Research on bulk tank analysis for Johne’s Disease presented

AntelBio presented data on analysis of bulk tank samples for Johne’s infection at recent JDIP meetings. The convenience of bulk tank sample collection and the rapid turnover of the ELISA assay offer an attractive mechanism to evaluate dairy herds for the presence of Johne’s. Bulk milk samples from 515 farms were analyzed to investigate if milk testing can be employed to detect Johne’s disease. Results indicate that analysis by bulk milk ELISA and/or real-time PCR assay correlated closely with environmental fecal analysis. Additionally, the results from the real-time PCR assay indicate that shedding Johne’s causative organism and/or contamination of milk on US dairies (31.3% of samples) may be a more frequent occurrence than previously recognized, suggesting additional efforts to evaluate the quality of the milk supply are warranted.

Salmonella dublin testing evaluated

AntelBio is currently collaborating with a WI veterinary clinic to evaluate effectiveness of an antibody ELISA for Salmonella dublin in blood and milk samples. Successful development of an assay for this complex infection could provide not previously available insight into Salmonella dublin infections that can potentially cause severe human infection. Watch for more as work continues.
