Determining an optimal pool size for testing beef herds for Johne’s disease in Australia [PDF]
PLoS One, 2019 Bovine Johne’s disease (JD) is a chronic debilitating disease affecting cattle breeds worldwide. Pooled faecal samples are routinely tested by culture to detect Mycobacterium avium subsp. paratuberculosis (Mptb) infection.

The development and use of Actiphage® to detect viable mycobacteria from bovine tuberculosis and Johne’s disease‐infected animals [PDF]
Microb Biotechnol, 2019 Here, we describe the development of a method that exploits bacteriophage D29 as a lysis agent for efficient DNA extraction from low numbers of mycobacterial cells. This method (Actiphage®) used in combination with PCR achieved rapid and sensitive (LOD ≤

Biomarkers for Early Stages of Johne’s Disease Infection and Immunization in Goats [PDF]
Front Microbiol, 2018 Background: Mycobacterium avium subsp. paratuberculosis (M. paratuberculosis) is the causative agent of Johne’s disease, a chronic enteric infection of ruminants. Infection occurs within the first few months of life but remains subclinical for an average

Failure to detect M. avium subspecies paratuberculosis in Johne’s disease using a proprietary fluorescent in situ hybridization assay [PDF]
BMC Research Notes, 2018 Objectives Mycobacterium avium subspecies paratuberculosis (MAP) causes Johne’s disease in ruminants. The “gold standard” of MAP detection is by culture, DNA sequencing possibly supplemented by identification of Ziehl–Neelsen positive mycobacteria.

Johne's Disease in Dairy Cattle: An Immunogenetic Perspective
Frontiers in Veterinary Science, 2021 Johne's disease (JD), also known as paratuberculosis, is a severe production-limiting disease with significant economic and welfare implications for the global cattle industry. Caused by infection with Mycobacterium avium subspecies paratuberculosis (MAP)
