Tracing probiotic producing bacterial species from gut of buffalo (Bubalus bubalis), South-East-Asia / Rastreando espécies bacterianas produtoras de probióticos de intestino de búfalo (Bubalus bubalis), sudeste da Ásia

Due to extensive application of antibiotics as growth promoters in animal feed, antimicrobial resistance has been increased. To overcome this challenge, rumen microbiologists search for new probiotics to improve the rate of livestock production. The present study was aimed to isolate and evaluate breed-specific lactic acid bacteria (LAB) as potential animal probiotics. The current study was conducted during 10 months from July 2020 to April 2021, in which a total of n=12 strains were isolated from different samples including milk, rumen, and feces of Nilli Ravi Buffaloes. These isolates were evaluated for their antimicrobial potential against common animal pathogens (Bacillus spp., E. coli, Staphylococcus aureus, Salmonella spp., Listeria spp.). All the isolates were identified using 16S rRNA gene sequencing and the phylogenetic analyses inferred that these strains showed close relations to the species of various genera; Enterococcus lactis, Pediococcus pentosaceus, Bacillus subtilis Weissella cibaria, Weissella soli, Bacillus tequilensis, Weissella bombi, Bacillus licheniformis, Lactococcus lactis, Bacillus megaterium, Lactobacillus ruminis, and Lactococcus lactis. NMCC-Ru2 has exhibited the enormous potential of antimicrobial activity, 28 mm, for Salmonella typhimurium;23 mm for Listeria monocytogenes 21 mm for E.coil. Highest resistance was seen in NMCC-Ru2 agasint test antbiotic, like 25.5 mm for Tetracycline. Overall results revesl that the probiotic profile of isolates was achieved using standard criteria, particularly with animal probiotic properties

Intraoral administration of probiotics and postbiotics: An overview of microorganisms and formulation strategies

Abstract The last decade provided significant advances in the understanding of microbiota and its role in human health. Probiotics are live microorganisms with proven benefits for the host and were mostly studied in the context of gut health, but they can also confer significant benefits for oral health, mainly in the treatment of gingivitis. Postbiotics are cell-free extracts and metabolites of microorganisms which can provide additional preventive and therapeutic value for human health. This opens opportunities for new preventive or therapeutic formulations for oral administration. The microorganisms that colonize the oral cavity, their role in oral health and disease, as well as the probiotics and postbiotics which could have beneficial effects in this complex environment were discussed. The aim of this study was to review, analyse and discuss novel probiotic and postbiotic formulations intended for oral administration that could be of great preventive and therapeutic importance. A special attention has been put on the formulation of the pharmaceutical dosage forms that are expected to provide new benefits for the patients and technological advantages relevant for industry. An adequate dosage form could significantly enhance the efficiency of these products.

Use of probiotics and similar in pediatric patients with Type 1 Diabetes Mellitus: a systematic review / Uso de probióticos e similares em pacientes pediátricos com Diabetes Mellitus tipo 1: uma revisão sistemática

ABSTRACT Objective: To perform a systematic review of randomized controlled trials, evaluating the effect of probiotics, prebiotics or symbiotics supplementation on glycemic and inflammatory control in children with Type 1 Diabetes Mellitus (T1DM). Data source: The Medical Literature Analysis and Retrieval System Online (MEDLINE/PubMed), Clinical Trials, Literatura Latino-Americana e do Caribe em Ciências da Saúde (LILACS) and Scientific Electronic Library Online (SciELO) databases were searched. Randomized clinical trials of pediatric patients with DM1 using probiotics, prebiotics or symbiotics were included, regardless of year or language of publication. Studies that did not evaluate glycated hemoglobin (HbA1c) were excluded. Metabolic results (HbA1c, total insulin dose and C-peptide) and inflammatory control [interleukin-10 (IL-10), tumor necrosis factor-alpha (TNF-α) and interferon-gamma (IFN-γ)] during probiotic supplementation or similar, related to modification of the intestinal microbiota, were analyzed. PROSPERO ID: CRD42022384485. Data synthesis: Five studies were selected for a systematic review. Regarding metabolic markers, only one of the articles that analyzed HbA1c showed a significant decrease (p=0.03) in the intervention group. One study identified a reduction in the total dose of insulin and increased C-peptide levels. Regarding the evaluation of inflammatory parameters (IL-10, TNF-α, INF-γ), there were no statistical relevant modifications. Conclusions: Current data from the literature were not conclusive in identifying an improvement in glycemic control and did not observe changes in inflammatory parameters with the use of probiotics, prebiotics or symbiotics in pediatric patients with T1DM.

