Lung abscess and osteomyelitis of rib due to Yersinia enterocolitica

The first reported case of infection of the lung and bone with Yersinia enterocolitica is described. This organism has only recently been known to infect humans. Although a wide spectrum of diseases has been described, all have appeared to be relatively benign; however, in our case a rapid necrotizing process occurred. Therefore, the aggressive nature of this organism outside its usual surroundings, eg, the gastrointestinal tract, is worth noting.
