Abstract Background Necrotizing periodontal diseases (NPDs) are uncommon and severe inflammatory conditions characterized by tissue necrosis, painful ulceration, and rapid clinical progression, frequently associated with systemic immunosuppression. Limited data exist regarding their clinical presentation and management in hospital settings.

Pathogenicity of porcine intestinal spirochetes in gnotobiotic pigs [PDF]
Twelve intestinal spirochete strains of porcine origin were characterized on the basis of their phenotypic properties, by multilocus enzyme electrophoresis, and by pathogenicity testing in gnotobiotic pigs.

Disruption of host cell barriers is a fundamental strategy enabling pathogens to establish a paracellular infection. Here, using dual RNA-Seq, we determine the in vivo host-pathogen transcriptomic landscape upon infection by the extracellular pathogen ...

Genetic and phenotypic characterization of intestinal spirochetes colonizing chickens and allocation of known pathogenic isolates to three distinct genetic groups [PDF]
Infection with intestinal spirochetes has recently been recognized as a cause of lost production in the poultry industry. Little is known about these organisms, so a collection of 56 isolates originating from chickens in commercial flocks in Australia ...

Spirochetes are not sufficient to cause tumorigenesis.
(A) Presence of some bacteria on Hydra is necessary for T. parva to colonize the host. T. parva injected into antibiotic-treated polyps free of bacteria were not able to settle, and neither of injected polyps (0/158) developed tumorous phenotype.

ABSTRACT Gastrointestinal (GI) cancers, including esophageal (EC), gastric (GC), and colorectal cancer (CRC), impose a substantial global burden, with early detection remaining crucial for improving patient outcomes. The oral and gut microbiota are increasingly implicated in cancer development and hold promise as sources of non‐invasive biomarkers ...

Cross‐Reactivity of Treponema pallidum Polyclonal Antibody With Mycobacterium Species
ABSTRACT Introduction Mycobacteria are typically identified using the acid‐fast staining technique. Prior reports have observed cross‐reactivity of Treponema pallidum immunohistochemistry (IHC) with Mycobacterium species, particularly Mycobacterium leprae.

Isolation of Serpulina pilosicoli from rectal biopsy specimens showing evidence of intestinal spirochetosis [PDF]
Histologic evidence of intestinal spirochetosis (IS) was found in 22 of 41 (53.7%) rectal biopsy specimens from homosexual men attending a sexually transmitted diseases clinic. Serpulina pilosicoli was cultured from 11 of the IS-positive biopsy specimens
