Fig. 7From: Development of an indirect ELISA, blocking ELISA, fluorescent microsphere immunoassay and fluorescent focus neutralization assay for serologic evaluation of exposure to North American strains of Porcine Epidemic Diarrhea VirusAssessment of neutralizing antibody titers in different sample matrices following PEDV exposure. FFN titers were detected in various sample matrices including colostrum (n = 25), milk (n = 23) and serum (n = 27) collected at the time of farrowing and weekly for two weeks post-farrowing. Error bars indicate a 95 % confident interval for mean titers indicated by horizontal linesBack to article page
