A presente nota fornece dados atuais a respeito de helmintos coletados por Adolpho Lutz (Instituto Bacteriológico de São Paulo) entre 1905-1909, estudados por Travassos (1917) e, segundo o autor, depositados na Coleção Helmintológica do Instituto Oswaldo Cruz (CHIOC). No presente trabalho, algumas incorreções contidas na publicação de Travassos (1917) e que passaram despercebidas até a presente data, são consideradas e elucidadas.

This note supplies recent data on the present status of helminths collected by Adolpho Lutz (Bacteriological Institute of São Paulo) between 1905-1909, studied by Travassos (1917) and referred by the author as deposited in the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC). In the present paper, some innacuracies related to the paper of Travassos (1917) and that have been overlooked to date are evaluated and elucidated.

O trematódeo digenético Psilochasmus oxyurus (Creplin, 1835) Lühe, 1909, embora de ampla distribuição geográfica, é referido em gansos (Anser anser Linnaeus, 1758) pela primeira vez na América do Sul, com base em espécimes coletados em gansos domésticos no Brasil, com prevalência de 20%. Dados morfométricos gerais dos parasitos são incluídos. Não foram observados sinais clínicos, macro lesões ou alterações histopatológicas nas aves.

The digenetic trematode Psilochasmus oxyurus (Creplin, 1835) Lühe, 1909, although with a large geographical distribution, is referred in geese (Anser anser Linnaeus, 1758) for the first time in South America, on the basis of specimens parasitizing Brazilian domestic geese, with a prevalence of 20%. Brief morphometric data on the parasites are included. Clinical signs, gross and microscopic lesions were not observed in the birds.

This study refers to the helminth fauna of the Spotted Nothura, Nothura maculosa (Temminck, 1815), on the basis of samples deposited in the Helminthological Collection of the Oswaldo Cruz Institute, and also on bibliographical data. The helminth survey of N. maculosa is represented by the digenetic trematode Brachylaemus (Centrodes) centrodes (Braun, 1901) Travassos & Kohn, 1964, by two cestode species, one included in Hymenolepis Weiland, 1858 and the other identified as Fuhrmannetta elongata (Fuhrmann, 1908), by the nematodes Heterakis gallinarum (Schrank, 1788) Freeborn, 1923, Heterakis spiculatus (Cobbold, 1861) Travassos, 1918, Subulura olympioi Barreto, 1918, Eucoleus penidoi Freitas & Lins, 1935, Hadjelia curvata Vaz & Pereira, 1935, Hempelia hempeli Vaz, 1936, Tetracheilonema quadrilabiatum (Molin, 1858), one species included in Capillaria Zeder, 1800, and another in Trichostrongylidae Leiper, 1912; the acanthocephalan is represented by Mediorhynchus pintoi Travassos, 1923. Fuhrmannetta elongata is referred for the first time in this host since its proposal in 1908. There is a report of the finding of the habronematid nematode Procyrnea cameroni Gupta & Kazim, 1978 from N. maculosa in Brazil; the species is not illustrated taking into account the status of the original reference. The probable occurrence of the digeneans Prosthogonimus ovatus (Rudolphi, 1803), Athesmia heterolecithodes (Braun, 1899) Looss, 1899, and the nematode Heterakis brasiliana Linstow, 1899, is indicated

Este estudo diz respeito à fauna helmintológica da codorna-comum Nothura maculosa (Temminck, 1815) e é baseado em amostras depositadas na Coleção Helmintológica do Instituto Oswaldo Cruz (CHIOC) e, também, em dados bibliográficos. A helmintofauna de N. maculosa é representada pelo trematódeo digenético Brachylaemus (Centrodes) centrodes (Braun, 1901) Travassos & Kohn, 1964, por duas espécies de cestóides, uma incluída em Hymenolepis Weinland, 1858, e a outra identificada a Fuhrmannetta elongata (Fuhr-mann, 1908), por nematóides identificados a Heterakis gallinarum (Schrank, 1788) Freeborn, 1923, Heterakis spiculatus (Cobbold, 1861) Travassos, 1918, Subulura olympioi Barreto, 1918, Eucoleus penidoi Freitas & Lins, 1935, Hadjelia curvata Vaz & Pereira, 1935, Hempelia hempeli Vaz, 1936, Tetracheilonema quadri-labiatum (Molin, 1858), uma espécie incluída em Capillaria Zeder, 1800 e outra em Trichostrongylidae Leiper, 1912; o acantocéfalo é representado por Mediorhynchus pintoi Travassos, 1923. Fuhrmanneta elongata é referida pela primeira vez neste hospedeiro desde a sua proposição em 1908. A possível ocorrência dos trematódeos digenéticos Prosthogonimus ovatus (Rudolphi, 1803), Athesmia heterolecithodes (Braun, 1899) Looss, 1899 e dos nematóides Heterakis brasiliana Linstow, 1899, Procyrnea cameroni Gupta & Kazim, 1978 é indicada. Há um registro do encontro de um nematóide habronematídeo Procyrnea cameroni Gupta & Kazim, 1978 de N. maculosa no Brasil, espécie que não é ilustrada, considerando-se a informalidade da citação

