Changes in Microbiota and Short-Chain Fatty Acids, Lipopolysaccharide-Binding Protein and Zonulin in People with Breast Cancer Fatma Hümeyra Yerlikaya, Mustafa Topkafa, Hande Köksal, Salih Maçin, Serdar Yormaz, Abdullah Sivrikaya, Sedat Abuşoğlu, Duygu Eryavuz Onmaz, Uğur Arslan, Nurullah Çiftçi Bratislava Medical Journal, 2026 Gut microbiota and its metabolites are increasingly recognized for their roles in cancer pathogenesis. This study aimed to identify differences in gut microbial composition and metabolic markers between breast cancer patients and healthy individuals. We compared newly diagnosed breast cancer patients with healthy controls. Fecal short-chain fatty acids (SCFAs) were measured using gas chromatography, while serum zonulin and lipopolysaccharide-binding protein (LBP) were quantified via ELISA. Gut microbiome composition was analyzed through 16S rRNA sequencing of 30 representative fecal samples. Analysis of 65 patients and 50 controls revealed significant microbial discrepancies at the family, genus, and species levels. Serum LBP levels were significantly higher in the breast cancer group in univariate analysis ( p = 0.007). In multivariable models adjusted for glucose and cholesterol, butyrate (molar %) remained a robust independent predictor of breast cancer (OR: 1.127, p = 0.042). However, LBP lost its significance in the multivariable model ( p = 0.169), suggesting its elevation is closely associated with the host’s metabolic profile rather than acting as a standalone driver. No significant differences were found in zonulin levels. Our findings demonstrate distinct microbial signatures and metabolic shifts in breast cancer. The independence of butyrate as a predictor, contrasted with the metabolism-dependent rise of LBP, highlights a complex gut-metabolic axis in breast cancer pathogenesis. Further large-scale research is needed to refine these markers for clinical use.

Oral Microbiota Alterations and Potential Salivary Biomarkers in Colorectal Cancer: A Next-Generation Sequencing Study Salih Maçin, Özben Özden, Rugıyya Samadzade, Esra Saylam, Nurullah Çiftçi, Uğur Arslan, Serdar Yormaz Pathogens, 2026 Colorectal cancer (CRC) has a high mortality rate worldwide. Oral and intestinal microbiota members may have an effect on gastrointestinal tumors’ pathogenesis, particularly in CRC. Designed as a pilot study, this study’s aim was to investigate the relationship between CRC and oral microbiota and to identify potential biomarkers for CRC diagnosis. Saliva samples were collected from recently diagnosed CRC patients (n = 14) and healthy controls (n = 14) between March 2023 and December 2023. Microbiota (16S rRNA) analyses were conducted on these saliva samples using a next-generation sequencing method. Phylogenetic analyses, including alpha diversity, principal component analysis (PCA), principal coordinate analysis (PCoA), beta diversity, biomarker, and phenotype analyses, were conducted using the Qiime2 (Quantitative Insights Into Microbial Ecology) platform. Alpha diversity indices (Shannon: p = 0.78, Cho1: p = 0.28, Simpson: p = 0.81) showed no significant difference between CRC and control groups. Beta diversity analysis using Bray–Curtis PCoA indicated significant differences in the microbial community between the two groups (p = 0.003). Examination of OTU distributions revealed that the Mycoplasmatota phylum was undetectable in the oral microbiota of healthy controls but was significantly elevated in CRC patients (CRC: 0.13 ± 0.30, Control: 0.00 ± 0.00, p < 0.05). Additionally, Metamycoplasma salivarium, Bacteroides intestinalis, and Pseudoprevotella muciniphila were undetectable in healthy controls but significantly more prevalent in CRC patients (p < 0.05 for all three species). LEfSe analysis identified eight species with an LDA score > 2, Granulicatella adiacens, Streptococcus thermophilus, Streptococcus gwangjuense, Capnocytophaga sp. FDAARGOS_737, Capnocytophaga gingivalis, Granulicatella elegans, Bacteroides intestinalis, and Pseudoprevotella muciniphila, as potential biomarkers. The results of this study contribute critical evidence of the role of oral microbiota in the pathogenesis of colorectal cancer. Alterations in the microbiota suggest potential biomarkers in understanding the biological mechanisms underlying CRC and developing diagnostic and therapeutic strategies.
