Objective: Infections are increasing caused by antibiotic-resistant Pseudomonas aeruginosa day by day. For this reason, many researchers have tried to find new compounds as alternative antibiotics. The purpose of this study was to evaluate the effect of yarrow extract, green tea and Ajowan  on Pseudomonas aeruginosa. Methods: Extraction  of Achillea, green tea and Ajowan was done with rotary. F...

Background & Aim: The aim of this study was to investigate the antimicrobial effects of Zataria multiflora against some Acinetobacter baumannii strains isolated from clinical samples. Experimental: Twelve strains of Acinetobacter baumannii were isolated from referred patients in Zabol hospital. Essential oil of Zataria multiflora...

Abstract Introduction: Achievement of new drugs with minimal side effects is a important goal in the cancer treatment due to irreversible side effects of conventional drugs. Tricalcium phosphates as natural bone components have unique characteristics including excellent biocompatibility, high biosorption and superior bioactivity. This research aimed at investigating the inhibitory effect of tr...

The minimal inhibitory concentrations of 30 antibiotics were determined by the agar dilution method for 17 penicillinase-positive and 50 penicillinase-negative strains of Neisseria gonorrhoeae. The latter included 42 strains that were penicillin susceptible (pen S) (minimal inhibitory concentration, <0.125 mug/ml) and 8 strains with intermediate resistance to penicillin (pen I; minimal inhibito...

We have reevaluated the antibiotic susceptibilities of group A beta-hemolytic streptococci in view of recent reports of a high prevalence of erythromycin resistance in Japan and of an increase in penicillin treatment failures in the United States. A total of 474 isolates recovered during a 2- to 3-month period in 1980 were tested. All were susceptible by microtiter broth dilution to a penicilli...

This work described a simple and efficient method for the synthesis of 1-azabicyclo[3.1.0]hexane-3-ene derivatives. arylidenmalononitriles and hydroxylamine hydrochloride in the presence of NaOH, under microwave irradiation and solvent-free conditions produced the titled compounds in good to excellent yields. Using of simple chemicals, short reaction times, and solvent-free conditions, high yie...

objectives:biofilms are communities of bacteria attached to surfaces through an external polymeric substances matrix. in the meantime, acinetobacterbaumannii is the predominant species related to nosocomial infections. in the present study, the effect of silver nanoparticles alone and in combination with biocides and imipenem against planktonic and biofilms of a. baumannii was assessed.  materi...
