conclusions preliminary results indicate that the native iranian actinobacteria could be considered a suitable option for screening of the new antibacterial compounds. molecular research and antibacterial compound extraction against the aforementioned pathogenic strains are also being conducted. results based on the morphological characterization, 35 isolated cases belonged to actinomycetes and...

Background: Innovative bioactive films incorporated with antimicrobial agents have been recently developed for food preservation. The aim of this study was to evaluate antibacterial activity of Polylactic Acid (PLA) films incorporated with Ziziphora clinopodioides Essential Oil (ZEO) and Ethanolic Propolis Extract (EPE) against some common food-borne pathogens. Methods: The volatile chemical...

The antibacterial properties of a polymeric phosphonium salt were studied to determine its suitability as an additive to develop an antibacterial dental resin. The phosphonium salt monomer studied was tri-n-butyl(4-vinylbenzyl)phosphonium chloride (VP), and acrylic acid (AC) and methacryloyloxyethyl trimethyl ammonium chloride (MA) were used as controls. The antibacterial activity of these mono...

background: mentha piperita l. essential oils have different antibacterial activity. in the present study, we investigated the effect of γ–irradiation on the antibacterial activities of mentha piperita l. essential oils in vitro and in vivo systems. materials and methods: the aerial parts of peppermint were irradiated in a cobalt60 source with 0, 10 and 25 kgy absorbed doses. then, the plants w...

BACKGROUND hGlyrichin is a novel human antimicrobial peptide rich in glycine. The previous study of known human antimicrobial peptides indicated that in an eligible range, the greater corresponding antibacterial activity was consisted with the shorter peptide sequence. FINDINGS Two peptides named pCM19 and pCM12 were synthesized and the antibacterial activity assay results showed that these p...

Three extracts of Pulicaria dysenterica were examined for antibacterial activity using the agar disk-diffusion method against six bacterial strains. Some of these extracts were found to be active against some bacterial strains. The methanolic extract exhibited a superior level of antibacterial activity. All of the extracts were active against Vibrio chlorea.

The antibacterial activity of honey has been known since the 19th century. Recently, the potent activity of honey against antibiotic-resistant bacteria has further increased the interest for application of honey, but incomplete knowledge of the antibacterial activity is a major obstacle for clinical applicability. The high sugar concentration, hydrogen peroxide, and the low pH are well-known an...

1. A key component of parental care involves defending resources destined for offspring from a diverse array of potential interspecific competitors, such as social parasites, fungi and bacteria. 2. Just as with other aspects of parental care, such as offspring provisioning or brood defence, sexual conflict between parents may arise over how to share the costs of this form of care. There has bee...

We provide epidemiological evidence that shell disease, a very common problem of crustaceans in polluted environments, coincides with low serum antibacterial activity. In commercially important blue crabs Callinectes sapidus from the Albemarle-Pamlico Estuary, North Carolina, USA, we identified potent antibacterial activity which was active against most of the bacteria inhabiting the shell of b...

Antibacterial activity of Fe3O4 nanoparticles was investigated in three microorganisms including P. aeruginosa, E. Coli and Staphylococcus aureus. Fe3O4 nanoparticles were synthesized by chemical precipitation method (20 nm). The Fe3O4 nanoparticles antibacterial effect against Pseudomonas aeruginosa, Escherichia coli and Staphylococcus aureus were studied by the culture method. First of all, e...
