A new protocol employing nested PCR-restriction fragment length polymorphism (RFLP) based on the flaB gene and two restriction enzymes was worked out. This protocol allows the identification of all Borrelia species transmitted by Ixodes ricinus in Europe, including Borrelia miyamotoi and 3 genetic variants of B. garinii. A dendrogram of flaB sequence similarity was in accordance with RFLP variants.

The western European hedgehog () and the northern white-breasted hedgehog () are natural hosts of the tick , the vector of tick-borne pathogens such as the bacteria responsible for Lyme disease. The aim of this study was to identify these pathogens in ticks collected from hedgehogs in northwestern Poland and to assess their genetic diversity by molecular analysis of the detected pathogens based on the gene and the intergenic spacer. Among 101 hedgehogs examined, 737 ticks were found on 56 (55.

Aims: The aim of this study was to evaluate the antioxidant and anti-inflammatory effects of marine fungal cerebroside flavuside B (FlaB) on Staphylococcus aureus-infected keratinocytes in in vitro skin wounds and to identify FlaB targets in bacterial and human cells.
Methods And Results: A combination of enzyme-linked immunosorbent assay (ELISA), plate spectrofluorimetry, and flow cytometry with fluorescence dye staining, scratch assay, and real-time cell imaging techniques was used to investigate the effects of FlaB on S. aureus-infected HaCaT keratinocytes.

Gene regulation at the post-transcriptional level is prevalent in all domains of life. In bacteria, ProQ-like proteins have emerged as important RNA chaperones facilitating RNA stability and RNA duplex formation. In the major human pathogen Vibrio cholerae, post-transcriptional gene regulation is key for virulence, biofilm formation, and antibiotic resistance, yet the role of ProQ has not been studied.

Ixodes ricinus tick is a vector of bacteria of Borreliella genus and Borrelia miyamotoi. Exposure to ticks constitutes occupational risk to soldiers, but the current knowledge on this subject is still limited. Therefore, the aim of this study was to evaluate tick abundance and prevalence of infection with Borreliella spp.
