BACKGROUND Neonatal bilateral endogenous endophthalmitis is rare and often results in devastating visual outcome. FINDINGS An 18-day-old neonate presented with whitening of the cornea in the left eye. The child was examined under anesthesia, and a diagnosis of bilateral endogenous endophthalmitis was made. Vitreous biopsy from the left eye showed no growth. Blood samples showed growth of Stap...

MICs of eight beta-lactams (piperacillin, piperacillin-tazobactam, ticarcillin, ticarcillin-clavulanate, ampicillin, ampicillin-sulbactam, ceftazidime, and ceftriaxone) were determined by agar dilution against 64 penicillin-susceptible, 70 intermediately penicillin-resistant, and 66 fully penicillin-resistant pneumococci. The MICs of piperacillin with and without tazobactam for 90% of the susce...

Background & Aims: Utility of antibiotics, such as third and fourth generation of cephalosporins and carbapenems, and resistance to these antibiotics in hospital acquired infections are increased. There are scientific data that support the application of Tazocin (piperacillin-tazobactam) as an empirical treatment of moderate to severe bacterial infections. In our area there is not much informat...

We examined the drug susceptibility pattern of Gram-negative bacilli to seven new beta-lactams. A total of 277 non-duplicate gramnegative bacilli strains belonging to the Enterobacteriaceae family, Pseudomonas and Acinetobacter species, isolated from various clinical samples were tested for susceptibility to imipenem, piperacillin/tazobactam, cefoperazone/sulbactam, ticarcillin/clavulanate, cef...

OBJECTIVES Appropriate antibiotic exposure at the site of infection is important for clinically effective therapy. This study compared the epithelial lining fluid (ELF) penetration of ceftolozane/tazobactam, which has potent in vitro activity against many Gram-negative pathogens causing nosocomial pneumonia, with that of piperacillin/tazobactam in healthy adult volunteers. METHODS In this Pha...

BACKGROUND Ertapenem, a new carbapenem with a favorable pharmacokinetic profile, has been approved for the treatment of complicated intra-abdominal Infections (cIAIs), acute pelvic infections (APIs) and complicated skin and skin-structure infections (cSSSIs). The aim of this study is to compare the efficacy and safety of ertapenem with piperacillin/tazobactam, which has been reported to possess...

Respiratory tract infections cause 90% of premature mortality in patients with cystic fibrosis (CF). Treatment of Pseudomonas aeruginosa infection is often very problematic. Piperacillin-tazobactam has good activity against P. aeruginosa, but its pharmacokinetics (PK) in CF patients has not been compared to the PK in healthy volunteers in a controlled clinical study. Therefore, we compared the ...

BACKGROUND Ertapenem is a once-a-day carbapenem and has excellent activity against many gram-positive and gram-negative aerobic, facultative, and anaerobic bacteria. The susceptibility of isolates of community-acquired bacteremia to ertapenem has not been reported yet. The present study assesses the in vitro activity of ertapenem against aerobic and facultative bacterial pathogens isolated from...
