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.

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,

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 ...

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 ...

A Japanese case of amoebic meningoencephalitis initially diagnosed by cerebrospinal fluid cytology

Clinical Case Reports, Volume 8, Issue 9, Page 1728-1734, September 2020., 2020
Microscopy can detect the presence of amoebic trophozoites in cerebrospinal fluid and tissue. The infection was confirmed in the present case by polymerase chain reaction and immunohistochemistry, but we were unable to achieve a cure. Our case rapidly progressed without any skin lesions.

A clinical case report of Balamuthia granulomatous amoebic encephalitis in a non-immunocompromised patient and literature review

BMC Infectious Diseases, 2023
Background Balamuthia granulomatous amoebic encephalitis (GAE) is a peculiar parasitic infectious disease of the central nervous system, about 39% of the infected Balamuthia GAE patients were found to be immunocompromised and is extremely rare clinically.

Microglia in neuropathology caused by protozoan parasites

Biological Reviews, Volume 95, Issue 2, Page 333-349, April 2020., 2020
ABSTRACT Involvement of the central nervous system (CNS) is the most severe consequence of some parasitic infections. Protozoal infections comprise a group of diseases that together affect billions of people worldwide and, according to the World Health Organization, are responsible for more than 500000 deaths annually. They include African and American

An Optical and Chemiluminescence Assay for Assessing the Cytotoxicity of Balamuthia mandrillaris against Human Neurospheroids

Bioengineering, 2022
A spheroid is a cell aggregate in a three-dimensional context; thereby, it recapitulates the cellular architecture in human tissue. However, the utility of spheroids as an assay for host–parasite interactions remains unexplored.
