　　报告题目：About Antibiotic resistance, biomonitors and Pearl mussels in freshwater - some case studies on the analysis of freshwater quality in Germany

　　专家简介：

　　Thomas Berendonk received his phD at the Max-Planck-Institute in Ploen Germany and then spent four years as a post doc in the UK, at the Natural History Museum London, Imperial College, Centre for Population Biology and finally at the Department of Zoology in Oxford. He returned to Leipzig at a lectureship position and started 2009 at the TU Dresden as Professor and Director of the Institute for Hydrobioloy.

　　报告简介：

　　He will present a few case studies which present well the broad topics, which they currently investigate at their Institute for Hydrobiology at the TU Dresden.

　　The first topic relates to the analysis of wastewater treatment plants and their impact on freshwater systems. Scientists are increasingly interested in the role of wastewater treatment plants (WWTPs) as a sink and source for antibiotic resistant bacteria and their genes. To date, the dynamics of resistant bacteria and associated genes in municipal WWTPs remains relatively unexplored, but there is clear evidence that antibiotic resistant organisms and genes are released with WWTP effluents to receiving environments. I will present the results of an European consortium on a coordinated investigation of WWTPs and the corresponding antibiotics and antibiotic resistance genes and the resulting recommendations for future analyses.

　　The second topic relates to biomonitors of wastewater effluents in freshwater systems and how this is currently applied. Especially the development of early warning systems is here in the focus of the current endavours. For this we couple biomonitors with online systems and also apply special algorithms to identify alarm signals.

　　In the third topic I will focus on a currently endangered species in Germany, the freshwater pearl mussel. Here our Institute currently works on methods to re-establish the currently highly endangered population. We have developed also molecular techniques such as e-DNA to detect rare individuals within the water sediment and I present some first results on the verification of this method.
