One of our local hospitals had Strongyloides worms in a sputum specimen. They
wriggled all over the plate leaving bacterial trails on the media as they
went. Obviously they travel. I don't know much else about the epidemiology of
this worm. I probably should look it up. The ASM Manual is a good place to
start (American Society of Microbiology).
