Objective(s): Antibacterial materials are so significant in the textile industry, water disinfection, medicine, and food packaging. Unfortunately, organic compounds for sterilization show toxicity to the human body; therefore, the interest in inorganic disinfectants such as metal oxide nanoparticles (NPs) is increasing. Materials and Methods: Nickel and nickel hydroxide nanoparticles (NiNPs ...

Endophytic fungi were isolated from healthy leaves of Indigofera suffruticosa Miller, a medicinal plant found in Brazil which is used in folk medicine to treat various diseases. Among 65 endophytic fungi isolated, 18 fungi showed activity against at least one tested microorganism in preliminary screening, and the best results were obtained with Nigrospora sphaerica (URM-6060) and Pestalotiopsis...

BACKGROUND Blechnum orientale Linn. (Blechnaceae), a fern, is traditionally used in the treatment of various ailments, such as skin diseases, stomach pain, urinary bladder complaints, and also as a female contraceptive. Previously, we reported a strong radical scavenging activity, antibacterial activity and cytotoxicity against HT29 colon cancer cells by aqueous extract of B. orientale. OBJEC...

Background: Alkaloids are a group of nitrogen- containing natural compounds derived from a variety of sources including bacteria, fungi, marine organisms and plants. Materials and methods: Fruits, stem or leaves were collected from the Zagros highlands around Azna or Khoramabad city, dried and powdered before being extracted in a soxhalet apparatus. The extract was filtered and concentrated u...

The antidermatophytic activity of interpolar methanolic and low polar petroleum ether soxhlet extracts of Sterculia foetida seed was evaluated by agar well diffusion method, The maximum activity was observed in interpolar methanolic extract against C .albicans followed by E. coli, B. Subtilis, P. aeruginosa, S. aureus, T. rubrum, M.gypseum, T.mentagrophytes and T.tonsurans. When compared to low...

Ethanolic and aqueous (hot and cold) extracts of the fruit pulp, stem bark and leaves of Tamarindus indica were evaluated for antibacterial activity, in vitro, against 13 Gram negative and 5 Gram positive bacterial strains using agar well diffusion and macro broth dilution techniques, simultaneously. The fruit pulp extracts exhibited a wide spectrum of activity; the cold water extract against 9...

Purpose: To determine the anti-Streptococcus pyogenes activity of the chloroform extract of Boesenbergia pandurata (Roxb.) Schltr. (Zingiberaceae) and investigate its possible antibacterial mechanisms of action. Methods: Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) values were investigated against 47 clinical isolates of S. pyogenes. Time-kill study was pe...

vibrio cholerae is a human pathogen that causes mild to severe diarrheal illnesses and has major public health significance. the aim of this study was to investigate the effects of antimicrobial activity of the gold nanoparticles on vibrio cholera. gold and silver nanoparticles are chemically synthesized. standard strain of vibrio cholerawas cultured in a nutrient broth. minimum inhibitory conc...
