Genome analysis of a bacterium that causes lameness.

Lameness is a significant problem resulting in millions of dollars in lost revenue annually. In commercial broilers, the most common cause of lameness is bacterial chondronecrosis with osteomyelitis (BCO). We are using a wire flooring model to induce lameness attributable to BCO. We used 16S ribosomal DNA sequencing to determine that Staphylococcus spp. were the main species associated with BCO. Staphylococcus agnetis, which previously had not been isolated from poultry, was the principal species isolated from the majority of the bone lesion samples. Administering S. agnetis in the drinking water to broilers reared on wire flooring increased the incidence of…
