In the present study, anaerobic clinical isolates of Bacteroides fragilis, Escherichia coli, Staphylococcus aureus and Yersinia enterocolitica were obtained from different clinical specimens and were subjected to molecular typing to detect the gene encoding metronidazole resistance in these isolates. Subsequently, antibacterial activity of drugs was tested against the selected clinical isolates...

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...

To make use of nano-sized particles for biomedical applications such nanomedicines for different diseases, it is important to study how nanoparticles behave when they interact with microorganisms. In the present study, we investigated the antibacterial performance of chromium oxide nanoparticles (Cr3O4 NPs) against two gram negative bacterial strains, Escherichia coli, and Pseudomonas aeruginos...

Aureobasidium pullulans is ubiquitous, polymorphic and black fungus producing a variety of important metabolites including enzymes, polysaccharides and single cell protein. It is considered as a probable source for antagonistic activity against a number of phytopathogenic fungi and possible biocontrol agent of post harvest diseases. The present work aims at the antibacterial compounds produced ...

     Phytochemical Screening, Antibacterial and Cytotoxic Activities of Petroselinum crispum Leaves Grown in Oman.Petroselinum crispum belongs to the Apiaceae family, is a well-known spice and vegetable. The essential oil obtained from the fruit has also strong action on the central nervous system. Present study is designed to evaluate the phytochemical screening, antibacterial and cytotoxic ac...

Ethanolic extracts of eight medicinal plants commonly used in folk medicine were tested for their antibacterial activity against four Gram positive strains (Bacillus subtilis, Staphylococcus aureus, Staphylococcus epidermidis and, Streptococcus pneumoniae) and six Gram negative strains (Escherichia coli, Proteus vulgaris, Proteus mirabilis. Salmonella typhi para A, Salmonella typhi para B and S...

Crotalaria juncea Linn. (leguminoceae), is used as medicine in the traditional system of Indian medicine for the treatment of anaemia, impetigo, menorrhagia, psoriasis etc. The objective of this study was to evaluate antibacterial activity of the seed and flower parts of C. juncea. The ethanol extract of flowers part (CJFEE) and seeds part (CJSEE) were evaluated for the antibacterial activity b...

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...

BACKGROUND Infectious diseases are the most common causes of morbidity and mortality in developing countries. Wound and wound infections are also major health problem. Nowadays, medicinal plants play a major role in treatment of infectious diseases and wound healing and they are easily available and more affordable as compared to synthetic compounds. The aim of this study is therefore, to inves...

Background: This study aimed at investigation of the chemical composition, antimicrobial activity, and antioxidant properties of clove, cumin, origanum, and anise Essential Oils (EOs). Methods: Chemical compositions of the EOs were identified using Gas Chromatography/Mass Spectrometry (GC/MS). The antibacterial activities of EOs against four important food-borne bacteria were assessed by disc ...