Microbiota intestinal y cólicos infantiles: ¿hay lugar para los prebióticos, probióticos y posbióticos? / Gut Microbiota and Infant Colic: is there a Place for Prebiotics, Probiotics, and Postbiotics?

El consumo de probióticos, prebióticos y posbióticos, o su combinación, puede contribuir a mantener una microbiota intestinal saludable ya que permite la regulación de su disbiosis en el caso de algunas enfermedades o trastornos, principalmente en los trastornos gastrointestinales funcionales (TGIF). El microbioma intestinal es protagonista esencial en la fisiopatología de los TGIF a través de sus funciones metabólicas y nutricionales, el mantenimiento de la integridad de la mucosa intestinal y la regulación de la respuesta inmunitaria. Las investigaciones realizadas hasta la fecha indican que los probióticos, prebióticos y posbióticos pueden tener efectos inmunomoduladores directos y clínicamente relevantes. Existen pruebas del uso de esta familia de bióticos en individuos sanos para mejorar la salud general y aliviar los síntomas en una serie de enfermedades como los cólicos infantiles. La colonización y establecimiento de la microbiota comienza en el momento del nacimiento; los primeros 2-3 años de vida son fundamentales para el desarrollo de una comunidad microbiana abundante y diversa. Diversos estudios científicos realizados mediante técnicas tradicionales dependientes de cultivo y más recientemente por técnicas moleculares han observado diferencias en las poblaciones bacterianas de bebés sanos y aquellos que sufren TGIF, estos últimos caracterizados por un aumento de especies patógenas y una menor población de bifidobacterias y lactobacilos, en comparación con los primeros. En tal contexto, se considera que la microbiota intestinal como protagonista en el desarrollo de esos trastornos, entre ellos los cólicos infantiles, a través de sus funciones metabólicas, nutricionales, de mantenimiento de la integridad de la mucosa intestinal y regulación de la respuesta inmunitaria. Esto ha abierto la puerta al estudio de la utilización de prebióticos, probióticos y posbióticos en el tratamiento y/o prevención de los TGIF infantiles. El parto vaginal y de término así como la lactancia son fundamentales en la constitución de una microbiota saludable. Como herramientas de apoyo, existen estudios de eficacia que sustentan la administración de esta familia de bióticos, principalmente en los casos en que la lactancia no sea posible o esté limitada. (AU)

The consumption of probiotics, prebiotics, and postbiotics, or a combination of them, can contribute to maintaining a healthy intestinal microbiota as it allows the regulation of its dysbiosis in the case of some diseases or disorders, mainly in functional gastrointestinal disorders (FGIDs). The gut microbiome is an essential player in the pathophysiology of FGIDs through its metabolic and nutritional functions, the maintenance of intestinal mucosal integrity, and the regulation of the immune response. Research results thus far indicate that probiotics, prebiotics, and postbiotics may have direct and clinically relevant immunomodulatory effects. There is evidence regarding the prescription of this family of biotics in healthy individuals to improve overall health and alleviate symptoms in many conditions like infantile colic. The colonization and microbiota establishment begins at birth; the first 2-3 years of life are critical for developing an abundant and diverse microbial community. Several scientific studies performed by traditional culture-dependent techniques and more recently by molecular techniques have observed differences in the bacterial populations of healthy infants and those suffering from FGIDs, the latter characterized by an increase in pathogenic species and a lower population of bifidobacteria and lactobacilli, compared to the former. In this context, the intestinal microbiota plays a leading role in the onset of these disorders, including infantile colic, through its metabolic and nutritional functions, maintenance of the integrity of the intestinal mucosa, and regulation of the immune response. That has opened the door to the study of prebiotics, probiotics, and postbiotics usage in the treatment and or prevention of infantile FGIDs. Vaginal and term delivery and breastfeeding are fundamental in the constitution of a healthy microbiota. As supportive tools, there are efficacy studies that support the administration of this family of biotics, mainly in cases where lactation is not possible or is limited.

