Failure to detect M. avium subspecies paratuberculosis in Johne’s disease using a proprietary fluorescent in situ hybridization assay

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.

Innate immune markers that distinguish red deer (Cervus elaphus) selected for resistant or susceptible genotypes for Johne’s disease

Veterinary Research, 2013
While many factors contribute to resistance and susceptibility to infectious disease, a major component is the genotype of the host and the way in which it is expressed.

A national serosurvey to determine the prevalence of paratuberculosis in cattle in Bhutan following detection of clinical cases

Veterinary Medicine and Science, 2018
Johne's disease is an economically important ruminant disease predominantly affecting cattle, sheep and goats. The economic losses are due to early culling, reduced growth rate, progressive weight loss and reduced production.

Mycobacterium avium Subsp. paratuberculosis and Human Endogenous Retrovirus in Italian Patients With Inflammatory Bowel Disease (IBD) and Irritable Bowel Syndrome (IBS)

Immunology, Volume 178, Issue 3, Page 417-427, July 2026.
Inflammatory bowel disease (IBD), comprising ulcerative colitis (UC) and Crohn's disease (CD), is a recognised gastrointestinal disorder. Mycobacterium avium subspecies paratuberculosis (MAP) is implicated in IBD pathogenesis. Persistent exposure and active infections by MAP may contribute to the unsilencing of human endogenous retroviruses (HERV ...

Foodborne Risk to Human Health of Hepatitis E Virus in Pigs and Pigmeat in Ireland

Food Risk Assess Europe, Volume 4, Issue 3, July 2026.
Abstract Hepatitis E virus (HEV) is a major cause of acute viral hepatitis in people worldwide. In Ireland, evidence of past HEV exposure has been identified in approximately 5% of blood donors, while a small proportion have detectable viral RNA. HEV is also present in pigs and has been detected in pigmeat products, raising concerns about foodborne ...
