Characterization of Rosculus vilicus sp. nov., a rhizarian amoeba interacting with Mycobacterium avium subsp. paratuberculosis [PDF]

Frontiers in Microbiology, 2023
Free-living amoebae are described as potential reservoirs for pathogenic bacteria in the environment. It has been hypothesized that this might be the case for Mycobacterium avium subsp. paratuberculosis, the bacterium responsible for paratuberculosis. In

Diagnosis of Paratuberculosis in Histopathological Images Based on Explainable Artificial Intelligence and Deep Learning [PDF]

Traitement du Signal, Vol. 39, No. 3, pp. 863-869, 2022, 2022
Artificial intelligence holds great promise in medical imaging, especially histopathological imaging. However, artificial intelligence algorithms cannot fully explain the thought processes during decision-making. This situation has brought the problem of explainability, i.e., the black box problem, of artificial intelligence applications to the agenda:

The role of microbiota and its modulation in colonic diverticular disease

Neurogastroenterology &Motility, Volume 35, Issue 12, December 2023., 2023
Abstract Background Diverticular disease (DD) is a common condition in Western countries. The role of microbiota in the pathogenesis of DD and its related symptoms has been frequently postulated since most complications of this disease are bacteria‐driven and most therapies rely on microbiota modulation.

Current status of nano‐vaccinology in veterinary medicine science

Veterinary Medicine and Science, Volume 9, Issue 5, Page 2294-2308, September 2023., 2023
Nanovaccines are successful because of the enhanced lowest immunotoxicity, antigen stability, better immunogenicity, the flexibility of the physical characteristics of nanomaterials and sustained release. Abstract Vaccination programmes provide a safe, effective and cost‐efficient strategy for maintaining population health.

Expert opinion on the identification, risk assessment, and mitigation of microorganisms and parasites relevant to xenotransplantation products from pigs

Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023
Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...

Phylogenetic distribution of malonate semialdehyde decarboxylase (MSAD) genes among strains within the genus Mycobacterium: evidence of MSAD gene loss in the evolution of pathogenic mycobacteria

Frontiers in Microbiology, 2023
Despite the great diversity of malonate semialdehyde decarboxylases (MSADs), one of five subgroups of the tautomerase superfamily (TSF) found throughout the biosphere, their distribution among strains within the genus Mycobacterium remains unknown.

What is the scope for existing (including recently developed) diagnostic methods to detect infected cattle which are not currently detected by the existing programme?

Food Risk Assess Europe, Volume 1, Issue 2, September‐December 2023., 2023
Abstract This document critically reviews the range of diagnostic methods currently employed in Ireland to detect animals infected with Mycobacterium bovis, the causative agent of bovine tuberculosis (bTB), that are not currently detected by the existing eradication programme.

Differences in skin test reactions to official and defined antigens in guinea pigs exposed to non-tuberculous and tuberculous bacteria

Scientific Reports, 2023
The single and comparative intradermal tuberculin tests (SITT and CITT) are official in vivo tests for bovine tuberculosis (TB) diagnosis using bovine and avian purified protein derivatives (PPD-B and PPD-A).
