Abstract:
Under bile salt treatment, strains display significant differences in their tolerance ability, suggesting the existence of diverse resistance mechanisms in Lactobacillus; however, the genes involved in this protective process are not fully understood. In this study, novel target genes associated with bile salt tolerance in Lactobacillus were identified using comparative genomics for PCR detection and the rapid screening of tolerant strains. The bile salt tolerance of 107 lactobacilli isolated from different origins was assessed, and 26 strains with comparatively large differences were selected

Abstract:
Lactobacillus johnsonii and Lactobacillus zeae are among the lactobacilli with probiotic properties, which occur in sour milk products, cheeses, and to a lesser extent in raw milk. Recently, resistant strains have been detected in various species of lactobacilli. The aim of the study was to determine the incidence of resistant Lactobacillus johnsonii and Lactobacillus zeae strains in various types of raw milk. A total of 245 isolates were identified by matrix-assisted laser desorption/ionization mass spectrometry and polymerase chain reaction methods as Lactobacillus sp., of which 23 isolates

ABSTRACT The developing intestinal microbiota of breast-fed infants is considered to play an important role in the priming of the infants' mucosal and systemic immunity. Generally, Bifidobacterium and Lactobacillus predominate the microbiota of breast-fed infants. In intervention trials it has been shown that lactobacilli can exert beneficial effects on, for example, diarrhea and atopy. However, the Lactobacillus species distribution in breast-fed or formula-fed infants has not yet been determined in great detail.

Abstract:
In order to identify probiotic Lactobacillus for potential use as immunoprobiotics for the amelioration or treatment of inflammatory diseases in the gastrointestinal tract such as Helicobacter pylori-induced gastro-duodenal diseases and Clostridium difficile-associated disease (CDAD), we chose to test for the ability of human-derived Lactobacillus to modulate interleukin-8 (IL8) production in gastrointestinal epithelial cells. Eighty-seven gastric biopsy-derived Lactobacillus isolates were tested for their ability to modulate IL-8 production in H.pylori-stimulated AGS cells and 37 feces-derive
