Helmintofauna em Cerdocyon thous Linnaeus, 1766 (Carnivora, Canidae) na região de Juiz de Fora, Minas Gerais

Abstract

Cerdocyon thous is a canid of neotropical fauna, with nocturnal habits and extensive distribution in the savannas and forests of South America. The objective of this work is contribute for the knowledge about helminthes species in C. thous. Were examined six specimens of C. thous dead by running over in the periphery of the Juiz de Fora, Minas Gerais, Brazil. The helminths was collected and stored in 70 % alcohol and dry preparations. For specific identification, they were prepared in permanent and no permanent slides. Angiostrongylus vasorum (Baillet, 1866) Kamensky, 1905 (Nematoda, Angiostrogylidae) occurred in heart and lungs in tree hosts, with a prevalence of 50% (P=50%), mean abundance of 4±4,47 (MA=4±4,47), mean intensity of 8±3,00 (MI=8±3,00) and spatial distribution agregated (ID=5,70 e K=0,36). This species has been characterized as secondary in the community of parasites. Platynosomum illiciens (Braun, 1901) Kossack, 1910 (Digenea, Dicrocoeliidae) (P=16,7%; MA= 6±14,69; MI= 36) occurred in liver of one host and was categorized as satellite among parasites populations. Ancylostomma bucklelyi Le Roux and Biocca, 1957 (Nematoda, Ancylostomatidae) (P=33,4%; MA= 2±3,09; MI= 6) occurred in small intestine and stomach in two hosts, with spatial distribution agregated (ID=0,57;

K=6,32), and was categorized as secondary. Pterygodermatites affinis (Jägerskiöld 1904) Quentin, 1969 (Nematoda, Rictulariidae) (P=66,7%; MA= 5±7,64; MI= 7,5±8,5), was registered in intestine and stomach in four hosts and showed spatial distribution agregated (ID=0,56 e K=0,44). P affinis was the only central species in the parasites community. Athesmia heterolecithodes (Braun, 1899) Looss, 1899 (Digenea, Dicrocoeliidae) (P=33,4%; MA= 59,83±140,76; MI= 179,5±236,88), a secondary parasites species, was registered in liver of the two host. A not identify species of nematodes Capilariidae was recorded in one host. This study are the first record of A. heterolecithodes, P. affinis, P. illiciens in C. thous.
