Fig. 1From: Nematode infection in liver of the fish Gymnotus inaequilabiatus (Gymnotiformes: Gymnotidae) from the Pantanal Region in Brazil: pathobiology and inflammatory response a Photograph during necropsy; several encysted larvae (arrows) of the nematode Brevimulticaecum sp. are visible on liver of Gymnotus inaequilabiatus. b Very heavily infected liver shown during necropsy examination; the larva appeared as single (arrows) or in clusters (arrowheads) beneath the serosa. c Small piece of fixed liver free of larvae; smooth surface of organ is appreciable. d Cluster of Brevimulticaecum sp. third-stage larva in cysts (arrows) covered by serosa are evident. Note the difference between surfaces of liver in (c and d). e Encysted larva on surface of liver (arrow), and numerous larvae inside the cyst attached to the liver by a peduncle (curved arrow).
