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.

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.

The tegument of the adult form of Prosorhynchoides arcuatus (Linton, 1900) (Trematoda, Bucephalidae) from the intestine of Pomatomus saltator (L.) from the Atlantic coast of the State of Rio de Janeiro, Brazil was studied by transmission electron microscopy. The tegument consists of two layers: an external, constituted by a syncytium, containing spines, unicilliated papillae, inclusion bodies and mitochondria and an internal, consisting of a muscular layer and mononucleated tegumental cells.

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.

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.

L'objectiu d'aquest estudi és comparar la propaganda dels totalitarismes soviètic i nazi amb les novel•les d'Un Món Feliç (Aldous Huxley) i 1984 (George Orwell). D'aquesta manera, demostrem que la manipulació i el control dels sistemes descrits en cada llibre són equiparables a la història real.

The black flies of the genus Inaequalium present a Neotropical distribution, with Panama at the northern limit, and the Argentinian pampas at the southern, but do not occur in the Central Amazon. This study offers a cladistic analysis establishing a hypothesis of relationships between the species of Inaequalium. A total of 37 characters have been considered in order to establish the hypothetic phylogenetic relationships. Cerqueirellum (Py-Daniel, 1983) was considered as outgroup. Data were analyzed using Henning 86 version 1.5. Wich the ie* command and implicit enumeration a unique possible cladogram was obtained in Inaequalium with 52 steps, and a CI of 0.76 and RI of 0.81. Two well-defined clades was obtained in the resulting cladogram, the "botulibranchium" species-group, includes I. travassosi, I. souzalopesi, I. botulibranchium and I. petropoliense, and the "inaequale" species-group, includes I. rappae, I. nahimi, I. inaequale, I. leopoldense, I. subnigrum, I. diversibranchium, I. mariavulcanoae, I. nogueirai, I. beaupertuyi, I. clavibranchium and I. subclavibranchium.

From April 1984 to March 1985, a Trypanosoma lewisi prevalence of 21.7% was found in 429 Rattus norvegicus trapped in Belo Horizonte, State of Minas Gerais, Brazil. The infection rates were higher in male and young rats and could be attributed to ecological and behavioral factors. T. lewisi was observed in rats measuring between 60 and 250 mm. Data about monthly T. lewisi infections throughout the year are presented for the first time in Brazil, with the highest prevalences observed in the warm-rainy season (October to March).

This Final Report is the culmination of a two-stage process aimed at fulfilling the request of the previous Minister for Health and Children (Mary Harney) in relation to the practice of symphysiotomy in Ireland. The first phase was an independent academic research report. The second phase involved consultation with relevant stakeholders to provide comment on the report. Download the report here Â
