪肠球菌占64.9%，粪肠球菌占18.2%，杜氏肠球菌占6.5%，粪肠球菌占64.9%。对红霉素和土霉素的耐药率最高(44.2%)，对林可霉素(41.6%)、庆大霉素(31.2%)和卡那霉素(31.2%)也有相当大的耐药率。与2006年和2007年进行的一项类似研究的结果相比，肠球菌对恩诺沙星和氨苄西林的敏感性显著增加。从77株肠球菌中分离到4株携带vanC1的鸡肠球菌和携带vanC2/3的酪黄色肠球菌。但无一株肠球菌对万古霉素耐药。多药耐药性被发现，无论是哪种类型的抗菌药，少则两种，多则九种。这些结果表明，用抗生素治疗的狗和猫通常带有抗菌素耐药肠球菌。
In this study, we examined the antimicrobial susceptibility of the enterococci isolated from dogs and cats in Japan during 2011-2012. Fecal samples were collected from 84 dogs and 16 cats that underwent antibiotic treatment. Enterococci were detected in 70 of 84 dogs (83.3%) and 7 of 16 cats (43.8%). The most prevalent Enterococcus species was Enterococcus faecalis (64.9%); Enterococcus faecium and Enterococcus durans were also isolated from 14 of 77 (18.2%) and 5 of 77 (6.5%) of these animals, respectively. The most active resistance was observed for erythromycin (44.2%) and oxytetracycline (44.2%), and there was considerable resistance to lincomycin (41.6%), gentamicin (31.2%) and kanamycin (31.2%). Compared with the results of a similar study conducted in 2006 and 2007, enterococci susceptibility to enrofloxacin and ampicillin had significantly increased. Enterococcus gallinarum harboring vanC1 and Enterococcus casseliflavus harboring vanC2/3 were isolated from 4 of 77 enterococcal isolates. However, no enterococcal isolates were resistant to vancomycin. Multidrug resistance was found for as few as two and as many as nine antimicrobials regardless of the class. These results demonstrate that dogs and cats treated with antibiotics are commonly colonized with antimicrobial-resistant enterococci.
