ABSTRACT

Contextualização: Os probióticos constituem microrganismos vivos que, em quantidades adequadas, podem ser benéficos à saúde. Foram incorporados a produtos industrializados e suplementos e, atualmente, são amplamente utilizados. Entretanto, os efeitos podem ser diferentes em crianças e adultos, o que demanda cautela quanto à generalização de seus efeitos e a utilização exagerada. Objetivo: O presente estudo teve como objetivo avaliar as revisões sistemáticas desenvolvidas pela Cochrane no que concerne às intervenções com probióticos para crianças. Metodologia: Trata-se de overview de revisões sistemáticas Cochrane. Procedeu-se à busca por revisões sistemáticas na Cochrane Library. Foi utilizado o termo MeSH "probióticos". Os critérios de inclusão envolveram intervenções quaisquer com probióticos para crianças. Resultados: A estratégia de busca recuperou 56 revisões sistemáticas e, destas, 11 foram incluídas, diante dos critérios de inclusão e exclusão estabelecidos, totalizando 50.647 participantes avaliados a partir de 277 ensaios clínicos randomizados. Discussão: A maior evidência, em nível moderado, para o uso de probióticos em crianças encontra respaldo nas revisões sistemáticas Cochrane no que tange à prevenção da diarreia concomitante ao uso de antibióticos e na prevenção da diarreia causada por Clostridium. Para análise e qualificação de melhor nível de evidência de outros desfechos, é necessária a realização de novos ensaios clínicos de qualidade. Conclusão: A utilização de probióticos, amplamente recomendada atualmente, não tem efetividade tão promissora encontrada nas revisões sistemáticas Cochrane realizadas até esse momento.

ABSTRACT

Introducción. Existe evidencia del beneficio de los probióticos en prevenir enterocolitis necrotizante en prematuros extremos. Desde 2015, se usa probiótico preventivo en el Servicio de Neonatología, Hospital Hernán Henríquez Aravena, Temuco, Chile.Objetivo. Evaluar el impacto de este probiótico en la incidencia, gravedad, necesidad de terapia quirúrgica y letalidad por enterocolitis necrotizante en prematuros extremos. Pacientes y método. Estudio retrospectivo de cohortes. Datos analizados con Stata. Se aplicó la prueba exacta de Fisher para comparar porcentajes y, para los promedios, la prueba t para varianzas distintas. Los egresados entre 2015 y 2017 recibieron Lactobacillus reuteri Protectis (LRP), dosis única (1 x 108 unidades formadora de colonias) desde los primeros días de vida hasta cumplir las 36 semanas de edad gestacional corregida. Los controles egresados entre 2012 y 2014 no recibieron LRP.Resultados. El 3,45 % de los casos tuvo algún grado de enterocolitis: grado i (el 64 %), ii (el 18 %), iii (el 18 %); requirió cirugía el 18 % y no hubo letalidad. El 3,75 % de los controles históricos presentaron enterocolitis: grado i (el 12 %), ii (el 35 %), iii (el 53 %); el 64,7 % requirió cirugía, y el 47 % falleció. El grupo intervenido presentó grado ii o iii en un 36 %; en el grupo control, la sumatoria de estos estadios fue del 88 %.Conclusión.LRP administrado en dosis única diaria al prematuro extremo no modificó la incidencia de enterocolitis, pero disminuyó su gravedad, la letalidad y necesidad de tratamiento quirúrgico.


Introduction. There is evidence of the beneficial effects of probiotics to prevent necrotizing enterocolitis in extremely preterm infants. Probiotic prevention has been used since 2015 in the Division of Neonatology of Hospital Hernán Henríquez Aravena, Temuco, Chile.Objective. To assess the impact of this probiotic on the incidence, severity, surgical treatment requirement, and fatality rate of necrotizing enterocolitis in extremely preterm infants.Patients and methods. Retrospective, cohort study. Data were analyzed using Stata. Fisher's exact test was used to compare percentages, and the unequal variances t-test, for averages. Infants discharged between 2015 and 2017 received Lactobacillus reuteri Protectis (LRP), in a single dose (1 x 108 colony forming units), since the first days of life until 36 weeks of corrected gestational age. Controls discharged between 2012 and 2014 did not receive LRP.Results. Some degree of enterocolitis was observed in 3.45 % of cases: stage I (64 %), stage II (18 %), stage III (18 %); 18 % required surgery, and there were no deaths. Among historical controls, 3.75 % had enterocolitis: stage I (12 %), stage II (35 %), stage III (53 %); 64.7 % required surgery, and 47 % died. In the intervention group, stage II or III accounted for 36 % of cases, whereas in the control group, for 88 %.Conclusion. Administering a single daily dose of LRP to extremely preterm infants did not affect the incidence of enterocolitis, but reduced its severity, fatality rate, and surgical treatment requiremen

