Comparison of the pathogenicity of Mycobacterium paratuberculosis and Mycobacterium spp isolated from the wood pigeon (Columba palumbus-L).
The pathogenicity of 4 strains of mycobacteria isolated from wood pigeons and 2 strains of Mycobacterium paratuberculosis was compared in calves, mice and chickens. Three of the 4 wood pigeon strains and the 2 M. paratuberculosis strains produced clinical Johne's disease in calves. All 6 strains were pathogenic for mice and the 4 wood pigeon strains were pathogenic for chickens. The strains were not agglutinated by antisera to strains of the M. avium complex and all were mycobactin-dependent. It was concluded that the wood pigeon isolates may constitute a distinct group with the pathogenic capability of M. avium in chickens and M. paratuberculosis in calves.
