Performance of Subgenomic RT‐PCR for Predicting SARS‐CoV‐2 Infectivity Compared to Genomic RT‐PCR and Culture Isolation

Journal of Medical Virology, Volume 97, Issue 5, May 2025.
ABSTRACT SARS‐CoV‐2 clinical samples can be detected as positive for a long period of time using real‐time RT‐PCR, even when patients are no longer infectious. Viral culture is the gold standard for assessing a patient's infectivity, but it is a time‐consuming technique and lacks sensitivity. SARS‐CoV‐2 subgenomic RNA (sgRNA) detection has been used as

Predicting COVID-19 distribution in Mexico through a discrete and time-dependent Markov chain and an SIR-like model [PDF]

arXiv, 2020
COVID-19 is an emergent viral infection which rose in December 2019 in a city in the Chinese province of Hubei, Wuhan; the viral aetiology of this infection is now known as COVID-19 virus, which belongs to the Betacoronavirus genus. This virus produces the syndrome of acute respiratory stress that h as been witnessed in other coronaviruses, such as ...

Novel Trispecific Neutralizing Antibodies With Enhanced Potency and Breadth Against Pan‐Sarbecoviruses

MedComm, Volume 6, Issue 5, May 2025.
Multispecific antibodies harness the advantages of two or more mAbs. In this study, we designed novel trispecific antibodies, Tri‐1 and Tri‐2, derived from our previously identified mAbs, PW5‐5, PW5‐535, and PW5‐570. These trispecific antibodies exhibited enhanced binding affinity and broad neutralization capacity against SARS‐CoV, SARS‐CoV‐2 variants,

Femtomolar-level detection of SARS-CoV-2 spike proteins using toroidal plasmonic metasensors [PDF]

arXiv, 2020
Effective and efficient management of human betacoronavirus severe acute respiratory syndrome (SARS)-CoV-2 infection i.e., COVID-19 pandemic, required sensitive sensors with short sample-to-result durations for performing diagnostics. In this direction, one of appropriate alternative approach to detect SARS-CoV-2 at low level (fmol) is exploring ...

Synergistic Inactivation of Airborne Viruses by Low‐Concentration Ozone With High Humidity and Temperature

Microbiology and Immunology, Volume 69, Issue 5, Page 280-288, May 2025.
ABSTRACT Ambient humidity, temperature, and ozone influence the viability of airborne viruses, but their synergistic effects are poorly understood, particularly regarding ozone with humidity/temperature changes. Therefore, we examined the inactivation of airborne influenza viruses and coronaviruses under combinations of low ambient ozone concentrations,

Myeloid‐Driven Immune Suppression Subverts Neutralizing Antibodies and T Cell Immunity in Severe COVID‐19

Journal of Medical Virology, Volume 97, Issue 4, April 2025.
ABSTRACT The objective of this study was to better understand immune failure mechanisms during severe acute respiratory syndrome coronavirus 2, SARS‐CoV‐2 infection, which are critical for developing targeted vaccines and effective treatments. We collected 34 cases representing different disease severities and performed high‐quality single‐cell TCR/BCR

Opinion and report of the French Agency for Food, Environmental and Occupational Health & Safety (ANSES) on the assessment of the impact of fox population dynamics on public health

Food Risk Assess Europe, Volume 3, Issue 2, April 2025.
ABSTRACT The Red Fox (Vulpes vulpes) can be hunted as a game species. It may also be listed as a “species likely to cause damage” (ESOD – the acronym in French), for public health reasons among others. Conversely, benefits linked to the presence of foxes are also put forward, such as the predation of rodents carrying zoonotic agents.
