The provision of supplementary food for wild birds in gardens during the winter months is common in the UK, but it is possible that it may precipitate infectious diseases in the birds. This paper describes the results of postmortem examinations of 116 wild finches carried out over a period of four years. The two commonest causes of death in areas where high mortality had been reported were infections with the bacteria Salmonella typhimurium DT40 and Escherichia coli O86. Coccidia of the genera Atoxoplasma or Isospora were found in several of the birds but were considered to be incidental. Megabacteria were also identified in some of the birds, for the first time in flocks of wild birds in the UK, but they were not considered to be significant.
在英国，冬季在花园为野生鸟类提供补充食物的做法很常见，但这可能会促使鸟类感染传染病。本文描述了在四年时间里对116只野生雀类进行尸检的结果。在报告高死亡率的地区，最常见的两个死亡原因是感染鼠伤寒沙门氏菌DT40和大肠杆菌O86。在几只鸟中发现了阿托弓形虫属或等孢球虫属的球虫，但被认为是偶然现象。在一些鸟类中还首次发现了巨型细菌，这在英国的野生鸟类群体中尚属首次，但它们被认为并不重要。
