[Natural infection of Speothos venaticus (Carnivora: Canidae) by adult stages of Lagochilascaris sp].
An adult male Speothos venaticus Lund (bush dog) was found killed on a rural road in the Northeast of Bolívar State, in a locality where a patient with lagochilascariasis has lived for the past 16 years. The animal was frozen for 1 month, and after removal of the head and skin, was autopsied. Two adult gravid females of Lagochilascaris sp. were found in the trachea. Certain morphological characteristics of the soft parts differed from the description given for Lagochilascaris minor Leiper, 1909; however, stable characters, such as the form of the interlabials, the location of the vulva, and particularly the size and number of depressions of the egg shell appear to indicate that the worms are of the above mentioned species. Unfortunately, no males were found for study of the spicules and ejaculatory duct. In histological sections of the larynx and the trachea from the deep tissues, parts of degenerated worms were found, with characteristics attributable to Lagochilascaris sp.
