Identification of Potential Vaccine Strains of Escherichia coli Isolates From Diarrhoeic Calves

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study aimed to identify vaccine candidate Escherichia coli strains isolated from diarrheic calves. Faecal samples collected from 500 calves were analysed, and E. coli strains were isolated and characterized phenotypically and genotypically. Antibiotic resistance profiles, virulence‐associated genes and MLVA genotyping were used to select 20 ...

E. coli a-hemolysin: a membrane-active protein toxin

Brazilian Journal of Medical and Biological Research, 1998
Alpha-Hemolysin is synthesized as a 1024-amino acid polypeptide, then intracellularly activated by specific fatty acylation. A second activation step takes place in the extracellular medium through binding of Ca2+ ions. Even in the absence of fatty acids and Ca2+ HlyA is an amphipathic protein, with a tendency to self-aggregation. However, Ca2+-binding

Characterisation of Haemolytic Uropathogenic Escherichia coli Isolated From Dogs and Cats

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
The present study characterises 51 canine and feline haemolytic E. coli isolates from urinary tract infections by a polyphasic approach, including susceptibility testing, CH‐clonotyping, and DNA microarrays. The majority of isolates belonged to phylogenetic group B2 and were classified as extraintestinal pathogenic E.

Mycotoxins in Basidiomycete Mycelium and Fruiting Bodies: Implications for Eu Novel Food Assessment and Selected International Regulatory Frameworks

Comprehensive Reviews in Food Science and Food Safety, Volume 25, Issue 5, September 2026.
ABSTRACT Advances in technology have enabled the efficient and sustainable production of basidiomycete vegetative mycelium, particularly from Pleurotus species, as a novel food source. However, mycelium has yet to receive regulatory approval in many global markets, requiring a better understanding of factors affecting its safety.

Egy virulencia regulátor mutáns Salmonella enterica törzs mint kereszt-immunitást biztosító orális vakcina jelölt vizsgálata = Investigation of a virulence regulator mutant strain of Salmonella enterica as a candidate for live oral vaccine providing cross-immunity [PDF]

, 2008
Kutatásaink során egy Salmonella rfaH mutánst mint potenciális vakcina jelöltet vizsgáltunk több aspektusból. Mivel az RfaH fehérje egy transzkripciós regulátor, vizsgáltuk, hogy mely virulencia faktorokra kifejtett hatása okozza a vakcina törzs ...

P2X-Receptor Antagonists Inhibit the Interaction of S. aureus Hemolysin A with Membranes

Toxins, 2017
The pore forming hemolysin A, Hla, is a major virulence factor of Staphylococcus aureus. Apparently, 1–2 pore(s) per cell suffice(s) to cause cell death.

Comparison of O-polysaccharide and hemolysin co-regulated protein as target antigens for serodiagnosis of melioidosis

PLOS Neglected Tropical Diseases, 2017
La melioidosis es una enfermedad grave causada por Burkholderia pseudomallei. Las manifestaciones clínicas son diversas y las infecciones agudas requieren tratamiento inmediato con antibióticos eficaces. Si bien el cultivo es el estándar de diagnóstico actual, consume mucho tiempo y tiene una baja sensibilidad.

In-Depth Analysis of Exoproteomes from Marine Bacteria by Shotgun Liquid Chromatography-Tandem Mass Spectrometry: the Ruegeria pomeroyi DSS-3 Case-Study [PDF]

, 2010
Microorganisms secrete into their extracellular environment numerous compounds that are required for their survival. Many of these compounds could be of great interest for biotechnology applications and their genes used in synthetic biology design.

Syndromic Convergence in Aquaculture Disease Management: A Critical Review of Climate‐Pathobiome Interactions, Diagnostic Frameworks, and Knowledge Gaps

Reviews in Aquaculture, Volume 18, Issue 4, September 2026.
Syndromic convergence (SyCo) reframes aquaculture disease as the synergistic product of climate‐driven stressors, pathobiome communities, and host immune compromise, not single pathogens. A five‐criterion scoring matrix, composite early warning index, and three‐layer intervention framework together operationalize this shift toward predictive ...
