Much effort has been made to develop a vaccine for the prevention of SE colonization and infection in poultry. However, the effect of inactivated whole-cell SE vaccines on the bacterial attachment has not been clarified. This study investigated the immune responses to a killed whole-cell SE vaccine in chickens and the effect of vaccination on the bacterial attachment of SE to cultured Vero cells. A 1 ml dose of 108-109 CFU viable SE bacterial cells was orally administered to chickens at 4 weeks or 10 months post vaccination. The number (CFU) of SE in 1 g of cecal droppings was counted on day 6 after administration. The SE CFUs were significantly lower (p < 0.05) in the vaccinated chickens, not only at 4 weeks but also at 10 months after vaccination, than in the unvaccinated control chickens. Anti-SE IgG and anti-SE IgA were detected using enzyme-linked immunosorbent assay (ELISA) in serum and intestinal and oviduct fluid samples from vaccinated chickens. Adhesion of heat-killed SE cells to Vero cells was reduced by pre-treatment of the bacteria by the vaccinated chicken-derived intestinal fluid, indicating the potential of the vaccine-induced antibody to prevent SE adhesion to epithelial cell surfaces.","PeriodicalId":73044,"journal":{"name":"Food safety (Tokyo, Japan)","volume":"6 4","pages":"151-155"},"PeriodicalIF":0.0,"publicationDate":"2018-11-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6795388/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37591540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Major adverse effects of desmedipham were suppressed body weight, hemolytic anemia, methemoglobinemia and follicular cell hypertrophy in thyroid. Neither carcinogenicity, reproductive toxicity, nor genotoxicity relevant to human health was observed on desmedipham. Desmedipham, at the dose with maternal toxicity, caused external anomalies such as mandibular malformation and cleft palate, visceral anomalies such as ventricular septum defect, and skeletal anomalies such as defect of sternum and asymmetric alignment of seternebral hemicentres in developmental toxicity studies in rats. No teratogenetic effects were observed in rabbits.

In an 18-month chronic toxicity/carcinogenicity study in mice, increased incidences of hepatocellular adenomas and carcinomas were observed in females in the 500 ppm group. In spite of a recent experiment implying the possible indirect genotoxicity of dicyclanil on the carcinogenicity, dicyclanil is unlikely to exert the carcinogenicity in vivo through the genotoxic mechanism judging from other studies. FSCJ recognized it as feasible to set the threshold value. Adverse effects detected at the lowest dose in various toxicological studies were the increased plasma levels of cholesterol and phospholipid at 100 ppm (equivalent to 2.7 mg/kg bw/day in males and 3.5 mg/kg bw/day in females) in a 90-day subacute toxicity study in dogs. No-observed-adverse-effect level (NOAEL) of this study was 20 ppm (equivalent to 0.61 mg/kg bw/day in males and 0.71 mg/kg bw/day in females). On the other hand, the NOAEL in a long term study, a 12-month chronic toxicity study in dogs was 25 ppm (equivalent to 0.71 mg/kg bw/day in males) based on increased level of plasma cholesterol observed only in males at 150 ppm (equivalent to 4.4 mg/kg bw/day in males and 5.1 mg/kg bw/day in females). The increased cholesterol levels in plasma were common in both studies in dogs. It was appropriate to choose the NOAEL for the effect on cholesterol in the longer term treatment, and thus FSCJ adopted the NOAEL of 0.71 mg/kg bw/day. Consequently, FSCJ specified the ADI of 0.0071 mg/kg bw/day for dicyclanil based on the NOAEL of 0.71 mg/kg bw/day in the 12-month chronic toxicity study in dogs, by applying a safety factor of 100.","PeriodicalId":73044,"journal":{"name":"Food safety (Tokyo, Japan)","volume":"6 3","pages":"136-138"},"PeriodicalIF":0.0,"publicationDate":"2018-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC7004925/pdf/foodsafetyfscj-6-136.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"37627779","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
