Objective: IBD is an inflammatory disease with abnormalities such as dysbiosis and abnormal immune system activity. Probiotics, as live beneficial microorganisms, play a role in maintaining health through various mechanisms, including the modulation of the immune system and the control of inflammation. Here, we aimed to investigate the efficacy of a probiotic mixture of spp.

Comparison of the prevalence of bacteriocin encoding genes in spp. isolated from fecal samples of healthy volunteers, IBD-patient and IBD-recovered.

Background And Objectives: Bacteriocins are antimicrobial peptides produced by many genera of bacteria especially spp. against many pathogens, adapt bacterial composition in the gut and inhibit dysbiosis that can lead to inflammation disorders like inflammatory bowel disease (IBD). The aim of this study was to compare the prevalence of bacteriocin genes in health, IBD disease and recovery conditions.

The impact of Lactobacillus and Bifidobacterium probiotic cocktail on modulation of gene expression of gap junctions dysregulated by intestinal pathogens.

Probiotics are special bacterial strains with strain specific impacts. They can affect health condition in intestine by producing organic acid, competing with pathogens and maintaining cells homeostasis. Regarding to importance of cell junctions in cells transportation and the influence of pathogens in their functions which lead to inflammation, the impact of probiotic strains comprised of Lactobacillus and Bifidobacterium strains on two important members of gap junctions (Cx26 and Cx43) were assayed.

Anti-inflammatory and immunomodulatory effects of Lactobacillus spp. as a preservative and therapeutic agent for IBD control.

Background: Probiotics have a beneficial effect on inflammatory responses and immune regulation, via Janus kinase/signal transduction and activator of transcription (JAK/STAT) and NF-κB signaling pathways. To evaluate the precise effects of Lactobacillus spp. as a protective and therapeutic agent, we aimed to investigate the efficacy of Lactobacillus spp.

Screening for probiotic characters in lactobacilli isolated from chickens revealed the intra-species diversity of .

Considering the importance of the poultry industry and the increasing interest in alternative growth promoters, probiotics are considered as a potential candidate for use in the poultry industry. In this study, species were isolated from 21 rectal swabs of 11 healthy 6-day-old and 10 healthy 21-day-old chickens and their fecal and feed samples. The isolates were characterized and their probiotic characteristics, including resistance to gastric acid and bile salts, biofilm formation and adherence to epithelium or mucus, amylase and protease activity and production of inhibitory compounds, were assessed.

Characterization of methicillin-resistant Staphylococcus aureus strains in sewage treatment plants in Tehran, Iran.
