Introduction
Ornithology, Game Resources, Zoonosys, Ecology, Mammalogy. Centre for the study of transborder and emergent diseases and zoonosys is the youngest department of the Danube Delta National Institute of Research – Development – Tulcea approved for establishment in 2015 and materialized in 2016. By diversifying research skills, collaboration with prestigious European teams and participating in visits and international conferences it has appeared the initiative of establishing a Department with this profile. From the beginning, it was decided to investigate pathogenic agents not only in terms of human and domestic livestock damage but also in terms of wildlife conservation.

BSTRACT. The European mink (Mustela lutreola L.) is critically endangered. The Danube Delta Biosphere Reserve (DDBR) is one of the last refuges of this species. Within the DDBR the European mink is still widespread as indicated by 74 life captures in a number of expeditions between 2003 and 2011. No American mink (Neovison vison), a serious threat...

In this study the first complete sequence of the West Nile virus (WNV) lineage 2 strain currently circulating in Romania was determined. The virus was detected in a Hyalomma marginatum marginatum tick collected from a juvenile song thrush (Turdus philomelos) in the Romanian Danube Delta close to the city of Tulcea, end of August 2013. Our finding e...

Danube Delta Biosphere Reserve (DDBR) overlaps over two Special Protected Areas, with 89 species in Annex 1 of the Birds Directive. The number of many bird species in the Danube Delta varied widely over the last decades, most often due to the anthropogenic factor, directly (persecution, hunting) and/or indirectly (habitat changes). In the present p...
