Detection of Mycobacterium paratuberculosis in raw cow’s milk using polymerase chain reaction (PCR) technique [PDF]

Iraqi Journal of Veterinary Sciences, 2020
Paratuberculosis or Johne’s disease is a chronic debilitating disease mainly infects ruminants and caused by Mycobacterium paratuberculosis. Previous serological studies in Mosul city confirm the presence of positive reactants for paratuberculosis in ...

Development of a Fully Automated, High‐Throughput Molecular Assay for Detection of Rat Hepatitis E Virus in Routine Diagnostics

Journal of Medical Virology, Volume 98, Issue 2, February 2026.
ABSTRACT Recently, cases of human infection with rat hepatitis E virus (ratHEV, Rocahepevirus ratti) have been reported worldwide. Due to the significant genetic differences between ratHEV and human HEV genotypes 1–4 (Paslahepevirus balayani), current HEV diagnostic assays are unable to detect ratHEV.

Mycobacteriophage Mcgavigan Uses Noncanonical Bxb1‐Like Repressor for Heterotypic Superinfection Immunity

Journal of Basic Microbiology, Volume 66, Issue 1, January 2026.
ABSTRACT Mycobacteriophage Mcgavigan could be a promising candidate for use as a preventative agent against infections with Mycobacterium avium subsp. paratuberculosis. Bioinformatic analysis of the Mcgavigan genome revealed the presence of an operon containing a “Bxb1‐like” repressor.

Comparison of Machine Learning Tree-Based Algorithms to Predict Future Paratuberculosis ELISA Results Using Repeat Milk Tests

Animals
Machine learning algorithms have been applied to various animal husbandry and veterinary-related problems; however, its use in Johne’s disease diagnosis and control is still in its infancy. The following proof-of-concept study explores the application of

Epigenetic Modifications Influence Reproductive Traits in Small Ruminants

Veterinary Medicine International, Volume 2026, Issue 1, 2026.
The epigenome undergoes dynamic changes shaped by the intricate interplay of genetic and environmental factors, which are crucial for individual growth and development. Recent studies suggest that factors such as nutrition, thermal stress (TS), infections, and assisted reproductive technologies (ARTs) can influence epigenetic changes in small ruminants

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.

An Update on Bioactive Lipids: Fatty Acid Esters of Hydroxy Fatty Acids in Food

Food Chemistry International, Volume 1, Issue 4, Page 366-374, December 2025.
This review focused on the dietary sources, bioavailability, and health benefits of fatty acid esters of hydroxy fatty acids (FAHFAs), emphasizing their potential as functional foods. Understanding FAHFAs in food can help develop targeted functional foods and explore their role in human health, including antidiabetic and anti‐inflammatory effects ...

A holistic approach to colostrum management: Enrichment of maternal colostrum combined with extended colostrum feeding as control measures for bovine rotavirus‐associated neonatal calf diarrhoea

Veterinary Record Case Reports, Volume 13, Issue 4, December 2025.
Abstract Bovine rotavirus A (BRV‐A) genotype G6P11 was identified as a cause of neonatal calf diarrhoea (NCD) in a 600‐cow autumn block calving herd. Dry cows were vaccinated prior to calving. Calf faecal sample (n = 6) microbiology from calves 8‒21 days of age identified BRV‐A.
