this study was conducted to investigate the effect of bacillus subtilis and licheni formis on broiler breeder performance and gastrointestinal health of their progenies. a total of 336 broiler breeder hens (cobb 500) from 22 to 32 weeks of age were used in a completely randomized design of 2 × 2 factorial arrangement with four treatments, each with seven replicates. dietary treatments included:...

PURPOSE The prevalence of Candida infections has been rising with an increasingly aging population and a larger population of immunocompromised individuals. The use of probiotics may be an alternative approach to antifungal agents in the prevention and treatment of oral candidiasis. This study aimed to evaluate the short-term effect of probiotics in reducing the infection level of oral Candida ...

BACKGROUND In the past decade, the use of probiotic-containing products has been explored as a potential alternative in oral health therapy. A widely available probiotic drink, Yakult, was evaluated for oral health applications in this longitudinal study. Selected oral health parameters, such as levels and composition of salivary and tongue plaque microbiota and of malodorous gases, in dentate ...

The aim of this comprehensive review is to present an update about the current status of probiotics in terms of its application in the field of dentistry. The concept of administration of beneficial bacteria with a view to replace harmful microbes with useful ones has been revived by the probiotic concept. The main field of research has been in the gastrointestinal tract. However, past few year...

Probiotics or health-beneficial bacteria have only recently been introduced in dentistry and oral medicine after years of successful use in mainly gastro-intestinal disorders. The concept of bacteriotherapy and use of health-beneficial micro-organisms to heal diseases or support immune function was first introduced in the beginning of the 20th century. Later the concept lead to the development ...

Oral diseases, including dental caries and periodontitis, are among the most prevalent diseases worldwide and develop as a consequence of a microbial dysbiosis. Several bacterial strains are being tested as potential oral health-promoting organisms, but usually they are species isolated from niches other than the site where they must exert its probiotic action, typically from fecal samples. We ...

Probiotics have been advocated as a novel therapeutic approach to respiratory disease, but knowledge of how oral administration of probiotics influences the respiratory microbiota is needed. Using 16S rRNA amplicon sequencing of bacterial DNA our objective was to determine whether oral probiotics changed the composition of the upper and lower airway, rectal, and blood microbiota. We hypothesize...

Lactobacilli, like the other gut commensal bacteria, are well known for their use in poultry nutrition and for their probiotic properties. However, little is known about their interaction with the gastro-intestinal tract when administered in vivo. To specifically monitor the passage of lactobacilli after administered in hatchery, Lactobacillus plantarum was transformed with the recombinant vect...

total of 270 quail fertile eggs were set in hatchery. experimental groups including: negative control (neither received probiotic treatment nor challenged by salmonella), positive control (challenged by salmonella but not probiotic treatment) and 7 in hatchery administration methods: in ovo injection, spray, oral gavage, cloacal drinking (cloacal inoculation), cloacal drinking – in ovo injectio...

background: during the last two decades, significant advances have been made in the fields of lactococcal genetics and protein expression. lactococcus lactis (l. lactis) is an effective vector for protein expression and can be used as an antigen delivery system. hence, l. lactis is an ideal candidate for mucosal immunotherapy. profilin (che a 2), the major allergen in chenopodium album, is one ...
