  Background: The spread of pathogenic microorganisms in food and beverage and their resistance to antibiotics have raised major concerns for public health. The aim of this study was to investigate the antimicrobial activity of various metal oxide nanoparticles (NPs) including zinc oxide (ZnO), magnesium oxide (MgO), and iron oxide (Fe2O3) NPs against Staphylococcus aureus (S. aureus) and Esch...

Recently, the effects of antimicrobial activity of silver nanoparticles was considered by researcher because of Bacterial resistance to antimicrobial agents in chemical.The aim of this study was to evaluate the antimicrobial activity of the gold nanoparticles on Escherichia coli. Gold nanoparticles are chemically synthesized. Standard strain of E. coli was cultured in a nutrient broth. Minimum ...

Gum of Butea monosperma is used to treat microbial and fungal infections in folk medicine. To validate this use, the in- vitro antimicrobial activity of petroleum ether and alcoholic extract of Butea monosperma gum was evaluated against various microbial strains such as Staphylococcus aureus, Bacillus subtilis, Bacillus cereus, Salmonella typhimurium , Pseudomonas aeuriogenosa, Esch...

Colicins are plasmid-encoded bacteriocins active against Escherichia coli and closely related species of Enterobacteriaceae. They promote microbial diversity and genetic diversity in E. coli populations. Colicin synthesis is characteristically repressed by the LexA protein, the key regulator of the SOS response. As colicins are released by cell lysis, generally two LexA dimers binding to two ov...

Objective(s): Bacteriophages are infectious replicating entities that are under consideration as antimicrobial bioagents to control bacterial infections. As an alternative or supplement to antibiotics, bacteriophages can be used to circumvent the resistance to existing antibiotics. The aim of this study was to assess the synergistic effect of a naturally isolated phage...

Comparative antimicrobial activity of four ointments, i. e. stellanin-PEG, levomecole, dioxydin 5% ointment and betadin was studied with the use of collection microbial strains and the most frequent pathogens of pyoinflammary processes in surgical patients. Clinical strains of gram positive and gram negative organisms were used as the test cultures. Stellanin-PEG 3% ointment showed high antimic...

With the emergence of multi-drug resistant bacteria the use of bacteriophages (phages) is gaining renewed interest as promising anti-microbial agents. The aim of this study was to isolate and characterize phages from human fecal samples. Three new coliphages, ɸAPCEc01, ɸAPCEc02 and ɸAPCEc03, were isolated. Their phenotypic and genomic characteristics, and lytic activity against biofilm, and in ...

Background and Objective: This study aimed to determine the antibacterial activity of either zinc oxide or copper oxide nanoparticles alone or combined against Gram-positive and Gram-negative bacteria. Materials and Methods: In this experimental study Escherichia coli (E. coli ATCC 25922), Staphylococcus aureus (S.aureus ATCC 25923), Pesudomonas aueroginosa (P. aueroginosa ATCC 27853) and Staph...
