Gut , , and spp. as Possible Markers in Women-Related Nutritional and Clinical Trials: Familial Mediterranean Fever Disease.

Background: Studies have shown that the gut microbiota of healthy men and men with familial Mediterranean fever (FMF) disease respond differently to placebo. Given the fact that the composition of the gut microbiota is different in men and women, this study aimed to describe in detail the placebo response of the gut microbiota in healthy and FMF women.

Materials And Methods: The bacterial response to placebo was fully evaluated on a previous PhyloChip™ DNA microarray-based assay (GEO Series; accession number GSE111835).

Challenges for heat stress: Intestinal culturable bacteria of Lohmann Brown chickens.

This study aimed to assess how heat stress, specifically within the range of 35-38 °C, affects the populations of culturable intestinal lactobacilli, enterococci, and Escherichia coli, as well as the expression of Heat Shock Proteins (HSP70), in Lohmann Brown chickens. It also explored the influence of the chickens' blood transferrin and ceruloplasmin genotypes on these responses. Thirty chickens underwent eight hours of heat stress, maintained at an average temperature of 37 °C and a relative humidity of 75-80%, with continuous access to food and water.

Placebo-resistant gut bacteria: spp. and Familial Mediterranean fever disease.

Introduction: Despite numerous investigations into the impact of drugs/probiotics on the gut microbiota composition in Familial Mediterranean Fever (FMF) patients, the question as to whether there exists a significant bacterial diversity(ies) independent of the placebo effect that can be reliably considered in clinical and nutritional trials remains unresolved.

Methods: This study represents the in augural analysis of the placebo's influence on the gut microbiota of both healthy individuals and FMF afflicted men, utilizing previously collected data from PhyloChip™ DNA microarray experiments. A total of 15 healthy and 15 FMF male volunteers, aged 18 to 50, participated in this partially randomized placebo trial, which is accessible through the GEO Series accession number GSE111835.

Host genetics and gut microbiota composition: Baseline gut microbiota composition as a possible prognostic factor for the severity of COVID-19 in patients with familial Mediterranean fever disease.

Objective: Current investigations aimed to evaluate the associations between the baseline gut microbiota composition of healthy and Familial Mediterranean fever (FMF) - carrier Armenian men populations, and the severity of the COVID-19 disease after their infection with the SARS-CoV-2.

Evaluation of Malondialdehyde Levels, Oxidative Stress and Host-Bacteria Interactions: and Derby.

Either extracts, cell-free suspensions or bacterial suspensions are used to study bacterial lipid peroxidation processes. Along with gas chromatography-mass spectrometry, liquid chromatography-mass spectrometry, and several other strategies, the thiobarbituric acid test is used for the determination of malondialdehyde (MDA) as the basis for the commercial test kits and the colorimetric detection of lipid peroxidation. The aim of the current study was to evaluate lipid peroxidation processes levels in the suspensions, extracts and culture supernatants of and Derby strains.

One Health Probiotics as Biocontrol Agents: One Health Tomato Probiotics.

Tomato () is one of the most popular and valuable vegetables in the world. The most common products of its industrial processing in the food industry are juice, tomato paste, various sauces, canned or sun-dried fruits and powdered products. Tomato fruits are susceptible to bacterial diseases, and bacterial contamination can be a risk factor for the safety of processed tomato products.

The Effect of Immunobiotic/Psychobiotic Lactobacillus acidophilus Strain INMIA 9602 Er 317/402 Narine on Gut Prevotella in Familial Mediterranean Fever: Gender-Associated Effects.

Possible mechanisms involved in sex-dependent differences in the gut microbiota have a growing interest worldwide, but the effects of probiotics dependence on the gender of the host have remained outside of researchers' attention until now. Previously, our research data described gender-specific differences in the gut microbiota of Armenian Familial Mediterranean fever (FMF) patients. Taking into account the possible association of Prevotella spp.

The Effectiveness of Potential Probiotics Lactobacillus rhamnosus Vahe and Lactobacillus delbrueckii IAHAHI in Irradiated Rats Depends on the Nutritional Stage of the Host.

Several species of eukaryotic organisms living in the high mountain areas of Armenia with naturally occurring levels of radiation have high adaptive responses to radiation. We speculate on the role of the gastrointestinal microbiota in this protection against radiation. Therefore, seventeen microorganisms with high antagonistic activities against several multi-drug-resistant pathogens were isolated from the human and animal gut microbiota, as well as from traditional Armenian fermented products.

Blood protein polymorphisms and the gut bacteria: impact of probiotic Narine on carriage in sheep.

Related to previous reports on correlations between an animal's genotype, its commensal microbiota, and the ability to resist infections, the aim of the current study was to investigate the associations between sheep genotype and 5-methylcytosine (5-mC) DNA methylation patterns, sheep genotype and cell surface hydrophobicity of sheep gut commensal bacteria. In addition, the effect of the probiotic strain INMIA 9602 Er 317/402 (probiotic formulation Narine) on carriage in sheep at Armenian farms was also investigated. Allelotypes and genotypes of different pathogen-sensitive sheep breeds from Armenian farms were studied based on genetic markers of blood transferrin, albumin, and ceruloplasmin.

Plant-associated and soil microbiota composition as a novel criterion for the environmental risk assessment of genetically modified plants.

The impact of genetically modified plants on plant-associated and surrounding soil microorganisms is an uninvestigated area of environmental risk assessment. Biological markers such as lysine racemase, phosphomannose isomerase, and sulfadiazine are in use or suggested for use in plant genetic transformation technologies to confirm that the uptake of DNA has occurred. Similar to the effects of antibiotic-resistance genes, these markers might change the host plant's microbiota.

Probiotic Strain INMIA 9602 Er 317/402 Administration Reduces the Numbers of and Abundance of Enterobacteria in the Gut Microbiota of Familial Mediterranean Fever Patients.

Intestinal microorganisms play a crucial role in health and disease. The disruption of host-microbiota homeostasis has been reported to occur not only during disease development but also as a result of medication. Familial Mediterranean fever (FMF) is an inflammatory genetic disease characterized by elevated systemic reactivity against the commensal gut microbiota and high levels of in the gut.

The study of antibiotic resistance of Escherichia coli from the intestinal microbiota in patients with familial mediterranean fever reveald a large number of resistant and multiresistant isolates.

Modification of the biophysical characteristics of membranes in commensal Escherichia coli strains from breast cancer patients.

Escherichia coli G35 N49 strain, from the gut of breast cancer patients, in comparison with the E. coli G35 N61 strain, from the gut of healthy people, shows in vitro reduction in growth rates and maximal growth yield. The changes in certain membrane characteristics, such as low membrane potential and disturbance in intramembrane interaction of H+ -ATPase F0F1 with the TrkA system, indicate a dysfunction in ion transport and enzymatic activity.
