[Positive urine pneumococcal antigen test and vaccination].

Introduction And Objective: Although urine pneumococcal antigen is an useful test, it has false positives such as pneumococcal vaccination.

Material And Methods: Positive urine pneumococcal antigen in Hospital de Denia (January-February/2015). We studied epidemiological, radiological and microbiological variables as well as previous pneumococcal vaccination (neumo-23 and/or neumo-13).

[Use of different PCR-based techniques integrated into a non-tuberculous identification algorithm].

Introduction: The aim of the present work was to demonstrate the utility of a non-tuberculous mycobacteria (NTM) identification algorithm, which integrates different PCR-based techniques and basic phenotypic features. Moreover, the algorithm for pattern restriction analysis of hsp65 (hsp65 PRA) interpretation has been updated.

Methods: The workflow chosen consisted of the identification by a DNA hybridization probe method, followed by PCR-restriction enzyme analysis of hsp65 (hsp65 PRA) in those isolates that cannot be identified by hybridization probes.

Diagnostic accuracy of a 16S ribosomal DNA gene-based molecular technique (RT-PCR, microarray, and sequencing) for bacterial meningitis, early-onset neonatal sepsis, and spontaneous bacterial peritonitis.

The diagnostic accuracy of a 16S ribosomal DNA (rDNA) gene-based molecular technique for bacterial meningitis (BM), early-onset neonatal sepsis (EONS), and spontaneous bacterial peritonitis (SBP) is evaluated. The molecular approach gave better results for BM diagnosis: sensitivity (S) was 90.6% compared to 78.

Lymphadenopathy caused by Mycobacterium colombiense.

We report the case of a 3-year-old girl with lymphadenopathy caused by the recently described species Mycobacterium colombiense. M. colombiense is a nonpigmented slow grower that is included in the Mycobacterium avium complex.
