Fifteen high school students visited a local farm in central Wisconsin for a weekend where they enjoyed petting farm animals, riding horses, and campfire meals
With sanitation in mind, only one individual remembered to wash her hands with water pumped from a well after petting the animals before dinner. After two weeks of the girl passing out at random occasions, she was rushed into the emergency room where doctors determined she was severely dehydrated. Explain how it took direct observation of a fecal sample to solve this potential life-threatening disease and how this disease was treated in the otherwise healthy girl. Also mention any necessary precautions the individual should have taken after being diagnosed with the disease.
What will be an ideal response?
Answer: The protozoan pathogen Cryptosporidium parvum usually goes undetected from traditional clinical diagnostic tests, so the direct observation of Cryptosporidium oocysts in fecal matter was used to diagnose cryptosporidiosis. The disease generally subsides in healthy individuals within two weeks, so a doctor likely did not prescribe any medication but suggested to the patient to remain fully hydrated by drinking a lot of liquids. The girl likely was shedding oocysts for several weeks following infection, so she would need to be especially mindful not to spread the infectious agents to any others.