ABSTRACT

Introducción: En producción avícola el uso de antibióticos promotores del crecimiento es limitado, debido al incremento de resistencia bacteriana. Una alternativa evalúa los probióticos microencapsulados y su efecto en la salud intestinal. Objetivo: Determinar el efecto de Lactobacillus plantarum microencapsulado sobre parámetros intestinales e inmunológicos en pollos de engorde. Materiales y métodos: A 240 pollos Ross-308-AP de un día de nacidos se suministró alimento con o sin adición de probiótico bajo el siguiente modelo: sin probiótico-(T0), con probiótico comercial-(T1), con L. plantarum microencapsulado-(T2) y sin microencapsular-(T3). L. plantarum ATCC-8014 se microencapsuló mediante secado por aspersión, determinando su viabilidad en (%). Se evaluaron parámetros intestinales, morfo-histopatológicos e inmunológicos por Azul de Alcian, microscopia de barrido e inmunohistoquímica y la abundancia microbial por UFC/mL. Resultados: El microencapsulado confirió una viabilidad in vivo de L. plantarum del 88,1%. El tratamiento T2 mejoró los parámetros inmunológicos y confirió beneficios intestinales con una abundancia de bacterias benéficas (Lactobacillus) de (9,13x105-UFC/mL), significativamente mayor a la encontrada en los tratamientos T1 (8,91x105) y T3 (8,23x105) y el control T0 (9,18x104), (p<0,05). Conclusiones: La adición de L. plantarum microencapsulado en alimento para pollos mejora parámetros inmunológicos y confiere mayor abundancia de bacterias benéficas presentes en la microbiota intestinal.


Introduction: Usage of growth-promoting antibiotics in poultry production is limited due to the increase in bacterial resistance. An alternative to assess microencapsulated probiotics and their effect on gut health is presented in this study. Objective: To determine the effect of microencapsulated L. plantarum on intestinal and immunological parameters in broilers. Materials and methods: 240 Ross-308-AP chickens (one day old) were fed with or without the addition of a probiotic, under the following model: without probiotic (T0); with commercial probiotic (T1); with probiotic containing either microencapsulated (T2) or non-microencapsulated (T3) L. plantarum. ATCC-8014 was microencapsulated by spray drying, assessing its viability in (%). Alcian blue, scanning microscopy, and immunohistochemistry were used to evaluate intestinal, morpho-histopathological, and immunological parameters. Microbial abundance was quantified by UFC/ml. Results: Microencapsulation of L. plantarum induced an 88.1% in vivo viability. T2 treatment improved both immunological parameters and the intestinal population of beneficial bacteria (Lactobacillus) (9.13x105 UFC/ml), which was significantly higher than that found in T1 (8.91x105), T3 (8.23x105), and control T0 (9.18x104), (p<0.05). Conclusion: Adding microencapsulated L. plantarum to chicken feed improves immunological parameters and increases the population of beneficial bacteria in the intestinal microbiota.

ABSTRACT

In this case, a 12-year-old female domestic cat with chronic renal failure (CRF), which had lived longer than the mean survival time for cats with that condition, was monitored to evaluate the effects of treatment and mean gray value (MGV) changes. The cat has lived for nearly four years since the diagnosis. Probiotics have been used as an additional, classical supportive therapy since the beginning of treatment. The temporal changes in renal MGV were statistically evaluated in the last year of the four-year period. The cat had a comfortable existence and good body condition all her life and probiotic therapy may have had a positive influence post-CRF diagnosis. Ultrasonography (US) examination is a commonly used tool for monitoring the CRF situation, but it is not particularly sensitive. Therefore, MGV may be more useful for the quantitative evaluation of the extent of renal failure. Also, to the best of our knowledge, this is the first report for a long-term clinical evaluation of MGV in a cat with CRF. The aim of this case report was the evaluation of the relationship between MGV and clinical and biochemical changes in a cat with chronic renal failure.(AU)


