This study was performed to isolate actinomycete colonies having antibacterial activity from soil samples collected from different places around Rajshahi, Bangladesh. Thirty actinomycete colonies were isolated in pure culture from five soil samples using Starch-casein-nitrate-agar medium. The isolates were grouped in five color series based on their aerial mycelia color and screened for their a...

5-Thiourea and 5-dithiocarbamate oxazolidinones were synthesized as a continuation of research on 5-thiocarbonyl oxazolidinone antibacterial agents considering the hydrophobic parameters of the molecule. The structure-activity relationship (SAR) study revealed that the antibacterial activity on 5-thiocarbonyl oxazolidinones was significantly affected by the lipophilicity, especially the calcula...

The present study was carried out to evaluate the antibacterial activities ofethanolicand aqueous extracts of Kigelia africana (Bignoniaceae) and Carica papaya (Caricaceae) against multi drug resistant Pseudomonas aeruginosa UTI causing pathogen. The bacterial sp was isolated from urine sample of UTI infected patient and identified with the help of colony characterization, gram staining and bio...

BACKGROUND Bauhinia kockiana originates from Peninsular Malaysia and it is grown as a garden ornamental plant. Our previous study reported that this plant exhibited fairly strong antioxidant and antimicrobial activities. This paper focused on the assessment of the antibacterial activity of B. kockiana towards methicillin-resistance Staphylococcus aureus (MRSA), to purify and to identify the ant...

UNLABELLED Dental caries is still a major oral health problem in most industrialized countries. The development of dental caries primarily involves Lactobacilli spp. and Streptococcus mutans. Although antibacterial ingredients are used against oral bacteria to reduce dental caries, some reports that show partial antibacterial ingredients could result in side effects. OBJECTIVES The main objec...

The authors studied the effect of storage period and heat on the physical and chemical properties of honey and proceeded to study the antibacterial effect of honey on Escherichia coli and Salmonella typhimurium. In samples of honey (Egyptian clover honey) that were heat-treated and stored over a long period of time, water content decreased, hydroxymethyl furfural (HMF) was produced and increase...

Origanum vulgar belongs to the plant family of Asteraceae , native to temperate Asia, but naturalized in many countries including scattered parts of North America (11, 12). It is an annual short-day plant. Its stem is erect brownish or violet brown. The aim of this study was to overview its Antioxidant, anticancer, antimicrobial effect. This review article was carried out by searching studies i...

BACKGROUND Herbal medicines have long been used for various ailments in various societies and natural bioactive compounds are gaining more and more importance due to various factors. In this context, three plant species i.e., Eryngium caeruleum, Notholirion thomsonianum and Allium consanguineum have been aimed for the scientific verification of their purported traditional uses against various i...

When pathogenic bacteria breach the epithelial lining at mucosal surfaces, rapidly available innate immune mechanisms are critical to halt the infection. In the present study, we characterized the production of antibacterial polypeptides released by epithelial cells. IFN-γ, but neither TNF nor IL-1β alone, induced release of antibacterial activity to a cell culture medium, causing a lytic appea...

Objective: The aim of this study was to investigate the antibacterial activity of Genistein and Quercetin against pathogens of the urinary tract infection (UTI). Methods: An in vitro study was carried out using the following bacterial strains involved in UTI diseases using well diffusion (WD) testing: Escherichia coli (ATCC 25922) and 10 strains were compiled from Aleppo Hospital. It was from w...
