Salmonellosis was diagnosed in garden birds from 198 incidents in Scotland between September 1995 and August 2008. Salmonellosis was essentially a disease of finches in the north of Scotland, but in the south of Scotland it was also a problem in house sparrows. Almost all of the incidents were caused by Salmonella Typhimurium phage types 40 or 56/variant, but regional variation in phage types was observed. In the north of Scotland, one phage type (DT 40) predominated, but in the south of Scotland two phage types were commonly isolated (DTs 40 and 56/variant, with the latter the more common of the two phage types). This regional difference was statistically significant for salmonellosis in greenfinches, chaffinches and 'other garden birds', but not for house sparrows. Different temporal patterns for different species of bird and different phage types were also observed within regions. These findings suggest that the epidemiology of salmonellosis in garden birds varies depending on the phage type of Salmonella and the species of garden bird, with additional regional differences depending on the wild bird populations and the phage types of Salmonella in circulation. An awareness of these differences will help when formulating guidelines aimed at reducing the impact of salmonellosis in garden birds.
1995 年 9 月至 2008 年 8 月期间，在苏格兰的 198 起事件中诊断出了园林鸟类的沙门氏菌病。沙门氏菌病基本上是苏格兰北部雀形目鸟类的疾病，但在苏格兰南部，它也是家麻雀的一个问题。几乎所有的事件都是由肠炎沙门氏菌噬菌体 40 或 56/变体引起的，但观察到噬菌体类型存在地区差异。在苏格兰北部，一种噬菌体类型（DT40）占主导地位，但在苏格兰南部，两种噬菌体类型经常被分离（DTs40 和 56/变体，其中后者是两种噬菌体类型中更常见的一种）。对于绿翅雀、金翅雀和“其他园林鸟类”的沙门氏菌病，这种区域差异具有统计学意义，但对于家麻雀则没有。在不同地区，不同鸟类物种和不同噬菌体类型的沙门氏菌病也观察到不同的时间模式。这些发现表明，园林鸟类沙门氏菌病的流行病学因沙门氏菌的噬菌体类型和园林鸟类的物种而异，此外还因野生鸟类种群和流行的沙门氏菌的噬菌体类型而存在地区差异。了解这些差异将有助于制定旨在减少园林鸟类沙门氏菌病影响的指南。