No presente caso, uma gata doméstica de 12 anos com insuficiência renal crônica (IRC), que viveu mais do que o tempo médio de sobrevivência para gatos nessa condição, foi monitorada para avaliar os efeitos do tratamento e as alterações do valor cinza médio (MGV). A gata viveu quase quatro anos desde o diagnóstico. Os probióticos têm sido usados como uma terapia de suporte clássica adicional desde o início do tratamento. As alterações temporais do MGV renal foram avaliadas estatisticamente no último ano do período de quatro anos. A gata teve uma existência confortável e boas condições corporais durante toda a vida e a terapia com probióticos pode ter tido uma influência positiva após o diagnóstico de IRC. O exame de ultrassonografia (US) é uma ferramenta comumente usada para monitorar a situação da IRC, mas não é particularmente sensível. Portanto, o MGV pode ser mais útil para a avaliação quantitativa da extensão da insuficiência renal. Além disso, até onde se sabe, este é o primeiro relatório de uma avaliação clínica de longo prazo de MGV em um gato com IRC. O objetivo deste relato de caso foi avaliar a relação entre o MGV e as alterações clínicas e bioquímicas em um gato com insuficiência renal crônica.(AU)

ABSTRACT

Introducción: Los probíóticos de próxima generación son novedosa bioterapia activa surgida en el último decenio basados en bacterias comensales desconocidas, aisladas por métodos de biología molecular y que representan nuevo desafío para ser usadas en afecciones específicas relacionadas con severas alteraciones de disbiosis en la microbiota intestinal. Objetivo: Analizar las características de los candidatos a probióticos de próxima generación por sus mecanismos de acción y valor de su aplicación para el tratamiento de afecciones metabólicas y sistémicas específicas. Métodos: Se revisaron publicaciones en español e inglés en PubMed, Scimago, ScIELO, desde enero 2010 a julio 2020, se usaron los términos: probiótico de próxima generación, probióticos, microbiota intestinal, disbiosis. Resultados: Se actualizaron criterios sobre probióticos de próxima generación, concepto, mecanismos de acción, especificidades, resultados de investigaciones en ratones y limitados estudios en humanos en enfermedades específicas sistémicas y síndromes metabólicos, como obesidad, diabetes mellitus tipo 2, enfermedades inflamatorias intestinales y cáncer. Se revisaron antecedentes históricos, indicaciones como bioterapéuticos en enfermedades intestinales y rasgos diferenciales de probióticos de próxima generación con probióticos tradicionales. Consideraciones finales: Los conocimientos surgidos en el último decenio en estudios con bacterias comensales intestinales, no aisladas previamente, surgen como probióticos de próxima generación para bioterapia activa en el tratamiento de elección en alteraciones de disbiosis severa de la microbiota intestinal, asociadas a enfermedades específicas sistémicas que cursan con síndrome metabólico. Las evidencias experimentales abren promisorio camino para influir en mejoría o resolución de dichas afecciones(AU)


Introduction: Next-generation probiotics are novel active biotherapy that has emerged over the past decade based on unknown commensal bacteria, isolated by molecular biology methods and representing a new challenge to be used in specific conditions related to severe alterations of dysbiosis in the gut microbiota. Objective: Analyze the characteristics of next generation probiotic candidates due to their mechanisms of action and the value of their application for the treatment of specific metabolic and systemic conditions. Methods: Publications from January 2010 to July 2020 in Spanish and English were reviewed on PubMed, Scimago, ScIELO, and were used the terms: next generation probiotics, probiotics, gut microbiota, dysbiosis. Results: There were updated criteria on next-generation probiotics, concept, mechanisms of action, specificities, results of research in mice and limited human studies in specific systemic diseases and metabolic syndromes, such as obesity, type 2 diabetes mellitus, inflammatory bowel diseases and cancer. Historical background, indications such as biotherapeutics in bowel diseases and next-generation probiotic differential traits with traditional probiotics were reviewed. Final Considerations: Knowledge gained over the past decade in studies with non-previously isolated intestinal commensal bacteria emerges as next-generation probiotics for active biotherapy as the treatment of choice in severe intestinal microbiota dysbiosis alterations, associated with specific systemic diseases that lead to metabolic syndrome. Experimental evidence opens up promising path to influence improvement or resolution of such conditions(AU)

