Characterization of tailocins of Pragia fontium 24613 and the tailocin loci within the family Budviciaceae.

Res Microbiol

November 2024

Department of Biology, Faculty of Medicine, Masaryk University, Kamenice 753/5, 625 00, Brno, Czech Republic. Electronic address:

Article Synopsis
  • Tailocins are tiny protein complexes that act like phage tails and can inhibit closely related bacterial species, with R-type being common in Gammaproteobacteria and F-type being rare.
  • This study focused on a freshwater isolate, Pragia fontium 24613, which produces both R- and F-type tailocins, analyzing their ability to inhibit clinically relevant bacteria and identifying the related gene cluster.
  • The results showed that disrupting a specific protein affected R-tailocin production, and a comparison of genes revealed R-type tailocins are widely conserved among certain bacteria, while F-type tailocins show less conservation and presence, highlighting their antimicrobial potential against important pathogens.

Article Synopsis
  • Aquatic environments contain antibiotic-resistant bacteria, but the specific presence of polymyxin-resistant Yersinia enterocolitica, which causes yersiniosis, is not well-studied until now.
  • Researchers isolated polymyxin-resistant strains from natural water, showing resistance to multiple antibiotics and a high capability to cause disease in the model organism Galleria mellonella, leading to a 90% mortality rate within 48 hours.
  • Whole genome sequencing revealed 26 antibiotic resistance genes and a close genetic relationship to strains from humans and swine, indicating that polymyxin-resistant Y. enterocolitica could be a significant health threat to humans.

Department of Biological and Environmental Science and Nanoscience Center, University of Jyväskylä, Jyväskylä, Finland.

Yersinia enterocolitica causes yersiniosis, the third most common gastrointestinal infection in humans throughout Europe. The emergence of multidrug resistance and the lack of effective new antibiotics have drawn attention to phage therapy as a treatment option. Here, we report the complete genome sequence of phage fMtkYen3-01, which infects Y.

, a species within the genus , thrives optimally at 22-25°C but can also grow at the mammalian core body temperature of 37°C. This dual temperature adaptability necessitates establishing both temperature conditions in research to examine the effects on various biological processes. In quantitative real-time PCR (qRT-PCR) assays, the selection of appropriate housekeeping genes is vital for data accuracy.
