New project and postdoc opportunity
I am excited to let you know that we are diving into a whole new project in collaboration with Swedish University of Agriculture (SLU) and Vattenbrukscentrum Norr (VBC).
We aim to hire a postdoctoral researcher within the frame work of the EC postdoctoral programme run by UCMR and UPSC at Umeå University. Please check out the link for more information how to apply. The deadline is 2023-10-29! We seek highly motivated candidates from all over the world and especially female applicants are encouraged!
Our project proposal focuses on the identification of novel and more efficient compounds against the common fish pathogenic Saprolegnia spp (Figure 1).
Swedish aquaculture is a small but well-developed industry with high standards regarding animal health and welfare. Still, pathogens are a serious threat to the welfare of captive fish. Oomycetes of the genus Saprolegnia are widespread problems in fish hatcheries and current therapies are solely based on hazardous chemicals. Therefore, we aim to establish a laboratory assay for hyphal growth of Saprolegnia spp. and determine essential genetic queues governing filamentation. Based on this, we aim to identify and test anti-germinating and hyphal-blocking compounds against Saprolegnia to prevent growth of the pathogenic form. Proof-of-concept tests will be performed at Vattenbrukscentrum Norr AB on infected fish eggs. We will use established omics techniques to investigate gene circuits which govern filamentation of Saprolegnia parasitica and other species. Based on these findings, we will test chemical and natural compounds which inhibit Saprolegnia filamentation, boost infection resistance of fish or both.
C. Urban has long standing experience with human fungal pathogens serving as fundament to identify essential genes. L. Persson and H. Jeuthe will provide extensive knowledge in fish biology and aquaculture needed to perform proof of concept evaluations in natural environments. The study will inspire new anti-Saprolegnia compounds which are urgently needed to improve environmental conditions in Swedish fish hatcheries.
