Natural Bone‐Derived Ceramic Scaffolds Functionalized with Chitosan‐Gold, Chitosan‐Magnesium, and Chitosan‐Zinc for Enhanced Antibacterial Activity

Advanced Engineering Materials, Volume 28, Issue 14, 22 July 2026.
This study reports the development of antibacterial ceramic scaffolds derived from natural bovine bone. The bones were processed through sequential boiling and hydrogen peroxide treatment to remove organic matter, producing porous, mineral‐rich scaffolds.

Birds of prey and the city: variation in immunity and parasites exposure along an urbanization gradient

Journal of Avian Biology, Volume 2026, Issue 4, July 2026.
Pathogens are major ecological and evolutionary forces, and the immune system is central to coping with these challenges. Environmental variation, including urbanisation, can alter both pathogen exposure and immune function, making it important to understand how responses vary across habitats.

High frequency of hybrid Escherichia coli strains with combined Intestinal Pathogenic Escherichia coli (IPEC) and Extraintestinal Pathogenic Escherichia coli (ExPEC) virulence factors isolated from human faecal samples

BMC Infectious Diseases, 2018
Background Classification of pathogenic Escherichia coli (E. coli) has traditionally relied on detecting specific virulence associated genes (VAGs) or combinations thereof. For E.

Avian pathogenic Escherichia coli MT78 invades chicken fibroblasts

Veterinary Microbiology, 2011
Avian pathogenic Escherichia coli (APEC) are responsible for extraintestinal diseases, called colibacillosis, in avian species. The most severe manifestation of the disease is colisepticemia that usually starts at the respiratory tract and may result in bird death.

Sfm Fimbriae Play an Important Role in the Pathogenicity of Escherichia coli CE129

Microbiology Research
Avian pathogenic Escherichia coli (APEC) is highly infective in poultry, causing significant economic losses to the poultry industry. As an extraintestinal pathogenic strain, adherence is a critical step in the infection.

IbeR Facilitates Stress-Resistance, Invasion and Pathogenicity of Avian Pathogenic Escherichia coli

PLOS ONE, 2015
Systemic infections by avian pathogenic Escherichia coli (APEC) are economically devastating to poultry industries worldwide. IbeR, located on genomic island GimA, was shown to serve as an RpoS-like regulator in rpoS gene mutation neonatal meningitis E. coli (NMEC) RS218.

Evaluation of Escherichia coli isolates from healthy chickens to determine their potential risk to poultry and human health.

PLoS ONE, 2017
Extraintestinal pathogenic Escherichia coli (ExPEC) strains are important pathogens that cause diverse diseases in humans and poultry. Some E. coli isolates from chicken feces contain ExPEC-associated virulence genes, so appear potentially pathogenic ...
