Dual-Engineered Phage Vaccine Platform Facilitates STING Activation for Influenza Protection.

Influenza epidemics remain a global public health challenge. Vaccination with nucleic acid-based vaccines, which trigger strong cellular and humoral immune responses, represents a promising approach for preventing virus infection. However, its effectiveness relies on efficient delivery and an immunoadjuvant.

Cuttlefish ink-derived melanin nanoparticle-embedded tremella fuciformis polysaccharide hydrogels for the treatment of MRSA-infected diabetic wounds.

Diabetic wounds arise great attention as they are difficult to heal and easily suffer from serious bacterial infection. However, the overuse of antibiotics increases the resistance of bacteria and makes common drugs ineffective. Here, we developed a photothermal hydrogel (TFP/NP) composed of tremella fuciformis polysaccharides (TFPs) and cuttlefish ink-derived melanin nanoparticles (NPs).

Characterization of an Escherichia coli phage Tequatrovirus YZ2 and its application in bacterial wound infection.

The increasing prevalence of drug-resistant Escherichia coli (E. coli) resulting from the excessive utilization of antibiotics necessitates the immediate exploration of alternative approaches to counteract pathogenic E. coli.

Self-Assembled Virus-Like Particle Vaccines via Fluorophilic Interactions Enable Infection Mimicry and Immune Protection.

Influenza epidemics persistently threaten global health. Vaccines based on virus-like particles (VLPs), which resemble the native conformation of viruses, have emerged as vaccine candidates. However, the production of VLPs via genetic engineering remains constrained by challenges such as low yields, high costs, and being time consuming.

Structure of infective Getah virus at 2.8 Å resolution determined by cryo-electron microscopy.

Getah virus (GETV), a member of the genus alphavirus, is a mosquito-borne pathogen that can cause pyrexia and reproductive losses in animals. Although antibodies to GETV have been found in over 10% of healthy people, there are no reports of clinical symptoms associated with GETV. The biological and pathological properties of GETV are largely unknown and antiviral or vaccine treatments against GETV are still unavailable due to a lack of knowledge of the structure of the GETV virion.

Development and application of SYBR Green Ⅰ real-time quantitative reverse transcription PCR assay for detection of swine Getah virus.

Getah virus (GETV), a mosquito-borne virus belonging to the Alphavirus genus of family Togaviridae, has become increasingly problematic, which poses a huge threat to the safety of animals and public health. In order to detect GETV quickly and accurately, we have developed a SYBR Green I real-time quantitative reverse transcription PCR (RT-qPCR) assay for GETV with the detection limit of 66 copies/μL, excellent correlation coefficient (R) of 0.9975, and amplification efficiency (E) of 98.

The role of GtxA during Gallibacterium anatis infection of primary chicken oviduct epithelial cells.

Gallibacterium anatis (G. anatis), one of the major pathogens causing reproductive tract disorders in laying hens, leads to a reduction in egg production and increased mortality, caused by either single or mixed infections with other pathogens. As a specific virulence factor of G.
