Intermediate and definitive hosts of Schistosoma mansoni in Corrientes province, Argentina

Corrientes province is located in the humid subtropical region of Argentina northeast on the left riverbank of Paraná River in the border with the South of Brazil. This is a region without schistosomiasis but planorbid and rodents that would serve as host of the life cycle of Schistosoma mansoni inhabit here. The objective of this work is to know the role of rodent as definitive host of schistosomiasis. Biomphalaria tenagophila (4 to 8 mm Ø) from Maloyas, exposed each to 10 miracidia of SJ2 strain of S. mansoni natives from Brazil were susceptible (5%). The degree of compatibility was Class II of Frandsen. Five wild rodents captured in the same ecological niche were exposed transcutaneously to infection with 40 cercariae for animal: two Olygoryzomys flavescens, two Holochilus braziliensis, and one Scapteromys tuncidus. Only one H. braziliensis eliminated eggs in feces. Prepatent period was of 83 days. With these feces, two of six (33.3%) B. tenagophila from Maloyas were infected with miracidium. It was demonstrated, in an area free of schistosomiasis, that life cycle S. mansoni is closed with planorbid and rodents that live in the same ecological niche.

Long-term outcomes of school-based treatment for control of urinary schistosomiasis: a review of experience in Coast Province, Kenya

Urinary schistosomiasis remains a significant burden for Africa and the Middle East. The success of population-based control programs will depend on their impact, over many years, on Schistosoma haematobium reinfection and associated disease. In a multi-year (1984-1992) control program in Kenya, we examined risk for S. haematobium reinfection and late disease during and after annual school-based treatment. In this setting, long-term risk of new infection was independently associated with location, age, hematuria, and incomplete treatment, but not with sex or frequency of water contact. Thus, very local environmental features and age-related factors played an important role in S. haematobium transmission, such that population-based control programs should optimally tailor their efforts to local conditions on a village-by-village basis. In 2001-2002, the late benefits of earlier participation in school-based antischistosomal therapy were estimated in a cohort of formerly-treated adult residents compared to never-treated adults from the same villages. Among age-matched subjects, current infection prevalence was lower among those who had received remote therapy. In addition, prevalence of bladder abnormality was lower in the treated group, who were free of severe bladder disease. Treatment of affected adults resulted in rapid resolution of infection and any detectable bladder abnormalities. We conclude that continued treatment into adulthood, as well as efforts at long-term prevention of infection (transmission control) are necessary to achieve optimal morbidity control in affected communities.

New record and larval habitats of Culex eduardoi (Diptera: Culicidae) in an irrigated area of Patagonia, Chubut Province, Argentina

The object of the present work was to identify the larval habitats of Culex eduardoi and to determine the microenvironmental conditions related to their presence in different artificial freshwater environments (temporary, semi-permanent, irrigation ditches, and drainage ditches) in tillable areas of Chubut Province, Argentina. This report represents the first record of Cx. eduardoi from this Province and extends its range to latitude 45°S. Immature stages of Cx. eduardoi were found in 8 out of 109 (7.3 %) freshwater habitats and were significantly more prevalent in semi-permanent water bodies. Positive sites had significantly larger surface areas and more vegetation cover than negative sites.