Comparison of the Intestinal Microbiota of Patients with Urticaria and Healthy Controls: The Role of Blastocystis Nurullah Ciftci, Salih Macin, Gülcan Saylam Kurtipek, Uğur Arslan Pathogens, 2025 Urticaria is a skin disorder characterized by erythematous, edematous, and pruritic lesions. Intestinal microorganisms can trigger various immunological responses, and Blastocystis has been suggested to affect gut-associated lymphoid tissue homeostasis and induce allergic reactions. This study aimed to evaluate the effect of Blastocystis on the intestinal microbiota in patients with urticaria. A total of 33 patients diagnosed with urticaria and 34 healthy controls were included. Independent sample t-tests, Welch’s t-tests, or Mann–Whitney U tests were applied to assess differences in the Shannon, Simpson, and Chao-1 indices between groups. Significant differences were observed in Proteobacteria (p = 0.015), Bacteroidetes (p = 0.008), Escherichia (p = 0.005), Phocaelcola (p = 0.043), and Prevotella (p = 0.047) between the urticaria and control groups. Bacteroidetes (p = 0.003) and Phocaelcola (p = 0.032) also differed significantly between samples with and without Blastocystis. Overall microbiota composition showed a significant difference between Blastocystis-positive and -negative samples (p = 0.009). The Firmicutes/Bacteroidetes ratio was 4.1 in healthy controls and 6.4 in urticaria patients. In conclusion, both urticaria and Blastocystis infection significantly influence intestinal microbiota composition, suggesting a potential interaction between Blastocystis colonization and host immune regulation in urticaria.
Investigation of Virulence Genes in Campylobacter Species Isolated from Patients with Acute Diarrhea Masma Shahbazova, Nurullah ÇİFTÇİ, Hatice TÜRK DAĞI, Uğur ARSLAN Mikrobiyoloji Bulteni, 2025 Akut gastroenterit dünya genelinde en yaygın enfeksiyon hastalıklarından biridir. Bu hastalıklar gelişmekte olan ülkelerde çocuk ölümlerine ve ciddi ekonomik kayıplara neden olmuştur. Hastalık genellikle yaygın diyare şeklinde kendini gösterse de bazı olgularda şiddetli enfeksiyon belirtilerine, hatta ölümlere neden olmuştur. Bu çalışmada, gastroenterit şikayetiyle hastaneye başvurmuş hastalardan alınan gaita örneklerinden izole edilen Campylobacter türlerinin tanımlanması, virülans genlerinin polimeraz zincir reaksiyonu [polymerase chain reaction (PCR)] ile araştırılması amaçlanmıştır. Campylobacter sıklığının tespiti için gastroenterit şüphesi olan 850 hasta örneği çalışmaya dahil edilmiştir. Campylobacter izolasyonu için dışkı örnekleri modifiye charcoal sefoperazon deoksikolat agar besiyerine ekilip 42 °C'de 48-72 saat mikroaerofilik şartlarda inkübasyona bırakılmıştır. Campylobacter şüpheli kolonilere katalaz, oksidaz ve Gram boyama yapılmıştır. Dışkıların makroskobik incelemesinde dışkının kıvamı, mukus durumu ve lökosit varlığı araştırılmıştır. DNA izolasyonu taze üreyen kolonilerden ticari QIAampDNA mini kit (Qiagen, Almanya) protokolüne göre yapılmıştır. Bakterilerin tanımlanması ve virülans genlerinin varlığı PCR ile araştırılmıştır. Campylobacter cinsi izolatların moleküler olarak tanımlanmasında 16S rRNA genine spesifik 816 baz çifti (bp) uzunluğundaki C412F ve C1228R primer çifti kullanılmıştır. Campylobacter jejuni'nin hippurase genine spesifik olan 735 bp uzunluğundaki HipO1 ve HipO2 primer çifti kullanılmıştır. Campylobacter coli'nin ise asperkinase genine özel 500 bp uzunluğundaki CC1 ve CC2 primerleri kullanılmıştır. Çalışmada incelenen 850 örneğin 122'sinde Campylobacter spp. üremesi tespit edilmiştir. Pozitif örneklerin 107 (%87.7)'si poliklinik hastalarından, 15 (%12.3)'i ise serviste yatan hastalardan izole edilmiştir. Hastaların yaş grubuna göre dağılımı incelendiğinde en yüksek oranda pozitiflik %39.4 (48) ile 0-5 yaş arasındaki çocuklarda saptanmıştır. PCR ile bu izolatların 106'sı C.jejuni, 11'i C.coli ve beşi Campylobacter spp. olarak tanımlanmıştır. Campylobacter izolatlarının 102 (%83.6)'sinde ciaB geni, 93 (%76.2)'ünde dnaJ geni, 106 (%86.8)'sında cdtC geni ve 115 (94.2%)'inde cdtA geni tespit edilmiştir. cdtB, pldA ve cadF genleri sırasıyla 110 (%90.1), 85 (%69.6) ve 110 (%90.1) izolatta pozitif olarak tespit edilmiştir. Virülans genlerinin türlere göre dağılımına bakıldığında; cadF geninin C.coli izolatlarının hepsinde bulunduğu, cdtA ve ciaB genlerinin diğer Campylobacter spp. izolatlarının tamamında saptandığı tespit edilmiştir. C.jejuni izolatlarının 68'inde, C.coli izolatlarının üçünde, Campylobacter spp. izolatlarının birinde tüm genler pozitif saptanmıştır. Çalışmadaki veriler Campylobacter'in akut gastroenterit hastalıklarında yüksek oranda saptandığını göstermiştir. Bu çalışmanın, klinisyenlerin Campylobacter enfeksiyonlarına olan yaklaşımında yardımcı olacağı düşünülmektedir.
