Consortium of 2029 and 7247 Strains Shows In Vitro Bactericidal Effect on and, in Combination with Prebiotic, Protects Against Intestinal Barrier Dysfunction.

(CJ) is the etiological agent of the world's most common intestinal infectious food-borne disease, ranging from mild symptoms to fatal outcomes. The development of innovative synbiotics that inhibit the adhesion and reproduction of multidrug-resistant (MDR) CJ in animals and humans, thereby preserving intestinal homeostasis, is relevant. We have created a synbiotic based on the consortium of 2029 (LC2029), 7247 (LS7247), and a mannan-rich prebiotic (Actigen).

A Novel Subsp. T1 Strain from Cow's Milk: Homeostatic and Antibacterial Activity against ESBL-Producing .

The global emergence of antibiotic-resistant zooanthroponotic strains, producing extended-spectrum beta-lactamases (ESBL-E) and persisting in the intestines of farm animals, has now led to the development of a pandemic of extra-intestinal infectious diseases in humans. The search for innovative probiotic microorganisms that eliminate ESBL-E from the intestines of humans and animals is relevant. Previously, we received three isolates of bifidobacteria: from milk of a calved cow (BLLT1), feces of a newborn calf (BLLT2) and feces of a three-year-old child who received fresh milk from this calved cow (BLLT3).

Anti- Defence and Intestinal Homeostatic Maintenance In Vitro of a Consortium Containing 3872 and s 7247 Strains in Human, Porcine, and Chicken Enterocytes.

strain 3872 (LF3872) was originally isolated from the breast milk of a healthy woman during lactation and the breastfeeding of a child. strain 7247 (LS7247) was isolated at the same time from the intestines and reproductive system of a healthy woman. The genomes of these strains contain genes responsible for the production of peptidoglycan-degrading enzymes and factors that increase the permeability of the outer membrane of Gram-negative pathogens.

Protective Properties of S-layer Protein 2 from 2029 against Infections.

Previously, the protective role of the S-layer protein 2 (Slp2) of the vaginal 2029 (LC2029) strain against foodborne pathogens , serovar Enteritidis, and O157:H was demonstrated. We demonstrate the new roles of the Slp2-positive LC2029 strain and soluble Slp2 against infections. We show that LC2029 bacteria can adhere to the surface of the cervical epithelial HeLa cells, prevent their contact with , and block yeast transition to a pathogenic hyphal form.

Mechanosynthesis of Polyureas and Studies of Their Responses to Anions.

Polyureas (PUs) have already found wide practical applications, and various methods of their synthesis have been reported. In this manuscript, we wished to report the very first mechanochemical approach towards aromatic PUs via reactions between isomeric 2,2'-, 3,3'-, and 4,4'-diaminobiphenyls and triphosgene under solvent-free conditions following ball-milling. By using this synthetic approach, both PUs and azomethine-capped Pus were obtained.
