了解合并感染的发生和后果可能有助于设计疾病管理干预措施。两栖动物是最受威胁的脊椎动物，新出现的病原体对它们的保护构成严重威胁。两栖动物壶菌和蛙病毒属的病毒已经广泛分布，导致疾病爆发和世界范围内的人口下降。然而，我们缺乏信息的发生和后果的共同感染这些病原体跨年龄组的两栖类宿主。在这里，我们分析了发生在两个不同的地点，爆发了两个易感的两栖动物物种在一个季节的两栖动物壶菌和蛙病毒感染。我们发现，除了在高度易感的生命阶段，两种病原体在特定宿主中的共同发生并不常见，并且单一感染是最常见的情况。此外，我们发现一种病原体在特定宿主中的发生并不能预测另一种病原体的发生。我们将这些结果归因于这两种病原体在两栖动物宿主中增殖的生态位。
Understanding the occurrence and consequence of co-infections can be useful in designing disease management interventions. Amphibians are the most highly threatened vertebrates, and emerging pathogens are a serious threat to their conservation. The amphibian chytrid fungus and the viruses of the Ranavirus genus are already widely distributed, causing disease outbreaks and population declines worldwide. However, we lack information about the occurrence and consequences of coinfection with these pathogens across age-classes of amphibian hosts. Here, we analyze the occurrence of infection of the amphibian chytrid fungus and ranaviruses during one season in two susceptible amphibian species at two different locations at which outbreaks have occurred. We found that the co-occurrence of both pathogens in a particular host is not common except in highly susceptible life-stages, and that single infections are the most common situation. Moreover, we found that the occurrence of one pathogen in a particular host did not predict the occurrence of the other. We attribute these results to the niches in which both pathogens proliferate in amphibian hosts.
