This faecal specimen was obtained from a 50 year old man from Charleville, western Queensland. He reports vague abdominal discomfort and periodic bouts of nausea. The patient lives in a small caravan on the outskirts of the town which he shares with a group of dogs, and he has a reputation as being a "hobo". Health inspectors report the living conditions as "squalid", with rats and mice prevalent.
