Horizontal transfer of parasitic sex ratio distorters between crustacean hosts [PDF]

open access: yes, 1998
Parasitic sex ratio distorters were artificially transferred within and between crustacean host species in order to study the effects of parasitism on host fitness and sex determination and to investigate parasite–host specificity. Implantation of Nosema