L'Écriture à rebours. Le Roman de Méliadus du XIIIe au XVIIIe siècle

Continuation elleptique du "Tristan en prose", qui s'inscrit dans l'interstice séparant la naissance de Tristan du remariage de Méliadus avec la fille du roi Hoël, le "Roman de Meliadus" (1235-1240) est une oeuvre demeurée ouverte, de par son inachèvement et de par le dialogue constant qu'il instaure avec les autres romans arthuriens. S'il revendique sa filiation et assume son statut de récit puîné, les réminiscences qu'il exhibe masquent aussi les gauchissements, les infléchissements qui lui permettent de faire du neuf avec du vieux. C'est ce jeu - aux deux sens du terme - que Barbara Wahlen étudie et montre à voir, non seulement dans le "Roman de Meliadus" proprement dit, mais également dans trois de ses relectures, qui actualisent et renouvellent la signification du roman en profondeur. La première est une continuation de la toute fin du XIIIe ou du début du XIVe siècle qui est aujourd'hui conservée par le seul manuscrit Ferrell 5. La deuxième actualisation retenue est celle qu'offre "Meliadus de Leonnoys", l'imprimé publié en 1528 par Galliot du Pré, fruit d'un minutieux travail de découpage et de remontage. La dernière enfin est l'extrait paru en 1776 dans la "Bibliothèque Universelle des Romans".

Parasites in rodent coprolites from the historical archaeological site Alero Mazquiarán, Chubut Province, Argentina

The aim of this study was to examine the parasitic remains that were found in rodent coprolites collected from the archaeological site Alero Mazquiarán (Chubut Province, 45º44'15"S, 70°25'9"W), which is assigned to the interface of the Araucanian and Tehuelche cultures, dated at 212 ± 35 years B.P. The faecal material from two unidentified rodent species (X-10 and X-11) was collected from one human pelvic cavity found in a multiple burial. The faecal samples were processed and examined using paleoparasitological procedures. The X-10 coprolites were positive for eggs of Monoecocestus sp. (Cestoda: Anoplocephalidae) and the X-11 faeces were positive for Pterygodermatites sp. (Nematoda: Rictulariidae), Trichosomoides sp. (Nematoda: Trichosomoididae) and Monoecocestus sp. In this study, we discuss parasitic life cycles, the zoonotic importance of parasites and the behaviour of the aboriginal people.

M-Library in an m-University : changing Models in the Open University of Catalonia

The general perspective of M-technologies and M-Services at the Spanish universities is not still in a very high level when we are ending the first decade of the 21st century. Some Universities and some of their libraries are starting to try out with M-technologies, but are still far from a model of massive exploitation, less than in some other countries. A deep study is needed to know the main reasons, study that we will not do in this paper. This general perspective does not mean that there are no significant initiatives which start to trust in M-technologies from Universities and their libraries. Models based in M-technologies make more sense than ever in open universities and in open libraries. That's the reason why the UOC's Library began in late 90s its first experiences in the M-Technologies and M-Libraries developments. In 1999 the appropriate technology offered the opportunity to carry out the first pilot test with SMS, and then applying the WAP technology. At those moments we managed to link-up mobile phones to the OPAC through a WAP system that allowed searching the catalogue by categories and finding the final location of a document, offering also the address of the library in which the user could loan it. Since then, UOC (and its library) directs its efforts towards adapting the offer of services to all sorts of M-devices used by end users. Left the WAP technology, nowadays the library is experimenting with some new devices like e-books, and some new services to get more feedback through the OPAC and metalibrary search products. We propose the case of Open University of Catalonia, in two levels: M-services applied in the library and M-technologies applied in some other university services and resources.

The deployment of an e-book consultation and loan service : the experience of the Open University of Catalonia Library

La Biblioteca de la UOC (UOC Library) ha ofert durant tres mesos (octubre-desembre 09), en fase de prova pilot, un servei de consulta i préstec de lectors de llibres electrònics (e-readers). Aquest nou desplegament s'ha desenvolupat en consonància amb l'aposta general de la Universitat en innovació en tecnologies aplicades a l'educació, i la voluntat de potenciar les col·leccions de llibres electrònics i l'ús dels dispositius de lectura de llibres electrònics com una extensió més de la tecnologia del Campus 5.0, en el suport a l'aprenentatge dels seus estudiants durant la seva formació a la Universitat. Aquest treball presenta en detall les especificacions de la prova pilot, a més de contenir una anàlisi i avaluació dels resultats obtinguts: punts forts i punts febles, relació dels aspectes a millorar i modificar, de cara a la consolidació final del servei.
