abstract: chitosan is a natural antimicrobial which is derived from non-toxic animal resources. this study investigated and compared the antimicrobial characteristics of chitosan which was extracted from shell of artemia cyst in the lake of urmia with the same commercial chitosan feature to that of crab shell from a.p.t firm in vietnam. the experiment was carried by means of two fulded method t...

Antibacterial activity of cold water and ethanolic crude extracts of leaves of Strophanthus wightianus Wall. ex Wight was evaluated against Gram negative bacteria(Escherichia coli, Pseudomonas fluorescens, Klebsiella pneumoniae and Enterobacter aerogenes) and Gram positive bacteria (Staphylococcus aureus, Methicillin resistant Staphylococcus aureus, Streptococcus mutans and Bacillus subtilis). ...

Background: Treatment of chronic sinusitis is complicated due to increase of antibiotic-resistant bacteria. The aim of this study was to determine the multidrug resistance (MDR) pattern of the bacteria causing chronic sinusitis in north of Iran. Methods: This cross-sectional study was carried out on patients with chronic sinusitis. Bacterial susceptibility to antimicrobial agents was determi...

background: many efforts have been done to find effective agents against resistant pathogens. cuminum cyminum l. (cumin) is an aromatic plant within the apiaceae family. it has a variety of purposes and demonstrates antimicrobial and antioxidant properties. this study evaluated the activity of c. cyminum extract and essential oil against bacterial isolates which cause urinary tract infection, i...

E-0702 is an antipseudomonal cephalosporin derivative which has a broad spectrum of antibacterial activity against clinical isolates of gram-positive and gram-negative bacteria. Its in vitro antibacterial activities were less than those of cefoperazone and cefotaxime against Staphylococcus aureus and Staphylococcus epidermidis, but were significantly high against gram-negative bacteria includin...

We have evaluated serological tests for the diagnosis of Staphylococcus aureus osteomyelitis. Antiteichoic acid antibodies were elevated in 17 of 23 patients with acute and 16 of 46 with chronic S. aureus osteomyelitis but in none of 33 patients infected with other gram-positive or gram-negative bacteria. Immunoglobulin G antibodies to S. aureus were elevated in 12 of 23 patients with acute and...

Aim and Objective: To determine the bacterial spectrum in diabetic foot lesions and analyze the antibiotic susceptibility pattern of the isolated bacteria. Methods and Methodology: Tissue samples/discharge/pus/ were cultured from 202 patients admitted for the treatment of diabetic foot infections. Specimens were tested by gram stain, culture and antibiotic sensitivity. Results: A total of 202 s...

abstract background: the invasion of microorganisms into the bloodstream and spread to different parts of body can cause disruption the functions of vital organs and even death. the proper and prompt treatment is essential and can significantly reduce morbidity and mortality rates. this study aimed to determine the frequency and the antimicrobial susceptibility of bacteria isolated from blood c...

biotics having low toxicity and high activities against both Gram-positive bacteria including methicillin-resistant Staphylococcus aureus (MRSA) and Gram-negative bacteria including Pseudomonas aeruginosa (P. aeruginosa), which are the main bacteria causing nosocomial infections, are now urgently required. Recently, we introduced cefoselis (CFSL)4'5), which shows potent broadspectrum activity a...
