[Epidemiology of enterobacteriaceae causing bloodstream infections in neonatal intensive care unit patients].
An increasing number of neonates require intensive care, and this population has a high risk of developing infections. The Enterobacteriaceae most commonly related to healthcare-associated infection in neonatal intensive care units (NICU) are Escherichia coli, Klebsiella spp and Enterobacter cloacae. ⋯ The study has provided better knowledge of bloodstream infections caused by Enterobacteriaceae in the NICU of our hospital from both the epidemiological and clonal standpoints.

[Selective decontamination of the digestive tract: repercussions on microbiology laboratory workload and costs, and antibiotic resistance trends].
This study determines the workload and cost of implementing selective digestive decontamination in the microbiology laboratory, and reports the impact on microbial flora and bacterial resistance trends in the intensive care unit (ICU). ⋯ In our hospital, implementation of selective digestive decontamination did not cause a significant increase in the workload or costs in the microbiology laboratory. Selective digestive decontamination was associated with a significant decrease in Acinetobacter, an increase in Enterococcus, and higher resistance to imipenem, tobramycin and ciprofloxacin in P. aeruginosa.

Review Case Reports[Brain abscess due to Listeria monocytogenes in adults: six cases and review of the literature].
Listeria monocytogenes is a gram-positive bacillus, with special tropism for the central nervous system (CNS). Brain abscess caused by Listeria has not been extensively studied, although it accounts for 10% of CNS infections due to this microorganism. ⋯ A high index of suspicion is needed to reach an early diagnosis and establish appropriate antibiotic treatment, which will improve the outcome of this condition. Suspicion is based on the presence of fever and neurological symptoms, particularly in immunodepressed or diabetic patients.

Comparative Study Clinical Trial[Comparison study of a real-time reverse transcription polymerase chain reaction assay with an enzyme immunoassay and shell vial culture for influenza A and B virus detection in adult patients].
The age of the patients and the type of sample are major problems in the diagnosis of influenza. Most available diagnostic techniques are highly effective in pediatric patients and in nasopharyngeal aspirates. However, in the adult population and using throat swabs, these techniques are much less reliable. ⋯ The real-time RT-PCR method studied displayed high sensitivity and specificity in the detection of influenza virus in adult patients, when compared with the conventional techniques. With real-time RT-PCR, large numbers of samples can be rapidly tested and results provided the same day samples are received.
