Oxidative costs of migration: infections as an added burden

Journal of Avian Biology, Volume 2026, Issue 2, March 2026.
There is increasing evidence that over‐production of reactive species (RS) constitutes a significant physiological cost for migrating birds. The current view entails that RS during migration originate primarily from increased metabolic activity associated with prolonged flights and refueling.

Complement Hyperactivation Is Mediated by Alternative and Lectin Pathways During Early Phase of Severe Vaccination‐Omicron BA.5 Infection

Journal of Medical Virology, Volume 98, Issue 3, March 2026.
ABSTRACT Complement temporal activation kinetics, activation pathways, and their relationship with thromboinflammation and antibody responses in severe vaccination‐COVID‐19 remains unclear. Based on a vaccinated‐infected cohort, we analyzed complement immune responses across mild to critical COVID‐19 cases by a dynamic model.

Chicken Origin Tribasic H9N2 Avian Influenza Virus Induces Potent Early Antiviral Response With Low Pathogenicity in Japanese Quails

Veterinary Medicine and Science, Volume 12, Issue 2, March 2026.
This study gives valuable insights into host–pathogen interaction and confirms that the circulating tribasic H9N2 virus remains phenotypically low pathogenic in Japanese quails in Bangladesh but cause long‐term impairment of important productivity parameters (weight gain, laying rates).

Lack of H5N1 Avian Influenza Transmission to Hospital Employees, Hanoi, 2004

Emerging Infectious Diseases, 2005
To establish whether human-to-human transmission of influenza A H5N1 occurred in the healthcare setting in Vietnam, we conducted a cross-sectional seroprevalence survey among hospital employees exposed to 4 confirmed and 1 probable H5N1 case-patients or ...