Probióticos y prebióticos en pacientes con enfermedad celíaca y sensibilidad al gluten no celíaca / Probiotics and prebiotics for patients with celiac disease and non-celiac gluten sensitivity

La enfermedad celíaca y la sensibilidad al gluten no celíaca han tenido un aumento en su incidencia, esto las ha convertido en tema de interés en la búsqueda de enfoques terapéuticos innovadores que ayuden a mejorar los síntomas intestinales y extraintestinales. Esta revisión pretende determinar los efectos del uso de probióticos y prebióticos en la enfermedad celíaca y sensibilidad al gluten no celíaca. Se realizó una búsqueda en bases de datos HINARI, PubMed y Scopus en idioma español e inglés, se incluyeron artículos originales y de revisión con un máximo de cinco años desde su publicación. El uso de probióticos y prebióticos para la enfermedad celíaca ha mostrado beneficios restaurando la composición del microbiota intestinal, en especial con el uso de Lactobacilli y Bifidobacterium spp.; en la sensibilidad al gluten no celíaca, el uso se ve limitado al no conocer con exactitud su fisiopatología; no obstante, se propone como mejor pauta terapéutica una dieta libre de gluten. El uso de probióticos y prebióticos podría aliviar los síntomas gastrointestinales y mejorar la disbiosis en pacientes con enfermedad celíaca y sensibilidad al gluten no celíaca. Sin embargo, se necesitan más estudios que evidencien los beneficios de su uso como alternativa terapéutica

Celiac disease and non-celiac gluten sensitivity are entities that have shown an increase in incidence, making them a topic of interest to provide innovative therapeutic approaches and improve intestinal and extraintestinal symptoms. This review intends to determine the effects of the use of probiotics and prebiotics in celiac disease and non-celiac gluten sensitivity. A narrative review was undertaken by searching for original and review articles no older than five years since publication through data bases consulted: HINARI, PubMed and Scopus in Spanish and English. The use of probiotics and prebiotics in celiac disease has shown benefits by restoring the composition of the intestinal microbiota, especially with the use of Lactobacilli and Bifidobacterium spp.; in non-celiac gluten sensitivity, its use is limited as its pathophysiology is not exactly known, therefore, a gluten-free diet is currently considered to be the best therapeutic guideline. The use of probiotics and prebiotics could alleviate gastrointestinal symptoms and improve dysbiosis in patients with celiac disease and non-celiac gluten sensitivity. However, more studies are needed to demonstrate the benefits of its use as a therapeutic alternative

Efficacy of Bacillus clausii in Pediatric Functional Constipation: A Pilot of a Randomized, Double-Blind, Placebo-Controlled Trial

Purpose: To evaluate the efficacy of Bacillus clausii in the treatment of pediatric constipation. Methods: A randomized, double-blind, placebo-controlled trial was conducted from January, 2021 to January, 2022 in children aged 1-5 years diagnosed with functional constipation according to Rome IV criteria. They were assigned to receive either B. clausii or placebo, once daily for four weeks. The primary out-come was treatment success (defined as ?3 spontaneous stools per week and stool consistency grade ?3 on Bristol stool chart). The secondary outcome was a comparison of stool frequency, consistency (defined by Bristol stool grade), and constipationrelated symptoms. Results: This trial enrolled 38 children (B. clausii, n=20 and placebo, n=18). At 4 weeks, no significant difference was noted in the treatment success between B. clausii and placebo groups [45% vs 56%; P=0.52). On within-group analyses, the mean (SD) of Bristol stool grade increased in both the B. clausii [1.7 (0.5) to 2.8 (1.2); P=0.003] and placebo [1.8 (0.5) to 2.8 (1.2); P=0.01] groups. Significant increases in the treatment success rate (22% to 56%, P=0.01) and mean stool frequency per week [3 (0.9) to 4.2 (1.7), P=0.01] were pronounced only in the placebo group. The frequency of painful defecation and large fecal mass were also significantly decreased in both the groups. No serious adverse events were observed. Conclusion: A 4-week course of B. clausii as the sole treatment was not more effective than a placebo for the management of functional constipation in children aged 1-5 years.

