Top-Down Proteomic Identification of Shiga Toxin 1 and 2 from Pathogenic Escherichia coli Using MALDI-TOF-TOF Tandem Mass Spectrometry

open access: yesMicroorganisms, 2019
Shiga-toxin-producing Escherichia coli (STEC) are a burden on agriculture and a threat to public health. Rapid methods are needed to identify STEC strains and characterize the Shiga toxin (Stx) they produce.

Isolation of verotoxin-producing Escherichia coli associated with diarrhoea in Malaysia containing plasmids showing homology with biotinylated Shiga-like toxin DNA gene probes [PDF]

open access: yes, 1996
Three strains of verotoxin-producing Escherichia coli isolated from patients with haemorrhagic colitis harboured plasmids ranging in size from 2.7 kb to 91.2 kb. Those plasmids ranging from 2.7 kb to 6.8 kb hybridized to Shiga-like toxin I and Shiga-like

Gene‐specific double‐stranded RNAs induce mortality in the South African mealybug Delottococcus aberiae

open access: yesPest Management Science, Volume 82, Issue 6, Page 5184-5194, June 2026.
Gene‐specific double‐stranded RNAs effectively silence essential genes in the invasive citrus pest Delottococcus aberiae, leading to significant mortality through both microinjection and oral delivery. These results provide proof of concept for RNA interference‐based biopesticides as selective and sustainable tools for citrus integrated pest management.

Environmental Preferences and Functional Variations of Methanotrophs in Northeast Qinghai‐Tibet Plateau Wetlands

open access: yesEnvironmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Significant environmental preference between type I and type II methanotrophs is regulated by soil ion concentration (pH and electrical conductivity) in wetlands. Type II methanotrophs (Methylocystis, etc.) contributes more to soil methane oxidation than type I methanotrophs.

Common Hematologic Emergencies—Acute Promyelocytic Leukemia and Microangiopathic Hemolytic Anemias—A Pivotal Role of Clinical Laboratory

open access: yesInternational Journal of Laboratory Hematology, Volume 48, Issue 3, Page 521-530, June 2026.
ABSTRACT Hematologic emergencies are urgent health conditions which result in significant mortality and morbidity unless timely therapeutic measures are taken. Therapeutic success depends on their timely and accurate recognition by hematology laboratory services.

Genotyping and antimicrobial resistance patterns of Escherichia coli O157 originating from cattle farms [PDF]

open access: yes, 2011
During a Escherichia coli O157 prevalence study on cattle farms, 324 E. coli O157 isolates were collected from 68 out of 180 cattle farms. All isolates harbored the eaeA gene and the enterohemolysin (ehxA) gene. The majority of the strains only contained

Functionalized Diaryliodonium Salts with N‐Reactive Amides: Versatile Reactivity for Constructing Benzo‐Fused Nitrogen Heterocycles

open access: yesAdvanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A practical one‐pot strategy for the synthesis of ortho‐amide‐functionalized TMP‐iodonium(III) salts has been developed. These iodonium salts exhibited distinct reactivities toward N‐, O‐, and S‐nucleophiles, facilitating arylocyclization and producing a variety of benzo‐fused heterocycles under mild conditions.

Characterization of Rabbit Polyclonal Sera against Recombinant Shiga Toxin and its Subunits for Detection of Stx-Producing E. coli

open access: yesIranian Journal of Allergy, Asthma and Immunology, 2011
Shiga toxin (Stx) is the principal virulence factor of Shigatoxigenic Escherichia coli (STEC), a food-born pathogen associated disease with uncomplicated diarrhea or the hemolytic-uremic syndrome.

Large scale expansion of mobile elements in specific hotspot regions of the German outbreak _Escherichia coli_ O104:H4 [PDF]

open access: yes, 2011
The outbreak strain of _E. coli_ O104:H4 has been sequenced by several groups and made available publicly for CrowdSourcing purposes. Genome comparisons of the complete finished sequence of TY2482 (BGI), have been made with the draft assemblies of ...

Microarray-based screening of differentially expressed genes of E. coli O157:H7 Sakai during preharvest survival on butterhead lettuce [PDF]

open access: yes, 2016
Numerous outbreaks of Escherichia coli O157:H7 have been linked to the consumption of leafy vegetables. However, up to the present, little has been known about E.
