Notas de ixodologia: VII - Otocentor nitens Neuman, 1897) versus Anocentor columbianus Schulze, 1937 e comentários sôbre a rápida disseminação desse ixodideo no Brasil (Acari: Ixodidae)

Anocentor columbianus Schulze, 1937 is a synonym of Otocentor nitens (Neumann, 1897). Otocentor Cooley, 1938 becomes a synonym of Anocentor Schulze 1937. The correct name of the species is now Anocentor nitens (Neumann, 1897). In Brazil this species was first recorderd by ARAGÃO (in FLOCH and ABONNENC, 1945) in Belém do Pará and by FONSECA (1948) in Goyaz. New records from Minas Gerais and Matto Grosso are presented and a new host, the jaguar, Panthera onca, is added.

Contribuição para o conhecimento dos parasitos de peixes do litoral do Estado da Guanabara - parte II

No presente trabalho os autores criam uma nova espécie para o gênero Lecithochirium Luehe, 1901, ficando no 3º grupo de distribuição de Freitas & Gomes (1971), mais se aproximando de L. manteri Freitas & Gomes, 1971, distinguindo-se principalmente por possuir saco genital aberto, vesícula ejaculadora externa ausente, vesícula seminal trilobada e ovos maiores. Apresentam Promatomus saltatrix (L.) como novohospedador para Parahemiurus merus (Linton, 1910) Yamaguti, 1938 ressaltando as variações encontradas nas medidas. Para Acanthocollaritrema umbilicatum Trav., Freitas e Bührnheim, 1965, acusam a presença do gonotil, e por esta razão acham que provavelmente Acanthocollaritrematinae Trav., Freitas e bührnheim, 1965, deva pertencer à família Cryptogonimidae Ciurea, 1933. Referem ainda a presença de Bucephalopsis callicotyle Kohn, 1962, Microcotyle pomatomi Goto, 1899 (polistomata) e larvas de Trypanorhyncha Diesing, 1863 (Cestoda0, em Pomatomus saltatrix (L.).

Alguns Helmintos de peixes do litoral norte fluminense - II

De 62 autópsias realizadas empeixes, capturados no litoral de Macaé, Estado do Rio de Janeiro, os autores coletaram alguns exemplares de helmintos cujo estudo permitiu a descrição de 2 espécies novas: Cucullanus rougetae e Raphidascaris yamagutii; a redescrição de Pseudopecoelus elongatus (Yamaguti, 1938) em novo hospedeiro, as referências de Procamallanus macaensis Vicente e Santos, 1972, e Catarinatrema verrucosum Freitas & Santos, 1971 e a descrição de 2 larvas de nematódeos e 1 de cestódeo que não puderam ser determinadas até espécie. A excursão emque foram colecionados os helmintos acima relacionados foi realizada em janeiro de 1973 por um de nós (elias dos Santos) permitindo a continuação de trabalho anterior sobre helmintos de peixes marinhos daquele município fluminense.

About some trematodes parasites of Haemulon sciurus (Shaw, 1803)

From September, 1980 to August, 1981 forty specimens of Haemulon sciurus from "Praia da Ribeira, Ilha do Governador", Rio de Janeiro State, were examined for parasites. In this paper, parcial results concerning only the collected trematodes are reported: Diplomonorchis leiostomi Hopkins, 1941 (first record in Brazil and in a new host); Lasiotocus beauforti (Hopkins, 1941) Thomas, 1959 (new host record); Genolopa ampullacea Linton, 1910; Parahemiurus merus (Linton, 1910) Yamaguti, 1938 (new host record): Aponurus pyriformis (Linton, 1910) Overstreet, 1973 and Diplangus paxillus Linton, 1910. Figures, measurements and comments of each species are given.

Scanning electron microscopy of the male genitalia of Sarcophagidae (Diptera)

The male genitalia of nine species of Sarcophagidae (Diptera) - Goniophyto honsuensis Rohdendorf, 1962, Tricharaea brevicornis (Wiedemann, 1830), Chaetoravinia derelicta (Walker, 1852), Austrohartigia spinigena (Rondani, 1864), Chrysagria duodecimpunctata Townsend, 1935, Boettcheria bisetosa Parker, 1914, Lipoptilocnema lanei Townsend, 1934, L. crispina (Lopes, 1938) and Euboettcheria alvarengai Lopes & Tibana, 1982 - were examined by scanning electron microscope (SEM) and the main morphological features are descirbed.

Spirura delicata sp. n. (Spiruridae, Spirurinae) from Leontocebus mystax (Callithrichidae) and a check list of other Nematodes of some brazilian primates

Spirura delicata sp. n. from Leontocebus mystax (Six) is proposed and compared to S. guianensis (Ortlepp, 1924) Chitwood, 1938, S. michiganensis Sandground, 1935 and S. nayarani Mirza & Basir, 1938. Their differentiation is based mainly on the size and shape of spicules. Identification of nematode samples recovered from primates along 60 years and presently deposited in the Oswaldo Cruz Helmintological Collection is provided herein through a check list. Some of them are reported in new hsots and/or geographical regions.

Digenetic trematodes (Cryptogonimidae, Acanthostominae) parasites of the Caiman, Caiman crocodilus yacare (Reptilia, Crocodylia) from the Pantanal Mato-grossense, Brazil, with the description of a new species

Proctocaccum dorsale n. sp. is described and Caimanicola marajoara Freitas & Lent, 1938 is redescribed based on specimens collected from Caiman crocodilus yacare (Daudin) from the Pantanal Mato-grossense, State of Mato Grosso do Sul, Brasil. This report extends south ward the known geographic distribution of C. marajoara. It is the first record of the genus Proctocaccum in South America, and in the caiman. Proctocaccum dorsale n. sp. differs from the other eight species in the genus by the dorsal location of the anal openings, instead of being lateral or in the posterior extremity of the body.

