Structural and mutational analysis of Methanosarcina mazei prenylated FMN synthase reveals the basis of its unique prenyl donor substrate specificity

The FEBS Journal, EarlyView.
Some prenylated flavin mononucleotide (prFMN) synthases exceptionally prefer dimethylallyl phosphate (DMAP) over dimethylallyl diphosphate (DMAPP), which is a common prenyl donor substrate for many prenyltransferases. Structural and mutagenic analyses of Methanosarcina mazei prFMN synthase, which prefers DMAP but can also accept DMAPP, elucidated its ...

Sharp Transition in the Immunoimmobilization of E. coli O157:H7

Langmuir, 2014
This work focuses on immobilization of living enterohemorrhagic Escherichia coli O157:H7 on a gold surface as a function of the concentration of antibody tethered to the surface in the physiological environment of the organisms. Experiments are conducted using antibodies raised against bacterial surface lipopolysaccharides (LPS) tethered to gold-coated

The Oral‐Gut Axis: Bidirectional Interactions Between Microbiome and Diseases

Journal of Periodontal Research, EarlyView.
This study aims to summarize the mechanisms underlying ectopic colonization of the gut by oral pathobionts and the microbial and host factors that regulate this process. ABSTRACT Increased colonization of typically oral microorganisms is frequently observed in the gut mucosa or lumen of individuals with gastrointestinal disorders, including patients ...

Characterization of non -Shiga toxin- producing Escherichia coli O157 strains isolated from dogs Caracterización de cepas de Escherichia coli O157 no productoras de toxina Shiga aisladas de perros

Revista Argentina de Microbiología, 2010
Shiga toxin-negative Escherichia coli O157 strains of various H types have been associated with diarrhea in children and are considered potentially pathogenic for humans. In this study, we describe non-Shiga toxin-producing E. coli O157 E.

Pathogenicity of Escherichia coli O157 in commercial broiler chickens

Beni-Suef University Journal of Basic and Applied Sciences, 2018
Broiler chickens are frequently infected with Escherichia coli (E. coli), which often results in disease and high economic losses. The most affected ages to infections with E. coli are chickens from 4 to 5 weeks.

Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

Medical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.

Chlorination of pathogenic E coli O157

Water Science and Technology, 1998
Foodborne outbreaks of infectious disease caused by enteropathogenic E coli O157 have occurred throughout Japan since 1996. This study was undertaken to check whether commonly used chlorination could effectively inactivate E coli O157 in water. Pathogenic E coli 157 could be as easily inactivated by chlorine as non-pathogenic E coli K12.
