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.

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

Detection of protozoan hosts for Legionella pneumophila in engineered water systems by using a biofilm batch test [PDF]

, 2010
Legionella pneumophila proliferates in aquatic habitats within free-living protozoa, 17 species of which have been identified as hosts by using in vitro experiments. The present study aimed at identifying protozoan hosts for L.

Metagenomic deep sequencing of aqueous fluid detects intraocular lymphomas. [PDF]

, 2017
IntroductionCurrently, the detection of pathogens or mutations associated with intraocular lymphomas heavily relies on prespecified, directed PCRs. With metagenomic deep sequencing (MDS), an unbiased high-throughput sequencing approach, all pathogens as ...

Molecular analysis unmasking a Balamuthia mandrillaris: Skin lesion and granulomatous amebic encephalitis by Acanthamoeba sp close to genotype T4 with fatal outcome

Clinical Infection in Practice
Background: Acanthamoeba sp, Balamuthia mandrillaris, are a free-living soil amoeba, has emerged as a causative agent of chronic GAE. Methods: The nasal biopsy was sent to our Laboratory of Pathogenic Protozoa and Endosymbionts (LPEP).
