Necrotic Enteritis (NE) caused by Clostridium perfringens (CP) in poultry is probably the most important bacterial disease in terms of economic implications. The disease is multi-factorial and is invariably associated with predisposing factors. The present study investigated the effect of a commercially available Lactobacillus-based probiotic (FM-B11) for the control of necrotic enteritis in broiler chickens. In experiment 1, one-day-of-hatch broiler chicks were randomly allocated to the following treatment groups: 1) Non-challenged (NC); 2) Challenged (C); 3) Challenged + probiotic (C+ FM-B11). Prior to placement, chicks in groups 2 and 3 received 0.25 mL of Salmonella typhimurium (ST) containing 105 cfu of viable cells by oral gavage. At 14, 15 and 16 days of age, all chicks in group 3 were treated with FM-B11 in the drinking water at a concentration of 106 cfu/ml. At 21d of age, all chicks in groups 2 and 3, were individually challenged with 5 × 104 sporulated oocysts of E. maxima by oral gavage. At 26d of age, all chicks in groups 2 and 3, were individually challenged with 108 cfu CP; body weight (BW) was recorded prior to challenge. The experiment was terminated at 29 days of age and the following parameters were evaluated: NE-associated mortality, CP lesion scores, CP concentrations in ileum, BW, and body weight gain (BWG). Chicks treated with FM-B11 had significantly (P < 0.05) higher body weight gain after challenge when compared to control challenge chickens. Total mortality was higher in the C group (48.8%) when compared to the C + FM-B11 (12.7%). Even though there was no significant (P > 0.05) difference in lesion score between C and C + FM-B11, group C + FM-B11 had significantly (P < 0.05) lower total number of cfu of CP recovered from the ileal mucosa and content samples when compared to group C. Experiment 2 was a unique and remarkable case report of a field outbreak of NE in a commercial broiler farm in Argentina. A reduction and control of the mortality associated with NE following 3 days of administration of FM-B11 was observed as compared with the control non treated house. These results imply that the commercially available Lactobacillus-based probiotic FM-B11 was able to reduce the severities of NE, as a secondary bacterial infection, in an experimental NE challenge model; as well as, in a commercial field outbreak of NE.

<p>While Italian art of the twentieth century is usually associated with either the avant-garde practices of Futurism or the classicism of Fascist visual culture, the Italian modernists' complex engagement with concepts of the ‘Baroque’ has yet to be explored. Through an extensive analysis of paintings, sculptures, publications, collecting practices, and exhibitions, my dissertation addresses this lacuna by investigating how the Baroque was discursively constructed and visually represented in Italian modernist artistic and cultural debates between 1880 and 1945. I study how artists and critics such as Umberto Boccioni, Giorgio De Chirico, Adolfo Wildt, Lucio Fontana, and Roberto Longhi championed or disparaged the Baroque in the context of heated debates over the import of Italy’s rich cultural heritage, its status in modern Europe, and the potential role of avant-garde art as a catalyst for national regeneration. In contrast to previous scholars I argue that the development of modern art in Italy was actively shaped by cultural perceptions about the Baroque. My dissertation therefore sheds new light on the role of style in the cultural politics of Italy, which in turn will transform our understanding of visual culture in modern Italy, and of twentieth-century representations of the Baroque in art, literature, and aesthetics.p>
