Luminal Phospholipase D Attacks Bacterial Membranes in Dictyostelium discoideum Phagosomes

Molecular Microbiology, Volume 124, Issue 1, Page 54-65, July 2025.
This study shows that PldX, a luminal Phospholipase D, is necessary for the efficient destruction of ingested Klebsiella pneumoniae bacteria in Dictyostelium discoideum phagosomes. PldX and the AlyL lysozyme together attack the bacterial membrane and permeabilize it. To date, the molecular substrate of PldX remains to be determined. ABSTRACT Phagocytic

Eukaryote‐Wide Distribution of a Family of Longin Domain‐Containing GAP Complexes for Small GTPases

Traffic, Volume 26, Issue 7-9, July/September 2025.
The three longin domain‐containing GAP complexes ‐ CSW, folliculin, and GATOR1 ‐ have a sporadic but pan‐eukaryotic distribution and were likely already present in LECA in some form. Their catalytic longin domains contain highly conserved sequence motifs, some of which are shared with structurally similar proteins of Asgardarchaeota.

Rare Infectious Diseases: Detection and Clinical Implications

iLABMED, Volume 3, Issue 2, Page 148-157, June 2025.
Rare infectious diseases are infections that are uncommon, have a low incidence, and are caused by newly emerging pathogens, cross‐species or ectopic infections, or host immunodeficiencies. The detection and diagnosis of rare infections is one of the main reasons for misdiagnosis and missed diagnosis.

A giant virus infecting the amoeboflagellate Naegleria

Nature Communications
Giant viruses (Nucleocytoviricota) are significant lethality agents of various eukaryotic hosts. Although metagenomics indicates their ubiquitous distribution, available giant virus isolates are restricted to a very small number of protist and algal ...

Lethal encounters: The evolving spectrum of amoebic meningoencephalitis

IDCases, 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.

Naegleria fowleriin Well Water

Emerging Infectious Diseases, 2008
To the Editor: Naegleria fowleri, a protozoon found in hot springs and warm surface water, can cause primary amebic meningoencephalitis in humans. A survey of drinking water supply wells in Arizona determined that wells can be colonized and may be an unrecognized source of this organism that could present a human health risk. N.

Occurrence of Naegleria and Acanthamoeba in aquaria [PDF]

Applied and Environmental Microbiology, 1979
Samples from 24 aquaria were incubated at 28, 37, and 45 degrees C for the isolation of Naegleria and Acanthamoeba. Naegleria was the predominant genus (60.9%), whereas Acanthamoeba represented 15.5% of the isolates. No pathogenic N. fowleri was identified, although a high number of strains were closely related to this species. One isolate (Aq/9/1/45D)
