OBJECTIVE To study the in-vitro antimicrobial activity of Cefpirome: A new fourth generation Cephalosporin in comparison with other agents against clinically significant Gram-negative and Gram-positive bacteria. SETTING A multi-center in-vitro study was conducted in 13 centers. MATERIALS AND METHODS Bacterial isolates--A total of 1300 isolates were collected from different clinical laborato...

Bacterial Pathogens Bacteria are the predominant organisms. In the late 1950’s/early 1960’s Gram+ve organisms were the commonest, particularly Staphylococcus aureus. The late 1960’s/early 1970’s were typified by Gram-ve of gastrointestinal tract origin, particularly Escherischia coli, Klebsiella spp and Pseudomonas spp. By the 1990’s Staphylococcus spp including coagulase negative organisms, St...

OBJECTIVES The aim of this study was to investigate relatedness and molecular mechanism(s) of ertapenem resistance in clinical isolates of Klebsiella spp. (n = 28) and Enterobacter spp. (n = 27) referred from multiple hospitals to the UK national reference laboratory. METHODS Investigations included genotyping by PFGE, resistance gene analysis by PCR and antimicrobial susceptibility testing w...

Bacterial sepsis is one of the major causes of morbidity and mortality among neonates. It is characterized as generalized bacterial infection indicated by positive blood culture in the first four weeks of life (Agarwal et al., 2001). The common causative agents for neonatal sepsis are Staphylococcus spp, Enterococci spp, E. coli, Klebsiella spp, Enterobacter spp, Pseudomonas aeruginosa and Acin...

CSOM is mostly caused by bacteria, but fungi and virus can also be a cause of CSOM. The aerobic microorganisms most frequently isolated in CSOM are Pseudomonas aeruginosa, Staphylococcus aureus, Gram-negative organisms such as Proteus spp., Klebsiella spp., and Escherichia spp., Citrobacter species, Haemophilus influenzae, and Moraxella catarrhalis (Gül et al., 2006; Verhoeff et al., 2006; de M...

background: urinary tract infection (uti) is considered as the most common bacterial infectious disease seen among the pediatric patients. the aim of this study was to investigate the prevalence and antimicrobial susceptibility of bacterial uropathogens isolated from the pediatric patients with urinary tract infections. methods: this descriptive study was conducted in children medial center, te...

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...

AIMS Aim of this study was to monitor the environment at the Transplant Unit-Hemato-Oncology Clinic, University Hospital Olomouc (Olomouc, Czech Republic) and identify risks for the patients. METHODS AND RESULTS Microorganisms were cultivated under standard aerobic conditions. Strains were biochemically identified using the BD Phoenix™ PID Panel (USA). Legionella pneumophila was identified by...

Background and Objectives: Nosocomial infections are one of the most important worldwide health and increased patients hospital stay, therapeutic problem and mortality rate. This study was designed to determine the frequency of microorganisms isolated from tracheal tube in patients admitted to ICU Shaheed Mostafa Khomeini Hospital Tehran, Iran, from 2001-2005. Patients and Methods: In this cros...

INTRODUCTION Multidrug resistance (MDR) and emergence of extended-spectrum β-lactamases (ESBLs) that mediate resistance to β-lactam drugs among Escherichia coli and other uropathogens have been reported worldwide. However, there is little information on the detection of ESBLs genes in E. coli from patients with urinary tract infections (UTIs) in the Arab countries using polymerase chain reactio...
