Recombinant invasive Lactobacillus plantarum expressing the J subgroup avian leukosis virus Gp85 protein induces protection against avian leukosis in chickens

Establishment and application of a gold nanoparticle-based immunochromatographic test strip for the detection of avian leukosis virus P27 antigen in egg white samples

“…4,5 Based on the antigen structure, host category, and mutual interference between different strains of the virus envelope glycoprotein, ALV can be divided into 11 sub-groups A-K, with subgroup J (ALV-J) causing the greatest harm and causing incalculable losses to the global poultry industry. 6,7 The coding region of ALV contains three coding genes: gag, pol, and env and ALV-P27 exists in the gag gene and has high homology and conservation in various ALV subgroups. 8,9 The translated P27 protein is the core protein of the virus and the main antigen component for the immunological detection of ALV selection.…”

Mechanism of Lactiplantibacillus plantarum regulating Ca2+ affecting the replication of PEDV in small intestinal epithelial cells

“…In recent years, research has shown that a variety of probiotics can maintain microbial homeostasis in the intestinal environment and prevent diarrhea ( Hu et al, 2022 ; Liang et al, 2023 ). Antiviral research into probiotics and their metabolites has also become a hot topic ( Leblanc et al, 2022 ; Liu et al, 2022 ) Lactiplantibacillus plantarum (Lp) significantly reduced the cytopathic effects of respiratory syncytial virus (RSV), influenza B virus, and HCoV-229E coronavirus ( Spacova et al, 2023 ). Lp is a gram-positive facultative anaerobic bacterium that is widely found in nature, is commonly found in various fermented foods, and is one of the important flora of the gut microbiota.…”
