The purpose of the study was to identify the endohelminths of the native fish Galaxias maculatus and Basilichthys australis in Lake Pullinque Chile, determine their prevalence, mean intensity, mean abundance, their zoonotic potential, describe new taxa for Chile, and evaluate the potential histopathological changes in parasitized samples of intestine of B. australis. Trematodes (Steganoderma szidati, Acanthostomoides apophalliformis, Tylodelphys sp, Posthodiplostomum sp) nematodes (Contracaecum sp, Camallanus corderoi and Eustrongylides sp) and the acanthocephalan Acanthocephalus tumescens was reported in G. maculatus. Tylodelphys sp presented the highest prevalence (97%) and mean abundance (21.1), while Posthodiplostomum sp showed the highest mean intensity (33.5). Trematodes (Limnoderetrema tolosai, Austrodiplostomum mordax and Tylodelphys destructor) and nematodes (Contracaecum sp, Hy...
