Shigella dysenteriae type 1 enterocolitis.

Shigella dysenteriae type 1 is much more virulent than Shigella flexneri and sonnei which are endemic in Australia. This report describes a 22 year old woman who acquired Shigella dysenteriae type 1 whilst travelling in India. During the course of her illness, she developed severe enterocolitis for which a subtotal colectomy was performed. The illness resembled fulminant ulcerative colitis and its infectious nature was difficult to establish because several fecal cultures failed to grow the pathogen. Her infection was complicated by shigella bacteremia, disseminated intravascular coagulation, and renal cortical necrosis which requires continued hemodialysis.
