Ten healthy volunteers received 1 g of BRL-36650, a new formamido-penicillin derivative, given by intravenous infusion over 15 min. Levels in serum were measured microbiologically 30, 60, and 120 min after the start of the 15-min infusion and were (mean +/- standard deviation) 102.7 +/- 28.4, 59.7 +/- 11.5, and 9.6 +/- 1.9 mg/liter, respectively. A total of 10 strains each of Escherichia coli, ...

Cronobacter spp. (Enterobacter sakazakii) is an opportunistic bacterial pathogen capable of causing disease and even fatalities in newborn infants within the first weeks of life if consumed as part of the diet. Premature and immunocompromised newborn infants are at particular risk. The microorganism has been isolated from a variety of foods including contaminated infant milk formula powder and ...

INTRODUCTION Knowledge of the microbiology of surgical infections after abdominal surgery can be of use when prescribing effective empirical antibiotic treatments. METHOD Analysis of surgical infections after abdominal surgery in patients enrolled in the Prevalence of Infections in Spanish Hospitals (EPINE) corresponding to the years 1999-2006. RESULTS During the period of the study, 2,280 ...

The in-vitro activity of colistin sulphomethate sodium was compared with that of other commonly used antimicrobial agents against 377 recent clinical isolates of Gram-negative bacteria (including 94 strains of Pseudomonas aeruginosa from patients with cystic fibrosis) and 16 organisms with defined resistance patterns. Colistin was active against most strains of P. aeruginosa (MIC90 4 mg/L), Shi...

OBJECTIVE To evaluate the trends of ciprofloxacin resistance pattern in commonly isolated gram-negative bacteria over time in a Saudi Arabian teaching hospital. METHODS A retrospective analysis was carried out for ciprofloxacin resistance patterns of 10089 isolates of gram-negative bacteria isolated from various clinical specimens submitted to microbiology laboratories at King Fahd Hospital o...

The AutoMicrobic system (AMS) is capable of identifying most Enterobacteriaceae within 8 h and many glucose-nonfermenting, gram-negative bacilli after 13 h of incubation. Early preliminary results can be readily obtained from the computer as the tests incubate. Data with 1,023 bacterial isolates were reviewed to determine the relative accuracy of 4-, 6-, 8-, 10-, and 13-h identifications. All A...

The in vitro activity of R-3746, an iminomethoxy aminothiazolyl cephalosporin with a CH2OCH3 moiety at position 3, was compared with those of other antibiotics. R-3746 inhibited the majority of hemolytic streptococci (groups A, B, C, F, and G) and Streptococcus pneumoniae at less than 0.06 micrograms/ml, which was comparable to the activity of amoxicillin, 2- to 8-fold more active than cefixime...

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...

microbial biofilms has remained a major complication of tracheal intubation in patients requiring ventilator equipment. the aim of this study was to characterize bacterial and fungal biofilms in endotracheal tubes from intensive care unit (icu) patients in ahwaz, iran. in this cross-sectional descriptive study, patients admitted to icu that required mechanical ventilation for at least 24 hours ...

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...
