Day-to-day dynamics of commensal Escherichia coli in Zimbabwean cows evidence temporal fluctuations within a host-specific population structure [PDF]

, 2017
To get insights into the temporal pattern of commensal Escherichia coli populations, we sampled the feces of four healthy cows from the same herd in the Hwange District of Zimbabwe daily over 25 days. The cows had not received antibiotic treatment during

Enterohaemorrhagic and other Shiga toxin‐producing Escherichia coli (STEC): Where are we now regarding diagnostics and control strategies?

Transboundary and Emerging Diseases, 2018
Escherichia coli comprises a highly diverse group of Gram-negative bacteria and is a common member of the intestinal microflora of humans and animals. Generally, such colonization is asymptomatic; however, some E.

Prevalence, virulence potential, and pulsed-field gel electrophoresis profiling of Shiga toxin-producing Escherichia coli strains from cattle

Gut Pathogens, 2017
Background As a primary source of Shiga-toxin-producing Escherichia coli (STEC) infection, cattle are often targeted to develop strategies for reducing STEC contamination.

Salmonella manipulates macrophage migration via SteC-mediated myosin light chain activation to penetrate the gut-vascular barrier

EMBO Journal
The intestinal pathogen Salmonella enterica rapidly enters the bloodstream after the invasion of intestinal epithelial cells, but how Salmonella breaks through the gut-vascular barrier is largely unknown.

Sensitivity of lunar particle-detection experiments [PDF]

, 2016
The use of the Moon as a detector volume for ultra-high-energy neutrinos and cosmic rays, by searching for the Askaryan radio pulse produced when they interact in the lunar regolith, has been attempted by a range of projects over the past two decades. In

MOLECULAR CHARACTERIZATION OF ENTEROPATHOGENIC E. COLI (EPEC) AND SHIGA-TOXIN PRODUCING E. COLI (STEC) FROM DOMESTIC ANIMALS: PREVALENCE, VIRULENCE, COLONIZATION FACTORS AND THEIR ANTIMICROBIAL RESISTANCE [PDF]

Exploratory Animal and Medical Research
To ascertain the presence and molecular characterization of enteropathogenic and Shiga toxin E. coli, 200 fecal samples were collected from rabbits (24), slaughtered pigs (22), calves (39), poultry (41), dogs (38), sheep and goats (36).

Impact of Shiga-toxin encoding gene transduction from O80:H2 Shiga toxigenic Escherichia coli (STEC) on non-STEC strains

Scientific Reports, 2022
AbstractShiga toxin-producing Escherichia coli (STEC) are major foodborne pathogens that cause human diseases ranging from diarrhea to life-threatening complications including hemolytic–uremic syndrome. Virulence of STEC strains and their ability to cause severe diseases are associated with the activity of prophage-encoded Shiga toxins (Stxs).

Limits on the validity of the thin-layer model of the ionosphere for radio interferometric calibration [PDF]

, 2016
For a ground-based radio interferometer observing at low frequencies, the ionosphere causes propagation delays and refraction of cosmic radio waves which result in phase errors in the received signal.
