Abstract Alterations in gut microbiota have been reported in coeliac disease (CeD). However, longitudinal evidence distinguishing disease-related effects from diet-driven changes after gluten-free diet initiation remains scarce, particularly in pediatric cohorts. The present study aimed to evaluate time-dependent changes in selected intestinal …

BACKGROUND The presence of human leukocyte antigen (HLA)-DQ2 and/or HLA-DQ8 alleles is necessary but not sufficient for the development of celiac disease (CeD). This suggests that additional environmental and biological factors, including bacteria and, above all, the still rarely studied fungal gut …

Tuberculosis is still one of the leading infectious causes of morbidity and mortality worldwide. Rapid diagnosis is essential for effective treatment and control of tuberculosis transmission. In recent years, nucleic acid amplification tests (NAATs), such as GeneXpert MTB/RIF, BD MAX™, Xpert MTB/RIF-Ultra, …

BACKGROUND: The gut microbiome has been increasingly recognized for its potential role in schizophrenia through gut-brain interactions involving immune, neural, and metabolic pathways. This pilot study evaluated the impact of fecal microbiota transplantation (FMT) on the abundance and variability of selected fungal …

Background: Helicobacter pylori is a Gram-negative bacterium responsible for various gastrointestinal diseases, including peptic ulcers and gastric cancer. Despite available antibiotic therapies, increasing resistance to clarithromycin—a key antibiotic in eradication regimens—poses a significant challenge. This resistance is primarily linked to point mutations …

The real-time reverse-transcriptase polymerase-chain-reaction (rRT-PCR) tests are the gold standard in detecting SARS-CoV-2 virus infection. However, despite high sensitivity and specificity, they have limitations that in some cases may result in false negative results. Therefore, it is reasonable to search for additional …
