Investigation of factors predicting disease among zoo birds exposed to avian mycobacteriosis

Abstract

Objective—To characterize infection patterns and identify factors associated with avian mycobacteriosis among zoo birds that were housed with infected enclosure mates. Design—Matched case-control study. Animals—79 birds with avian mycobacteriosis (cases) and 316 nondiseased birds (controls) of similar age and taxonomic group that were present in the bird collection of the Zoological Society of San Diego from 1991 through 2005….
