Acanthamoeba Infection in a Hematopoietic Cell Transplant Recipient: Challenges in Diagnosis, Management, and Source Identification

Transplant Infectious Disease, Volume 27, Issue 1, January/February 2025.
Acanthamoeba infection in HCT recipients, represent multiple challenges. Early diagnosis, and effective treatment, remain the main barriers to survival. High index of suspicion, may help in identifying cases earlier. Given its ubiquiteness, source identification remains challenging.

A type-1 metacaspase from Acanthamoeba castellanii

Microbiological Research, 2008
The complete sequence of a type-1 metacaspase from Acanthamoeba castellanii is reported comprising 478 amino acids. The metacaspase was recovered from an expression library using sera specific for membrane components implicated in stimulating encystation.

Infant‐Type Bifidobacteria as Biocontrol Agents: Suppressing Listeria monocytogenes via Key Virulence Gene Alteration

Canadian Journal of Infectious Diseases and Medical Microbiology, Volume 2025, Issue 1, 2025.
Infant‐type bifidobacteria exhibit potential as targeted biocontrol agents against Listeria monocytogenes infections. However, the strain‐specific antimicrobial efficacy and molecular mechanisms remain insufficiently characterized. In this study, the probiotic potential of five bifidobacteria strains was systematically evaluated through comprehensive ...

SJL Mice Infected with Acanthamoeba castellanii Develop Central Nervous System Autoimmunity through the Generation of Cross-Reactive T Cells for Myelin Antigens [PDF]

, 2014
We recently reported that Acanthamoeba castellanii (ACA), an opportunistic pathogen of the central nervous system (CNS) possesses mimicry epitopes for proteolipid protein (PLP) 139–151 and myelin basic protein 89–101, and that the epitopes induce ...

The Characterisation of an Adrenergic Signalling System Involved in the Encystment of the Ocular Pathogen Acanthamoeba spp. [PDF]

, 2016
The aim of this study was to identify and characterise the receptor system involved in controlling encystment in Acanthamoeba using specific agonists and antagonists and to examine whether endogenous stores of catecholamines are produced by the organism.

Origin and evolution of microvilli

Biology of the Cell, Volume 116, Issue 11, November 2024.
Microvilli are widespread organelles of animal cells that frequently play a role in sensation and feeding. Ansel et al. reconstitute their origin and evolution by performing a broad morphological survey of microvilli in animals and their unicellular relatives, coupled with a bioinformatic study of the phylogenetic distribution of the main microvillar ...

The role of Src kinase in the biology and pathogenesis of Acanthamoeba castellanii

Parasites & Vectors, 2012
Background Acanthamoeba species are the causative agents of fatal granulomatous encephalitis in humans. Haematogenous spread is thought to be a primary step, followed by blood–brain barrier penetration, in the transmission of Acanthmaoeba into the ...
