A psittacosis epidemic linked to fulmar hunting occurred on the Faroe Islands in the 1930s. This study investigates a plausible explanation to the 20% human mortality in this outbreak. Phylogenetic analysis showed that Chlamydia psittaci isolated from fulmars were closely related to the highly virulent 6BC strains from psittacines and are compatible with an acquisition by fulmars of an ancestor of the 6BC clade in the 1930s. This supports the hypothesis that the outbreak on the Faroe Islands started after naïve fulmars acquired C. psittaci from infected dead parrots thrown overboard when shipped to Europe in the 1930s.
上世纪 30 年代，法罗群岛爆发了一起与捕猎管鼻藿联系在一起的鹦鹉热疫情。本研究旨在对该次疫情中 20%的人类死亡率提供一种合理的解释。系统进化分析表明，从管鼻藿中分离出的鹦鹉热衣原体与来自鹦鹉的高毒力 6BC 株密切相关，这与 20 世纪 30 年代管鼻藿获得 6BC 分支的祖先一致。这支持了这样一种假说，即在 20 世纪 30 年代，当这些管鼻藿被运往欧洲时，被抛弃在海上的感染死亡的鹦鹉身上的衣原体感染了毫无经验的管鼻藿，随后法罗群岛爆发了疫情。
