A study to demonstrate freedom of Trichinella spp. in domestic pigs in Switzerland

Trichinellosis is a food-borne zoonotic disease caused by the nematode Trichinella spp. Many omnivorous and carnivorous animal species can act as host for this parasite, including domestic pigs. To protect public health, it should be ensured that pork should not contain infective Trichinella larvae. Surveillance for Trichinella spp. can be done using direct (larval detection) and indirect (antibody detection) diagnostic techniques. The aim of this study was to demonstrate the absence of infection in Swiss domestic pigs. An ELISA was used as the initial screening test, and sera reacting in ELISA were further investigated using both a Western blot for serology and an artificial digestion test with 20 g of diaphragm tissue for larval detection. A total of 7412 adult pigs, 9973 finishing pigs and 2779 free-ranging pigs were tested. Samples from 17 (0.23%) adult pigs, 16 (0.16%) finishing pigs and nine (0.32%) free-ranging pigs were ELISA-positive, but all of these sera were subsequently negative by Western blot and by the artificial digestion method. Based on these findings, an absence of Trichinella infections in adult pigs (target prevalence 0.04%) and finishing pigs (target prevalence 0.03%) can be concluded. The results also demonstrated that the prevalence of Trichinella infections does not exceed 0.11% in free-ranging pigs, the group with the highest risk of exposure.

Cultural and Educational Society of Muslims "Narodna Uzdanica" /"National Hope"/ 1923-1941

Ibrahim Kemura. The Muslim Cultural-Educational Society Narodna uzdanica from 1923/4 to 1941 One of the features of the cultural history of the Bosniacs between the two world wars (1918-1941) was a cultural and educational society named Narodna uzdanica, which was a significant institutional and cultural-intellectual centre of the Bosniac people in Bosnia and Herzegovina. Narodna uzdanica expressed the aspirations and needs of the Bosniac citizens who were its main support and axis and was aimed at fulfilling their interests. This was reflected in an ideological-cultural orientation towards the West and the adoption of positive western achievements while at the same time stressing its Slavic origins and individuality, the education of young people and the formation of a European-type civic intelligentsia, adaptation to life in capitalist society, the development of modern trade and crafts, the emancipation of women, and cultural education based on European values. Thus conceived, the programme enjoyed the support of a wider circle of members, the reading public and the cultural consumers of those particular elements such as education and economic prosperity which it sought to achieve. The political involvement of Narodna uzdanica and its use as a platform for the leading Bosniac political party Jugoslovenska muslimanska organizacija (JMO - Yugoslav Muslim Organisation) which had founded the society, played a significant role in the socio-political life and development of Bosniacs. The opposition to the ruling regime, often expressed through close cooperation with similar Croat organisations and through the pro-Croat attitude of some of the society's leading figures, offered both the regime and Narodna uzdanica's political adversaries grounds for describing it as separatist and Croat and served as a pretext for repressive measures to hinder its normal operations. This research proved these accusations to be groundless, showing that the pro-Croat orientation was primarily political and cultural and that throughout its existence Narodna uzdanica was active in the cultural and educational renaissance of Bosniacs, helping to strengthen their national identity.

Kunst am Bau. Die Scuole centrali antincendi in Rom-Capannelle (1941)

Erstmals wird der figürliche und gemalte Dekor der mitten im Zweiten Weltkrieg eingeweihten staatlichen zentralen Ausbildungsstätte für Feuerwehrleute in Rom bekannt gemacht. Dank des Entgegenkommens der Leitung dieser Schulen (heutiger Name: Scuola per la formazione di base dei vigili del fuoco) können in neuen Aufnahmen Mosaiken, Wandmalereien, Reliefs und Skulpturen dokumentiert und mit Fotografien aus dem dortigen Historischen Archiv ergänzt werden. Wie zu erwarten, stellt die sportliche Ertüchtigung der jungen Feuerwehrmänner ein Hauptthema der ›Kunst am Bau‹ dar. Es ist wichtig festzuhalten, dass keineswegs ein militärischer Aspekt im Vordergrund des Dekors steht. Der Artikel versteht sich als Beitrag zur Erweiterung unserer Kenntnisse von Dekorelementen an staatlichen Einrichtungen des Faschismus.