ABSTRACT

La leche materna provee microorganismos que colonizan el intestino y programan el sistema inmunológico para desarrollar tolerancia oral. Entre los 6 meses de lactancia materna exclusiva y los 2 años de lactancia prolongada recomendada, la alimentación complementaria conlleva una reducción progresiva en el ingreso de microorganismos vivos al ecosistema intestinal. Esto se debe a que los alimentos en general -a diferencia de la leche materna- o se encuentran desprovistos de microorganismos o, si los poseen, suelen inactivarse durante la cocción. Los alimentos fermentados y los probióticos podrían constituir una estrategia nutricional valiosa, dado que garantizarían la provisión de microorganismos vivos ante la reducción o interrupción anticipada de la lactancia. Los términos "alimentos fermentados" y "probióticos" no son sinónimos. La identidad microbiológica, la inocuidad y la existencia de estudios clínicos de eficacia para unos y otros son claves para entender sus diferencias y decidir una eventual recomendación alimentaria


Breast milk provides microorganisms that colonize the gut and program the immune system to develop oral tolerance. Between the 6 months of exclusive breastfeeding and the recommended 2 years of prolonged breastfeeding, complementary feeding leads to a progressive reduction in the entry of live microorganisms into the gut ecosystem. This is because foods in general -unlike breast milk- are devoid of microorganisms or, if present, they are often inactivated during cooking. Fermented foods and probiotics could be a valuable nutritional strategy, as they would ensure the supply of live microorganisms in the face of a reduction or early cessation of breastfeeding. The terms "fermented foods" and "probiotics" are not synonymous. Microbiological identity, safety, and the existence of clinical efficacy studies supporting both are key to understand their differences and decide on an eventual dietary recommendation

ABSTRACT

BACKGROUND: Vibrio species display variable and plastic fitness strategies to survive and interact with multiple hosts, including marine aquaculture species that are severely affected by pathogenic Vibrios. The culturable Vibrio sp. strain ArtGut-C1, the focus of this study, provides new evidence of such phenotypic plasticity as it accumulates polyhydroxybutyrate (PHB), a biodegradable polymer with anti-pathogen activity, particularly in the marine larviculture phase. The strain was isolated from the gut of laboratory-reared Artemia individuals, the live diet and PHB carrier used in larviculture. Its main phenotypic properties, taxonomic status and genomic properties are reported based on the whole-genome sequencing. RESULTS: Vibrio sp. ArtGut-C1 yielded 72.6% PHB of cells' dry weight at 25 C. The genomic average nucleotide identity (ANI) shows it is closely related to V. diabolicus (ANI: 88.6%). Its genome contains 5,236,997- bp with 44.8% GC content, 3,710 protein-coding sequences, 96 RNA, 9 PHB genes functionally related to PHB metabolic pathways, and several genes linked to competing and colonizing abilities. CONCLUSIONS: This culturable PHB-accumulating Vibrio strain shows high genomic and phenotypic variability. It may be used as a natural pathogen biocontrol in the marine hatchery and as a potential cell factory for PHB production.

ABSTRACT

@#Introduction Probiotics such as Saccharomyces boulardii are now advocated for the treatment of diarrhea. The objective of this systematic review and meta-analysis was to determine the effectiveness of Saccharomyces boulardii in the treatment of diarrhea. Methods MEDLINE, EBSCO, Clinical Key, and the Cochrane Library were searched for clinical trials which used Saccharomyces boulardii as primary or adjuvant treatment for diarrhea. Outcomes included were treatment success in the form of cessation of diarrhea, decrease in the duration of diarrhea, decrease in hospital days, and improvement of dehydration. The Centre for Evidence-Based Medicine Critical Appraisal tool together with the Cochrane Collaboration tool was used to assess the risk of bias, RevMan 5.4 for encoding, and the Mantel-Haenszel method for analysis to compute a pooled result. Results Eleven clinical trials involving 1,541 participants were included in the systematic review and meta-analysis. Seven studies showed a non-significant overall decrease in the duration of diarrhea of 1.65 days (p = 0.25), five studies showed an overall significant beneficial response (RR = 1.68, p < 0.001) in the cessation of diarrhea. There was a statistically significant mean decrease (1.01 days, p < 0.001) in duration of hospitalization; and a statistically significant decrease (0.18 days or 4.32 hours, p = 0.04) in the duration of vomiting. Conclusion A systematic review and meta-analysis of 11 clinical trials favors the use of Saccharomyces boulardii in the treatment of diarrhea in terms of cessation of diarrhea, decrease in the duration of hospitalization and duration of vomiting.

