A 65-year-old patient comes in for a check-up and when you ask if there's been anything unusual, he quietly says that that's why he stopped by. He found something strange in his fecal matter that seemed to be moving. From his description, you suspect that it was a proglottid. What infectious agent do you believe caused this? Is it unusual for an individual to have no discernable symptoms with this infection? How was he likely infected? What is unique about how these infections occur when compared to the majority of fecal-orally transmitted pathogens we've discussed? Some other parasites such as hookworms have another unique transmission mechanism, describe this. How would you prevent these infections?
