Bayesian Estimation of True Prevalence and Associated Risk Factors for Leptospira spp. Among Slaughterhouse Workers and Slaughtered Cattle in the Bahr El Ghazal Region of South Sudan

Zoonoses and Public Health, Volume 73, Issue 3, Page 181-190, May 2026.
ABSTRACT Introduction Leptospirosis is a major but under‐reported zoonotic disease, and epidemiological data from South Sudan remain limited. This study estimated the true prevalence of Leptospira spp. exposure and identified associated risk factors among slaughterhouse workers and slaughtered cattle in Western Bahr El Ghazal. Methods A cross‐sectional

Serial and Parallel Testing Strategies for Johne's Disease: Effects on Milk Production Traits and Milk Income on New Zealand Dairy Cattle

New Zealand Journal of Agricultural Research, Volume 69, Issue 2, April 2026.
The suboptimal accuracy of current diagnostic tests necessitates alternative testing strategies to improve the detection of Johne's disease. We studied parallel and serial testing strategies to quantify the association between milk production and Johne's disease status. For this, two commercial Johne's disease Enzyme‐Linked Immunosorbent Assay, ELISAs,

Deep Learning‐Enabled Engineering of a Hyper‐Stable and Soluble MPB70‐83 Antigen for Sensitive Bovine Tuberculosis Surveillance

Microbial Biotechnology, Volume 19, Issue 4, April 2026.
Schematic representation of the research workflow for the efficient diagnosis of bovine tuberculosis employing peptide fusion proteins. ABSTRACT Bovine tuberculosis (bTB) diagnostics are frequently hindered by the structural instability and insolubility of recombinant multi‐epitope proteins in prokaryotic expression systems.

Comparative Transcriptomic Analysis of Human Macrophages During Mycobacterium avium Versus Mycobacterium tuberculosis Infection

Molecular Microbiology, Volume 125, Issue 3, Page 185-202, March 2026.
Human macrophage transcriptomic responses to Mycobacterium avium (Mav), a major cause of nontuberculous lung disease, were compared to Mycobacterium tuberculosis (Mtb). Both infections activated overlapping immune pathways, including cytokine signaling and GPCRs involved in lipid metabolism, while phospholipases were more strongly regulated by Mav and ...

Microbial‐Immune Interplay in CNS Autoimmune Diseases: Lessons from Animal Models and Clinical Studies

European Journal of Immunology, Volume 56, Issue 2, February 2026.
Mechanism of action of the intestinal microbiota on CNS autoimmune diseases. Environmental factors shape gut microbiota composition; dysbiosis alters microbial metabolites and antigenic signals. These modulate innate and adaptive immunity, affect barrier integrity, and influence CNS‐resident cells such as microglia and astrocytes, contributing to ...

The Relationship Between Immunopathology and Body Condition of Mixed‐Age Ewes

New Zealand Journal of Agricultural Research, Volume 69, Issue 1, February 2026.
Ill thrift in ewes, characterised by less than desirable body condition, is a multifactorial condition often attributed to nutritional deficits, though immunopathological factors may also play a role. This study investigated associations between body condition scores (BCS) and immunopathological states in 120 mixed‐age ewes grazing pasture over 4 ...

Hepatite granulomatosa em bovino causada por Mycobacterium avium subsp. paratuberculosis

Arquivo Brasileiro de Medicina Veterinária e Zootecnia, 2010
Samples from intestines, liver, and lymph nodes were collected from a dairy steer with clinical suspicion of paratuberculosis. The samples were processed for histologic examination with hematoxylin-eosin and Zihel-Neelsen (ZN) staining for the detection ...