ABSTRACT

Abstract Objective The aim of this study was to evaluate whether probiotics multi-strain formula affects the development of apical periodontitis (AP) induced in rats. Methodology 16 Wistar rats were divided in two groups (n=8): rats with AP fed with regular diet (Control-C (CG)); rats with AP, fed with regular diet and supplemented with multi-strain formula (one billion colony-forming units (CFU)): GNC Probiotic Complex (PCG) ( Lactobacillus acidophilus, Lactobacillus salivaris, Lactobacillus plantarum, Lactobacillus rhamnosus, Bifidobacterium bifidum, Bifidobacterium animalis subs. lactis and Streptococcus thermofilus ). AP was induced in the upper and lower first molars by dental pulp exposure to the oral environment. PCG was administered orally through gavage for 30 days during the AP development. After this period the animals were euthanized and the mandibles were removed and processed for histologic analysis, and immunochemical assays for interleukin (IL)-6, IL-10, IL-1β, RANKL, OPG, and TRAP. The Mann-Whitney U test and Student's t test were performed (P<.05). Results The CG showed more intense inflammatory infiltrate than the PCG group (P<.05). IL-1β, IL 6 and RANKL decreased in the PCG group compared with CG (P<.05). The IL-10 level increased in the PCG group (P<.05). The OPG level was similar in both groups (P>.05). The number of mature osteoclasts (TRAP-positive multinucleated cells) was lower in PCG group when compared to the CG (P<.05). Conclusion Probiotic Complex modulates inflammation and bone resorption in apical periodontitis.

ABSTRACT

Abstract Plant based protein sources are one of the best, cost effective and easily available protein sources being used in fish feed. But due to a lower number of micro-biota in fish gut plant meal based diets cannot be digested and absorbed well in fish body. Probiotics were supplemented at 0, 1, 2, 3, 4 and 5 gkg-1 levels in fish feed for formulating one control and five test diets. In this study, three replicates of each treatment were used and number of fingerlings was 15 in each replicate. The C. carpio (common carp) fingerlings were fed at 5% of live wet weight on their prescribed diet twice daily. The results revealed that supplementation of probiotics in corn gluten meal based diets significantly (p<0.05) improved growth performance, carcass composition and hematological parameters. Most optimum values of growth performance parameters were noted at 2 gkg-1 level of probiotics supplemented diet. C. carpio fingerlings fed corn gluten meal based diet supplemented with 2 gkg-1 level of probiotics indicated significant (p<0.05) improvements in crude protein (17g) crude fat (9g) and gross energy (3 kcalg-1) whereas higher red blood cells (RBCs), white blood cells (WBCs) and hemoglobin (Hb) was also recorded in fish blood when fed 2 gkg-1 probiotics level diet. From these results, it was concluded that 2 gkg-1 probiotics supplementation in corn gluten meal based diet is optimum for improving growth performance, body composition and hematology of C. carpio fingerlings.

