Isolation and Molecular Identification of Potentially Pathogenic Free‐Living Amoeba in Tap Water Faucets in Quezon City, Philippines

Journal of Parasitology Research, Volume 2026, Issue 1, 2026.
Free‐living amoebae (FLA) are ubiquitous in environmental water and soil, and their presence in water systems for human consumption is a public health concern due to their potential pathogenicity and ability to act as a reservoir for pathogenic bacteria.

Biological characteristics and pathogenicity of Acanthamoeba

Frontiers in Microbiology, 2023
Acanthamoeba is an opportunistic protozoa, which exists widely in nature and is mainly distributed in soil and water. Acanthamoeba usually exists in two forms, trophozoites and cysts. The trophozoite stage is one of growth and reproduction while the cyst

The Microbial Trojan Horse and Antimicrobial Resistance: Acanthamoeba as an Environmental Reservoir for Multidrug Resistant Bacteria

Environmental Microbiology, Volume 27, Issue 11, November 2025.
Bacteria associated with Acanthamoeba exhibit greater antibiotic resistance than those from sediment and, on average, show a higher likelihood of multi‐antibiotic tolerance, reflected in significantly elevated multiple‐antibiotic resistance (MAR) index values.

Metabolic Profile Associated With Encystation in Acanthamoeba

Journal of Eukaryotic Microbiology, Volume 72, Issue 5, September/October 2025.
ABSTRACT The genus Acanthamoeba includes widespread protozoa that can cause severe infections in humans. Their ability to form resistant cysts within infected tissues complicates treatment, making it essential to understand the encystation process for developing effective therapeutic strategies.

Rare Infectious Diseases: Detection and Clinical Implications

iLABMED, Volume 3, Issue 2, Page 148-157, June 2025.
Rare infectious diseases are infections that are uncommon, have a low incidence, and are caused by newly emerging pathogens, cross‐species or ectopic infections, or host immunodeficiencies. The detection and diagnosis of rare infections is one of the main reasons for misdiagnosis and missed diagnosis.

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.

Acanthamoeba castellanii–Mediated Reduction of Interleukin‐1β Secretion and Its Association With Macrophage Autophagy

Scientifica, Volume 2025, Issue 1, 2025.
Noncanonical autophagy including unconventional protein secretion has been extensively studied. Our work focused on a leaderless IL‐1β protein secretion from human macrophage in response to Acanthamoeba castellanii components, Acanthamoeba culture supernatant (CS) and cell lysate (CL), as well as its association with macrophage autophagy.
