Abstract

Aims: To investigate the frequency of carriage of methicillin-susceptible and methicillin-resistant Staphylococcus pseudintermedius (MRSP) in a population of clinically normal dogs within the Christchurch and wider Canterbury region, an area in which MRSP has been detected.

Methods: Buccal and perianal swabs were collected from 126 clinically normal dogs presenting at veterinary clinics in the Christchurch/Canterbury region for de-sexing or routine vaccination. S. pseudintermedius was isolated by selective culture. Isolates were tested for susceptibility to 12 antimicrobials by disc diffusion.

Results: S. pseudintermedius was isolated from 92/126 (73.0 (95% CI = 64.4-80.5)%) dogs, with 38/126 (30.2 (95% CI = 22.3-39.0)%) positive dogs carrying S. pseudintermedius at both sampled sites. More animals (78/126; 61.9 (95% CI = 52.8-70.4)%) had positive mouth cultures than positive perianal region cultures (52/126; 41.3 (95% CI = 32.6-50.4)%). No MRSP was isolated from clinically normal dogs. However, resistance to penicillin (106/130 (85.1%) swabs) and tetracycline (33/130 (25.4%) swabs) was seen.

Conclusions: The majority of the dogs in this sample were carriers of S. pseudintermedius. However, none of these isolates were MRSP.

Clinical relevance: While most clinically normal dogs in the studied region are likely to be carriers of S. pseudintermedius, only a small proportion, if any, are likely to be carriers of MRSP. Antibiotic stewardship practices may be important to maintain low-level circulation of drug-resistant bacterial lineages.

新西兰坎特伯雷临床正常犬携带假中葡萄球菌。

目的:调查在基督城和坎特伯雷地区临床正常犬群中甲氧西林敏感和耐甲氧西林假中葡萄球菌(MRSP)的携带频率，该地区已检测到MRSP。方法:收集在基督城/坎特伯雷地区兽医诊所就诊的126只临床正常犬的口腔和肛周拭子，进行绝育或常规疫苗接种。采用选择性培养分离出假中间球菌。采用圆盘扩散法检测分离株对12种抗菌药物的敏感性。结果:在92/126 (73.0 (95% CI = 64.4 ~ 80.5)%)只犬中分离到假中间链球菌，在两个采样点均有38/126 (30.2 (95% CI = 22.3 ~ 39.0)%)只阳性犬携带假中间链球菌。更多的动物(78/126;61.9 (95% CI = 52.8-70.4)%)口腔培养阳性患者多于肛周培养阳性患者(52/126;41.3 (95% ci = 32.6-50.4)%)。临床正常犬未分离到MRSP。但对青霉素(106/130(85.1%)拭子)和四环素(33/130(25.4%)拭子)耐药。结论:该样本中大多数犬为假中间链球菌携带者。然而，这些分离株都不是MRSP。临床相关性:虽然研究地区大多数临床正常的狗可能是假中间链球菌的携带者，但只有一小部分(如果有的话)可能是MRSP的携带者。抗生素管理实践对于维持耐药细菌谱系的低水平循环可能很重要。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
