Free‐Living Amoebas in Extreme Environments: The True Survival in our Planet
BioMed Research International, Volume 2022, Issue 1, 2022., 2022 Free‐living amoebas (FLAs) are microorganisms, unicellular protozoa widely distributed in nature and present in different environments, such as water or soil; they are maintained in ecosystems and play a fundamental role in the biological control of bacteria, other protozoa, and mushrooms.

Drugs used for the treatment of cerebral and disseminated infections caused by free‐living amoebae
Clinical and Translational Science, Volume 14, Issue 3, Page 791-805, May 2021., 2021 Abstract Free‐living amoebae (FLAs) are protozoa developing autonomously in diverse natural or artificial environments. The FLAs Acanthamoeba spp., Balamuthia mandrillaris, and Naegleria fowleri represent a risk for human health as they can become pathogenic and cause severe cerebral infections, named granulomatous amoebic encephalitis (GAE ...

Balamuthia mandrillaris resistance to hostile conditions [PDF]
Journal of Medical Microbiology, 2008 The resistance of Balamuthia mandrillaris to physical, chemical and radiological conditions was tested. Following treatments, viability was determined by culturing amoebae on human brain microvascular endothelial cells for up to 12 days. B. mandrillaris cysts were resistant to repeated freeze–thawing (five times), temperatures of up to 70 °C, 0.5 % SDS,

Increasing Importance of Balamuthia mandrillaris [PDF]
Clinical Microbiology Reviews, 2008 SUMMARY Balamuthia mandrillaris is an emerging protozoan parasite, an agent of granulomatous amoebic encephalitis involving the central nervous system, with a case fatality rate of >98%. This review presents our current understanding of Balamuthia infections, their ...

Balamuthia mandrillarisexhibits metalloprotease activities [PDF]
FEMS Immunology & Medical Microbiology, 2006 Balamuthia mandrillaris is a recently identified protozoan pathogen that can cause fatal granulomatous encephalitis. However, the pathogenesis and pathophysiology of B. mandrillaris encephalitis remain unclear. Because proteases may play a role in the central nervous system (CNS) pathology, we used spectrophotometric, cytopathic and zymographic assays ...
