RESUMO

The study describes some morphological trait of Taxorchis schistocotyle Beddard, 1914 (Trematoda, Cladorcniidae) using scanning electron microscope (SEM). Specimens were removed from small instestine during necropsy of Hydrochoeris hydrochaeris (Rodentia, Hydrocheoridae). Samples were fixed in glutaraldehid 3 percent in sodium monoacid phosphate buffer with dehidratation in acetones of increasing graduation. Diagnosis technique used was useful to survey and differentiation among species that parasite Argentinean wild mammalians.

RESUMO

With the objective to determine the infection frequency by coccidia protozoa, 159 fecal samples from captive wiid camivores were analyzed. A 10.7 percent of the animal analyzed were positive to the infection. Whereas the family Procyonidae has a high percentage of positivity (35 percent), Canidae have lower infection ratio (23-33 percent) and Felidae only 0.3 percent). Family Musteldiae show negative findings

RESUMO

With the aims to determine the infection frequency by tapeworms of Diphyllobothrium genus 30 samples from captive wild carnivores were analyzed. A 30 percent of the animal analyzed was positive to the infection. Whereas the family Procionidae has a high percentage of positivity (60 percent). Canidae have lower infection ratio (20-25 percent). The accuracy for the diagnosis of Diphylobothrium was made by the morphology of scolex, proglottids and eggs. This is the first report of the parasite presence in Argentine wild carnivores
