The aqueous extract of Phyllanthus amarus Schum & Thorn, was selected for preliminary phytochemical and antibacterial activity against human pathogens. Minimum inhibitory concentration was performed by broth dilution method and the zone of inhibition was studied by agar disc diffusion method at concentrations of 10 and 20 mg/ml in DMSO (Dimethyl Sulfoxide). The results revealed the antimicrobia...

The antibacterial activities of three new penems with 4-hydroxyprolinamide, 1-prolinamide and N-methyl-N-2-propionamide substituents, respectively, in position 2 and of their stereoisomers were examined against Staphylococcus aureus, Enterococcus faecalis, Enterococcus faecium, Escherichia coli and Pseudomonas aeruginosa. All substitutes conferred a broad antibacterial spectrum on the penem moi...

Rubus parvifolius L. (Rp) is a medicinal herb that possesses antibacterial activity. In this study, we extracted the volatile oil from the leaves of Rp to assess its antibacterial activity and analyze its chemical composition. A uniform distribution design was used to optimize the extraction procedure, which yielded 0.36% (w/w) of light yellowish oil from the water extract of Rp leaves. We foun...

i ntroduction: due to the complex anatomy of the root canal system and high surface tension of common root canal irrigants (rci), conducting an investigation on rcis containing surfactants is a priority. the aim of this in vitro study was to verify the antibacterial potential of rci with low surface tension in root canals infected with enterococcus faecalis ( e. faecalis ). methods and material...

abstract       background and objective: enterococci are relatively nonvirulent bacteria that rarely cause disease. antimicrobial treatment of enterococci is often challenging due to their antibiotic resistance. this study aimed to investigate the antibacterial activity of aqueous extract of garlic against enterococcal isolates.     methods: in this descriptive study, 120 enterococcus isolates ...

Objective: This study observed the antibacterial, antifungal (aquatic and pathogenic fungi), and anthelmintic properties of Lactobacillus plantarum (LP) KP894100 and Lactobacillus acidophilus (LC) KP942831, isolated from a dairy product. Methods: Lactic acid bacteria traditionally used to improve human health. For in vitro antibacterial, antifungal, and antihelminthic studies of intracellular c...

Aim. The purpose of this in vitro study was to assess the antimicrobial efficacy of Biopure MTAD against E. faecalis in contaminated root canals. Materials and Methods. Forty-two single rooted extracted human teeth were inoculated with E. faecalis and incubated for four weeks. The samples were divided in two control and five experimental groups irrigated with 1.5% sodium hypochlorite solution (...

OBJECTIVE The purpose of this study was to assess the in vitro effect of ascorbic acid on the antibacterial substantivity of Tetraclean in bovine root dentin pretreated with sodium hypochlorite (NaOCl). MATERIALS AND METHODS Eighty dentin tubes prepared from bovine incisor teeth were infected with Enterococcus faecalis for 14 days. The specimens were divided into five groups as follows: Tetra...

     White spot lesions are observed in nearly 50% of patients undergoing orthodontic treatment. Long-lasting antibacterial properties of orthodontic cements can reduce this phenomenon. The aim of this research was to compare antimicrobial activity of three commercial glass ionomer cements with three commercial zinc phosphate cements, over time, against streptococcus mutans and candida albicans...
