Serology and culture based MAP prevalence on three RDQMA farms. Prevalence of MAP in all samples collected throughout a 10 year follow-up study in three dairy farms in New York, Pennsylvania and Vermont. Prevalence in three farms and overall prevalence are shown. Prevalence of MAP in serum samples is measured through ELISA, prevalence in fecal samples is measured using MAP culture methods, prevalence in tissues, collected at slaughter, is measured through culture of four tissues samples.
