It is known that neuropeptide hormone oxytocin fundamental in human-canine social bonds regulates appetite and body weight. It was recently shown in mice that consuming Lactobacillus reuteri ATCC 6475 from human breast milk lowers body weight and up-regulates oxytocin levels in blood. Here we test the hypothesis that bacteria from dog saliva may similarly modulate recipient host body weight. We find that a Lactobacillus spp isolate from dog saliva led to lower body weight when fed to C57BL/6 wild type mice. Mice consuming the canineborne L. reuteri also had elevated oxytocin levels in blood plasma, and exhibited body weight in an oxytocin-dependent manner. Interestingly, killed (lysed) canine bacteria were sufficient to achieve the physiological effects. Taken together, these studies provide evidence that dog bacteria modulate oxytocin levels and body weight in recipient mice, and thus may help reduce risk of obesity in individuals cohabitating with pet dogs.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"23 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82816497","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Among the oral bacteria, streptococci especially Streptococcus mutans and Streptococcus salivarius are known as the most important microbial agents in dental caries and dental plaque. Dental caries treatment imposes heavy costs in all countries. Although there are different chemical antimicrobial agents for the prevention of of dental caries, but their important side effects have reported. Therefore, many attempts have done for finding alternative safe medications specially natural ingredients. The aim of this research is determination of antimicrobial effects of vinegar, rose water and green tea against four cariogenic bacteria.Methods: The antimicrobial effects of different concentrations of vinegar, rose water and green tea against Streptococcus mutans, Streptococcus salivarius, Streptococcus sanguis and Streptococcus salivarius are evaluated with disc diffusion, well plate and microtitre plate methods, also the effects of them against biofilm formation were studied.Results: The results showed vinegar, rose water and green tea significantly reduced biofilm formation of the streptococci. Vinegar and green tea decreased more then 70% the adhesion of streptococci but rose water decreased more then 70% of S. salivarius, more then 60% of S. sobrinus, S. sanguis and more then 50% of S. mutans adhesion. The diameter of highest inhibition zone was 24.2 mm for Streptococcus salivarius and 22 mm for Streptococcus salivarius against vinegar.The MIC of vinegar was for S. salivarius 0.0312 and MBC was 0.0625 (P<0.05), but the MIC of green tea for Streptococcus mutans and Streptococcus salivarius was 7.81 mg/ml and its MBC was 31.25 mg/ml which was significantly less than that for Streptococcus sanguis and Streptococcus salivarius which was 15.625 and 62.5 mg/ml, respectively (P<0.05). The MIC of rose water for Streptococcus salivarius, Streptococcus sanguis, Streptococcus salivarius was 1.Conclusions: This results indicated the potential capacity of vinegar, rose water and green tea for prevention or control of cariogenic streptococci proliferation.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"1 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89196021","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It is considered to be the most obvious sign of puberty in girls. It has been regarded in many cultures as a transitional step to womanhood. Nutrients are needed in varying amounts depending on one’s stage of growth. Objectives: Compare Anthropometric variation of Pre-menarcheal and post-menarcheal girls, Effect of body fat on menarcheal status. Study design: This study is done on adolescent counselling centre named anwesha clinic Anthrometric measurement are taken for this study. Method: Subjects: Adolescent school girls aged 10-19 years of Salboni Block of Paschim Medinipur the study area of Salboni Block is 25 km away from Medinipur town. Subjects are 10-19 years adolescent girl, the study were done on 1009 girls. Age at menarche of each girl was obtained by ‘status-quo’ method; with this method it is possible to collect menarche data for large representative samples of girls within a comparatively short period. Results: By comparison of Anthropometric variable it shows that post-menarcheal is higher anthropometric status. Mean difference in height, weight, MUAC, Triceps, Biceps, Fat Mass, Fat Free Mass, Body Mass Index, per cent body fat are 8.73, 3.69. 3.75, 1.56, 9.2.5.2, 4.99, 2.96, 2.41; they are significant comparison of pre-menache and post-menacheal anthropometric shows post-menarcheal girls’ anthropometric status is high. Higher per cent body fat girls experience early menarche Conclusion: Delayed menarche may be a sign of malnutrition since as nutritional status improves; the attainment of menarche is lowered. Attainment of menarche decreases when BMI increases. There is a correlation between BMI and attainment of menarche and also, there is a correlation between early obesity and early onset of menarche. Girls with early onset of menarche had higher BMI than those with late onset of menarche.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"6 1","pages":"1-3"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77493973","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Activation of platelets by probiotic lactic acid bacteria strains is considered as thrombotic initiative factor contributing to the development and progression of Lactobacillus endocarditis. The main purpose of the current study was to evaluate the immunologic enhancement effect of probiotic strains L. plantarum, L. acidophilus and L. rhamnosus on the activation of blood platelets. Whole fresh blood flow cytometry was used to measure p-selectin expression and fibrinogen binding at basal levels and following stimulation with platelet agonists and probiotic lactic acid bacteria strains. Platelet activation was determined by labelling with FITC-conjugated anti-human fibrinogen and phycoerythrin (PE)- conjugated anti-human CD62p before analysis by flow cytometry. Thrombin Receptor Activator Peptide-6 (TRAP-6) was used as positive control. The percentage of CD62p-positive platelets, FITC-conjugated and the light scatter profiles of the agonist-activated platelets were used to identify the occurrence and degree of platelet activation. Probiotic lactic acid bacteria strains included in this study did not show any effect on spontaneous activation of human blood platelets. These test strains also failed to exacerbate or diminish the platelet activation property when co-incubated with TRAP-6 platelet agonist. Hence, this is the first in vitro report showing the safety of a group of probiotic lactic acid bacteria in terms of their potential to contribute to the pathogenesis of infective endocarditic (IE), bacteremia symptoms or other thrombotic disorders and correlated cardiovascular complications by initiating the platelet activation.