Project Details:
Ziel der Studie soll die Evaluierung der Ausbreitung von Ophidiomyces in der Schlangenpopulation in Deutschland sein. Durch Einbeziehung klinisch gesunder und erkrankter Schlangen soll eine Aussage bezüglich der Prävalenz getroffen und weitere Erkenntnisse über die Pathogenität und Auswirkungen sowohl auf das Einzeltier als auch die Gesamtpopulation sollen gesammelt werden.

Project Details:
Interactions between humans and wild animals in teh urban environment take place in many ways, indirectly and directly, rationally and emotionally. The discourse will involve various interest groups using variable discussion formats with online participation and accompanying data collection. Structured debates, including scientific findings and expertise, are intended to formulate theses on how to deal with animals in the human environment and create respective recommendations.

Project Details:
Uniferon is an injectable 20% iron dextran for prevention and treatment of anaemia in swine. 200 mg iron is routinely administered to piglets within the first days of life to prevent development of anaemia. Empirical observations show, that iron deficiency can develop within the first four weeks of life despite this early preventive measure due to the high growth rates of modern cross-bred pigs. While the product Uniferon can be used in flexible volumes, so that an adaptation of the iron amount administered is possible, the competitor product Forceris can only be used in a fixed dosage of 1.5 ml containing 200 mg iron -gleptoferron in combination with 45 mg toltrazuril as a coccidiostaticum. The advantage of this combinatory product to address two different diseases by one single shot is counteracted by the lack of adjustment of the necessary amount of iron to prevent anaemia as long as possible. Different iron treatments in suckling piglets should be evaluated to review the traditional recommendations for iron applications and adjust them according to the higher genetic potential for growth in modern pig breeds if necessary.

Project Details:
Pig production has grown dramatically worldwide over the last 20 years, leading to increased herd sizes
with weekly production cycles of piglets. In the meantime, the dynamics of infections with swine influenza A
viruses (swIAV) have changed, from epizootic acute respiratory
outbreaks to a self-sustaining infected status of affected herds. Moreover, the genetic and antigenic
diversity of swIAVs in European pig populations has dramatically increased in recent years. Thus, novel
reassortants and antigenic variants have emerged regionally, that can escape control strategies based on
vaccines licensed for use in Europe. The self-sustaining forms of swine influenza (SI) in large holdings
adversely affect animal health and welfare, and prompts the excessive use of antibiotics when swIAV is
associated with other respiratory pathogens in the porcine respiratory disease complex (PRDC), resulting in
severe economic losses. There is an urgent need to increase knowledge of within-herd virus dynamics and
evolution in order to design intervention and prevention measures to limit swIAV persistence in intensive
herds and counteract continuous production losses and emergence of new swIAVs.The objectives of the
research project PIGIE are:
- to define the epidemiological and economic factors that drive the prevalence and dynamics of swIAV in
large pig herds,
- to evaluate the impact that swIAV enzootic infections have on animal welfare, production parameters and
economic productivity,
- to study the genetic and antigenic diversity of swIAV in Europe,
- to identify the host-pathogen factors that would foster swIAV evolution,
- to provide a better understanding of long-lasting and protective immunological memory responses
developed in the infected hosts,
- to identify mitigation points in continuously infected herds,
- to implement and evaluate control strategies that would help to counter sustained infections in closed
intensive herds.
