BACKGROUND Susceptibility pattern of organisms causing urinary tract infection (UTI) in neonate would potentially improve the clinical management by enabling clinicians to choose most reasonable first line empirical antibiotics. This study aimed to this end by studying isolated organisms from neonates with UTI in an inpatient setting. METHODS Current retrospective study has recruited all case...

BACKGROUND Shigella sonnei is considered as a major cause of diarrheal disease in both developing and developed countries. Iran is one of the endemic areas of shigellosis. The present study was undertaken to investigate the antibiotic susceptibility and genetic relatedness of S. sonnei strains isolated from pediatric patients in Tehran, Iran. METHODS The study included all S. sonnei strains i...

BACKGROUND & OBJECTIVE Pseudomonas aeruginosa is a common cause of nosocomial infections and exhibits innate resistance to a wide range of antibiotics. This study was undertaken to determine the resistance patterns of P. aeruginosa isolates recovered from patients at two hospitals in Tehran, to investigate the presence of plasmids and to genetically characterize them by pulsed field gel electro...

E. coli is the main agent of uncomplicated urinary tract infections (UTIs) and accounts for more than 85% of recurrent cystitis and at least 35% of recurrent pyelonephritis. Despite the widespread availability of antibiotics, UTIs remain the most common bacterial infection in the human population. It is currently advised that the clinical administration of antibiotics against the pathogenic bac...

Urinary tract infection (UTI) is 1 of the most common bacterial diseases in children with a considerable resistance to antimicrobials. This 5 years prospective study was carried out to determine the frequency of isolation and antimicrobial resistance patterns of uropathogens among children subjected to urine culture at Tabriz Children Educational-Health Care Center, in the northwest of Iran. Or...

The plasmid pBWH77, originally found in an isolate of Klebsiella pneumoniae, harbors a new antibiotic resistance operon containing two resistance genes transcribed from an IS26-hybrid promoter, as shown by nucleotide sequencing, mRNA mapping, and the effect of inserting a transcription terminator within the promoter-proximal gene. The nucleotide sequence of this region revealed that the operon ...

This study was carried out to determine the antimicrobial susceptibility patterns of 584 Shigella flexneri isolated from diarrheal patients admitted in hospitals in Azad Kashmir Pakistan and to evaluate their changing trends against twenty antibiotics. The isolates showed highest resistance against penicillin followed by carbenicillin, ampicillin, tetracycline, erythromycin, ceftizoxime, kanamy...

Background/Aims. Spontaneous bacterial peritonitis (SBP) is one of the leading causes of morbidity and mortality in patients with cirrhosis. This study aims to determine the microbial agents of SBP and the pattern of antibiotic resistance, in a large number of ascitic samples. Methodology. In a cross-sectional, single center, hospital based study, 1981 consecutive ascitic fluid samples were rec...

INTRODUCTION Antibiotic resistant mutants producing extended-spectrum beta-lactamase (ESBL) have emerged among Escherichia coli and Klebsiella pneumoniae. This study was done to determine the frequency of ESBL-producing E coli and K pneumoniae species isolated from urine samples of our patients. MATERIALS AND METHODS A study was conducted on 164 urine isolates (124 E coli and 40 K pneumoniae)...
