Genetic diversity and multidrug resistance of phylogenic groups B2 and D in InPEC and ExPEC isolated from chickens in Central China

BMC Microbiology, 2022
Background Avian colibacillosis is an infectious bacterial disease caused by avian pathogenic Escherichia coli (APEC). APEC causes a wide variety of intestinal and extraintestinal infections, including InPEC and ExPEC, which result in enormous losses in ...

Effects of TolC on the pathogenicity of porcine extraintestinal pathogenic Escherichia coli

Frontiers in Immunology, 2022
Extraintestinal pathogenic Escherichia coli (ExPEC) is a well-known critical pathogenic zoonosis that causes extraintestinal infections in humans and animals by affecting their immune organs. Recently, research on the outer membrane protein of E.

Designing invert emulsion drilling fluids for high temperature and high-pressure conditions

Scientific Reports
Good and optimal rheology is a primary requisite for a drilling fluid to achieve better hole-cleaning and barite sag resistance. Conventional thickeners like organophilic clay that provide rheology to invert emulsion fluids degrade with time and thereby ...

Extraintestinal pathogenic Escherichia coli utilizes the surface-expressed elongation factor Tu to bind and acquire iron from holo-transferrin

Virulence, 2022
Extraintestinal pathogenic Escherichia coli (ExPEC) is a common anthropozoonotic pathogen that causes systemic infections. To establish infection, ExPEC must utilize essential nutrients including iron from the host.

A Single‐Nucleotide Substitution Generates a de Novo Promoter That Activates a Latent Metabolic Bypass in Escherichia coli

Molecular Microbiology, EarlyView.
A chromosomal mutation allows bypass of deletion of the Escherichia coli fabH gene. The bypass results from creation of a new promoter that drives increased madA transcription, resulting in increased synthesis of acetyl‐acyl carrier protein by decarboxylation of malonyl‐acyl carrier protein.

Expecation Gap in Surabaya: The Assessment Between Auditors With Audit Report Users

Indonesian Journal of Social Science Research, 2021
Expectation gaps always occur in companies where there is a difference between what public accountants (auditors) believe to be their responsibilities and what users of financial statements want. Thus this study discusses the expectation gap which aims to determine the performance of auditors in performing any audit work, to know the reactions of audit

Global Genomic Epidemiology of Escherichia coli (ExPEC) ST38 Lineage Revealed a Virulome Associated with Human Infections

Microorganisms, 2022
Background: Most of the extraintestinal human infections worldwide are caused by specific extraintestinal pathogenic Escherichia coli (ExPEC) lineages, which also present a zoonotic character. One of these lineages belongs to ST38, a high-risk globally disseminated ExPEC. To get insights on the aspects of the global ST38 epidemiology and evolution as a