Investigation of Intestinal Microbiota and Short-Chain Fatty Acids in Colorectal Cancer and Detection of Biomarkers Esra Saylam, Özben Özden, Fatma Hümeyra Yerlikaya, Abdullah Sivrikaya, Serdar Yormaz, Uğur Arslan, Mustafa Topkafa, Salih Maçin Pathogens, 2025 Colorectal cancer (CRC) is one of the most common cancers worldwide and a significant global health issue. The human gut microbiota, a complex ecosystem hosting numerous microorganisms such as bacteria, viruses, fungi, and protozoa, plays a crucial role. Increasing evidence indicates that gut microbiota is involved in CRC pathogenesis. In this study, the gut microbiota profiles, short-chain fatty acids, zonulin, and lipopolysaccharide-binding protein levels of newly diagnosed CRC patients were analyzed along with healthy controls to elucidate the relationship between CRC and the gut microbiota. The study included 16 newly diagnosed CRC patients and 16 healthy individuals. For microbiota analysis, DNA isolation from stool samples was performed using the Quick-DNA™ Fecal/Soil Microbe Miniprep Kit followed by sequencing using the MinION device. Data processing was conducted using Guppy software (version 6.5.7) and the Python (3.12) programming language. ELISA kits from Elabscience were utilized for analyzing LBP and zonulin serum levels. Fecal short-chain fatty acids were analyzed using GC-MS/MS equipped with a flame ionization detector and DB-FFAP column. Microbial alpha diversity, assessed using Shannon and Simpson indices, was found to be lower in CRC patients compared to healthy controls (p = 0.045, 0.017). Significant differences in microbial beta diversity were observed between the two groups (p = 0.004). At the phylum level, Bacteroidota was found to be decreased in CRC patients (p = 0.027). Potential biomarker candidates identified included Enterococcus faecium, Ruminococcus bicirculans, Enterococcus gilvus, Enterococcus casseliflavus, Segatella oris, and Akkermansia muciniphila. Serum zonulin levels were higher in CRC patients (CRC = 70.1 ± 26.14, Control = 53.93 ± 17.33, p = 0.048). There is a significant relationship between gut microbiota and CRC. A multifactorial evaluation of this relationship could shed light on potential biomarker identification and the development of new treatment options for CRC.
Correlation in the change of gut microbiota with clinical periodontal parameters in grade C periodontitis patients after non-surgical periodontal therapy Elif Mutafcilar Velioglu, Uğur Arslan, Seyit Ali Kayis, Salih Maçin, Nobuhiko Kamada, Sema Hakki Journal of Medical Microbiology, 2025 Introduction. Intestinal dysbiosis is associated with systemic health, and approaches targeting the microbiome can influence the host. Oral and intestinal microbiota are interrelated; therefore, we aimed to determine whether non-surgical periodontal treatment (NSPT) affects systemic health through its impact on the intestinal microbiota. Hypothesis/Gap Statement. Although the association between oral and gut microbiota has been suggested, there is limited evidence regarding how periodontal therapy may influence intestinal microbial composition. We hypothesized that NSPT in patients with periodontitis would lead to favourable changes in the gut microbiome, which may parallel improvements in clinical periodontal parameters. Aim. This study aimed to investigate the effect of NSPT on both oral and intestinal microbiota and to evaluate whether changes in gut microbial composition correlate with periodontal clinical outcomes. Methodology. Five systemically healthy individuals with grade C periodontitis and five systemically and periodontally healthy individuals were included. Saliva and stool samples were collected at baseline and 1 month after NSPT. DNA extractions were performed and subjected to 16S ribosomal RNA gene sequencing on the Illumina Novaseq at the V3–V4 hypervariable regions. Results. Grade C periodontitis patients displayed distinct oral and gut microbiomes compared to healthy individuals. NSPT resulted in a reduction in the diversity of both saliva and stool samples in healthy individuals (P>0.05). Salivary Fusobacteriota levels (P<0.05) and the gut Firmicutes/Bacteroides ratio decreased after NSPT. Moreover, changes in gut microbiota significantly correlated with improvements in periodontal probing depth and clinical attachment level in periodontitis patients. Conclusion. The improvement in clinical periodontal parameters after NSPT correlates with a positive shift in the gut microbiome towards health. Although the number of participants was limited, these findings support a strong relationship between periodontal and gut status. Further studies with larger cohorts and long-term follow-up are required to confirm these results.
