          Abstract

          Objectives

          To characterize the adhesion ability of nine Helicobacter pylori strains and eight probiotics in human oral keratinocyte cells (H357 cells) in comparison to intestinal cells (Caco-2 and HIEC-6 cells). Subsequently, the anti-adhesion and co-aggregation abilities of the selected probiotic strains on H. pylori strains were investigated.

          Methods

          Nine H. pylori strains, including H. pylori ATCC43504 (type strain), and 8 clinical strains, were isolated from oral samples of three patients (one non-disease, one gastritis patient, and one gastric cancer patient). Eight selected probiotic strains were used, as follows: Lacticaseibacillus paracasei SD1, Lacticaseibacillus rhamnosus SD4 , L. rhamnosus SD11, Limosilactobacillus fermentum SD7, L. rhamnosus GG, Limosilactobacillus reuteri ATCC-PTA6475, Lacticaseibacillus casei Shirota, and L. paracasei CNCM I-1572. The adhesion and anti-adhesion abilities of H. pylori and the probiotic strains were investigated in H357, Caco-2, and HIEC-6 cells. Co-aggregation at various pHs, hydrophobicity, and surface receptors of the cell lines for H. pylori strains were examined.

          Results

          All probiotic and H. pylori strains adhered to H357 significantly better than Caco-2, and HIEC-6 cells. Three probiotic strains (SD7, SD4, SD11) showed significantly higher adhesion than others. Of the clinical H. pylori strains, isolates from a gastric cancer patient had the highest adhesion ability to all of the cell lines tested. Probiotic strains that exhibited high adhesion ability provided high anti-adhesion and co-aggregation against H. pylori strains. Acidic conditions encouraged the co-aggregation of probiotics to H. pylori strains.

          Conclusion

          This study provides information relating to the adhesion abilities of clinical H. pylori and probiotic strains to the oral mucosa when compared to the intestinal mucosa. Certain probiotic strains may be useful for the successful eradication of H. pylori infection via anti-adhesion and co-aggregation.

          أهداف البحث

          توصيف قدرة الالتصاق لتسع سلالات من الملوية البوابية وثمانية بروبيوتيك في خلايا الخلايا الكيراتينية الفموية البشرية (خلايا اتش٣٥٧) مقارنة بالخلايا المعوية (خلايا كاكو-٢ و خلايا هيك-٦). بعد ذلك، تم فحص القدرات المضادة للالتصاق والتجميع المشترك لسلالات الكائنات الحية المجهرية المختارة على سلالات الملوية البوابية.

          طرق البحث

          تسع سلالات من الملوية البوابية تضمنت الملوية البوابية أ،ت،س،س،٤٣٥٠٤ (سلالة من النوع)، وتم عزل ٨ سلالات إكلينيكية من عينات فموية لثلاثة مرضى (واحد غير مصاب، ومريض التهاب معدي، ومريض سرطان معدي). تم استخدام سلالات الكائنات الحية المجهرية الثمانية المختارة على النحو التالي: لاكتوباسيلس باراكاسي (اس دي1) و لاكتوباسيلس رامنوساس (اس دي4) و لاكتوباسيلس رامنوساس (اس دي11) و ليموسيلاكتوباسيلوس فيرمنتوم (اس دي7) و لاكتوباسيلس رامنوساس (ج ج) و ليموزيلاكتياز5؛ تم فحص قدرات التصاق الملوية البوابية وسلالات البروبيوتيك المضادة للالتصاق في خلايا اتش٣٥٧ وخلايا كاكو-٢ و خلايا هيك-٦. تم فحص التجميع المشترك عند مختلف الأس الهيدروجيني، والكراهية للماء والمستقبلات السطحية لخطوط الخلايا لسلالات الملوية البوابية.

