The tirst section refers to the survey ofthe species, related to 21 superfamilies, 45 families, 160 genera and 495 species that are illustrated and measurement tables are given. The second section is concerned to the catalogue ofhost mammals which includes 34 families, 176 species and their respective parasite nematodes. The identification ofthese helminths is achieved by means ofkeys to the superfamilies, families and genera. Specific determination is induced through the figures and tables as above mentioned.

The first scclion rcfcrs to the catalogation af lhe species, related to 127 superfamilics, 23 families, S5 genera and 121 spedes lha! are figurcd and includcd in measurement tables. The second sc:clion is concemed to the catalogue af host reptiles, with 16 families, and 90 species and their respective parasite nematodes. The identification ofthese hclminths is achieved bymeans ofl.:eys to lhe superfamilies, families and genera. Specific determinalion is induced through lhe figures and tables as above mentioned.

Nematodes from opossums and rodents captured in the Brazilian Atlantic Forest in the State of Rio de Janeiro, Brazil were studied. From the opossums Didelphis aurita Weid-Neuweid, 1826 and Philander opossum (Linnaeus, 1758) the following nematode species were recovered: Viannaia hamata Travassos, 1914, Aspidodera raillieti Travassos, 1913, Cruzia tentaculata (Rudolphi, 1819), Travassos, 1917, Turgida turgida (Rudolphi, 1819) Travassos, 1919, Gongylonemoides marsupialis (Vaz & Pereira, 1934) Freitas & Lent, 1937, Viannaia viannai Travassos, 1914, Spirura guianensis (Ortlepp, 1924) Chitwood, 1938 and from the rodents Akodon cursor (Winger, 1887), Nectomys squamipes (Brants, 1827), Oligoryzomys eliurus (Wagner, 1845) and Oryzomys intermedius (Leche, 1886): Hassalstrongylus epsilon (Travassos, 1937) Durette-Desset, 1971, Syphacia obvelata (Rudolphi, 1802) Seurat, 1916, S. venteli Travassos, 1937, Physaloptera bispiculata Vaz & Pereira, 1935, Litomosoides carinii (Travassos, 1919) Vaz, 1934, Viannaia viannai, Hassalstrongylus epsilon, H. zeta (Travassos, 1937) Durette-Desset, 1971, Stilestrongylus aculeata (Travassos, 1918) Durette-Desset, 1971 S. eta (Travassos, 1937) Durette-Desset, 1971. Highest worm burdens and prevalences were those related to Cruzia tentaculata in marsupials. Stilestrongylus aculeata was referred for the first time in Akodon cursor

INTRODUÇÃOEm seqüência ao inventário dos nematóides parasitas que ocorrem no Brasil, iniciado por Vicente et al., em 1985, o presente trabalho relaciona·se às espéCies de nematóides parasitas de anfíbios.Neste trabalho, procuramos seguir a mesma orientação apresentada no anterior sobre nemat6ides de peixes.Para a organização dos diferentes nematóides aqui apresentados, seguimos basicamente a sistemática de Yamaguti (1961) com as modificações propostas por Hartwich (1974), Chabaud (1975Chabaud ( e 1978, Anderson e 8ain (1976Anderson e 8ain ( e 1982, Lichtenfels (1980), Moravec (1982) e Durette-Desset (1983).Para identificação das superfamílias, famílias e gêneros dos nemat6ides, damos chaves de determinação e principais características das famílias e gêneros aqui estudados. As chaves são em parte originais, e em parte ·adaptadas de outros autores.Para melhor auxiliar na identificação específica apresentamos quádros de medidas e fJgUras, além das referências bibliográficas relativas a cada espécie.No Foram conservados os nomes específicos dos anfíbios originalmente reportados, colocando-se entre parêntesis, quando pertinente, a designação atual, antecedida do sinal de igualdade. Sendo a sistemática atual dos anfíbios dependente muitas vezes de sua distribuição geográfica e devido ao fato de que a espécie hospedeira, referida em alguns trabalhos, não ocorre na área originalmente indicada como local de captura, havendo possibilidade de que outra possa ser considerada para a região mencionada, adotamos o crité-rio de colocar, também entre parêntesis, ap6s o nome da espécie ,citada originalmente, o nome da espécie válida ou da provável espécie do hospedeiro que ocorre na localidade. HISTÓRICOAs primeiras referências sobre nematóides parasitas desse grupo de vertebrados, encontrados em territ6rio brasileiro, são representadas por amostras coletadas por cientistas estrangeiros, principálmente por Natterer, na primeira metade do século XIX, e que foram estudadas por helmintologistas europeus.

In this survey 1,500 samples of nematodes, representing 151 species, distributed in 20 superfamilies, parasitizing Brazilian mammals (Artiodactyla, Carnivora, Chiroptera. Edentata, Lagomorpha, Marsupialia, Perissodactyla, Primates, Rodentia) and deposited between 1916-1963 in the CHIOC were studied. New host records were established for 52 Parasite species distributed in 15 superfamilies, adding new data to previous reports of mammalian nematodes in Brazil

The helminth fauna of two sympatric congeneric skinks (Mabuya agilis and M. macrorhyncha) from two distinct "restinga" habitats (Praia das Neves and Grussaí) in southeastern Brazil were studied, totalling four data sets (sample sizes ranging from 11 to 28). A total of ten helminth species were associated with the skinks: Raillietiella sp., Paradistomum parvissimum, Pulchrosomoides elegans, Oochoristica ameivae, Hexametra boddaertii, Parapharyngodon sceleratus, Physalopteroides venancioi, Physaloptera sp., an unidentified acuariid nematode and an unidentified centrorhynchid acanthocephalan. Except for Hexametra boddaertii (found only in Grussaí) and Pulchrosomoides elegans (found only in Praia das Neves), all helminth species were present at both localities. Half of the helminth species were present only as larvae and, in most cases, appear to represent paratenic parasitism. Overall prevalences of infection were high for both host species in both localities. Mabuya agilis tended to have richer and more diverse infracommunities than M. macrorhyncha. Some parameters of infection by individual helminth species seem to be related to the ecology of each Mabuya species. The parasite faunas were qualitatively very similar among species and/or localities, but quantitative similarities were more varied, due to differential representativeness of individual helminth species among host populations. The helminth communities of both skink species can be classified as non-interactive, being composed of site-specialists and immature stages of non-lizard parasites.

The spectrum of intestinal parasites present in the Swiss Webster, C57B1/6 and DBA/2 mice strains from different animal houses was identified and prevalences compared. Three parasites were observed during the course of this study, namely the cestode Vampirolepis nana (Siebold, 1852) Spasskii, 1954 (= Hymenolepis nana) and the nematodes Aspiculuris tetraptera (Nitzsch, 1821) Schultz, 1924 and Syphacia obvelata (Rudolphi, 1802) Seurat, 1916. The scope of this investigation has been widened to also include morphometric data on the parasites, to further simplify their identification, since the presence of helminths in laboratory animals is regarded as a restricting factor for the proper attainment of experimental protocols.
