An autopsy case of granulomatous amebic encephalitis caused by Balamuthia mandrillaris involving prior amebic dermatitis

Neuropathology, Volume 42, Issue 3, Page 190-196, June 2022., 2022
An 82‐year‐old man, who was healthy and had worked as a farmer, experienced worsening neurological symptoms over a seven‐month period, which eventually caused his death. Multiple fluctuating brain lesions were detected radiographically. Clinically, sarcoidosis was ranked high among the differential diagnoses because of the presence of skin lesions ...

A Case of Balamuthia mandrillaris Meningoencephalitis [PDF]

Archives of Neurology, 2000
Balamuthia mandrillaris is a newly described pathogen that causes granulomatous amebic encephalitis, an extremely rare clinical entity that usually occurs in immunosuppressed individuals. We report a case of pathologically proven Balamuthia encephalitis with unusual laboratory and radiologic findings.

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

Tropical Parasitology, 2021
Balamuthia mandrillaris is an opportunistic, free-living ameba that is pathogenic to humans. It has a worldwide distribution but is mainly detected in warmer regions. Balamuthia infections are rare but have been reported in both immunocompetent and immunocompromised individuals of all ages. B.

Subacute encephalitis in an immunocompetent patient diagnosed by next-generation sequencing

Journal of International Medical Research, 2022
Balamuthia mandrillaris is a free-living heterotrophic amoeba found in soil that causes a rare and usually fatal granulomatous amebic encephalitis. We report an immunocompetent patient infected with B.

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.

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.

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
