Seroprevalence survey for Salmonella Abortusovis infection in Swiss sheep flocks

Between 1976 and 2003, no infections with Salmonella Abortusovis had been officially recorded in Switzerland. Since then, however, several sheep flocks were infected and suffered massive fetal losses suggesting a re-emergence of the disease. Therefore, the aim of this study was to assess the epidemiological situation of S. Abortusovis infection in sheep in this country. A representative serum sample collected in 2007 in the context of certifying Brucella freedom included sera from 578 flocks with a total of 8426 sheep from all regions in Switzerland and the Principality of Liechtenstein. Sera were tested by ELISA for the presence of antibodies specific for S. Abortusovis. The cantonal seroprevalence was estimated at the sheep as well as the flock-level by taking into account (a) all flocks with one or more seropositive sheep (Flock 1+) and (b) only the flocks with two or more seropositive sheep (Flock 2+). Flocks with seropositive sheep were found throughout the country with an overall sheep-level prevalence of 1.7%. At the flock-level, overall prevalences of 16.3% and 5.0% were found for Flock 1+ and Flock 2+ definitions, respectively. Significant sheep-level clusters were located in the cantons of Bern, the Valais and Graubunden, while significant flock-level clusters (Flock 1+ and Flock 2+) were located in the canton of Graubunden only. Our results indicate that exposure of Swiss sheep flocks to S. Abortusovis is wide-spread.

Fracture risk and zoledronic acid therapy in men with osteoporosis

Fractures in men are a major health issue, and data on the antifracture efficacy of therapies for osteoporosis in men are limited. We studied the effect of zoledronic acid on fracture risk among men with osteoporosis.

Prevalence of vitamin B12 depletion and deficiency in Liechtenstein

OBJECTIVE: Data about vitamin B12 (B12) deficiency in the general population are scarce. The present study was performed to determine the prevalence of B12 deficiency in the general population of the Principality of Liechtenstein, as well as to identify sub-populations potentially at high risk. DESIGN: Retrospective study. SETTING: Ambulatory setting, population of the Principality of Liechtenstein. SUBJECTS: Seven thousand four hundred and twenty-four patients seeking medical attention whose serum samples were referred for routine work-up in an ambulatory setting were consecutively enrolled. Serum total B12 was determined in all patients in this cohort. In addition, for a subgroup of 1328 patients, serum holotranscobalamin was also measured. Prevalence of B12 deficiency was calculated. Further, multivariate logistical regression models were applied to identify covariates independently associated with B12 deficiency and depletion. RESULTS: Nearly 8 % of the general population was suffering from either B12 depletion or deficiency. The ratio between B12 depletion and deficiency was 2:1 for all age ranges. Pathological changes were detected predominantly in older people. Female gender was a significant predictor of B12 depletion. In the cohort, nearly 40 % exhibited either depletion or deficiency of B12. CONCLUSIONS: B12 depletion and deficiency are common in Liechtenstein, a Central European country. The measurement of biochemical markers represents a cost-efficient and valid assessment of the B12 state. When a deficiency of B12 is diagnosed at an early stage, many cases can be treated or prevented, with beneficial effects on individual outcomes and subsequent potential reductions in health-care costs.

Surveillance of bovine tuberculosis and risk estimation of a future reservoir formation in wildlife in Switzerland and Liechtenstein.

Bovine tuberculosis (bTB) caused by Mycobacterium bovis or M. caprae has recently (re-) emerged in livestock and wildlife in all countries bordering Switzerland (CH) and the Principality of Liechtenstein (FL). Comprehensive data for Swiss and Liechtenstein wildlife are not available so far, although two native species, wild boar (Sus scrofa) and red deer (Cervus elaphus elaphus), act as bTB reservoirs elsewhere in continental Europe. Our aims were (1) to assess the occurrence of bTB in these wild ungulates in CH/FL and to reinforce scanning surveillance in all wild mammals; (2) to evaluate the risk of a future bTB reservoir formation in wild boar and red deer in CH/FL. Tissue samples collected from 2009 to 2011 from 434 hunted red deer and wild boar and from eight diseased ungulates with tuberculosis-like lesions were tested by direct real-time PCR and culture to detect mycobacteria of the Mycobacterium tuberculosis complex (MTBC). Identification of suspicious colonies was attempted by real-time PCR, genotyping and spoligotyping. Information on risk factors for bTB maintenance within wildlife populations was retrieved from the literature and the situation regarding identified factors was assessed for our study areas. Mycobacteria of the MTBC were detected in six out of 165 wild boar (3.6%; 95% CI: 1.4-7.8) but none of the 269 red deer (0%; 0-1.4). M. microti was identified in two MTBC-positive wild boar, while species identification remained unsuccessful in four cases. Main risk factors for bTB maintenance worldwide, including different causes of aggregation often resulting from intensive wildlife management, are largely absent in CH and FL. In conclusion, M. bovis and M. caprae were not detected but we report for the first time MTBC mycobacteria in Swiss wild boar. Present conditions seem unfavorable for a reservoir emergence, nevertheless increasing population numbers of wild ungulates and offal consumption may represent a risk.

