Abstract:
The aim of this systematic review was to investigate the prevalence of leptospirosis among stray and sheltered dogs worldwide. Six databases were searched, which resulted in the retrieval of 476 articles. Sixty articles were selected for analysis according to 10 quality criteria. Among the selected papers, 26 papers [43.4% (26/60)] met five of the 10 quality criteria established, 10 papers [16.7% (10/60)] met three criteria, nine papers [15.0% (9/60)] met four criteria, six papers [10.0% (6/60)] met six criteria, four papers [6.7% (4/60)] met eight criteria, and three papers [5.0% (3/60)] met nine of the 10 criteria, whereas two papers [1.7% (1/60)] met two and seven [1.7% (1/60)] criteria. Publications originated mainly from the Americas [45.0% (27/60)] and in the last 16 years (2003-2019) [81.7% (49/60)], and most of the sampled dogs were stray dogs [65.0% (39/60)]. The most commonly used diagnostic test for leptospirosis was the microscopic agglutination test [78.4% (47/60)] followed by polymerase chain reaction [21.7% (13/60)], and the most common serovars were Canicola [71.4% (35/49)], Icterohaemorrhagiae [65.3% (32/49)], Grippotyphosa [40.8% (20/49)], and Pomona [40.8% (20/49)]. In conclusion, our results showed that Leptospira spp. are present in unowned dogs worldwide; however, the low-methodological quality of the recovered cross-sectional studies precluded a meta-analysis.
摘要:
这项系统评价的目的是调查全球流浪犬和庇护犬中钩端螺旋体病的患病率。搜索了六个数据库,共检索到476篇文章。根据10项质量标准选择60篇进行分析。在选定的论文中,26篇论文[43.4%(26/60)]符合制定的10项质量标准中的5项,10篇论文[16.7%(10/60)]符合三个标准,九篇论文[15.0%(9/60)]符合四个标准,六篇论文[10.0%(6/60)]符合六个标准,四篇论文[6.7%(4/60)]符合八项标准,三篇论文[5.0%(3/60)]符合10项标准中的9项,而两篇论文[1.7%(1/60)]符合两个和七个[1.7%(1/60)]标准。出版物主要来自美洲[45.0%(27/60)],过去16年(2003-2019年)[81.7%(49/60)],大多数采样犬是流浪狗[65.0%(39/60)]。钩端螺旋体病最常用的诊断试验是显微凝集试验[78.4%(47/60)],其次是聚合酶链反应[21.7%(13/60)],最常见的血清型是Canicola[71.4%(35/49)],肺出血[65.3%(32/49)],Gripotyphosa[40.8%(20/49)],和波莫纳[40.8%(20/49)]。总之,我们的结果表明钩端螺旋体。存在于世界各地的无主狗中;然而,回收的横断面研究的方法学质量较低,因此无法进行荟萃分析.
