Entamoeba histolytica‐associated proctitis and ileitis mimicking Crohn's disease—A case report

Clinical Case Reports, Volume 11, Issue 5, May 2023., 2023
Abstract We report about a proctitis and ileitis terminalis, leading to the misdiagnosis of Chron's disease, in a male patient who has sex with men. Molecular multiplex analysis identified Entamoeba histolytica as the underlying cause. We provide diagnostic images, clues and pitfalls for diagnosis of E. histolytica associated proctitis.

Serum positivity of serum anti‐tissue transglutaminase immunoglobulin A antibodies in Japanese children with inflammatory bowel disease

Pediatrics International, Volume 65, Issue 1, January/December 2023., 2023
Abstract Background Serum anti‐tissue transglutaminase immunoglobulin A antibody (tTG‐IgA) is a screening test for celiac disease (CeD). In recent years, there have several reports of combined inflammatory bowel disease (IBD) and CeD in children. The purposes of this study are to research the positivity of the tTG‐IgA antibody in Japanese children, and

Elevated F‐EDN correlates with mucosal eosinophil degranulation in patients with IBS—A possible association with microbiota?

Journal of Leukocyte Biology, Volume 111, Issue 3, Page 655-665, March 2022., 2022
Graphical Abstract Fecal eosinophil‐derived neurotoxin (F‐EDN) levels are correlated to degranulation of eosinophils in the colon of irritable bowel syndrome (IBS) patients. Abstract Eosinophils have been linked to functional dyspepsia; however, less is known about their role in irritable bowel syndrome (IBS).

Maximum levels of cross‐contamination for 24 antimicrobial active substances in non‐target feed. Part 8: Pleuromutilins: tiamulin and valnemulin

EFSA Journal, Volume 19, Issue 10, October 2021., 2021
Abstract The specific concentrations of tiamulin and valnemulin in non‐target feed for food‐producing animals, below which there would not be an effect on the emergence of, and/or selection for, resistance in bacteria relevant for human and animal health, as well as the specific antimicrobial concentrations in feed which have an effect in terms of ...

Diagnostic accuracy of point of care faecal immunochemical testing using a portable high‐speed quantitative analyser for diagnosis in 2‐week wait patients

Colorectal Disease, Volume 23, Issue 9, Page 2376-2386, September 2021., 2021
Abstract Aim Laboratory‐based faecal immunochemical testing (FIT) is the gold standard for detecting the presence of blood in the stool. The aim was to perform a diagnostic accuracy study to confirm if a point of care (POC) analyser for FIT could be safely used as an adjunct in the triage and management of 2‐week wait (TWW) colorectal patients ...

Optimized bacterial DNA isolation method for microbiome analysis of human tissues

MicrobiologyOpen, Volume 10, Issue 3, June 2021., 2021
We present a bacterial DNA isolation method for human colon biopsies which includes reduction of human DNA and does not distort relative bacterial abundance at the phylum level. Shotgun sequencing resulted in 508/521 metagenomes (Shannon index; 2.9, UniFrac distance; 0.56).

Extensive hepatic portal venous gas and gastric pneumatosis in a cat

Veterinary Medicine and Science, Volume 7, Issue 2, Page 593-599, March 2021., 2021
This report describes a case of hepatic portal venous gas (HPVG) in a feline visualized initially on ultrasound and ultimately confirmed with CT, which is considered the gold‐standard for identification in humans. HPVG is associated with a variety of underlying disease processes, some of which require emergent aggressive intervention and may result in ...

In Vitro Cultivation of the Syphilis Spirochete Treponema pallidum

Current Protocols, Volume 1, Issue 2, February 2021., 2021
Abstract For over a century, investigation of Treponema pallidum subsp. pallidum, the spiral‐shaped bacterium that causes syphilis, was hindered by an inability to culture the organism in vitro. A recent breakthrough has enabled continuous in vitro growth of this organism in co‐culture with mammalian tissue culture cells.

Novel multiplex TaqMan assay for differentiation of the four major pathogenic Brachyspira species in swine

MicrobiologyOpen, Volume 10, Issue 1, February 2021., 2021
A novel TaqMan 5‐plex real‐time PCR was developed for the identification of Brachyspira species in swine. B. hyodysenteriae, B. pilosicoli, and B. suanatina are identified using three hydrolysis probes targeting cpn60, while B. hampsonii is recognized by another nox specific probe.
