Environmental stress promotes the persistence of facultative bacterial symbionts in amoebae

Ecology and Evolution, 2023
Amoebae are one major group of protists that are widely found in natural and engineered environments. They are a significant threat to human health not only because many of them are pathogenic but also due to their unique role as an environmental shelter

First report of Acanthamoebae spp. isolation from a volcanic mud spring in the Philippines

Journal of Water and Health, 2023
Acanthamoebae spp. is considered highly adaptive. The present study aims to establish the occurrence of free-living amoebae, particularly Acanthamoebae, to exist in extreme environments such as volcanic mud springs.

Opportunistic free: Living amoeba now becoming a usual pathogen?

Indian Journal of Pathology and Microbiology, 2017
Acanthamoeba species cause granulomatous Acanthamoeba encephalitis in immunocompromised patients. We report a case of acute purulent meningoencephalitis with a focal neurological deficit caused by Acanthamoeba species in a 2 years immunocompetent child.

Insights From the Genome Sequence of Mycobacterium paragordonae, a Potential Novel Live Vaccine for Preventing Mycobacterial Infections: The Putative Role of Type VII Secretion Systems for an Intracellular Lifestyle Within Free-Living Environmental Predators

Frontiers in Microbiology, 2019
Mycobacterium paragordonae (Mpg) is a temperature-sensitive Mycobacterium species that can grow at permissive temperatures but fails to grow above 37°C. Due to this unique growth trait, Mpg has recently been proposed as a novel live vaccine candidate for

‘Candidatus Cochliophilus cryoturris’ (Coxiellaceae), a symbiont of the testate amoeba Cochliopodium minus

Scientific Reports, 2017
Free-living amoebae are well known for their role in controlling microbial community composition through grazing, but some groups, namely Acanthamoeba species, also frequently serve as hosts for bacterial symbionts.
