Final answer:
Information provided pertains to helminth parasites like Strongyloides stercoralis causing strongyloidiasis and Enterobius vermicularis leading to enterobiasis. It describes their transmission methods and life cycles but does not compare the numbers of large versus small strongyles. The details emphasize the importance of hygiene to prevent transmission of common intestinal parasites.
Step-by-step explanation:
Though the question pertains to the prevalence of large strongyles versus small strongyles, the provided information does not directly address the comparative numbers of these parasites. However, it does offer insight into different types of helminth parasites and their methods of transmission and life cycles, which can provide context to understanding helminth infections like strongyloidiasis and enterobiasis.
Strongyloidiasis is generally caused by Strongyloides stercoralis, with transmission occurring through soil when larvae penetrate the skin. They can migrate to the lungs and then to the intestine. In contrast, enterobiasis is caused by Enterobius vermicularis (nematode pinworms) that are transmitted via the fecal-oral route.
The life cycles of helminths such as nematodes and tapeworms (cestodes) involve various hosts and environments. Common routes of transmission include consumption of undercooked meat or exposure to contaminated soil, showing the importance of food and environmental hygiene in preventing such infections.
It is important to note that the details provided suggest that nematodes are common intestinal parasites, and while large strongyles (also nematodes) are not explicitly mentioned, the information provided serves as a foundation to understand how parasitic infections occur, spread, and could be managed in humans and animals.
