Dairy effluent management systems as a potential persistence source of Shiga toxin-producing Escherichia coli (STEC) strains.

Shiga toxin-producing Escherichia coli (STEC) is a group of pathogenic enterobacteria of significant public health importance due to their association with highly prevalent human diseases. STEC is ubiquitous in livestock environments, and its presence in the environment emphasizes the importance of properly managing agricultural effluents to reduce health risks from contamination. In order to detect STEC in the effluent treatment systems of two dairy farms ("A" and "B") in the southwest of Buenos Aires province, samples ("A", n=88; "B", n=72) were taken at two different times of the year (winter and spring) and at various points in the treatment systems.

Winter cover crop suppression methods influence on sunflower growth and rhizosphere communities.

Sunflower ( L.), a vital crop for global vegetable oil production, encounters sustainability challenges in its cultivation. This study assesses the effects of incorporating a winter cover crop (CC), (L.

New insights into the regulation of bile acids synthesis during the early stages of liver regeneration: A human and experimental study.

Background And Aims: Liver regeneration is essential for the preservation of homeostasis and survival. Bile acids (BAs)-mediated signaling is necessary for liver regeneration, but BAs levels need to be carefully controlled to avoid hepatotoxicity. We studied the early response of the BAs-fibroblast growth factor 19 (FGF19) axis in healthy individuals undergoing hepatectomy for living donor liver transplant.

[Molecular characterization of diarrheagenic Escherichia coli from an outpatient pediatric population with diarrhea attended in two hospitals from Buenos Aires, Argentina].

Diarrheagenic Escherichia coli comprises a heterogeneous group of pathotypes or pathogenic variants that share phenotypic characteristics with marked differences in virulence genes, colonization sites, pathogenesis, clinical presentation, and epidemiology of infection. The most studied pathotypes are Shiga toxin-producing E.coli (STEC), enterotoxigenic E.

[IGG4-related disease. Report of 52 patients].

Background: IgG4-related disease (IgG4 RD) is an immune-mediated fibro-inflammatory disorder, with tissue infiltration of IgG4+ plasma cells. It causes pseudotumors, tumors, and a wide spectrum of clinical manifestations.

Aim: To report the clinical, laboratory, histopathological and treatment characteristics of a group of Chilean patients with IgG4 RD.
