strongyloids, pinworms, threadworms, hookworms, and ascaris are co-infectious and tend to work together in the same hosts
the big ones are probably hooks and/or ascaris, however
imho, just guessing
seems i read somewhere that strongyloids are pretty small
they apparently get in the blood, weaken tissues, and make it easier
for the big ones to take a strong hold, which is probably how they
got their name...