Distribuição Geográfica e Dispersão Alti-latitudinal de Alguns Gêneros e Espécies da Tribo Triatomini Jeannel, 1919 (Hemiptera, Reduviidae, Triatominae)

Geographical Distribution and Alti-latitudinal Dispersion of Some Genera and Species of the Tribe Triatomini Jeannel, 1919 (Hemiptera, Reduviidae, Triatominae) - With the currently known distribution of genera and species of the tribe Triatomini Jeannel, 1919, maps and diagrams were prepared, showing the geographical area occupied by the species and their respective dispersion in grades of latitude and altitude. Two genera are not treated: Panstrongylus Berg, 1879, already published and Triatoma Laporte, 1832, that is being published partially in several articles. Genus Eratyrus Stal, 1859, has two species, while Dipetalogaster Usinger, 1939, Mepraia Mazza, Gajardo & Joerg, 1940, Paratriatoma Barber, 1938 and recently created genus Hermanlentia Jurberg & Galvão, 1997, have only one each. The study of these maps and diagrams permits a better knowledge about some ecological requirements of Chagas' disease vectors and detects gaps in the geographical distribution, where the species were not found but probably they could be prevalent

Fimbriaria fasciolaris and Cloacotaenia megalops (Eucestoda, Hymenolepididae), Cestodes from Brazilian Waterfowl

Two cestode species, Fimbriaria fasciolaris (Pallas, 1781) Frölich, 1802 Cloacotaenia megalops (Nitzsch in Creplin, 1829) Wolffhügel,1938 collected from Anas bahamensis Linné, 1758 and Amazonetta brasiliensis (Gmelin, 1758) in lagoons of the Maricá District, State of Rio de Janeiro, Brazil, are described. This is the first record of F. fasciolaris parasitizing A. bahamensis. The prevalence, intensity of infection, and mean intensity of infection for both species are given. Overdispersion distribution is reported for F. fasciolaris with 535 specimens collected in a single A. bahamensis. A key for the genera in the Fimbriariinae is presented. Anatomical features of F. fasciolaris and C. megalops are discussed.

Plesiophysa dolichomastix sp. n. (Gastropoda: Planorbidae)

A new species of planorbid mollusc, Plesiophysa dolichomastix (Greek dolichos = long, mastix = flagellum), collected from Lagoa da Pedra, municipality of Santa Rosa, state of Goiás, Brazil (15°01'S, 47°13'W) is described. It is indistinguishable by the shell characters from the five congeneric species described so far: P. striata (Orbigny, 1841), P. granulata ("Shuttleworth" Sowerby, 1873), P. guadeloupensis ("Fischer" Mazé, 1883), P. ornata (Haas, 1938) and P. hubendicki Richards & Ferguson, 1962. It differs from the anatomically studied species in the following characters: about 50 ovotestis diverticula, against 12 in granulata, 100 in ornata, unstated in hubendicki; and length of flagella - about as long as the penial complex -, against about 1/3 to 1/6 in the other three.

Plesiophysa guadeloupensis ("Fischer" Mazé, 1883)

A description is presented of the shell and anatomic characters of the planorbid mollusk Plesiophysa guadeloupensis ("Fischer" Mazé, 1883), based on topotypic specimens from a pond in Borricaud (Grande Terre, Guadeloupe). Comparison with previous descriptions of nominal species of Plesiophysa points to its identity with P. ornata (Haas, 1938), of which it is a senior synonym.

Sandflies (Diptera: Psychodidae: Phlebotominae) collected on the banks of the Velhas River in the state of Minas Gerais, Brazil

Leishmaniases are endemic to several Brazilian states, including Minas Gerais. As many cases of these diseases are diagnosed in Minas Gerais every year, this paper aimed to determine the diversity of the species of sandflies vector of leishmaniases, in Lassance and Corinto on the banks of the Velhas River. Over two years, 21,014 specimens of sandflies, belonging to 19 species were captured with light traps. Of these specimens, Nyssomyia neivai (Pinto 1926) (84.18%), Nyssomyia intermedia (Lutz & Neiva 1912) (13.41%), Evandromyia lenti(Mangabeira 1938) (0.99%) and Evandromyia sallesi (Galvão & Coutinho 1939) (0.48%) were the most represented. The former two species could be involved in the epidemiological chain of leishmaniasis in this region. No significant difference was found between the species compositions on the two river banks.

Historical review of clinical vaccine studies at Oswaldo Cruz Institute and Oswaldo Cruz Foundation - technological development issues

This paper presents, from the perspective of technological development and production, the results of an investigation examining 61 clinical studies with vaccines conducted in Brazil between 1938-2013, with the participation of the Oswaldo Cruz Institute (IOC) and the Oswaldo Cruz Foundation (Fiocruz). These studies have been identified and reviewed according to criteria, such as the kind of vaccine (viral, bacterial, parasitic), their rationale, design and methodological strategies. The results indicate that IOC and Fiocruz have accumulated along this time significant knowledge and experience for the performance of studies in all clinical phases and are prepared for the development of new vaccines products and processes. We recommend national policy strategies to overcome existing regulatory and financing constraints.
