The number of nosocomial infections caused by Acinetobacter baumannii has increased in recent years. During a 12-month study, there were 1.8 episodes of A. Baumannii bacteremia per 1,000 adults admitted to a hospital in Seville, Spain. Seventy-nine patients were included in the study. A. baumannii bacteremia occurred after a mean (+/- SD) hospitalization of(More)
BACKGROUND Acinetobacter baumannii is a major cause of nosocomial infections in many hospitals and appears to have a propensity for developing multiple antimicrobial resistance rapidly. CASES We report two cases with post-surgical meningitis due to multidrug resistant A. baumannii which were successfully treated with high-dose intravenous meropenem(More)
The clinical features and the outcomes of eight cases of nosocomial Acinetobacter baumannii meningitis treated with ampicillin/sulbactam are reported. All the patients had fever, neck stiffness or meningeal signs, and a low consciousness level, and in their cerebrospinal fluid (CSF), pleocytosis, a low glucose level, and an elevated protein level were(More)
The mortality rate of patients with cases of enterococcal bacteremia is high, although it has often been related to the patients' underlying conditions rather than to the infection itself. To analyze the attributable prognosis of enterococcal bacteremia (assessed by its attributable mortality rate and duration of hospital stay), a prospective, matched(More)
Using a repetitive extragenic palindromic PCR (REP-PCR), we genotypically characterized strains causing nosocomial Acinetobacter baumannii infections and analyzed the source of bacteremia in 67 patients from an institution in which infections by this bacterium were endemic. Six different genotypes were found, including 21, 27, 3, 9, 3, and 4 strains. The(More)
A case ofLeuconostoc cremoris bacteremia in a patient with burn wounds over 45% of the body surface is presented.Leuconostoc bacteremia has not previously been reported in burn patients. The predisposing factors in this case were severe burn wounds resulting in immunocompromise, presence of both intravenous and enterai feeding catheters, several surgical(More)
 To determine the risk factors involved in the development of enterococcal bacteremia, a prospective, observational, case-control study was carried out over 18 months. All episodes of enterococcal bacteremia with clinical significance detected in adults were included. A control matched by sex, age and hospitalization ward (medical, surgical or intensive(More)
Sixteen amikacin-resistant clinical Acinetobacter baumannii isolates from nine different hospitals in Spain were investigated to determine whether the high incidence of amikacin-resistant A. baumannii was due to the dissemination of an amikacin-resistant strain or to the spread of an amikacin resistance gene. The epidemiological relationship studied by(More)
Pneumocystis carinii is a common opportunistic pathogen in patients infected with the human immunodeficiency virus (HIV).Pneumocystis carinii pneumonia is common, while extrapulmonary infections withPneumocystis carinii have been reported sparingly. The clinical features are frequently nonspecific. The detection ofPneumocystis carinii in cerebrospinal fluid(More)
BACKGROUND Healthcare-associated (HCA) bloodstream infections (BSI) have been associated with worse outcomes, in terms of higher frequencies of antibiotic-resistant microorganisms and inappropriate therapy than strict community-acquired (CA) BSI. Recent changes in the epidemiology of community (CO)-BSI and treatment protocols may have modified this(More)
