A Phylogenomic Approach for the Analysis of Colistin Resistance-Associated Gene...

The emergence of carbapenemase-producing Klebsiella pneumoniae strains has triggered the use of old antibiotics such as colistin. This is driving the emergence of colistin resistance in multidrug-resistant strains that underlie life-threatening infections. This study analyses the mutational diversity of 22 genes associated with colistin resistance in 140 K. pneumoniae clinical isolates integrated in a high-reso...

Replicon typing of plasmids from Klebsiella pneumoniae and Escherichia coli cli...

Potential role of Escherichia coli common pilus (EcpA) in persistence of clinic...

Endemic clone Escherichia coli harboring ECP common pillus versus an outbreak c...

Plasmid-mediated CMY-2 AmpC beta lactamase and CTX-M-14 extended-spectrum beta-...

Direct application of the INNO-LiPA Rif.TB line-probe assay for rapid identific...

The INNO-LiPA Rif.TB assay for the identification of Mycobacterium tuberculosis complex strains and the detection of rifampin (RIF) resistance has been evaluated with 360 smear-positive respiratory specimens from an area of high incidence of multidrug-resistant tuberculosis (MDR-TB). The sensitivity when compared to conventional identification/culture methods was 82.2%, and the specificity was 66.7%; the sensit...

Case of aortic endocarditis caused by Lactobacillus casei

A case of Lactobacillus aortic valve endocarditis in a 53-year-old immunocompetent patient with past history of rheumatic fever is reported. Clinical symptoms began after a dental extraction and the patient's diet included several yogurts per day. Blood, bone marrow cultures and the replaced aortic valve were positive for Lactobacillus. The clinical isolate was identified as Lactobacillus casei by 16S rDNA sequ...

Diversity of chromosomal AmpC beta-lactamases from Enterobacter cloacae isolate...

Six clinical isolates of Enterobacter cloacae isolated in a Portuguese hospital, between April 1999 and November 2000, demonstrated resistance to almost all broad-spectrum cephalosporins, except to cefepime. These isolates were susceptible to quinolones and to aminoglycosides. lsoelectric focusing demonstrated production of beta-lactamases with pIs 8.0 and by all six isolates, exhibiting a cephalosporinase phen...

Multicenter study of isolated micro-organisms resistant to antimicrobials in 10...

In 1994, Microbiology Laboratories of ten Portuguese hospitals analysed isolated microorganisms found in blood and urine samples and studied antimicrobial susceptibilities of the most frequent bacterial pathogens. From 63780 blood samples, the most frequent were Staphylococcus spp. and from 69189 urine samples significant numbers of Escherichia coli, Enterococcus spp., Pseudomonas aeruginosa and Candida spp. we...

A case of Legionella pneumophila pneumonia.

Legionella pneumophila is an uncommon cause of pneumonia, mainly in children. We present a case with aggressive disease and unfavourable outcome. The diagnosis was established by serum antibody detection and immunofluorescence and culture of a fragment of lung tissue obtained at necropsy. We focus the importance of this aetiology in nosocomial pneumonia and community-acquired pneumonia with an atypical evolutio...
