Mycobacterium bovis Induces Endoplasmic Reticulum Stress Mediated-Apoptosis by Activating IRF3 in a Murine Macrophage Cell Line

Frontiers in Cellular and Infection Microbiology, 2016
Mycobacterium bovis (M. bovis) is highly adapted to macrophages and has developed multiple mechanisms to resist intracellular assaults. However, the host cells in turn deploy a multipronged defense mechanism to control bacterial infection.

Forging a New Frontier: Antimicrobial Peptides and Nanotechnology Converging to Conquer Gastrointestinal Pathogens

Small, Volume 21, Issue 26, July 3, 2025.
This review explores the potential of antimicrobial peptides (AMPs) and nanotechnology for the treatment of gastrointestinal infections. It analyzes bacterial resistance mechanisms, the antimicrobial actions of AMPs, and advances in nanocarriers, such as lipid‐based, polymeric, metallic, and mesoporous silica systems, that enhance peptide protection ...

Cryopreservation of Mycobacterium bovis isolates

Semina: Ciências Agrárias, 2016
Research, development of new biotechnological methods, diagnostic tests, confirmation of results, and reinvestigations are possible because of the availability of well-preserved living organisms maintained without any changes. Cryopreservation is a simpler, more reliable and long-term stable method for culture maintenance.

Assessment of Risk Factors Related to Environmental Factors and Herd Management for Bovine Respiratory Syncytial Virus and Bovine Parainfluenza Virus‐3 Infections Frequently Observed in Beef and Dairy Cattle

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
In this study, molecular diagnosis of BRSV and BPIV3 factors was aimed and risk factors were tried to be determined by considering ‘environmental factors’, ‘herd management factors’ and ‘infection‐related factors.’ RT‐PCR technique was used for the molecular detection of pathogens and multivariate and univariate statistical analyses were performed ...

Evaluating the Effects of 60°C Heating for 90 Min on Bacterial Pathogen Viability and IgG Concentration in Bovine Colostrum

Veterinary Medicine and Science, Volume 11, Issue 4, July 2025.
Heating bovine colostrum at 60°C for up to 90 min eliminates key pathogens, including Escherichia coli, Salmonella Enteritidis, Mycobacterium avium subsp. paratuberculosis and Mycobacterium avium subsp. avium, while preserving IgG levels. This protocol ensures microbial safety and colostrum quality, offering a practical solution for dairy herd health ...

White‐tailed deer habitat use and implications for chronic wasting disease transmission Uso del hábitat del ciervo de cola blanca e implicaciones para la transmisión de la caquexia crónica

Wildlife Monographs, Volume 217, Issue 1, July 2025.
White‐tailed deer habitat use, activity, and attraction to conspecifics is highly variable between sexes and seasons. In this study, we leverage an unprecedented dataset from Wisconsin to illustrate how deer respond to changing physiological and social needs through the course of year.
