Dental caries occurrence is caused by the colonization of oral microorganisms and accumulation of extracellular polysaccharides synthesized by Streptococcus mutans with the synergistic influence of Lactobacillus spp. bacteria. The aim of this study was to determine ex vivo the antibacterial properties of ethanol extract of propolis (EEP), collected in Poland, against the main cariogenic bacteri...

BACKGROUND Preterm prelabour rupture of the fetal membranes (PPROM) precedes 30% of preterm births and is a risk factor for early onset neonatal sepsis. As PPROM is strongly associated with ascending vaginal infection, prophylactic antibiotics are widely used. The evolution of vaginal microbiota compositions associated with PPROM and the impact of antibiotics on bacterial compositions are unkno...

1. Risk of lactobacillus infection in critically ill adults receiving lactobacillus probiotics. Zach Ruege, Pharm.D.; UGA College of Pharmacy, Augusta, GA INTRODUCTION: Probiotics have been advocated in critically ill patients to mitigate risk for developing Clostridium difficile infection and ventilator associated pneumonia. Critically ill patients display suppressed immune response of the int...

Puba or carimã is a Brazilian staple food obtained by spontaneous submerged fermentation of cassava roots. A total of 116 lactobacilli and three cocci isolates from 20 commercial puba samples were recovered on de Man, Rogosa and Sharpe agar (MRS); they were characterized for their antagonistic activity against foodborne pathogens and identified taxonomically by classical and molecular methods. ...

Lactic acid bacteria are generally believed to have positive roles in maintaining good health and immune system in humans. A number of Lactobacilli spp. are known to produce important metabolites, among which biosurfactants in particular have shown antimicrobial activity against several pathogens in the intestinal tract and female urogenital tract partly through interfering with biofilm formati...

Aim: The aim of this study was to determine the dependency of secretory immunoglobulin A (S-IgA) on the risk markers of the oral environment, such as the quality of the saliva, the dental biofilm, the oral Candida and Lactobacillus spp. in children. Methods: The study was conducted on a total of 116 children who were divided into four groups, which were: diabetes, asthma, orthodontic appliances...

Weaned piglets were fed diets containing 57 (low) or 2425 (high) mg kg(-1) analytical grade ZnO for a period of 5 weeks. Intestinal contents were sampled in weekly intervals and analyzed for bacterial cell numbers and main bacterial metabolites. The most severe effects of high dietary zinc were observed 1 week after weaning in the stomach and small intestine. Pronounced reductions were observed...

OBJECTIVE The aim of this study was to assess the microbial changes in children with fixed orthodontic appliances compared with a control group of children without orthodontic treatment. MATERIAL AND METHODS Ninety-five children, aged between 12 and 16 years, participated in this study. Forty-eight subjects were fitted with fixed orthodontic appliances and forty-seven were free of any such ap...

Background: Gastronomic natural flavors and spices have been used as both flavoring agents preservatives in food preparation for many years. They also utilized medical field their biological properties shown previous studies. Objective: The study aimed to evaluate the inhibitory effect of oil extracts from Cloves, Thyme, Cinnamon compared with ampicillin on some oral bacteria (Staphylococcus au...
