“…However, these clinical signs are typically described for chickens (Gallus gallus domesticus), with infections in wild avian species rarely reported and not well described; therefore, we cannot be certain that wild avian species would experience the same clinical signs. For example, a recent study reported severe periocular swelling, periocular skin crusting, fibrinous sinusitis, and conjunctivitis in wild turkeys infected with a novel clade of Avibacterium (38). The presence of multiple pathogenic agents also makes it difficult to determine the contribution of different microbes.…”

Mass mortality events in wildlife can be indications of an emerging infectious disease. During the spring and summer of 2021, hundreds of dead passerines were reported across the eastern US. Birds exhibited a range of clinical signs including swollen conjunctiva, ocular discharge, ataxia, and nystagmus. As part of the diagnostic investigation, high-throughput metagenomic next-generation sequencing was performed across three molecular laboratories on samples from affected birds. Many potentially pathogenic microbes were detected, with bacteria comprising the largest proportion; however, no singular agent was consistently identified, with many of the detected microbes also found in unaffected (control) birds, and thus considered to be subclinical infections. Congruent results across laboratories have helped drive further investigation into alternative causes including environmental contaminants and nutritional deficiencies. This work highlights the utility of metagenomic approaches in investigations of emerging diseases and provides a framework for future wildlife mortality events.
