An epidemic caused by a successful host jump of the bacterial pathogen from poultry to house finches in the 1990s has by now spread across most of North America. causes severe conjunctivitis in house finches. We experimentally show that transmission to birds with or without chronic infection does not differ. However, once infected with house finches chronically infected with develop more severe clinical disease than birds without such infection. We speculate as to possible effects of coinfection.

20世纪90年代，一种细菌性病原体成功地从家禽传播到家雀，引发了一场疫情，目前这场疫情已蔓延至北美大部分地区。它在家雀中会引发严重的结膜炎。我们通过实验表明，向有或没有慢性感染的鸟类传播的情况并无差异。然而，一旦感染，与没有这种感染的鸟类相比，长期感染的家雀会出现更严重的临床疾病。我们推测了合并感染可能产生的影响。
