Thoracic Ultrasonography Findings and Their Association With Respiratory Pathogens in 221 Young Beef Cattle at Fattening Farms: A Cross‐Sectional Study

Journal of Veterinary Internal Medicine, Volume 39, Issue 4, July/August 2025.
ABSTRACT Background Thoracic ultrasonography (TUS) could improve antibiotic treatment selection in cattle with respiratory diseases. Hypothesis/Objectives Evaluate the association between respiratory pathogens and consolidations on TUS in feedlot cattle, at both individual and group levels. Animals A total of 221 bulls, aged 8.8 months and weighing 322.

CoV-RBD121-NP Vaccine Candidate Protects against Symptomatic Disease following SARS-CoV-2 Challenge in K18-hACE2 Mice and Induces Protective Responses That Prevent COVID-19-Associated Immunopathology

Vaccines, 2021
We developed a SARS-CoV-2 vaccine candidate (CoV-RBD121-NP) comprised of a tobacco mosaic virus-like nanoparticle conjugated to the receptor-binding domain of the spike glycoprotein of SARS-CoV-2 fused to a human IgG1 Fc domain.

Organic Transistor‐Based Biosensors for Viral RNA Detection and Variant Monitoring: From SARS‐CoV‐2 to Effective Management of Future Pandemics

Advanced Sensor Research, Volume 4, Issue 6, June 2025.
A novel approach for direct sensing of viral RNA is proposed, allowing PCR‐free detection of viral RNA from genomic material, and variants screening by discrimination of polymorphic amplicons. The device is a cost‐effective, user‐friendly platform suitable for both mass screening kits and as a laboratory tool for an optimized management of resources ...

Multiple Early Introductions of SARS-CoV-2 to Cape Town, South Africa

Viruses, 2021
Cape Town was the first city in South Africa to experience the full impact of the coronavirus disease 2019 (COVID-19) pandemic. We acquired samples from all suspected cases and their contacts during the first month of the pandemic from Tygerberg Hospital.

Identification of potential SARS‐CoV‐2 genomic regions representing hallmarks for adaptation to different hosts

iMetaOmics, Volume 2, Issue 2, June 2025.
The k‐mer‐based pipeline, namely the Pathogen Origin Recognition Tool using Enriched K‐mers (PORT‐EK) identifies genomic regions enriched in the respective hosts after the comparison of multi‐genomes of isolates between different host species. The enriched k‐mer counts, which may serve as a potential marker, enable the classification and prediction of ...

Optimization of Structure‐Guided Development of Chemical Probes for the Pseudoknot RNA of the Frameshift Element in SARS‐CoV‐2

Angewandte Chemie, Volume 137, Issue 9, February 24, 2025.
The SARS‐CoV‐2 frameshift element pseudoknot plays a crucial role in viral replication. Using various techniques, especially NMR spectroscopy and in vitro frameshift assays, we have developed and optimized chemical probes that serve as fundamental structures for potential inhibitors targeting viral RNAs.

Phylogenetic Study of 2019-nCoV by Using Alignment Free Method (Evolutionary Bifurcation of Novel Coronavirus Mutants) [PDF]

arXiv, 2020
The phylogenetic tree of SARS-CoV-2 (nCov-19) viruses is reconstructed according to the similarity of genome sequences. The tree topology of Betacoronavirus is remarkably consistent with biologist's systematics. Because the tree construction contains enough information about virus mutants, it is suitable to study the evolutionary relationship between ...

Land Use Change and Infectious Disease Emergence

Reviews of Geophysics, Volume 63, Issue 2, June 2025.
Abstract Major infectious diseases threatening human health are transmitted to people from animals or by arthropod vectors such as insects. In recent decades, disease outbreaks have become more common, especially in tropical regions, including new and emerging infections that were previously undetected or unknown. Even though there is growing awareness
