The laboratory analysed a stool culture and found that it was negative for all bacterial and viral diseases tested, including cholera. In the lab, a standardised, concentrated sample of stool was made, stained with iodine, and seen using light microscopy at magnifications of x100 and x400. Oval, non-moving cysts that were about 10µm x 8 µm in size were seen. Provide a differential and presumptive diagnosis.
A 20-year-old student who spent six months working in India and trekking in the forests of Chang Mai, Thailand before returning home to the UK two months ago. Before she left the UK she obtained all recommended vaccines, such as typhoid and hepatitis A. On her trip, she experienced occurrences of diarrhoea, which cleared up without treatment.