Dietary Immunomodulators - An Organic Boom in the Management of Chronic Diseases

Immunology involves all the defence mechanisms occurring in the body after the invasion of any infectious agent and the ability to resist this infection. The micronutrients like essential proteins, essential amino acids, vitamins (A, B6, B12, C, D, E and folic acid), fatty acids, minerals (iron, selenium, zinc and copper) and certain phytochemicals are of prime importance towards healthy immune system. In addition to these nutritional components, intestinal microflora and certain bacteria (probiotic bacteria) also play an important role in the modulation of healthy immune system. There is an ongoing trend of usage of immunomodulators to combat various chronic diseases like viral diseases, cancers, inflammatory and autoimmune diseases. This review focuses on various immunomodulators available in daily dietary meals, its positive and negative effects on immune system and its role in management of chronic illness as an adjunct to other modalities to achieve positive health benefits with minimal side effects.

TO STUDY THE ROLE OF PROBIOTICS IN PREVENTING NECROTIZING ENTEROCOLITIS IN PRETERM AND LOW BIRTH WEIGHT NEONATES

Introduction: Necrotising Enterocolitis (NEC) is the most common gastrointestinal emergency in NICU, it is a life-threatening disease that occurs primarily in premature infants.1 Probiotics are the live microbial dietary supplements that when administered in adequate amount promotes health.2 In premature infants they are thought to improve the positive balance of colonizing bacteria that facilitate development of mucosal immunity and prevent the excessive in?ammation associated with NEC.3 The present study is a Prospective Observational study Methods and Materials: conducted in the NICU at Prathima Institute Of Medical Sciences, Karimnagar,Telangana. During the period of 2 years between December 2020 and November 2022. Neonates of <37 weeks of gestation and with birth weight <1500 gms admitted into NICU are included in the study. The selected neonates would be administered probiotic 2 million spores of Bacillus clausii ampules per day along with expressed mother's own milk daily till they reach full feeds (150ml/kg/day). These neonates were observed clinically, investigated and studied during their period of admission in NICU for the development of Necrotising Enterocolitis and also the morbidity and mortality of such neonates was studied. : In the present study, out of 50 Results neonates, 11 (22%) preterms developed NEC while 39 (78%) of them did not. This was found to be statistically signi?cant (p=0.01). Out of the 11 preterms, 1 (2%) belonged to ELBW while 10 (90%) belonged to VLBW. Out of the 11 preterms who developed developed NEC, 4 (8%) developed stage I NEC, 5 (10%) developed stage II NEC and 2 (4%) developed stage III NEC. This was statistically signi?cant (p= 0.001) In our present study, 4 (8%) of the preterms developed with sepsis while 46 (92%) did not develop sepsis. This was statistically signi?cant (p=0.001) Necrotizing Enterocolitis is a worldwide problem in Conclusion: Preterms Low Birth Weight neonates. The present study has found that Probiotic supplementation has reduced both the 4incidence and severity of NEC in such neonates.

Effect of probiotic therapy on periodontal tissues and intestinal mucosa of rats with ligature-induced periodontitis / Efeito da terapia probiótica nos tecidos periodontais e mucosa intestinal de ratos com periodontite induzida por ligadura

