The present study was carried out to determine the phytochemical profile and antibacterial activity of Andrographis paniculata and Datura metel extracts. For the present investigation, extracts of A. paniculata and D.metel were prepared by extraction in methanol, chloroform, acetone and benzene and were compared for their antibacterial activity. The antibacterial activities were assessed by mea...

Cecropin is a cationic antibacterial peptide composed of 35-39 residues. This peptide has been identified as possessing strong antibacterial activity and low toxicity against eukaryotic cells, and it has been claimed that some types of the cecropin family of peptides are capable of killing cancer cells. In this study, the host effect of cloning antibacterial peptide cecropinB2 was investigated....

INTRODUCTION The purpose of this study was to compare the inhibitory effect of heat-killed Candida albicans and dentin powder on the antibacterial activity of chlorhexidine (CHX) against Enterococcus faecalis and Streptococcus sanguis. MATERIALS AND METHODS The antibacterial effect of each group was determined by measuring the zone of inhibition diameter in millimeters after incubation at 37°...

Previously, we reported antibacterial activity in the body fluid of the nematode Ascaris suum (Kato, Y. (1995) Zool. Sci. 12, 225-230). The antibacterial activity is due to a heat-stable and trypsin-sensitive molecule that was designated as ASABF (A. suum antibacterial factor). In the present study, the purification, determination of primary structure, and cDNA cloning of ASABF were carried out...

A main objective of the present study was to isolate and identify the antibacterial activity of actinomycetes strains obtained from terrestrial habitat and to utilize the antibacterial production profitably for the eradication of pathogens which cause disease to human being. The actinomycetes strains were isolated from terrestrial soil sample of King Saud University, Riyadh, Kingdom of Saudi Ar...

BACKGROUND Peroxide-producing lactobacilli provide protection from infection for the female reproductive tract. However, in vitro studies demonstrated that H2O2-produced by Lactobacillus is not the cause of inhibition of pathogens. It is not exactly known how H2O2-producing lactobacilli are involved in the protection of the vaginal environment. OBJECTIVES This study aimed to evaluate the impo...

OBJECTIVE To examine the in vitro antibacterial activity of the ethanol extract of fresh fruits of Solanum incanum L., fresh leaves of Ricinus communis L. and Allium ampeloprasum var. porrum L., and to determine and quantify the phenol compounds of the investigated plant parts. METHODS This study was carried out at the Faculty of Science, King Khalid University, Abha, Kingdom of Saudi Arabia ...

This study was carried out with an objective to investigate the antibacterial and antifungal potential of leaves of Cordia macleodii and Leucas ciliata. Antibacterial activity of ethanolic extracts of the leaves was carried out against three Gram negative bacteria – Escherichia coli, Klebsiella pneumoniae and Pseudomonas aeruginosa and two Gram positive bacteria – Bacillus Subtilis and Staphylo...

Essential oils present a fine antibacterial performance against a variety of bacteria. The main component of the cinnamon oil was eugenol (75.52%). In this study, the goal was to evaluate the antimicrobial activity and reveal bactericidal mechanism of cinnamon oil. Firstly, the minimum inhibitory concentration (MIC) and the minimum bactericide concentration (MBC) of cinnamon oil were tested. Th...

In this study, the forty Thai medicinal plants were used to screen the antibacterial activity against Campylobacter jejuni. Crude 95% ethanolic extracts of each plant were prepared. Antibacterial activity was investigated by the disc diffusion assay, and MICs and MBCs were determined by broth microdilution. The results of antibacterial screening showed that five plants have activity against C.j...
