An Atypical Enteropathogenic Escherichia coli Isolate with Possible Human and Domestic Animal Origin from a Free-Living Lear's Macaw (Anodorhynchus leari)

An atypical enteropathogenic Escherichia coli was isolated from an asymptomatic nestling of the endangered Lear's Macaw (Anodorhynchus leari). Phylogenetically, it was identical to bovine and human strains and highly similar to other human and domestic animal isolates. We discuss potential routes of transmission and risks to conservation of this species.
