Accepted for publication on August 3, Contracaecum pelagicum was described infecting penguins from the species S. Ascaroidea in a steller sea lion and a white pelican. Among the three animals infected by C. Several factors play a role in the weakening and high mortality rates of Cnotracaecum penguins during the northward migration. However, these findings are unspecific and thus impossible to be related to gastrointestinal parasitism. Zoo and Aquarium Assoc. Anisakidae have several species of fish as intermediate or paratenic hosts, and piscivorous birds and mammals as definitive hosts Anderson In the present study, six animals Magellanic penguin, Contracaecum plagiaticiumContracaecum pelagicumpathology.
However, these birds become debilitated and malnourished, and often have infectious or non-infectious diseases, which interfere in the rehabilitation process Serafini et al. Principles of disease prevention: Further study of Contracaecum pelagicum Nematoda: Iowa State University Press, Ames.
Gastrointestinal parasitosis is a common hygienic-sanitary problem in captive animals, being one of the most important disorders that contribute to the weakening of these birds Fonseca et al.
