background and objectives: group b streptococci (gbs) is a major cause of neonatal and maternal infections. the aim of this study was to determine the serotype distribution and antibiotic resistance profile of gbs strains isolated from pregnant women in ardabil. materials and methods: antibiotic resistance of 56 gbs isolates was investigated using e-test strips and disk-diffusion method. seroty...

the present study aimed to evaluate the antibiotic resistance pattern of escherichia coli strains isolatedfrom animals to ascertain the levels of antibiotic resistance pervasiveness. a total of 28 e. coli strains wereisolated from faecal samples and the antibiotic resistance pattern of e. coli strains was determined by meansof disc diffusion assay. the resistance pattern determined for all stra...

streptococcuscus beta hemolytic group a is the most important pathogen causing which may lead to purulent and non purulent angina. rheumatic fever is the most important complication that is the cause of 30% to 40% of cardiac disease and disablement. this study was performed to evaluate prevalence of streptococcuscus beta hemolytic group a and estimate role of clinical findings in children with ...

The frequency of mutants resistant to the antibiotic rifampicin has been shown to increase in aging (starved), compared to young colonies of Escherichia coli. These increases in resistance frequency occur in the absence of any antibiotic exposure, and similar increases have also been observed in response to additional growth limiting conditions. Understanding the causes of such increases in the...

background pseudomonas aeruginosa is an opportunistic pathogen mostly affecting hospitalized and immunodeficient patients. considering the extent of attention paid to the issue of antibiotic resistance and the origin of such resistance and the growing number of treatment failures in patients with burn injury, it seems that investigating the degree of ampc gene expression could be beneficial for...

Antibiotic abuse can lead to antibiotic resistance, which is a severe problem in China. The purpose of this study is to evaluate the short-term effects of antimicrobial stewardship strategies, including formulary restriction, preauthorization, perioperative quinolone restriction, and control of total antibiotic consumption in the ICU at a tertiary hospital in China. After implementation of anti...

staphylococcus aureus causes a wide variety of infections worldwide. methicillin-resistant s. aureus is one of most common causes of nosocomial and community acquired infections. the fluoroquinolones are an important class of antibiotics that used to treat infections caused by s. aureus. today, a significant increase in the rate of ciprofloxacin resistance in methicillin-resistant s. aureus str...

BACKGROUND We examined how prolonged antibiotic treatment affected the resistance and mutation frequency of human microflora isolated from intestine (Escherichia coli, enterococci spp.), pharynx (alpha-streptococci) and nostril (coagulase-negative staphylococci, CoNS). METHODS Samples were collected from patients at the Center of Cystic Fibrosis (n=18) and the haematology ward (n=18) of the U...

background and objectives : salmonella is one of the leading causes of food-borne diseases. increasing occurrence of antimicrobial resistance, especially multidrug-resistance, in salmonella serovars is a major public health problem worldwide. this study was carried out to detect class i integrons and antibiotic resistance profiles in clinical isolates of salmonella serovars collected from seven...
