| postlarval protopolystoma spp. kidney infections in incompatible xenopus spp. induce weak resistance to heterospecifics. | protopolystoma xenopodis and protopolystoma orientalis are polystomatid monogeneans respectively specific to the parapatric anurans xenopus laevis and xenopus muelleri. parasite larval stages may invade the kidneys of foreign xenopus spp. but die before migration to the definitive urinary bladder site. laboratory experiments to assess the effect of a primary incompatible kidney infection on a secondary compatible infection found: (1) a small, significant decrease in the survivorship of p. xenopo ... | 2003 | 12759746 |
