Abstract [en]

This report investigates the presence of Nosema in Sweden. Nosema is an intracellular parasite within the order Microsporidia and is considered a global threat. The most recent academic study on the presence of Nosema in Sweden was published in 2013, however in that study no presence of Nosema in the north of Sweden was reported. The aim of this study was to explore the presence of Nosema in Sweden, particularly in the north of Sweden. Samples were gathered from different locations in Sweden, and thereafter analysed (n=74), 54 samples were analysed under microscope. A geographical map was created to establish the range of Nosema on a global perspective. PCR primers and FISH gene probes for molecular identification were evaluated and tested both in SILVA and in an own database created in the bioinformatics software package ‘ARB’. Main findings of the study were that Nosema were detected in two samples in Sweden and that further studies with more sophisticated methods and better sequencing needs to be developed in order to fully investigate the presence of Nosema in the north of Sweden.
