Currently, no fast diagnosis method exists for COVID-19 infections that are likely to be fatal. This perspective proposes the use of nanobased technologies,

A study was conducted to develop a cross-protective epitope-based vaccine against Actinobacillus pleuropneumoniae (APP), the pathogen causing porcine contagious pleuropneumonia. Six epitopes were selected from the head domain of trimeric autotransporter adhesin and connected to form a recombinant tandem antigen (rta) gene. Mice were immunized with the RTA protein

The study characterizes the Korean variant IBV K40/09 for its immunogenicity and protective efficacy against seven different IBV serotypes. Chickens immunized with IBV K40/09 showed significant protection against all challenge viruses at the trachea and kidney levels, suggesting its potential as a cross-protective vaccine candidate in IBV control strategies.

The study investigated the relationship between Bacillus Calmette–Guérin (BCG) vaccination policies and COVID-19 cases and deaths in various countries. The results showed that countries with universal BCG vaccination policies had significantly fewer COVID-19 cases and deaths per million population compared to those without such policies. The study suggested that BCG may offer protection from COVID-19 through mechanisms such as trained immunity, epigenetic reprogramming, and production of

A study developed two optimized M2e DNA vaccines based on the N-terminal extracellular region of the influenza virus M2 protein for cross-protection against various influenza strains. The vaccines, p-tPA-p3M2e and p-p3M2e, increased antigenic epitope density and enhanced antigen secretion, resulting in high M2e-specific humoral and cellular immune responses in mice

Serum antibodies from individuals recovered from SARS-CoV infection and from animals immunized against SARS-CoV can cross-neutralize SARS-CoV-2, providing insights for developing universal vaccines against emerging coronaviruses. The study found that sera from SARS-CoV patients reacted strongly with SARS-CoV-2 proteins and neutralized both SARS-CoV and SARS-

The NOSO-COR Project is a multicentre, international, prospective observational study aimed at documenting suspected or confirmed cases of nosocomial SARS-CoV2 infection in hospitals in France and those affiliated with the GABRIEL network. Demographic and clinical data will be collected, along with nasopharyngeal swabs for RT-PCR testing. The study will analyze the characteristics of study participants and the proportion of confirmed nosocomial

The passage suggests that obese men with cardiovascular factors experience more severe forms of SARS-CoV-2 infection due to the role of visceral fat in the gut-lymphatics-lung axis. SARS-CoV-2 can infect both respiratory and intestinal epithelial cells, leading to increased intestinal permeability from various factors. This permeability increase allows for the translocation of microbial components
