The long polar fimbriae (lpf) operon and its flanking regions in bovine Escherichia coli O157:H43 and STEC O136:H12 strains [PDF]
, 2013 Long polar fimbriae (Lpf) are intestinal adhesins and important virulence factors of pathogenic Escherichia coli strains. We cloned and sequenced the lpf2-1 operon (lpf2ABCD) and its flanking regions of an intimin- and Shiga toxin-negative E.

The Effect of Lactic Acid in Association With Steam in Reducing Microorganisms in Soft Wheat
Cereal Chemistry, Volume 103, Issue 3, Page 288-299, May/June 2026.ABSTRACT Background and Objectives Within the food industry, steam is an effective method of microbial reduction for a variety of products. Previous studies have shown that tempering soft wheat with organic acids, as well as steam application, can potentially reduce wheat's microbial load with minor changes in the functional properties of the flour ...

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.Tibetan pig farms host diverse Escherichia coli strains that resist multiple antibiotics and carry important disease genes, such as astA. These traits jump easily between bacterial groups, marking intensive pig production as a key reservoir and signalling the need for integrated animal–human surveillance and more careful antibiotic use.

Introducing Reflected GNSS TEC Data Into ANCHOR Ionospheric Data Assimilation Model
Space Weather, Volume 24, Issue 5, May 2026.Abstract ANCHOR is a novel data assimilation (DA) algorithm developed at the U.S. Naval Research Laboratory to improve ionospheric nowcasting by increasing accuracy and decreasing computational cost. As a parameterized DA model, ANCHOR represents the ionosphere using physical parameters such as the F2 layer peak (Nm $Nm$F2), which characterizes a ...

Space Weather, Volume 24, Issue 5, May 2026.Abstract This study evaluates 17 ionospheric models' performance over the Continental United States (CONUS) during the 2024 Mother's Day geomagnetic storm, using ground‐based GNSS Total Electron Content (TEC) and single‐frequency (SF) precise Single Point Positioning (SPP) technique. The storm produced significant positive storm effects during its main
