Efectos producidos por Spinitectus jamundensis (Nematoda, Cystidicolidae) en el estómago del sábalo, Prochilodus lineatus (Pisces, Prochilodidae)
The presence of the nematode Spinitectus jamundensis in cardial and pyloric regions of the stomach of Prochilodus lineatus is observed. Samples of the parasitated stomach were analyzed by histological techniques using Hematoxilin-Eosin and Mallory (Azan) Heidenhain's stainnigs. The macroscopica...
