colibacillosis caused by e.coli is one of the most common illnesses in commercial chickens and induce high financial losses in the poultry industry due to morbidity, mortality and antibiotic expenses because of overuses. e.coli can mostly cause disease as a secondary or opportunistic pathogen, while certain strains with specific virulence factors even as primary pathogen can cause colibacillosi...

objective bacterial adhesion is governed by specific and nonspecific interactions such as hydrophobicity. hydrophobic interactions play a role in the adherence of microorganisms to a wide variety of surfaces and facilitate biofilm formation due to bacterial adhesion. in this article the relation between cell surface hydrophobicity and antibiotic resistance was studied. materials and methods we ...

conclusions tetracycline resistance is widespread among uropathogenic e. coli isolates from human infections. moreover, the distribution of tetracycline resistance determinants among the studied e. coli was very similar to the findings of the international sourced gallery of clinical e. coli strains. background uropathogenic escherichia coli is one of the most prevalent infectious agents in hum...

background the rapid emergence of antibiotic resistance, especially broad-spectrum antibiotics, resulted in the avid use of new potent antibiotics. ceftriaxone and ceftazidime, two third-generation cephalosporin, are usually used to manage complicated and uncomplicated infections. the use of cefepime in resistant infections is increasing gradually, which put this potent antibiotic at risk of re...

conclusions the results of this study show that the rate of p. aeruginosa-caused burn wound infections was very high, and many of the isolates were resistant to three or more classes of antimicrobials. such extensive resistance to antimicrobial classes is important because few treatment options remain for patients with burn wound infections. blaimp-producing p. aeruginosa isolates are a rising ...

background pseudomonas aeruginosa is a leading cause of infections especially in patients with weakened immune systems. this pathogen is intrinsically resistant to many antibacterial agents. objectives the aim of this study was to survey the antibiotic resistance pattern and frequency of bla oxa10 gene in carbapenemase producing p. aeruginosa isolated from patients in isfahan hospitals. materia...

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 determined...

a total of 385 urine specimens from suspected urinary tract infections were subjected to bacteriological analysis and susceptibility testing at a major university hospital laboratory in tehran. a battery of eight beta-iactam antibiotics, commonly prescribed in iran, and three third-generation cephalosporins (ceftazidime, ceftriaxone and ceftizoxime) that are usually reserved for limited use in ...

Objective: This review discusses the impact of antibiotic resistance in the intensive care unit (ICU), including the prevalence, morbidity, antibiotic resistance patterns and factors perpetuating antibiotic resistance. In addition, this describes the clinical significance of antibiotic resistance, the mechanisms of resistance, and suggests strategies to combat resistance. Summary: Antibiotic re...

objective: aminoglycosides are highly potent, broad-spectrum antibiotics with many desirable properties for the treatment of life-threatening infections. escherichia coli (e. coli) is the most common cause of urinary tract infection (uti). antibiotic resistance has recently become prevalent. enzymatic inactivation of aminoglycosides by aminoglycoside-modifying enzymes is the main mechanism of r...
