Update of the list of QPS‐recommended biological agents intentionally added to food or feeds as notified to EFSA

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract The qualified presumption of safety (QPS) process was developed to provide a harmonised safety assessment approach to support EFSA Scientific Panels and Units. The QPS approach assesses the taxonomic identity, body of relevant knowledge and safety concerns of microorganisms intentionally added to the food and feed chain.

Baculovirus Per Os Infectivity Factors Form a Complex on the Surface of Occlusion-Derived Virus [PDF]

, 2010
Five highly conserved per os infectivity factors, PIF1, PIF2, PIF3, PIF4, and P74, have been reported to be essential for oral infectivity of baculovirus occlusion-derived virus (ODV) in insect larvae.

Unveiling Origin Pitfalls in Metagenomic Surveillance for Emerging Infectious Diseases: Parvoviruses as a Model

iMetaMed, Volume 1, Issue 1, September 2025.
A diverse reagent‐associated virome, including parvoviruses, misleads zoonotic surveillance. By leveraging large language models (ChatGPT‐4o), we construct a virus discovery data framework (PVDDC) and ParvoDB to access and correct host misattributions, thereby enhancing the accuracy of metagenomic surveillance for emerging zoonotic diseases.

Update of the list of qualified presumption of safety (QPS) recommended microbiological agents intentionally added to food or feed as notified to EFSA 22: Suitability of taxonomic units notified to EFSA until March 2025

EFSA Journal, Volume 23, Issue 7, July 2025.
Abstract The qualified presumption of safety (QPS) process was developed to assess the safety of microorganisms used in food and feed chains. During the period covered by this Statement, no new information warranted changes to the status of previously recommended QPS taxonomic units.

Analysis of the Complete Genome Sequence of the Hz-1 Virus Suggests that It Is Related to Members of the Baculoviridae [PDF]

Journal of Virology, 2002
ABSTRACT We report the complete sequence of a large rod-shaped DNA virus, called the Hz-1 virus. This virus persistently infects the Heliothis zea cell lines. The Hz-1 virus has a double-stranded circular DNA genome of 228,089 bp encoding 154 open reading frames (ORFs) and also expresses a persistence ...

Honey Bee Viromes From Varroa destructor‐Resistant and Susceptible Colonies

Environmental Microbiology Reports, Volume 17, Issue 3, June 2025.
Our study reveals seasonal variations in honey bee virome composition among colonies independent of their Varroa destructor susceptibility. We report the first detection of AmFV and LSV in Uruguay, obtaining complete or partial genomes of multiple viruses.
