Aim: Determine prevalence of genetic determinants of virulence among enterococci strains comprising human intestine microbiota.
Materials And Methods: 81 enterococci strains isolated from intestine of individuals during examination for dysbiosis were used in the study. Strain identification was performed by using multiplex PCR. Hemolytic and gelatinase activity was determined by dish method; genes coding virulence factor synthesis (gelE, sprE, cylM, cylB, cylA, esp)--by PCR.
Results: A wide set of genetic determinants of virulence was detected in E. faecalis strain microorganisms.
Conclusion: Enterococcus genus microorganisms of human intestine microbiota that have virulence potential may become the reason for endogenous infection. The data obtained may be used for prognosis of risk of development of endogenous enterococci infections.

Background And Aims: Inflammatory bowel disease (IBD) develops in genetically susceptible individuals exposed to certain environmental factors, of which only a few have been established. We aimed to assess whether bariatric surgery (BS) and severe obesity are associated with an increased risk of developing IBD.
Methods: Adults diagnosed with obesity or severe obesity between 2005 and 2020 were identified from the Catalan Health Surveillance System; those diagnosed with IBD prior to the diagnosis of obesity or severe obesity were excluded.

Introduction: Colorectal cancer (CRC) is the second most common cause of cancer-related deaths globally. The gut microbiota, along with adenomatous polyps (AP), has emerged as a plausible contributor to CRC progression. This study aimed to scrutinize the impact of the FadA antigen derived from Fusobacterium nucleatum on the expression levels of the ANXA2 ceRNA network and assess its relevance to CRC advancement.

In 2018, Portuguese researchers proposed the "Tool for Quality Assessment of Genetic Counseling," a 5-point Likert scale comprising 50 items across five dimensions, designed to assess genetic counseling from the professional's perspective. This descriptive, cross-sectional study aimed to adapt this tool to Brazilian Portuguese, validate it among Brazilian clinical geneticists, and conduct a preliminary assessment of the quality of genetic counseling in Brazil. The adaptation process involved expert-driven content validation and calculation of the Content Validity Index (CVI) to ensure equivalence between the original and adapted versions.

Mammalian milk contains a variety of complex bioactive and nutritional components and microorganisms. These microorganisms have diverse compositions and functional roles that impact host health and disease pathophysiology, especially mastitis. The advent and use of high throughput omics technologies, including metagenomics, metatranscriptomics, metaproteomics, metametabolomics, as well as culturomics in milk microbiome studies suggest strong relationships between host phenotype and milk microbiome signatures in mastitis.

Background: Interleukin-1 receptor-associated kinase1 (IRAK1) plays a considerable role in the inflammatory signaling pathway. The current study aimed to identify any association between (rs1059703) single nucleotide polymorphism (SNP) and vulnerability to rheumatological diseases in the pediatric and adult Egyptian population.
Patients And Methods: The current study included four patient groups: adult Systemic lupus erythematosus (SLE), Rheumatoid arthritis (RA), juvenile systemic lupus erythematosus (JSLE), and juvenile idiopathic arthritis (JIA).
