A survey of Free-Living Amoebae (FLAs) in Nasal Mucosa of Healthy Individuals using Culture-based Method

Novelty in Biomedicine, 2021
Free-living amoebas (FLAs) are facultative parasites, and some of them can be highly pathogenic for animals and humans. These protozoan are found in abundance in environmental resources such as freshwater and soil, and thus the possible colonization of ...

Olfactory Tuft Cells Are Critical to Basal Inflammation, Innate Immune Response to Viral Infection, and Modulation of Quiescent Stem Cell Activation, Proliferation and Differentiation

Cell Proliferation, EarlyView.
Olfactory tuft cells communicate with other mucosal cells in maintaining olfactory epithelial immunity and sensory function. Disruption of tuft cell signalling pathways causes a skewed immune response, leading to heightened inflammation and increased activation of the quiescent stem cells, which are further exacerbated by viral infection.

Acanthamoeba encephalitis in immunocompetent hosts: A report of two cases

Journal of Family Medicine and Primary Care, 2020
Acanthamoeba are ubiquitous free-living amoeba. Acanthamoeba infections cause necrotizing vasculitis, resulting in vessel thrombosis and cerebral infarction. Acanthamoeba CNS infections, though uncommon, are associated with high mortality.

The First Report of Cod Gill Poxvirus in Gills of Atlantic Cod (Gadus morhua L.) Suffering From Cardiorespiratory Disease

Journal of Fish Diseases, Volume 48, Issue 4, April 2025.
ABSTRACT Atlantic cod farming experiences renewed growth in Norway, and increased awareness is essential to address emerging diseases in this species. There are few reports on gill diseases in cod, and to date, no viral gill infections of cod have been documented. In this study, we collected samples from three sequential time points in summer 2023 from

Helicobacter pylori In Free‐Living Amoebae: A Potential Environmental Reservoir for Persistence and Transmission [PDF]

Environ Microbiol Rep
Free‐living amoebae may provide an underrecognised environmental niche for Helicobacter pylori, supporting its intracellular persistence, morphological plasticity, and protection from environmental stress. These interactions could facilitate prolonged survival in aquatic and food‐associated environments and contribute to potential waterborne or ...

Beyond single cells: Ten years of commercial lattice light‐sheet microscopy

Journal of Microscopy, EarlyView.
Abstract Lattice light‐sheet microscopy (LLSM) enables gentle, rapid, volumetric fluorescence imaging of living biological systems. The technique employs Bessel beam interference to produce a light‐sheet which retains its thickness over a relatively large field‐of‐view compared to other light‐sheets.