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"19 1","pages":"1-5"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84858149","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Prolonged L-Asparaginase intensification improved the outcome significantly. Nowadays L-Asparaginase is an essential drug that is used to treat children with Acute lymphoblastic leukemia all over the world. Its potential is now well established, as it has remarkably induced remission in most of the patients suffering with this disease. This therapy has brought a major breakthrough in modern oncology and with the development of its new functions, a great demand for L-Asparaginase is expected in the coming years. Keeping the potential of this particular enzyme in cancer treatment, the present work is planned with an intention of optimizing the production of L-Asparaginase both by conventional as well as by genetic engineering techniques. Pectobacterium carotovorum is selected for the present work based on its potentiality in cancer treatment and due to less glutaminase activity compared to the enzyme sourced from E. coli. Microbial culture was procured from MTCC, Chandigarh and screened for L-Asparaginase production in plate method and identified the activity based on the formation of pink color zone after overnight incubation.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"76 1","pages":"1-6"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89532680","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Upon birth, a well-balanced bacterial colonization of the infant gut has a profound impact on programming short and long term metabolic and immune homeostasis. Despite the fact that most of the causality is not yet fully understood, shift in the commensal gut microbial communities with implication to disease is often referred to as dysbiosis. Infants who tend to have a delayed and/or aberrant initial colonization with reduced microbial diversity and richness, whether induced by Caesarean section, premature delivery, or excessive use of perinatal antibiotics, could be more at risk for chronic health conditions associated with metabolic and immune disorders. Exploration of the long-term effects of this abnormal microbial number and diversity is critically needed in order to intervene early in the aberrant intestinal composition and restore numerous homeostatic systems (e.g. energy balance, glucose metabolism and immunity). Dietary manipulation of the gut microbiota through the so called ‘gut microbiota biomodulators’ (probiotics, prebiotics, synbiotics and postbiotics) represents a promising preventive avenue. This review aims to highlight factors that influence the gut microbiota soon after birth and discusses the potential gut-driven pathophysiologic pathways involved in intestinal dysbiosis and the gut microbiota-modulating effects of probiotics early in life.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"9 1","pages":"1-9"},"PeriodicalIF":0.0,"publicationDate":"2017-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89789153","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A series of In vitro tests that included survival in simulated gastrointestinal conditions (resistance to low pH, bile salts resistance and bile salts hydrolysis) and safety assessment (resistance to antibiotics, haemolytic and antimicrobial activity) were performed to select potential probiotic candidates, while Lactobacillus rhamnosus GG and Lactobacillus casei Shirota were used as reference strains. Initially, a total of 255 isolates of LAB have been recovered and screened for their survival in simulated gastrointestinal tract conditions and 133 isolates that exhibited moderate or good behavior in these tests were subsequently differentiated and characterized at species level with molecular tools. Pulsed Field Gel Electrophoresis was applied for strain differentiation, while species differentiation was based on restriction analysis of the amplified 16S rRNA gene. Specific multiplex PCR assay targeting the recA genes was applied to resolve the species level of the isolates, belonged to Lb. plantarum group. From the 133 isolates, 47 different strains were recovered and were assigned to Lactobacillus sakei(14), Lactobacillus curvatus (4), Leuconostoc mesenteroides (4), Lactococcus lactis (4), Lactobacillus casei group (1), Lactobacillus brevis (1), Lb. plantarum (10), Lb. pentosus (7) and Lb. paraplantarum (2). The identified strains with good behavior to the gastrointestinal tract tests were selected and further evaluated for their safety aspect. In conclusion, 19 out of the 47 identified strains were assessed as well-behaved, under simulated gastrointestinal conditions and also considered as safe, possessing thus desirable In vitro probiotic properties similar or better to that of the reference strains. These strains may be considered as good candidates for further investigation at in vivo and in situ studies to assess their potential health benefits and their performance as novel probiotic starters or adjunct cultures.","PeriodicalId":16865,"journal":{"name":"Journal of Probiotics & Health","volume":"109 1","pages":"1-8"},"PeriodicalIF":0.0,"publicationDate":"2016-11-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"85912216","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
