Article Synopsis
  • Two strains of bacteria were isolated from poultry facilities in Ukraine in 2023: OR12-like strain ChP2023 from broiler chickens and NCTC 11168R-like strain KF2023 from turkeys.
  • Their genomes were sequenced using Oxford Nanopore Technologies, with sizes of 1,713,995 bp and 1,729,995 bp, respectively.
  • Both genomes contained genes associated with antibiotic resistance and other factors that contribute to their ability to cause disease.

Article Synopsis
  • * Out of 100 IDPs tested, 11% were found to have HCV while none tested positive for HIV; approximately half of the participants reported a history of injecting drugs.
  • * IDPs with drug use experience had significantly lower knowledge about HIV compared to non-drug users, indicating a need for improved education and testing resources, while both groups showed similar HCV knowledge.

Biocatalytic engineering was carried out by varying monotonically the binary CNTs-silica composition and, accordingly, the physicochemical characteristics of adsorbents developed for immobilization of recombinant T. lanuginosus lipase (rPichia/lip). The adsorbents based on composite carbon-silica materials (CCSMs) were produced by impregnating finely dispersed multi-walled carbon nanotubes with silica hydrosol followed by calcination in argon at 350°C; the mass ratio of the hydrophobic and the hydrophilic components varied over a wide range.

is an important zoonotic parasite worldwide, but it has received limited attention in Ukraine. A seroepidemiological study was conducted and samples from 452 wild boars that had been hunted in 2006-2011 in 23 of the 25 regions of Ukraine were tested to estimate . seroprevalence.

Article Synopsis
  • African swine fever (ASF) is a deadly viral disease affecting pigs, originating from Africa, and has been spreading in Europe and Asia since its emergence in Georgia in 2007.
  • In Ukraine, the highest number of ASF outbreaks occurred in 2017 and 2018, with a notable spread pattern moving from eastern and northern borders towards western and southern regions.
  • The analysis indicates that while wild boars played a key role in early ASF spread, human activities have become the main driver in recent years, with effective mitigation strategies leading to a decline in outbreaks since 2019, though complete eradication remains a challenge.
