Burden E, Seyoum Y, Evans J, Thomas W, Kitson J, Batten T, et al.
J Shoulder Elbow Surg . 2025 Mar; PMID: 40032061
Background: The organisms responsible for periprosthetic joint infections (PJI) of the shoulder are often skin pathogens originating from the patient's own skin flora at the time of surgery. Understanding the...

Elife . 2024 May; 13. PMID: 38780415
Stramenopiles form a clade of diverse eukaryotic organisms, including multicellular algae, the fish and plant pathogenic oomycetes, such as the potato blight , and the human intestinal protozoan . In...

PLoS One . 2023 Dec; 18(12):e0295058. PMID: 38127919
The nitrate (NO3-) reducing bacteria resident in the oral cavity have been implicated as key mediators of nitric oxide (NO) homeostasis and human health. NO3--reducing oral bacteria reduce inorganic dietary...

Zahonova K, Low R, Warren C, Cantoni D, Herman E, Yiangou L, et al.
Curr Biol . 2023 Jun; 33(12):2449-2464.e8. PMID: 37267944
Blastocystis is the most prevalent microbial eukaryote in the human and animal gut, yet its role as commensal or parasite is still under debate. Blastocystis has clearly undergone evolutionary adaptation...

Stensvold C, Ascuna-Durand K, Chihi A, Belkessa S, Kurt O, El-Badry A, et al.
J Eukaryot Microbiol . 2022 Sep; 70(2):e12949. PMID: 36168968
Despite the species' wide distribution, studies of the genetic diversity within Entamoeba coli and Entamoeba hartmanni remain limited. In the present study, we provide further insight into the genetic diversity...

Stensvold C, Sorland B, Berg R, Andersen L, van der Giezen M, Bowtell J, et al.
Microorganisms . 2022 Feb; 10(2). PMID: 35208781
is a unicellular eukaryote found in the gastrointestinal tract of both human and other animal hosts. The clinical significance of colonic colonization remains obscure. In this study, we used metabarcoding...

Herman E, Greninger A, van der Giezen M, Ginger M, Ramirez-Macias I, Miller H, et al.
BMC Biol . 2021 Jul; 19(1):142. PMID: 34294116
Background: The opportunistic pathogen Naegleria fowleri establishes infection in the human brain, killing almost invariably within 2 weeks. The amoeba performs piece-meal ingestion, or trogocytosis, of brain material causing direct...

Genome Biol Evol . 2021 Apr; 13(6). PMID: 33892498
The identification of the asgard archaea has fueled speculations regarding the nature of the archaeal host in eukaryogenesis and its level of complexity prior to endosymbiosis. Here, we analyzed the...

Vanhatalo A, LHeureux J, Kelly J, Blackwell J, Wylie L, Fulford J, et al.
Redox Biol . 2021 Mar; 41:101933. PMID: 33721836
Many oral bacteria reduce inorganic nitrate, a natural part of a vegetable-rich diet, into nitrite that acts as a precursor to nitric oxide, a regulator of vascular tone and neurotransmission....
