Yet no one seems to have even investigated the possibility, until very recently. Textbooks of parasitology provide ample material on the interactions between various species of Ascaris and their hosts - but virtually nothing about how the worms themselves cope with the microbial population surrounding them.
Now, thanks to the efforts of Professor A C Wardlaw and collaborators in the microbiology and zoology departments at the …
