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

open access: yesNeuropathology, 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 ...

Free‐Living Amoebas in Extreme Environments: The True Survival in our Planet

open access: yesBioMed 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.

Lethal encounters: The evolving spectrum of amoebic meningoencephalitis

open access: yesIDCases, 2019
The free-living amoebae are thermophilic organisms that may play an increasing role among diseases of a warming world. They are uncommon, accidental, yet high consequence pathogens, with differing pathologic syndromes.

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

open access: yesClinical 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.
