Sobre a validade das espécies pertencentes ao gênero Prosthogonimus Luehe, 1899, da coleção Helmintológica do Instituto Oswaldo Cruz

Os autores estudam todo o material brasileiro pertencente ao gênero Prosthogonimus Luehe, 1899, depositado na Coleção Helmintológica do Instituto Oswaldo Cruz, determinado e sem determinação, e concluem que apesar de apresentar grande variação em seus caracteres, pertence à uma única espécie Prosthogonimus ovalus (Rudolphi, 1803). Essa variação já havia sido observada anteriormente por Travassos (1922-1928) e confirmada experimentalmente por Boddeke (1960). São apresentadas 49 figuras e 5 quadros com as medidas correspondentes, mostrando as variações encontradas.

Vinte espécies do gênero Diplotriaena Henry & Ozoux, 1909 que ocorrem no Brasil, foram estudadas. A taxonomia desse grupo de nematódeos parasitos de aves é baseada na forma e tamanho dos tridentes e espículos. Para todas as espécies forma registradas suas dimensões, hospedeiros e distribuição regional, através de tabelas comparativas. Comentários a respeito de algumas espécies foram feitos, de modo a fornecer dados adicionais. É também apersentada uma chave para a determinação das espécies.

Lampas y el espíritu de la naturaleza: estudio de la controversia entre Henry More y Robert Hooke

“Lampas y el Espíritu de la Naturaleza” estudia la controvèrsia entre Henry More i Robert Hooke a propòsit de la filosofia mecànica de la naturalesa en el context del pensament filosòfic i científic del segle XVII a Anglaterra, una controvèrsia que malgrat que es pugui considerar obsoleta en la seva forma no ho és en el seu fons, ja que tant les qüestions plantejades per More com les observacions de Hooke són pertinents i no són lluny, mutatis mutandis, de determinats plantejaments del nostre present.

On Thelazia anolabiata (Molin, 1860) Railliet & Henry, 1910 (Nematoda, Thelazioidea): a new host record and systematic considerations

Thelazia anolabiata (Molin, 1860) Raillet & Henry, 1910, parasite of eyes of birds, is reported in s new host, Ortalis canicolis pantanalensis Cher & Reich from Salobra, Mato Grosso do Sul State; T. digitata Travassos, 1918 and T. lutzi Travassos, 1918 are considered its synonyms.

Nematode parasites of Brazilian psittacid birds, with emphasis on the genus Pelecitus railliet & Henry, 1910

In the present paper, some species of nematodes from Brazilian parrots are studied: Aproctapyrrhurae. Ascaridia hermaphrodita, A. sergiomeirai, Pelecitus circularis and P. helicinus. Single female specimens of Pelecitus sp. and Thelazia sp. are presented. The male of P. circularis is fully illustrated, for the first time, since 1884. Ascaridia sergiomeirai is also restudied 59 years after proposition. New host records are estabilished. Remarks on other species of nematodes occuring in psittacid birds are included.

A new species of Phyllodistomum Braun, 1899 (Digenea: Gorgoderidae) from Rhamdia quelen (Quoy & Gaimard, 1824) (Siluriformes: Pimelodidae)

Phyllodistomum rhamdiae n. sp. is described based on specimens collected from the urinary bladder of freshwater catfishes, Rhmdia quelen, caught from the Guandu river, outskirts of Rio de Janeiro, State of Rio de Janeiro, Brazil. The new species is characterized by its sucker width ratio equal to 1:1, by the large size of the gonads and their spatial arrangement.

Biomphalaria subprona (Martens, 1899) (Gastropoda: Planorbidae)

A description is given of the shell, head-foot, pulmonary wall, reproductive system and radula of Biomphalaria subprona (Martens, 1899). A diagnosis between it and two other congeneric species under 10 mm in shell diameter occurring in Middle America (Biomphalaria helophila and B. schrammi) is presented.

Une pensée économique russe?: présentation, traduction et annotation de l'article "Science Economique" (1899) de Mikhail Ivanovich Tugan-Baranovskij

L'économiste russe Tugan-Baranovskij (1865-1919) a publié en 1899 une notice sur le développement de la « science économique russe » pour la première encyclopédie universelle russe, le Brockhaus-Efron. Sous la forme d'un catalogue chronologique des économistes russes et de leurs ouvrages tout au long du XIXe siècle, le récit de Tugan-Baranovskij représente une des premières tentatives d'écrire une histoire de la pensée économique russe. L'intérêt du texte se manifeste lorsqu'on s'interroge sur l'existence d'une telle science « nationale » de l'économie politique. Nous présentons ici en traduction française ce récit jamais encore traduit du russe, et nous l'accompagnons de notes sur les auteurs et les ouvrages qui y sont signalés.

Presence of Panstrongylus rufotuberculatus (Champion, 1899) (Hemiptera: Reduviidae: Triatominae) in Argentina

Panstrongylus rufotuberculatus is reported for the first time in Argentina. Four adults were attracted by the light of human dwellings in Calilegua National Park, Jujuy, at 1150 masl within the subtropical humid forest. The individuals were similar to those described in the literature. The epidemiological significance of this species is very low in the area, although deforestation might increase its role in the transmission of Trypanosoma cruzi.

Pelecitus helicinus Railliet & Henry, 1910 (Filarioidea, Dirofilariinae) and Other Nematode Parasites of Brazilian Birds

We report Pelecitus helicinus Railliet & Henry, 1910 from 13 species of birds of 2 orders and 7 families, collected from the states of São Paulo and Mato Grosso, Brazil. All 13 constitute new host records for this nematode. In addition, we report the first record of Aprocta golvani Diaz-Ungria, 1963 from Brazil and Monasa nigrifrons (Bucconidae), as well as a number of other nematode records from Neotropical birds.

Infectious disease among enslaved African Americans at Eaton's Estate, Warren County, North Carolina, ca. 1830-1850

The skeletal remains of 17 people buried in the Eaton Ferry Cemetery in northern North Carolina provide a means of examining health and infectious disease experience in the XIX century South. The cemetery appears to contain the remains of African Americans enslaved on the Eaton family estate from approximately 1830-1850, and thus offers a window into the biological impacts of North American slavery in the years preceding the Civil War. The sample includes the remains of six infants, one child, and one young and nine mature adults (five men, four women, and one unknown). Skeletal indices used to characterize health and disease in the Eaton Ferry sample include dental caries, antemortem tooth loss, enamel hypoplasia, porotic hyperostosis, periosteal lesions, lytic lesions, and stature. These indicators reveal a cumulative picture of compromised health, including high rates of dental disease, childhood growth disruption, and infectious disease. Specific diseases identified in the sample include tuberculosis and congenital syphilis. Findings support previous research on the health impacts of slavery, which has shown that infants and children were the most negatively impacted segment of the enslaved African American population.
