Functional annotation and comparative genomics analysis of Balamuthia mandrillaris reveals potential virulence-related genes [PDF]

Scientific Reports, 2023
Balamuthia mandrillaris is a pathogenic protozoan that causes a rare but almost always fatal infection of the central nervous system and, in some cases, cutaneous lesions. Currently, the genomic data for this free-living amoeba include the description of

Diagnostic challenges in Balamuthia mandrillaris infections

Parasitology Research, 2013
Balamuthia mandrillaris is an emerging cause of subacute granulomatous amebic encephalitis (GAE). The diagnosis of this infection has proven to be difficult and is usually made postmortem. Early recognition and treatment may offer some benefit. This report describes a previously healthy woman who died from GAE due to B. mandrillaris.

Fatal amoebic meningoencephalitis caused by Balamuthia mandrillaris in Pongo pygmaeus and first case report in Pan troglodytes verus [PDF]

Frontiers in Veterinary Science
Balamuthia mandrillaris is an amoeba that can cause granulomatous amoebic encephalitis (GAE) as well as lung and skin infections in both humans and animals. Studies on B. mandrillaris-related GAE cases have increased in recent years. This amoeba has been

The role of plasma metagenomic sequencing in identification of Balamuthia mandrillaris encephalitis [PDF]

Acta Neuropathologica Communications
Balamuthia mandrillaris is a rare, free-living amoeba (FLA) that causes granulomatous amoebic encephalitis, a disease with close to 90% mortality. The geographical ranges of many FLA are expanding, potentially increasing human exposure to B. mandrillaris.

Balamuthia mandrillaris trophozoites ingest human neuronal cells via a trogocytosis-independent mechanism [PDF]

Parasites & Vectors, 2022
Background Environmental protozoa need an adaptation mechanism to survive drastic changes in niches in the human body. In the brain parenchyma, Balamuthia mandrillaris trophozoites, which are causative agents of fatal brain damage, must acquire nutrients

Balamuthia mandrillaris: Morphology, biology, and virulence

Tropical Parasitology, 2015
Balamuthia mandrillaris is a protist pathogen that can cause encephalitis with a fatality rate of >95%. This is due to our incomplete understanding of the pathogenesis and pathophysiology of B. mandrillaris encephalitis. B. mandrillaris has two stages in its life cycle, an active trophozoite stage during which it divides mitotically.

Diagnosing Balamuthia mandrillaris encephalitis via next-generation sequencing in a 13-year-old girl

Emerging Microbes and Infections, 2020
Balamuthia amoebic encephalitis has a subacute-to-chronic course and is almost invariably fatal owing to delayed diagnosis and a lack of effective therapy.
