Necrotizing pneumonia and pleuritis associated with extraintestinal pathogenic Escherichia coli in a tiger (Panthera tigris) cub.

Extraintestinal pathogenic Escherichia coli (ExPEC) cause diseases in humans and animals, affecting organs outside the alimentary canal. In recent years, ExPEC have been reported as a cause of fatal pneumonia in dogs, cats, and in a horse. In the current report, a fatal case of pneumonia and pleuritis is described in a 4-week-old tiger (Panthera tigris) cub associated with ExPEC.