          النتائج

          جميع سلالات الكائنات الحية المجهرية والملوية البوابية يمكن أن تلتصق بـ خلايا اتش٣٥٧ أفضل بكثير من خلايا كاكو-٢ و خلايا هيك-٦. أظهرت ثلاث سلالات بروبيوتيك (اس دي7 و اس دي4 و اس دي11) التصاق أعلى بكثير من سلالات أخرى. من بين سلالات الملوية البوابية السريرية، كان لعزلات مريض سرطان المعدة أعلى قدرة على الالتصاق لجميع سلالات الخلايا المختبرة. سلالات البروبيوتيك التي أظهرت قدرة عالية على الالتصاق، يمكن أن توفر مقاومة عالية للالتصاق وتجمع مشترك ضد سلالات الملوية البوابية. يمكن أن تشجع الظروف الحمضية تكتل البروبيوتيك لسلالات الملوية البوابية.

          الاستنتاجات

          تقدم هذه الدراسة معلومات عن قدرات التصاق الملوية البوابية وسلالات الكائنات الحية المجهرية في الغشاء المخاطي للفم مقارنة بالغشاء المخاطي المعوي. قد تكون سلالات معينة من الكائنات الحية المجهرية مفيدة في القضاء الناجح على عدوى الملوية البوابية عن طريق منع الالتصاق والتجميع المشترك.

          Helicobacter pylori treatment: antibiotics or probiotics

          Treatment of Helicobacter pylori infection is important for the management of gastrointestinal disorders such as peptic ulcer and gastric cancer. Due to the increase in the prevalence of H. pylori resistance to antibiotics, triple therapy with clarithromycin is no longer the best treatment for H. pylori, especially in some areas where the local resistance to this antibiotic is higher than 20%. Alternative treatments have been proposed for the eradication of H. pylori. Some of them including novel antibiotics or classical ones in different combinations; these treatments are being used in the regular clinical practice as novel and more effective treatments. Others therapies are using probiotics associated to antibiotics to treat this infection. The present article is a revision of H. pylori eradication treatment, focusing on emerging approaches to avoid the treatment failure, using new therapies with antimicrobials or with probiotics.

            Helicobacter pylori in human health and disease: Mechanisms for local gastric and systemic effects

            Helicobacter pylori ( H. pylori ) is present in roughly 50% of the human population worldwide and infection levels reach over 70% in developing countries. The infection has classically been associated with different gastro-intestinal diseases, but also with extra gastric diseases. Despite such associations, the bacterium frequently persists in the human host without inducing disease, and it has been suggested that H. pylori may also play a beneficial role in health. To understand how H. pylori can produce such diverse effects in the human host, several studies have focused on understanding the local and systemic effects triggered by this bacterium. One of the main mechanisms by which H. pylori is thought to damage the host is by inducing local and systemic inflammation. However, more recently, studies are beginning to focus on the effects of H. pylori and its metabolism on the gastric and intestinal microbiome. The objective of this review is to discuss how H. pylori has co-evolved with humans, how H. pylori presence is associated with positive and negative effects in human health and how inflammation and/or changes in the microbiome are associated with the observed outcomes.

              Adherence of human vaginal lactobacilli to vaginal epithelial cells and interaction with uropathogens.

              Three strains of Lactobacillus, identified as Lactobacillus acidophilus, Lactobacillus gasseri, and Lactobacillus jensenii, were selected from among 70 isolates from the vaginas of healthy premenopausal women for properties relevant to mucosal colonization or antagonism. All three self-aggregated and adhered to epithelial vaginal cells, displacing well-known vaginal pathogens, such as G. vaginalis, and inhibiting the growth in vitro of Escherichia coli and Streptococcus agalactiae. The surface components involved in self-aggregation appeared to be proteins for L. gasseri and lipoproteins for L. acidophilus and L. jensenii, as judged by susceptibility to treatment with appropriate degrading enzymes. The factors responsible for adherence to epithelial vaginal cells seemed to be glycoproteins (L. acidophilus and L. gasseri) and carbohydrate (L. jensenii). The receptors of the vaginal cells were glycolipids, which presumably were the targets of the competition observed between the lactobacilli and the pathogenic microbes.
