Salmonella newport causing osteomyelitis in a patient with diabetes

Salmonella is a foodborne pathogen that commonly causes intestinal symptoms. Bacteraemia and extraintestinal infections have been documented within the literature, and are more frequently associated with immunodeficiency and general debilitation. We discuss the case of a previously well 36-year-old man who presented with a septic knee and new-onset diabetes. Imaging confirmed osteomyelitis and a Brodie's abscess, with blood and tissue cultures revealing the isolate Salmonella enterica newport. He denied any previous gastrointestinal symptoms, recent travel, change in usual dietary habit or symptoms of diabetes. So far there have only been three reported cases of S. newport causing osteomyelitis. We discuss the incidence of Salmonella infections, including extraintestinal symptoms, its relation to immunodeficiency and the disease burden of S. newport.
