Abstract
Salmonellosis is an infection caused by the members of the genus Salmonella, which are Gram negative bacilli. This may manifest as gastroenteritis, bacteremia and focal lesions. Focal Salmonella infection can occur with or without sustained bacteremia causing abscess formation along with clinical features of inflammation such as swelling and pain. The commonly involved systems include gastrointestinal system, vascular system, urinary system and uncommonly involved sites are pericardium, meninges, joints, bones, and lymphatic system. Here we present a case of a submandibular abscess caused by Salmonella species, in a 42 year old male diabetic with poor glycemic control.A 42 Year old male who was a known case of type 2 Diabetes mellitus on poor glycemic control was admitted to the surgical ward with the complaints of continuous fever for 5 days followed by swelling associated with pain in the right submandibular region. Pus culture and sensitivity yielded smooth, grey white, non haemolytic and non pigmentedcolonies on Blood Agar and non lactose fermenting colonies in Mac’Conkey agar. Inoculation was made on selective medium Salmonella Shigella agar which was incubated at 37 for 24 hours and Jet black colonies were observed after the incubation time. The culture of the pus sample yielded Salmonella species.
