Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment infections. Nanomedicines, such as chitosan (CS) can carry multiple drugs and improve therapeutic effects antibiotics. Objectives: This study aimed at synthesis characterization ciprofloxacin-loaded nanoparticles for eradication P. aeroginosa biofilm. Methods: Cipro-CS microparticles were prepared by ionic...

Saprolegnia is one of? the? ?most important agents decreasing the eggs survival rate in sturgeon hatcheries. There are some chemical substances for controlling the fungal infection of eggs. In this study, an attempt was made to introduce a ?germ negative bacterium, Pseudomonas aeroginosa (PTCC1430)(Persian Type Culture Collection) as a biocontrol??ling agent of? ?water mold. Saprolegnia was...

The objective of the present research was to develop vacuum packaging incorporated with Rosmarinus officinalis L. essential oil treatment of fresh chicken breast meat. For this purpose, fresh chicken’s meat breast samples were divided into three groups. First group was kept as a control group with air packaging, others one was with vacuum packaging of samples and last one group was treated with...

Background and Objectives: Nosocomial infections are one of the most important worldwide health and increased patients hospital stay, therapeutic problem and mortality rate. This study was designed to determine the frequency of microorganisms isolated from tracheal tube in patients admitted to ICU Shaheed Mostafa Khomeini Hospital Tehran, Iran, from 2001-2005. Patients and Methods: In this cros...

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...

Production of antimicrobial compounds seems to be a general phenomenon for most bacteria. The prevalence of antimicrobial resistance among key microbial pathogens is increasing at an alarming rate worldwide. Current solutions involve development of a more rationale approach to antibiotic use and discover of new antimicrobials. Bacillus species produce a large number of biological compounds acti...

Medicinal plants are being used as traditional medicines to cure several infectious and non-infectious diseases because of their products are safe in contrast to the synthetic medicines that are considered as unsafe to human including other animals and environment. We selected Solanum nigrum L. (Makoi) which belongs to family Solanaceae to evaluate antimicrobial activities against six pathogeni...
