Abstract

Predisposing factors for different types of urinary tract infections (UTI) were evaluated and prevalence of causative agents and their resistance were identified. A prospective epidemiologic study (2007 to 2012) included 191 dogs with signs of urinary tract disease. Anamnestic data were collected and clinical examination, abdominal ultrasonography, urinalysis and aerobic bacteriologic urine culture were performed in all dogs. Other diagnostic procedures were conducted when indicated. UTI was more common in neutered female dogs, older dogs and dogs with concurrent diseases. Using culture as the gold standard, sensitivity of urine sediment examination to detect bacteriuria increased from 89.9% to 98.1% with staining and specificity increased from 69.8% to 96.4%. A single species of microorganism was isolated in 90.7%. Most common causative agents of UTI were E. coli (39.0% of isolates), staphylococci (27.3% of isolates), Proteus sp. (13.5% of isolates), and enterococci (8.5% of isolates). Prevalence of the causative agents varied in regard to sex and concurrent diseases. The causative agents were in 29.4% susceptible to all tested antimicrobials and were multi-drug resistant in 27.7%. All methicillin resistant Staphylococcus pseudintermedius (MRSP) strains were isolated in 2010-2012. Resistant bacteria were more common in dogs previously treated with antimicrobials. Due to increased specificity and sensitivity of urine sediment examination, staining the sediment in practice is mandatory. Data on uropathogens and their resistance in regard to concurrent diseases is of crucial importance for diagnosis, treatment and prevention of complications in dogs with UT. Wide intercountry variability in bacterial susceptibility has been confirmed. Also, the onset of MRSP urinary strains in the country has been identified.

犬尿路病原体在并发疾病中的患病率和耐药模式。
评估不同类型尿路感染(UTI)的易感因素,确定病原体的流行情况及其耐药性。一项前瞻性流行病学研究(2007年至2012年)包括191只有尿路疾病迹象的狗。收集所有犬的记忆资料,进行临床检查、腹部超声检查、尿液分析和需氧细菌学尿液培养。其他诊断程序进行时,指征。UTI在绝育母犬、老年犬和并发疾病犬中更为常见。以培养为金标准,尿沉渣检查检测细菌尿的灵敏度由染色法的89.9%提高到98.1%,特异性由69.8%提高到96.4%。90.7%的细菌中分离出一种微生物。最常见的UTI病原体是大肠杆菌(39.0%)、葡萄球菌(27.3%)、变形杆菌(13.5%)和肠球菌(8.5%)。致病因子的患病率因性别和并发疾病而异。29.4%的病原菌对所有抗菌药物敏感,27.7%的病原菌对多种药物耐药。所有耐甲氧西林假中间葡萄球菌(MRSP)菌株均于2010-2012年分离得到。耐药细菌在以前接受过抗菌素治疗的狗身上更为常见。由于尿液沉积物检查的特异性和敏感性增加,在实践中对沉积物进行染色是强制性的。尿路病原体及其对并发疾病的耐药性数据对犬UT并发症的诊断、治疗和预防至关重要。已证实,细菌的易感性在国家间存在广泛的差异。此外,已经确定了该国MRSP尿株的发病情况。

期刊介绍: The Berliner und Münchener Tierärztliche Wochenschrift is an open access, peer-reviewed journal that publishes contributions on all aspects of veterinary public health and its related subjects, such as epidemiology, bacteriology, virology, pathology, immunology, parasitology, and mycology. The journal publishes original research papers, review articles, case studies and short communications on farm animals, companion animals, equines, wild animals and laboratory animals. In addition, the editors regularly commission special issues on topics of major importance. The journal’s articles are published either in German or English and always include an abstract in the other language.