ll "Pasquillus extaticus" di Celio Secondo Curione: eresia, censura, tradizione a stampa e manoscritta del testo

The essay examines the print and manuscript traditions of the "Pasquillus extaticus" by Celio Secondo Curione with a particular focus on their relation with censorship. At first, the essay investigates into the redactional evolution and into the editorial history of the dialogue and of its vernacular versions, e.g. the relation between some editions of the "Pasquillus extaticus" and of the "Pasquino in estasi" (which appeared anonymously and without typographical information) and the provisions of political and ecclesiastical censorship in the 16th century. Finally, analysing the manuscript tradition, the essay discusses Carlos Gilly’s identification of «Coelii Secundi Pasquillus, emendatus impress[us]», registered in the inventory of the private library of the Basel typographer Johannes Oporinus, with the copy preserved at the Herzog August Bibibliothek Wolfenbüttel [hab: p 1811. 8º Helmst. (1)]). The author refutes Gilly’s hypothetical attribution to Curione’s handwriting of the many marginalia present in this copy.

Das Repertorium Academicum Germanicum (RAG). Ein digitales Forschungsvorhaben zur Geschichte der Gelehrten des alten Reiches (1250-1550)

This article aims at presenting an already existing research project. The Repertorium Academicum Germanicum (RAG) is supposed to be a "Who’s who" of the graduated and noble scholars of the late medieval Empire. It is designed to record biographical and social data of graduated theologians, jurists, physicians and Masters of Art as well as data of nobles from universities between 1250 and 1550. Furthermore, the project focuses on their examinations, networks, fields of activity in ecclesiastical and secular offices as well as their achievements and legacies (books, treatises, tombs etc). Right now, over 49.000 prosopographic entries are stored in the RAG database, partly available online (www.rag-online.org) and combined with digital maps (infographics), which already provide a basis for research in academic mobility determined by the top scholars of the time. In a next step, it should be possible to draw conclusions not only about personnel and knowledge transfer from university to society, its effects on political systems, daily life, the emergence of new occupational groups and professions, but also about cultural exchange within Europe.

The Role of the European Imperial Powers throughout the Armenian Schism in the 1870s

The Bull "Reversurus" (1867) and its dogmatic legitimization at the First Vatican Council in 1870 caused not only ecclesiastical controversy and Schism in the Armenian Catholic Church, but it had also wide political consequences for the Armenian Catholics in the Ottoman Empire. The conflict originally between the Armenian Catholics and Rome attracted very soon the attention of the European imperial Powers. France, the British Empire, the German Empire, Austria-Hungary and Russia were the main political powers who were involved in the Armenian affair. A full picture of the role of all these powers for the course of the Armenian Schism is missing. Mostly the role of France is foregrounded in the printed sources, as the main power, which supported the papacy to win during the Armenian affair. The role and the motives of the other imperial powers is almost missing. This article will try to describe as completely as possible the historical and political background, which brought to the escalation of the Armenian conflict beyond the national frontiers and led to number of conflicts at the international and transnational level. It will be shown that the imperial policy in Europe in the 19th century have played an enormous role throughout the Armenian Schism. It will be explained that several historical circumstances in Europe, especially the relation of the European imperial powers to each other as well as their expectations from the Ottoman Empire and its Armenian subjects were decisive for the duration and conclusion of the Armenian Schism.