ABSTRACT

A associação de probióticos ao debridamento mecânico pode ser uma proposta de tratamento das doenças periodontais, em especial para pacientes portadores de Diabetes Mellitus tipo 2 (DM2). Avaliou-se os efeitos da administração do probiótico Lactobacillus reuteri como terapia coadjuvante no tratamento da Periodontite (P) associada ao DM2. Um total de 40 participantes diabéticos e diagnosticados com P foram randomizados em Grupo RAR+Placebo (n=20): receberam debridamento mecânico associado ao probiótico e Grupo RAR+Probi (n=20): tratados com debridamento mecânico associado a um placebo. Foram realizadas avaliações de profundidade de sondagem (P.S.), recessão gengival (RG), nível de inserção clínica (NIC), índice de placa (IP), índice de sangramento gengival (IG) e índice PISA no baseline, 30, 90 e 180 dias. Foi realizada dosagem da concentração de citocinas (INF-γ, IL-10, IL-12, IL-13, IL1ß, IL-4, IL-6, IL-8, TNF-α) do fluido crevicular gengival (FCG), no baseline e 180 dias após o tratamento. Informações sobre efeitos adversos do uso de medicamentos e sobre qualidade de vida foram coletadas. Os dados foram obtidos em média e desvio padrão, e analisados pelos testes Fridman/Tukey e MannWhiteny. Considerado a metodologia do presente estudo, os resultados obtidos apontam que o debridamento periodontal promoveu melhora significativa (p<0.05) nos parâmetros clínicos periodontais em ambos os grupos, mas o uso do probiótico não foi eficiente para resultados adicionais quando comparado com o placebo. A terapia periodontal interferiu nos níveis de citocinas do FCG, porém não se pode afirmar que o uso de probiótico apresenta o mesmo efeito(AU)


The association of probiotics with mechanical debridement may be a proposal for the treatment of periodontal diseases, especially for patients with type 2 Diabetes Mellitus (DM2). The effects of the administration of the probiotic Lactobacillus reuteri as an adjunctive therapy in the treatment of Periodontitis (P) associated with DM2 were evaluated. A total of 40 diabetic participants and diagnosed with P were randomized into Group RAR + Placebo (n = 20): received mechanical debridement associated with the probiotic and Group RAR + Probi (n = 20): treated with mechanical debridement associated with a placebo. Probing depth (P.S.), gingival recession (RG), clinical insertion level (NIC), plaque index (IP), gingival bleeding index (IG) and PISA index were performed at baseline, 30, 90 and 180 days. Measurement of the concentration of cytokines (INF-γ, IL-10, IL-12, IL-13, IL-1ß, IL-4, IL-6, IL-8, TNF-α) of the gingival crevicular fluid (FCG), at baseline and 180 days after treatment. Information on adverse effects of medication use and on quality of life was collected. The data were obtained in mean and standard deviation, and analyzed by the Fridman / Tukey and MannWhiteny tests. Considering the methodology of the present study, the results obtained point out that periodontal debridement promoted a significant improvement (p <0.05) in periodontal clinical parameters in both groups, but the use of probiotic was not efficient for additional results when compared with placebo. Periodontal therapy interfered with FCG cytokine levels, but it cannot be said that the use of probiotics has the same effect. Cytokines(AU)

ABSTRACT

Abstract Food supplements have been increasingly investigated. Probiotics have several benefits for human and animal health and selenium (Se) is widely recommended against oxidative stress. In this context, the aim of this study was to develop a low-cost bioprocess to produce a functional food product comprising both probiotic and Se accumulation. Yeast cells of Saccharomyces boulardii CCT 4308 were cultivated using sugarcane molasses as substrate. Optimization studies were performed to evaluate the best medium composition for biomass production and Se-accumulation in batch and fed-batch systems. Optimized conditions were defined with a medium composed of 150 g L-1 sugarcane molasses and 12 g L-1 yeast extract, with feeding of 100 g L-1 sugarcane molasses and 100 μg mL-1 of Se incorporation after 4 h and 10 h of fermentation, respectively, during 48 h in STR (stirred tank reactor). Best biomass production reached 14.52 g L-1 with 3.20 mg Se g-1 biomass at 12 h. Process optimization led to 4.82-fold increase in biomass production compared to initial condition. A final Se-enriched S. boulardii CCT 4308 biomass was obtained, which is comparable to commercial products. An alternative probiotic yeast biomass was efficiently produced as a new food-form of Se supplement in a sustainable process using an inexpensive agro-industrial residue.

