Xenotransplantation, Volume 30, Issue 5, September/October 2023., 2023 Abstract Xenotransplantation has the potential to address shortages of organs available for clinical transplantation, but concerns exist regarding potential risks posed by porcine microorganisms and parasites (MP) to the health of human recipients. In this study, a risk‐based framework was developed, and expert opinion was elicited to evaluate porcine ...

Positive associations matter: Microbial relationships drive tick microbiome composition
Molecular Ecology, Volume 32, Issue 14, Page 4078-4092, July 2023., 2023 Abstract Untangling how factors such as environment, host, associations among bacterial species and dispersal predict microbial composition is a fundamental challenge. In this study, we use complementary machine‐learning approaches to quantify the relative role of these factors in shaping microbiome variation of the blacklegged tick Ixodes scapularis ...

Transcriptional and functional characterizations of multiple flagellin genes in spirochetes
Molecular Microbiology, Volume 118, Issue 3, Page 175-190, September 2022., 2022 The oral spirochete Treponema denticola has periplasmic flagella (PFs) that are mainly composed of three flagellin proteins (FlaB1, FlaB2 and FlaB3) and a sheath protein FlaA. Each protein contributes to the motility but none of them is absolutely required.

Spherical body formation in the spirochaeteBrachyspira hyodysenteriae [PDF]
FEMS Microbiology Letters, 2006 When cultures of Brachyspira hyodysenteriae were grown under a wide range of in vitro conditions, at least 1% of the cells formed spherical bodies different to the normal helical form. This percentage increased considerably in aging cultures or following their incubation in caramelized media.