The pathology induced by the nematode Camallanus cotti in the aquarium fishes Beta splendens (beta fish) and Poecilia reticulata (guppy) consisted of gross and microscopic lesions, the former characterized by abdominal swelling with reddish parasites protruding from the anus in both fish hosts and the latter, similar in the beta fishes and guppies, by hemorrhage, congestion, edema, a few glandular elements, and extensive erosion areas in the rectum mucosa, with a marked thickening of the wall and absence of inflammatory infiltrate. Lesions were associated with the presence of several worms attached to the wall or free in the rectal lumen. This is the second reference of the parasite in Brazil and the first report of pathological findings related to this nematode species that is also briefly redescribed and illustrated for the first time on the basis of Brazilian samples.

A atual situação de depósito de duas espécies-tipo de nematóides, Cruzia tentaculata (Rudolphi, 1819) e Katlania leptura (Rudolphi, 1819), agora incluídas na Coleção Helmintológica do Instituto Oswaldo Cruz, é informada.

The present deposit status of two nematode type species, Cruzia tentaculata (Rudolphi, 1819) and Katlania leptura (Rudolphi, 1819), now included in the Helminthological Collection of the Oswaldo Cruz Institute is informed.

Os presentes resultados relacionam-se ao primeiro relato de infecção natural por helmintos na codorna doméstica, Coturnix japonica Temminck & Schlegel, 1849 no Brasil. O trematódeo renal Tanaisia inopina Freitas, 1951 é assinalado pela primeira vez nesta espécie de ave.

The present findings are related to the report of the first natural helminth infection in the Japanese quail, Coturnix japonica Temminck & Schlegel, 1849 in Brazil. The kidney trematode Tanaisia inopina Freitas, 1951 is referred for the first time in the investigated host.

A presente nota se destina a corrigir informações anteriores a respeito da condição da Coleção Helmintológica do Instituto Pasteur, que é, de fato, uma coleção institucional e que foi designada, erroneamente, como um acervo particular incorporado à Coleção Helmintológica do Instituto Oswaldo Cruz. Também, dados bibliográficos e históricos são retificados.

This note is to correct previous information about the status of the Helminthological Collection of the Pasteur Institute, that is, in fact, an institutional collection, and that appeared erroneously as a private survey incorporated to the Helminthological Collection of the Oswaldo Cruz Institute. Also, bibliographical and historical data are rectified.

Trinta e cinco amostras de helmintos coletadas de Oryctolagus cuniculus (Linnaeus, 1758) Lilljeborg, 1873 (3) e de uma outra espécie de coelho, Sylvilagus brasiliensis (Linnaeus, 1758) Thomas, 1901 (32), de agosto de 1909 a fevereiro de 1948 e que estão depositadas na Coleção Helmintológica do Instituto Oswaldo Cruz, foram analisadas. As amostras estudadas estão representadas pelo cisticerco do cestóide Taenia pisiformis (Bloch, 1780) e pelos nematóides Passalurus ambiguus (Rudolphi, 1819), Vianella fariasi (Travassos, 1915), Longistriata perfida Travassos, 1943, Trichostrongylus retortaeformis (Zeder, 1800). O objetivo da presente investigação é o de inventariar os parasitos que infectam estes hospedeiros, comumente utilizados como modelos de animais de laboratório na pesquisa científica e fornecer dados figurativos sobre os helmintos a fim de facilitar sua identificação, uma vez que, cargas parasitárias autóctones, caso não detectadas ou erroneamente avaliadas, podem alterar o resultado final de protocolos experimentais, principalmente dos relacionados a ensaios imunológicos, quando infecções cruzadas podem ocorrer.