INTRODUCTION: As periodontitis is caused by dysbiotic biofilm, it is believed that therapy with probiotics can act to control the mechanisms of adhesion and colonization, competing with invading microorganisms. OBJECTIVE: Evaluate probiotic therapy effect on periodontal tissues and intestinal mucosa of rats with ligature-induced periodontitis. METHODS: 32 Wistar rats were divided into four groups (n=8): Control Group (CG); Periodontal disease (PD); Probiotic (PROB); PD + probiotic (PDPRO). PD and PDPRO received a ligature over the first lower molars and PROB and PDPRO the probiotic Lactobacillus acidophilus based were given orally for 44 days. The animals were euthanized and the blood was collected for evaluation of triglyceride and cholesterol concentrations. The hemimandibles were collected for histomorphometric and radiographic analysis. The duodenum was removed for morphological evaluation and gingival tissue around the molars was collected for analysis of IL-17. RESULTS: The ANOVA one-way test was used followed by Tukey Test. PDPRO had a significantly lower bone loss than the PD (p<0.05) and a smaller number of osteoclasts on PDPRO when compared to the PD. As for IL-17, there was a decrease in the PDPRO when compared to the PD. The histomorphometry of the duodenum showed that there was a significant increase in the width of the villi in PROB only. CONCLUSION: The therapy with probiotics was effective to avoid the development of periodontitis by reducing alveolar bone loss and inflammation modulation and increasing the width of the duodenum villi, which may help to restabilize the balance of the gastrointestinal tract.

INTRODUÇÃO: Como a periodontite é causada por biofilme disbiótico, acredita-se que a terapia com probióticos possa atuar no controle dos mecanismos de adesão e colonização, competindo com microrganismos invasores. OBJETIVO: Avaliar o efeito da terapia probiótica nos tecidos periodontais e mucosa intestinal de ratos com periodontite induzida por ligadura. MÉTODOS: 32 ratos Wistar foram divididos em quatro grupos (n=8): Grupo Controle (GC); Doença periodontal (PD); Probiótico (PROB); PD + probiótico (PDPRO). PD e PDPRO receberam ligadura sobre os primeiros molares inferiores e PROB e PDPRO, o probiótico à base de Lactobacillus acidophilus dado via oral por 44 dias. Os animais foram sacrificados e o sangue coletado para avaliação das concentrações de triglicerídeos e colesterol total. As hemimandíbulas foram coletadas para análise histomorfométrica e radiográfica. O duodeno foi removido para avaliação morfológica e o tecido gengival ao redor dos molares foi coletado para análise de IL-17. RESULTADOS: Foi usado Teste ANOVA seguido pelo Teste de Tukey. PDPRO teve uma perda óssea significativamente menor do que o PD (p<0.05) e um menor número de osteoclastos no PDPRO quando comparado ao PD. Já para IL-17, houve diminuição do PDPRO em relação ao PD. A histomorfometria do duodeno mostrou que houve aumento significativo da largura das vilosidades no PROB somente. CONCLUSÃO: A terapia com probiótico foi eficaz para evitar o desenvolvimento de periodontite por reduzir a perda óssea alveolar e a modulação da inflamação e aumentar a largura das vilosidades duodenais, o que pode ajudar a estabilizar o equilíbrio do trato gastrointestinal.

Research progress on probiotics and short-term clinical outcomes in extremely premature infants / 中国小儿急救医学

The extremely premature infants have different degrees of immature organ development, abnormal intestinal flora establishment and low immune function, and are prone to necrotizing enterocolitis, late-onset sepsis and other complications.Probiotics can improve intestinal flora, and regulate cell metabolic activity and immune function.Probiotics can be used to prevent necrotizing enterocolitis, and late-onset sepsis and so on.However, the possible harm of probiotics to extremely premature infants should not be ignored.This review summarized the effects of probiotics on extremely premature infants.

Gut-lung axis: The crosstalk between gut microbiota and lung / 中国小儿急救医学

Human gut is a huge microbial habitat.Gut microbiota provides nutrition for human body, regulates metabolism and intestinal epithelial development, and induces innate immunity, and has significant impacts on growth, development and aging.Gut microbiota is influenced by genetics, living environment or life pattern, diseases and other factors, and also interacts with organs of the whole body through various of ways.The lung and the large intestine have embryological homology, common mucosal immune system, secretory function and other modern biological basis.Gut microbiota not only regulates the function of the gastrointestinal tract, but also affects the health and disease of the respiratory system, forming the " gut-lung axis". Intestinal microecological mediation and regulation based on the theory of gut-lung axis has achieved beneficial effects on the prevention and treatment of respiratory tract infection, asthma, and other respiratory diseases.