Relationship Between Idiopathic Granulomatous Mastitis and AB0 Blood Groups Fatih Türkoğlu, Hande Köksal, Uğur Arslan, Eray Balcı, Kübra Güllü, Mahmut Çınar Gazi Medical Journal, 2025 Objective: This study aimed to evaluate whether the A, B and 0 blood groups (AB0) subgroup distribution of patients with idiopathic granulomatous mastitis (IGM) is different or notdiffers from that of the general population. Methods:The patients with IGM who were followed up in the breast unit and applied for routine control between July 2021 and October 2021 were included in the study.Results: During this period, 101 IGM patients were enrolled.The patients' age ranged between 21 and 61 years (median, 33 years).The most common AB0 blood subgroup in both the patient and control groups was Group A (48.5% and 44.7%, respectively).Between the groups, the difference in AB0 subgroups was not statistically significant (p=0.122).Eight patients had erythema nodosum.In 75% of patients with erythema nodosum, the most common AB0 subgroup was Group A. Eight patients developed relapses.The AB0 subgroup was A in five of the patients who had a relapse.However, the comparison of AB0 subgroups according to both erythema nodosum and relapse status could not be performed because there were few such cases, and the data did not satisfy the necessary assumptions for the chi-square test. Conclusion:In our study, the AB0 blood group distributions in both patient and control groups were similar, and our data did not support a relationship between IGM and AB0 blood groups.
Antimicrobial, Optical, and Mechanical Properties of Saliva-Contaminated Silver–Zeolite Nanoparticle-Incorporated Dental Acrylic Resins Çisel Kısa Yaman, Necla Demir, Uğur Arslan, Nurullah Çiftçi Inorganics, 2024 Background and Purpose: This study aimed to evaluate the flexural strength, color change and antimicrobial effect of silver–zeolite nanoparticles (NPs) in acrylic resin materials. Methods: Fifty-six disc-shaped acrylic resin samples were divided into four groups (n = 7) according to concentrations of silver–zeolite NPs (0%, 2%, 4%, 5%). Discs were contaminated with C. albicans and S. mutans. The antimicrobial effect was tested by inoculating contaminated discs on Tryptic soy agar (TSA), Sabouraud Dextrose Agar (SDA), Tryptic soy broth (TSB), and Sabouraud dextrose broth (SDB). Forty rectangular 65 × 10 × 2.5 mm acrylic resin specimens were also classified into four groups (n = 10) according to concentrations of silver–zeolite NPs. For the color change, L, a, and b values of rectangular specimens were examined with a spectrophotometer. A three-point bending test was also performed using a Devotrans device to determine the flexural bond strength of rectangular specimens. Scanning electron microscope analysis (SEM/EDX analysis) was also performed. Results: In this study, the antimicrobial effect increased with the concentration of silver–zeolite NPs added to acrylic resin discs. In our study, adding 2% silver–zeolite NPs was more effective against C. albicans. The antimicrobial effect against S. mutans increased with concentration of silver–zeolite NPs (<0.001). The colonization of C. albicans was significantly reduced by silver–zeolite NPs. A significant increase was observed in the color change as the nanoparticle percentage ratio increased (p < 0.001). The flexural strength values of the groups containing 2% and 4% nanoparticles were found to be clinically acceptable. Conclusions: The study showed that bacterial and fungal colonization is significantly reduced by adding silver–zeolite nanoparticles to acrylic resin discs. Based on its antimicrobial, physical, and mechanical properties, we recommend adding 2% silver–zeolite nanoparticles to the acrylic resin material for optimal results.
