据报道，沙门氏菌病是包括挪威和苏格兰在内的几个国家花园鸟类死亡的重要原因。我们调查了1993年至2003年（含）期间英格兰和威尔士公众提交尸检的花园鸟类的疾病频率。我们发现沙门氏菌病是最常见的死亡原因，由于传染病的花园鸟类提交。这种疾病在45种鸟类中的7种中得到证实，其中绿雀（Carduelis chloris）和家雀（Passer acutiticus）最常见。鼠伤寒沙门氏菌定型噬菌体型（DT）40、DT 56变体（v）和DT 160占分离株的大多数。沙门氏菌病事件主要发生在英格兰中部、英格兰/威尔士边境地区和英格兰南部。在研究期间发生的噬菌体类型的时空分布的变化。虽然全年都对鸟类进行了检查，但沙门氏菌病具有明显的冬季季节性。在受影响的绿雀中观察到一个显着的性别偏见，男性比女性更经常被诊断为沙门氏菌病。未观察到其他受影响种属的性别偏倚。需要进一步研究，以确定沙门氏菌病是否是受影响物种种群的一个重要限制因素，以及疾病爆发是否由人为因素（如供应）驱动。
Salmonellosis has been reported as an important cause of mortality of garden birds in several countries, including Norway and Scotland. We investigated the frequency of the disease in garden birds submitted for postmortem examination by members of the public in England and Wales between 1993 and 2003, inclusive. We found salmonellosis to be the most frequent cause of death due to infectious disease in the garden birds submitted. This disease was confirmed in 7 of the 45 bird species that were examined postmortem, with the greenfinch (Carduelis chloris) and the house sparrow (Passer domesticus) most frequently affected. Salmonella Typhimurium definitive phage type (DT) 40, DT56 variant(v), and DT160 accounted for the majority of isolates. Salmonellosis incidents chiefly occurred in the English Midlands, the English/Welsh border region, and southern England. Variation in the temporal and spatial distribution of the phage types occurred over the study period. While birds were examined throughout the year, there was a marked winter seasonality in salmonellosis. A significant sex bias was observed in affected greenfinches, with males more frequently diagnosed with salmonellosis than females. No sex bias was observed for other affected species. Further research is required to determine if salmonellosis is an important constraint to the populations of affected species and if disease outbreaks are driven by human factors, such as provisioning.
