Resumo
The occurrence of gastrointestinal nematodes affecting a Magellanic penguin, which was submitted to necropsy after being found dead at the coast of Vitória, Espírito Santo State, Brazil, was reported. A great number of juveniles nematodes and 48 adults (24 males and 24 females) were found in the stomach of the penguin. The parasite was diagnosed as Contracaecum pelagicum in agreement with the number and the distribution of the precloacal and postcloacal papillae of the male specimens. Other characteristics as distribution of the labial papillae, intestinal caecum and ventricular appendix ratio, spicules length, and total body length ratio were also in accordance to the well-known variation for the species, confirming the diagnosis. This work is the first report of the parasitism by C. pelagicum in Magellanic penguin found in the Southeast of Brazil.(AU)

The anthelminthic activity of four plants - Allium sativum (garlic), Punica granatum (pomegranate), Tynnanthus labiatus (liana-carnation) and Cocus nucifera (coconut) with the activity of mebendazole was compared. Seventy Hubbard chickens, naturally infected with Ascarídia galli, divided in 5 groups of 10 chichens plus a control group (not treated, n=20) were used in the experiment. The vegetable matter was used in the forms of aqueous extract, juice and triturated, administered by probe or incorporated to the diet, in the doses of 2, 3 and 10g/kg/day, for three days. A non parametric test was used to evaluate the anthelminthic effect of the plants. The eliminations of A. galli for the garlic, pomegranate, liana-carnation, coconut and mebendazole were: 9.7; 6.6, 16.7; 19.0 and 99.0%, respectively. The results showed that those plants do not have anthelminthic activity.(AU)
