Molecular and Serological Characteristics of Avian Pathogenic Escherichia coli Isolated from Various Clinical Cases of Poultry Colibacillosis in Poland

Animals, 2022
Escherichia coli infections are a major problem in modern poultry production. Avian pathogenic E. coli (APEC) strains have several mechanisms that enable them to colonize various ecosystems. In this study, 290 E.

Space microgravity increases expression of genes associated with proliferation and differentiation in human cardiac spheres

npj Microgravity, 2023
Efficient generation of cardiomyocytes from human-induced pluripotent stem cells (hiPSCs) is important for their application in basic and translational studies. Space microgravity can significantly change cell activities and function.

Insertion sequence contributes to the evolution and environmental adaptation of Acidithiobacillus

BMC Genomics, 2023
Background The genus Acidithiobacillus has been widely concerned due to its superior survival and oxidation ability in acid mine drainage (AMD). However, the contribution of insertion sequence (IS) to their biological evolution and environmental ...

Human mesenchymal stem cell responses to hydrostatic pressure and shear stress [PDF]

European Cells & Materials, 2016
The effects of mechanical stimuli to which cells are exposed in vivo are, at best, incompletely understood; in this respect, gene-level information regarding cell functions which are pertinent to new tissue formation is of special interest and importance

Correlation Between the Transcriptional Level of iss and bor Virulence Genes of Avian Pathogenic Escherichia Coli O78 Inoculated to Chicken Serum [PDF]

Iranian Journal of Veterinary Medicine, 2021
BACKGROUND: Blue Open Reading (bor) and increased serum survival (iss) genes, with intense structural and possible functional similarities, engage in the serum resistance of Avian Pathogenic Escherichia coli O78 (APEC-O78).

Insertion sequence transposition inactivates CRISPR-Cas immunity

Nature Communications, 2023
CRISPR-Cas immunity systems safeguard prokaryotic genomes by inhibiting the invasion of mobile genetic elements. Here, we screened prokaryotic genomic sequences and identified multiple natural transpositions of insertion sequences (ISs) into cas genes ...

Genomic Characterization of Potential Plant Growth-Promoting Features of Sphingomonas Strains Isolated from the International Space Station

Microbiology Spectrum, 2022
In an ongoing microbial tracking investigation of the International Space Station (ISS), several Sphingomonas strains were isolated. Based on the 16S rRNA gene sequence, phylogenetic analysis identified the ISS strains as Sphingomonas sanguinis (n = 2 ...
