Aplectana comprises species of gastrointestinal helminths commonly found parasitizing amphibians and reptiles worldwide. However, most species of the genus are described based only on morphological traits. During helminthological surveys, we found nematodes identified as Aplectana pella parasitizing the hylid frog Osteocephalus cabrerai from the sa...
Surface flow of freshwater on Adriatic islands is rare due to the extreme permeability of the karst terrain. Hence, most helminthological studies of freshwater fishes in the Adriatic drainage have focused on mainland freshwater systems, while data from islands are scarce. We collected minnow, Phoxinus lumaireul (Schinz, 1840), specimens in the Suha...
Although surveys on bat parasites in the Americas have been conducted, information on helminths remains limited.
