skin manifestations in parasite infection.	intestinal parasites stimulate ige synthesis by their proteinases. because of their ability to induce ige production and mast cell degranulation (either directly, e.g. ascaris, or via specific ige) it is possible that some parasites induce allergic manifestations. some parasites may be more allergenic than others due to their allergenicity. genetic predisposition, nutritional status, and psychosocial variables of the host and the time and degree of allergen exposure may also play an important ro ...	2001	12561678

evolution of ascariasis in humans and pigs: a multi-disciplinary approach.	the nematode parasite ascaris lumbricoides infects the digestive tracts of over 1.4 billion people worldwide, and its sister species, ascaris suum, has infected a countless number of domesticated and feral pigs. it is generally thought that the putative ancestor to these worms infected either humans or pigs, but with the advent of domestication, they had ample opportunity to jump to a new host and subsequently specialize and evolve into a new species. while nuclear dna makers decisively separate ...	2003	12687761
