INTRODUCTION Due to an upsurge in antibiotic-resistant infections and lack of therapeutic options, new approaches are needed for treatment. Honey may be one such potential therapeutic option. We investigated the susceptibility of hospital acquired pathogens to four honeys from Wisconsin, United States, and then determined if the antibacterial effect of each honey against these pathogens is prim...

Licorice (Glycyrrhiza glabra L.) is an important medicinal plant. In this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. Bacillus subtilis, Enterococcus faecalis, Klebsiella pneumoniae, Pseudomonas aeruginosa, Staphylococcus aureus and Escherichia coli, and Candida albicans were used as test organisms...

The inhibitory effect of Ulva lactuca (Chlorophyta), Dilophus spiralis (Phaeophyta) and Jania rubens (Rhodophyta) marine algae species has been evaluated against 2 Grampositive bacterial (Streptococcus pyogenes and Micrococcus luteus); 2 Gram-negative bacterial (Shigella flexneri and Vibrio cholerae) and 2 fungal (Candida albicans and Aspergillus niger) isolates using aqueous and six organic ex...

Six pimarane-type diterpenes isolated from Viguiera arenaria Baker and two semi-synthetic derivatives were evaluated in vitro against a panel of representative microorganisms responsible for dental root canal infections. The microdilution method was used for the determination of the minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against Porphyromonas gingiva...

Necrotic enteritis in chicken is caused by the Clostridium perfringens, which have been found on almost chickensand for decades antimicrobial therapy was only strategy to control it. However misuse of antimicrobials linked many impacts like reduced susceptibility C. perfringens strains and cause cross-resistance agents. Thisworkdemonstrates that, uses herbal extracts with antibacterial effectsc...

Biofilm is a complex microbial community highly resistant to antimicrobials. The formation of biofilms in biotic and abiotic surfaces is associated with high rates of morbidity and mortality in hospitalized patients. New alternatives for controlling infections have been proposed focusing on the therapeutic properties of medicinal plants and their antimicrobial effects. In the present study the ...

This study assessed the occurrence of an enhancing inhibitory effect of the combined application of Origanum vulgare L. essential oil and lactic acid against Staphylococcus aureus by the determination of Fractional Inhibitory Concentration (FIC) index and cell viability in meat broth and meat model. Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) of the oil w...

LIM, S. H., DARAH, I. & JAIN, K. 2006. Antimicrobial activities of tannins extracted from Rhizophora apiculata barks. Tannin which was extracted from barks of Rhizophora apiculata was further separated into hydrolysable and condensed tannin. The results of the study revealed that only hydrolysable tannin showed significant antibacterial and antiyeast activities but not antifungal activity. The ...

This study was designed to investigate the antimicrobial activity of Cinnamomum iners standardized leave methanolic extract (CSLE), its fractions and isolated compounds. CSLE and fractions were subjected to disc diffusion, minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests using different Gram positive and Gram negative bacteria and yeast. Within the serie...

In this study antibacterial, antifungal and cytotoxic effects of some new 2,3-disubstituted 4(3H)-quinazolinone derivatives have been evaluated. The in vitro antibacterial and antifungal tests of new synthesized compounds were performed using MABA method against six strains of bacteria (three Grampositive and three Gram-negative) and three strains of fungi. Also Minimum Bactericidal Concentrati...
