Metagenomic Characterization of the Human Intestinal Microbiota in Fecal Samples from STEC-Infected Patients [PDF]

Frontiers in Cellular and Infection Microbiology, 2018
The human intestinal microbiota is a homeostatic ecosystem with a remarkable impact on human health and the disruption of this equilibrium leads to an increased susceptibility to infection by numerous pathogens. In this study, we used shotgun metagenomic

Molecular Characterization of Virulent Genes and Antimicrobial Resistance Patterns of Escherichia coli Isolated From Calf Scours in Western Iran. [PDF]

Vet Med Sci
This study in Western Iran analysed E. coli in diarrhoeic neonatal calves and identified 307 isolates from 350 faecal samples. The pathotypes included EHEC (36.59%), EPEC (20.42%), ETEC (14.46%), STEC (12.34%) and NTEC (11.48%), with four STEC O157:H7 isolates. Serotypes O103 and O15 were the most common.

Effect of the vaccination against Shiga toxin 2e in a farm with history of oedema disease, caused by atypical Escherichia coli producing Shiga toxin (STEC)

Veterinární Medicína, 2022
Oedema disease of weaned piglets is caused by shigatoxigenic Escherichia coli (STEC), typically harbouring the stx2e gene and F18 adhesins. The aim of this study was to assess the effect of a commercially available oedema disease vaccine on the ...

Detection and Molecular Characterization of Some Virulence Genes of Escherichia Coli Isolated from Milk in Dairy Cow Farms [PDF]

Journal of Applied Veterinary Sciences, 2023
Coliform pathogens, primarily E. coli, were discovered throughout the farm, causing environmental mastitis and can be shed from the udder into the milk; they are concerned about severe gastrointestinal disruption and potential enteropathogenic and/or ...

Prevalence, Antimicrobial Resistance, and Whole Genome Sequencing Analysis of Shiga Toxin-Producing Escherichia coli (STEC) and Enteropathogenic Escherichia coli (EPEC) from Imported Foods in China during 2015–2021

Toxins, 2022
Shiga toxin-producing Escherichia coli (STEC) and enteropathogenic Escherichia coli (EPEC) are foodborne pathogens that cause hemolytic uremic syndrome and fatal infant diarrhea, respectively, but the characterization of these bacteria from imported food

SteC and the intracellular Salmonella‐induced F‐actin meshwork

Cellular Microbiology, 2021
Salmonella enterica serovars infect a broad range of mammalian hosts including humans, causing both gastrointestinal and systemic diseases. Following uptake into host cells, bacteria replicate within vacuoles (Salmonella‐containing vacuoles; SCVs ...

Control of gas concentration distribution in a semiconductor process chamber using CT-TDLAS measurement

AIP Advances, 2021
Methane (CH4) concentration distribution in a semiconductor process chamber was controlled using the measurement of computed tomography-tunable diode laser absorption spectroscopy (CT-TDLAS) and the feedback control toward the feeding CH4 concentrations ...

Prevalence and Antibiogram profiles of STEC strains isolated from raw cow's milk in New-Valley Governorate, Egypt

SVU-International Journal of Veterinary Sciences, 2022
A cross sectional study was conducted to isolate and identify Shiga toxinproducing Escherichia coli (STEC) from raw cow milk. A total of 267 milk samples were collected from apparently healthy cattle in 7 different dairy farms.

Virulence Profiling and Molecular Typing of Shiga Toxin-Producing E. coli (STEC) from Human Sources in Brazil

Microorganisms, 2020
Since no recent data characterizing Shiga toxin-producing E. coli (STEC) from human infections in Brazil are available, the present study aimed to investigate serotypes, stx genotypes, and accessory virulence genes, and also to perform pulsed-field gel ...