Advances in intestinal flora and attention deficit hyperactivity disorder / 国际儿科学杂志

Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder in children, which can be characterized by hyperactivity and(or)impulsivity, inattention, or a combination.The etiology and pathophysiological mechanism of ADHD have not been clarified yet.More and more studies have shown ADHD has intestinal flora disorder, which may affect the occurrence and development of ADHD through microbiome-gut-brain axis (MGBA). Treatment strategies targeting gut microbiota, including probiotics and dietary therapies, are considered to be a novel and effective method for the prevention or treatment of ADHD.This article reviews the changes of intestinal flora and the progress of diet and probiotics in ADHD children, in order to provide new ideas for treatment of ADHD children.

Advances in breast milk-derived probiotics / 国际儿科学杂志

Breast milk is the best source of nutrition for infants, and the microbial communities contained in breast milk can regulate the colonization of bacteria in the intestines of newborns and enhance their immunity.As microbial culture, isolation and identification techniques continue to evolve, more and more breast-milk-derived probiotics are being discovered.Common probiotics in breast milk include Lactobacillus, Bifidobacteria, Philococcus, Streptococcus thermophilus, etc.A large number of studies have proved that breast milk-derived probiotics have a certain role in the treatment of infantile colic, functional constipation, diabetes, mastitis and other diseases, and the natural source of breast milk probiotics, adapted to the milk matrix and other characteristics make it stand out from a group of probiotics.The discovery of probiotics isolated from breast milk and the exploration of their probiotic functions can not only provide an experimental basis for the addition of breast milk-derived probiotics to infant formula, but also provide new prospects for the treatment of various diseases.

Research Progress on Role of Probiotic Akkermansia Muciniphila in Oncogenesis, Development and Treatment of Tumor / 肿瘤防治研究

Although tumor treatment models have been continuously improved in clinical practice, cancer remains a serious threat to human health. The effect of probiotics on tumor therapy has received extensive attention. As a common colonizer of the intestinal mucosa, Akkermansia muciniphila(AKK) has a well-defined role in metabolic diseases, but its complex role in tumor development and therapeutic efficacy has not been fully elucidated. The unique properties and physiological roles of AKK play an important role in different solid tumors and it may be a potential biomarker. This article provides a review of previous studies and proposes clinical strategies to influence the abundance of AKK to provide a theoretical reference for the development of next-generation probiotics and the reshaping of the tumor treatment landscape.

Akkermansia Muciniphila Suppresses Non-alcoholic Steatohepatitis-associated Liver Cancer in Mice by Recovering Intestinal Barrier Function / 肿瘤防治研究

Objective To investigate whether the next-generation probiotics Akkermansia muciniphila can prevent non-alcoholic steatohepatitis (NASH)-related hepatocellular carcinoma (HCC). Methods We constructed a NASH-HCC model called STAM. STAM mice received oral saline or A. muciniphila starting at 4 weeks of age. Liver tissues were evaluated by HE staining and oil red O staining for NASH activity, and intrahepatic expression levels of inflammatory cytokines and ileal tight junction proteins were measured by RT-PCR. Results At 8 weeks of age, the steatosis, ballooning degeneration and NAS scores, TNF-α, MCP-1, IL-1β, and IL-6 mRNA expression were significantly decreased in the STAM+A. muciniphila group (both P < 0.05) compared with those in the STAM+saline group (all P < 0.05). At 20 weeks of age, the number of liver surface tumors formed, tumor size and IL-6 level were decreased in the STAM + A. muciniphila group (all P < 0.05). A. muciniphila restored the thickness of the colon mucosal layer and the number of goblet cells in STAM mice as well as increased the mRNA expression of the tight junction proteins ZO-1, Claudin-3, and Occludin in ileal epithelial cells. Conclusion Akkermansia muciniphila can inhibit the progression of NASH to HCC by improving the intestinal barrier function and may serve as a candidate drug to prevent NASH-HCC.
