Introduction: Ozon is increasingly used for swimming pools disinfecting in Iran. The scope of this cross-sectional study was to the determine ozonation eficiency and influence of pool depth and swimmers gender on the six microbial quality indices. Methods: In this investigation, total Coliform, E.Coli, Heterotrophic bacteria, Streptococcus Feacalis, Staphylococcus Aureus and Pseudomonas Aero...
Zinc sulfide (ZnS) & zinc oxide (ZnO) nanoparticles was evaluated for their antimicrobial activity against four pathogenic strains. ZnS&ZnO nanoparticles were synthesized by simple aqueous chemical reaction in an aqueous solution. The main advantage of these nanoparticles (size of 10-30 nm) was that simply could be prepared by using cheap precursors in a cost effective and high throughput manne...
most of poly aromatic hydrocarbons are stable in marine environment and don’t degrade easily. if they accede to the aquatic animals bodies, they will accumulate in their fat tissues. the toxic effects of these compounds are consisting of carcinogenic, mutagenic and germinal tribulation. hence present study was done with purpose of isolation and identification of naphthalene degrading bacteria a...
چکیده بیماری بوته میری(damping off) یکی از مهم ترین بیماری های گیاه طالبی می باشد که خسارت قابل توجهی به این محصول وارد می نماید. یکی از مهم ترین عوامل ایجاد کننده ی این بیماری قارچ phytophthora drechsleri است. در این بررسی اثر همستیزی سودوموناس های فلورسنت جدا شده از ریزوسفر طالبی، در کنترل زیستی این بیماری مطالعه گردید. بعد از جداسازی بیمارگر از خاک و طوقه ی بوته های بیمار، به وسیله ی آزمون ...
Background and purpose: Chitin, which entails the most abundant biopolymer in nature after cellulose, having found numerous applications in food processing, cosmetics, agriculture, medical and environment. Natural sources of this polymer are component of exoskeletons of crustaceans and insects as well as cell walls from some bacteria and fungi. Chitosan is a partially deacetylated polymer of ...
Echinoderms are independent and quite special branch of world animals. Sea cucumbers are among the strangest members of echinoderm class regarding their structure and physiology. These fauna have been tested with regard to anti-bacterial, anti-fungal, anti-coagulants, anti-virus, cytotoxic, hemolytic and anti-HIV features. In this study, the antibacterial activity of Holothuria leucospilota...
The aim of this study was to evaluate the antibacterial activity of the water extracts of three species of Salvia (S. perspolitana, S. palaestina, S. bracteata) on Staphylococcus aureus, Escherichia coli and Pseudomonas aeroginosa. The antibacterial activity of water extracts of the studied species on the bacterial strains was examined using well diffusion method and minimum inhibitory concentr...
Background: Pseudomonas aeruginosa biofilm is one of the problems in antibiotic treatment of infections. Nanomedicines such as chitosan can carry multiple drugs and improve the therapeutic effects of antibiotics. Objectives: The study aimed to synthesis and characterization of ciprofloxacin loaded chitosan nanoparticle for eradication biofilm of P. aeroginosa. Methods: Cipro-CS microparticles...
Abstract Background and Objective: Bacterial infectioins in particular meningitis, pneumonia and septicemia are still some of the most causes of mortalities in children.The aim of present study was to identify the most common bacterial agents causing infectionis in children under 14 and detection of antibiotic resistance paterns. Material and Methods: During two years,1897samples were...