ABSTRACT

ABSTRACT Over the last years, there is growing evidence that microorganisms are involved in the maintenance of our health and are related to various diseases, both intestinal and extraintestinal. Changes in the gut microbiota appears to be a key element in the pathogenesis of hepatic and gastrointestinal disorders, including non-alcoholic fatty liver disease, alcoholic liver disease, liver cirrhosis, inflammatory bowel disease, irritable bowel syndrome, and Clostridium difficile - associated diarrhea. In 2019, the Brazilian Society of Hepatology (SBH) in cooperation with the Brazilian Nucleus for the Study of Helicobacter Pylori and Microbiota (NBEHPM), and Brazilian Federation of Gastroenterology (FBG) sponsored a joint meeting on gut microbiota and the use of prebiotics, probiotics, and synbiotics in gastrointestinal and liver diseases. This paper summarizes the proceedings of the aforementioned meeting. It is intended to provide practical information about this topic, addressing the latest discoveries and indicating areas for future studies.


RESUMO Nos últimos anos, um volume crescente de evidências indica que os microrganismos estão envolvidos na manutenção da saúde humana e também estão relacionados a várias doenças, tanto intestinais quanto extraintestinais. Alterações na microbiota intestinal parecem ser um elemento chave na patogênese de doenças hepáticas e gastrointestinais, incluindo doença hepática gordurosa não-alcoólica, doença hepática alcoólica, cirrose hepática, doenças inflamatórias intestinais, síndrome do intestino irritável e diarreia associada ao Clostridium difficile. Em 2019, a Sociedade Brasileira de Hepatologia (SBH) em colaboração com o Núcleo Brasileiro para Estudo do Helicobacter pylori e Microbiota (NBEHPM) e a Federação Brasileira de Gastroenterologia (FBG) realizaram um encontro exclusivamente voltado para a discussão sobre microbiota e uso de prebióticos, probióticos e simbióticos em doenças hepáticas e gastrointestinais. Este texto resume os principais pontos discutidos durante o evento, e tem a intenção de fornecer informações práticas sobre o assunto, abordando as descobertas mais recentes e indicando áreas para estudos futuros.

ABSTRACT

Bacillus toyonensis is a probiotic microorganism that for decades has been used in animal nutrition around the world. The objective of this work was to evaluate the immunomodulatory effect of oral B. toyonensis supplementation in dogs vaccinated against canine parvovirus. Puppies were randomly selected and divided in two groups, one received B. toyonensis at a concentration of 2x10 8 viable spores per day and another group without supplementation was left as control. The puppies were vaccinated against canine parvovirus type 2. B. toyonensis supplementation was efficient in stimulating specific IgG for parvovirus with titers of 2, 3, and 2.5-fold higher than controls at 7, 21, and 35 pos-vaccination days respectively. Peripheral blood mononuclear cells (PBMCs) from dogs were cultured and stimulated with B. toyonensis DNA, vegetative cell and spores. The mRNA transcription of cytokines IL-4, IL-17, and IFN-γ up modulated by the stimuli. Thus, we conclude in this study that B. toyonensis supplementation may amplify the vaccine immune response against canine parvovirus.(AU)

Os filhotes foram selecionados aleatoriamente e divididos em dois grupos, um recebeu B. toyonensis na concentração de 2 × 10 8 esporos viáveis por dia e outro grupo sem suplementação como controle. Os filhotes foram vacinados contra o parvovírus canino tipo 2. A suplementação com B. toyonensis foi eficiente em estimular IgG específica para parvovírus com títulos de 2, 3 e 2,5 vezes maior que os controles aos 7, 21 e 35 dias pós-vacinação, respectivamente. Células mononucleares do sangue periférico (PBMCs) de cães foram cultivadas e estimuladas com DNA de B. toyonensis, células vegetativas e esporos. A transcrição do mRNA das citocinas IL-4, IL-17 e IFN-γ foi modulada pelos estímulos. Assim, concluímos neste estudo que a suplementação com B. toyonensis pode amplificar a resposta imune da vacina contra o parvovírus canino.(AU)

