The aim of this study is to evaluate the microbiological contamination and antimicrobial resistance of Salmonella in Shanghai, providing references for supervision over food safety and clinical treatment. This study analysed the distribution of serotypes, the distribution of antimicrobial resistance in different poultry meats and serotype of Salmonella, the correlation between different antimicrobial resistance, and multiple drug resistance (MDR) of 139 strains of Salmonella from poultry meats. The results showed that the proportion of Salmonella detected in pigeons was high, which could cause severe diseases to humans. The most common resistance was observed to TET (about 60%), and resistance was even found to IPM. Resistance to two or more antimicrobials was accounted for 75.5%, indicating a wide spreading MDR.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47480889","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thus, IgE epitopes could be as key targets for precise αS1-CN detection and allergenicity assessment. Here, we designed a tandem containing nine IgE linear epitopes of αS1-CN (tαS1-CN), expressed the recombinant tαS1-CN in Escherichia coli, and prepared the rabbit polyclonal antibody against recombinant tαS1-CN (pAb-tαS1-CN). The obtained recombinant tαS1-CN had a purity of 94.43% and retained the antigenicity and potential allergenicity of IgE epitopes. The pAb-tαS1-CN could recognize the nine IgE epitopes of αS1-CN, and also showed high specificity. The ability of pAb-tαS1-CN to evaluate the potential allergenicity of milk in foods was validated by sera from cow's milk allergy patients. These findings indicate that our prepared pAb-tαS1-CN may represents a valuable tool for the evaluation of milk allergenicity in processed foods.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-06-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"43287676","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To understand the molecular role of viridicatol in stabilising mast cells, transcriptomes of viridicatol-treated RBL-2H3 cells were analysed by RNA-sequencing. There were 128 differentially expressed genes in activated RBL-2H3 cells with or without viridicatol treatment. The mast cell activation-related genes were significantly reduced by treatment with viridicatol through RT-qPCR analysis. Moreover, Kyoto Encyclopedia of Genes and Genomes enrichment analysis indicated that viridicatol was important in mast cell stabilisation by affecting MAPK and JAK-STAT signalling pathways. Additionally, molecular docking and western blot analysis revealed that the phosphorylated JNK, ERK, P38, and STAT6 proteins were inhibited by viridicatol. Taken together, viridicatol has the potential to be used as a new type of anti-food allergic functional material via controlling MAPK and JAK-STAT signalling pathways of mast cells.","PeriodicalId":12300,"journal":{"name":"Food and Agricultural Immunology","volume":" ","pages":""},"PeriodicalIF":3.0,"publicationDate":"2023-05-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"41962549","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
