In this study, piglets delivered from 3 pregnant sows vaccinated with CSF and 2 unvaccinated pregnant sows were used, and the serum CSF neutralizing antibody titeres in piglets with colostral restriction during the suckling period was significantly lower than those without the restriction. In the piglets with restricted colostrum intake, the group with a period from vaccination to parturition of 21 days had a significantly lower CSF antibody titer during the experimental period than the group of more than 161 days. The percentage of piglets testing positive for CSF antibodies was 0% at 14 and 21 days after birth in the group with short a short period (21 days) from vaccination to parturition and colostral restriction. Our results indicate that both of the timing of the initial vaccination of unimmunized pregnant sows and the restriction of colostrum have a clear effect on the level of maternal CSF antibodies in suckling piglets.","PeriodicalId":17329,"journal":{"name":"Journal of the Japan Veterinary Medical Association","volume":"301 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"79710357","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was conducted to understand the transmissibility of classical swine fever virus in wild boar populations, limited by the impossibility of a correct case count because of the nature of wildlife. Wildlife PCR test results between September 2018 and February 2019 were collected from the homepages of Gifu, Aichi, and Mie Prefectures. In descriptive epidemiology, the geographical spread in the three prefectures, and temporal patterns of PCR test positivity in Gifu Prefecture were observed. Using the Susceptible ( S ) - Exposed ( E ) - Infectious ( I ) - Recovery ( R ) model, assuming the weekly test positivity fol-lows beta distribution, parameters were estimated in a Markov Chain Monte Carlo simulation, and the basic reproduction number ( R 0 ) was calculated. As a result, the mean infectious period was as long as 100 - 145 days, and R 0 was estimated to be 4.2 - 5.1. In this analysis, however, population dynamics considering births and deaths and population density were not considered. In the future, a more detailed study based on wild boar field data is necessary.","PeriodicalId":17329,"journal":{"name":"Journal of the Japan Veterinary Medical Association","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73724293","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