ABSTRACT

BACKGROUND: Cellulose as a potential feed resource hinders its utilization because of its complex structure, and cellulase is the key to its biological effective utilization. Animal endogenous probiotics are more susceptible to colonization in the intestinal tract, and their digestive enzymes are more conducive to the digestion and absorption of feed in young animals. Min pigs are potential sources of cellulase probiotics because of the high proportion of dietary fiber in their feed. In this study, the cellulolytic bacteria in the feces of Min pigs were isolated and screened. The characteristics of enzymes and cellulase production were studied, which provided a theoretical basis for the rational utilization of cellulase and high-fiber food in animal production. RESULTS: In our study, 10 strains of cellulase producing strains were isolated from Min pig manure, among which the M2 strain had the best enzyme producing ability and was identified as Bacillus velezensis. The optimum production conditions of cellulase from strain M2 were: 2% inoculum, the temperature of 35°C, the pH of 5.0, and the liquid loading volume of 50 mL. The optimum temperature, pH and time for the reaction of cellulase produced by strain M2 were 55°C, 4.5 and 5 min, respectively. CONCLUSIONS: Min pigs can be used as a source of cellulase producing strains. The M2 strain isolated from feces was identified as Bacillus velezensis. The cellulase from M2 strain had a good activity and the potential to be used as feed additive for piglets.

ABSTRACT

BACKGROUND: A key challenge for manufacturers of pro-health food containing active probiotic microorganisms is to develop a product with attractive sensory features along with maintenance of declared number of microorganisms during storage and transfer by alimentary tract. RESULTS: The highest concentration of polyphenols was observed in snacks without an additive of probiotics as well as those with an additive of L. rhamnosus and B. animalis bacteria and concentration of these compounds increased by 9.5% during six months of storage. None of the products distinguished itself in the sensorial assessment although each was assessed positively. The number of microorganisms was stable and comparatively high during six months of storage at a room temperature and in cooling conditions (108 cfu/g). In the digestion model, an influence of aggressive digestion conditions was examined in the alimentary tract on the number of microorganisms, which allowed to arrange strains from the most resistant (S. boulardii) to the most sensitive (B. breve). It must be noted that currently on the market there is no available snack containing probiotic yeast as well as there is no literature data on works on such formulation of food. CONCLUSIONS: In the newly developed snack made of chocolate, in which sugar has been replaced with maltitol, a raw material was added in the form of raspberry, prebiotic in the form of inulin and a strain of probiotic bacteria, including the unprecedented so far S. boulardii, which stands a high chance to occupy a good place on the market of functional food.

ABSTRACT

RESUMEN Los adultos mayores son especialmente vulnerables a sufrir enfermedades asociadas al tracto gastrointestinal, ya que el envejecimiento conlleva naturalmente a un desbalance en la diversidad y cantidad de los microorganismos presentes en el intestino. Por ello, la suplementación de su dieta con oligosacáridos y polisacáridos no digestibles (OPND) ha cobrado gran relevancia científica. Esto, con el propósito de prevenir y revertir, en parte, los cambios negativos en la microbiota intestinal derivados del envejecimiento. Se ha observado que la suplementación de OPND en adultos mayores genera variados beneficios, entre los que destacan una mejora en el sistema inmune, una mayor absorción de calcio, reducción en la incidencia de alergias, reducción de la constipación y una disminución en los niveles de glicemia y colesterol sanguíneos. Debido a que, los efectos del consumo de OPND en adultos mayores han sido escasamente discutidos en la literatura científica en idioma castellano, el propósito de esta revisión es abordar el tema haciendo énfasis en la realidad chilena y latinoamericana. Ello, con miras a fomentar la incorporación de OPND en alimentos y programas de alimentación dirigidos específicamente a personas de la tercera edad.


ABSTRACT Since aging naturally leads to an imbalance in the diversity and quantity of microorganisms present in the intestine, older people are particularly vulnerable to diseases associated with the gastrointestinal tract. Thus, supplementing the diet of elderly persons with non-digestible oligosaccharides and polysaccharides (OPND) has gained scientific relevance. Supplementation aims to prevent and (partially) revert the negative changes in intestinal microbiota due to aging. It has been observed that OPND supplementation in older adults provides several benefits, including an improvement in the immune system, increased calcium absorption, a reduction in the incidence of allergies, a reduction in constipation and a decrease in blood levels of cholesterol and glucose. Because the effects of OPND supplementation in older adults has been scarcely discussed in the scientific literature in the Spanish language, the purpose of this review is to address the issue with emphasis on the Chilean and Latin-American reality. The article promotes the incorporation of OPND in processed food and feeding programs specifically designed for older people in Latin America.
