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.

Humoral immune response to Shiga Toxin 2 (Stx2) among Brazilian urban children with hemolytic uremic syndrome and healthy controls [PDF]

open access: yes, 2014
Background: Shiga toxin (Stx)-producing Escherichia coli (STEC) infection is associated with hemolytic uremic syndrome (HUS), the main cause of acute renal failure in early childhood.

Nanobodies: A Promising Toolkit for Diagnostic Applications

open access: yesSmartMat, Volume 7, Issue 3, June 2026.
This review focuses on camelid‐derived nanobodies (VHHs) and explains how their small size and high stability support robust diagnostic design. Applications across ELISA, lateral flow assays, and PET/SPECT imaging are summarized, along with clinical progress such as caplacizumab.

Quantitative Detection of Shiga Toxins Directly from Stool Specimens of Patients Associated with an Outbreak of Enterohemorrhagic Escherichia coli in Japan—Quantitative Shiga toxin detection from stool during EHEC outbreak

open access: yesToxins, 2015
Detection of Shiga toxins (Stx) is important for accurate diagnosis of Enterohemorrhagic Escherichia coli infection. In this study, we quantitatively analyzed Stx protein in nine patients’ stool during an outbreak that occurred in Japan.

A systematic review and meta-analysis of the epidemiology of pathogenic Escherichia coli of calves and the role of calves as reservoirs for human pathogenic E. coli [PDF]

open access: yes, 2015
Escherichia coli bacteria are the most common causes of diarrhea and septicemia in calves. Moreover, calves form a major reservoir for transmission of pathogenic E. coli to humans.

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.

Prevalence, Biogenesis, and Functionality of the Serine Protease Autotransporter EspP

open access: yes, 2013
Enterohemorrhagic E. coli (EHEC) causes severe diseases in humans worldwide. One of its virulence factors is EspP, which belongs to the serine protease autotransporters of Enterobacteriaceae (SPATE) family. In this review we recapitulate the current data

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.

OMV-based vaccine formulations against Shiga toxin producing Escherichia coli strains are both protective in mice and immunogenic in calves

open access: yesHuman Vaccines & Immunotherapeutics, 2018
Strains of Shiga toxin-producing Escherichia coli (STEC) can cause the severe Hemolytic Uremic Syndrome (HUS). Shiga toxins are protein toxins that bind and kill microvascular cells, damaging vital organs.

A Poly-N-Acetylglucosamine−Shiga Toxin Broad-Spectrum Conjugate Vaccine for Shiga Toxin-Producing Escherichia coli [PDF]

open access: yes, 2014
Many pathogens produce the β-(1−6)-linked poly-N-acetylglucosamine (PNAG) surface polysaccharide that is being developed as a broadly protective antimicrobial vaccine. However, it is unknown whether systemically injected PNAG vaccines or antibodies would
