From April to June 2020, during a period of increased mortality of tits (Cyanistes caeruleus, Parus major, Periparus ater) in Germany, 84 tits were pathomorphologically and microbiologically investigated in governmental veterinary investigation offices in North Rhine-Westphalia using a broad diagnostic panel. Although Suttonella ornithocola was the most frequently detected bacterium (36/84), other pathogens, in particular Chlamydia psittaci (12/65), were also identified, sometimes as concurrent infection (3/36). In conclusion, S. ornithocola-infection seems to play an important role within the epidemic tit mortality in North Rhine-Westphalia, Germany in 2020. However, these cases may be combined with sporadic and/or endemic causes of mortality (e.g., other pathogens, trauma, or predation) for these species.

从2020年4月至2020年6月，在德国山雀（Cyanistes caeruleus，Parus major，Periparus ater）死亡率增加的时期内，北莱茵-威斯特法伦州政府兽医研究办公室使用广泛的诊断小组对84只山雀进行了病理形态学和微生物学研究。尽管食管沙门氏菌是最常检测到的细菌（36/84 ），但也鉴定出其他病原体，特别是鹦鹉热衣原体（12/65），有时是并发感染（3/36）。总之，S。ornithocola-感染似乎在2020年德国北莱茵-威斯特法伦州的流行性山雀死亡率中起着重要作用。但是，这些病例可能与零星和/或地方性的死亡原因（例如其他病原体，创伤或掠食性疾病）结合在一起对于这些物种。