Helminth samples (n = 35) recovered from Oryctolagus cuniculus (Linnaeus, 1758) Lilljeborg, 1873 (3) and from another rabbit species, Sylvilagus brasiliensis (Linnaeus, 1758) Thomas, 1901 (32), from August 1909 to February 1948 and that are deposited in the Helminthological Collection of the Oswaldo Cruz Institute were analyzed. The studied samples were represented by the cysticercus of the cestode Taenia pisiformis (Bloch, 1780) and by the nematodes Passalurus ambiguus (Rudolphi, 1819), Vianella fariasi (Travassos, 1915), Longistriata perfida Travassos, 1943, Trichostrongylus retortaeformis (Zeder, 1800). The scope of the present investigation is to survey the parasites infecting these hosts, commonly used as laboratory animal models in scientific research and supply figurative data on the helminths in order to provide their easy identification, since the presence of autochthonous parasite burdens, if undetected or misinterpreted, can alter the final results of experimental assays, mainly those related to immunological approaches, when cross-reactions can occur.

O presente trabalho fornece dados históricos básicos sobre o primeiro acervo particular de helmintos a ser incorporado a uma coleção helmintológica institucional brasileira. As amostras são representadas por nematóides, trematódeos digenéticos e acantocéfalos parasitos de hospedeiros vertebrados e que são agora catalogados.

This paper deals with data on the historical background of the first private helminth survey incorporated to an institutional helminthological collection in Brazil. The samples are represented by nematodes, digenetic trematodes and acanthocephalans recovered from vertebrate hosts, that are included in a check list.

An electronic database was developed for the proper and easy access to the samples deposited in the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC) considering its great biodiversity and the permanent demands for scientific support from Brazilian and foreign research institutions, on what concerns to the loan and inclusion of either type or voucher specimens in the CHIOC, that is the largest helminth collection in South America.

Data on nematodes of the genus Pelecitus Railliet & Henry, 1910, namely P. fulicaeatrae (Diesing, 1851) López-Neyra, 1956, P. anhingae Vuylsteke, 1957, P. tubercauda Vanderburgh, Anderson & Stock, 1984, P. vuylstekae (Molin, 1860) Bartlett & Greiner, 1986, P. tercostatus (Molin, 1860) Railliet & Henry, 1910, P. helicinus (Molin, 1860) Railliet & Henry, 1910, P. circularis (Molin, 1860) Railliet & Henry, 1910 and Pelecitus sp., are presented, with basis on 29 nematode samples recovered from Brazilian birds representing 13 families and 19 species that were captured between 1934-1951 in the southeastern and central regions; parasites were formerly deposited as unidentified material in the Helminthological Collection of the Oswaldo Cruz Institute.

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.

Worm burdens were evaluated and compared in two groups of the guinea pig, Cavia poreellus (Linnaeus, 1758): animals of the first group were conventionally maintained in an institutional animal house and those of the second group were openly kept in pet shops in Brazil. Animals from both sources were infected only with the nematode Paraspidodera uncinata (Rudolphi, 1819) Travassos, 1914 (10% of prevalence in guinea pigs from lhe institutional facility and 40% in those animals from the pet shop). Other helminth samples recovered from Brazilian guinea pigs during 52 years and that are deposited in the Helminthological Collection of the Oswaldo Cruz Institute (CHIOC) were also analyzed. Paraspidodera uncinata and the cestode Monoecocestus parcitesticulatus Rêgo, 1960 were identified in these samples.

Syphacia muris worm burdens were evaluated in the rat Rattus norvegicus of the strains Wistar (outbred), Low/M and AM/2/Torr (inbred), maintained conventionally in institutional animal houses in Brazil. Morphometrics and illustration data for S. muris recovered from Brazilian laboratory rats are provided for the first time since its proposition in 1935.

Nematodes studied herein and identified as Parabronema pecariae were collected in 1936 in the States of Rio de Janeiro and Pará and in 1940 in the State of Mato Grosso do Sul, Brazil. This species was proposed, with basis on female specimens that had been described earlier as Parabronema sp. Although the presence of males of P. pecariae was previously reported in Brazil, their description was not provided. The present paper deals with the first complete morphometric data on male specimens of P. pecariae recovered from peccaries (Pecari tajacu and Tayassu pecari).
