Preliminary evaluation of a new kit for differentiation of Mycobacterium tuberculosis complex species using Speed-Oligo MTBC.

We present the first evaluation of a novel molecular assay, the Speed-Oligo Mycobacterium tuberculosis complex (SO-MTBC), which is based on PCR combined with a dipstick for the differentiation of M. tuberculosis complex (MTBC) members. The results of this assay were compared with findings obtained using the Genotype MTBC assay.

Molecular characterization and antimicrobial susceptibility of hemolytic Streptococcus agalactiae from post-menopausal women.

Purpose: Streptococcus agalactiae (Group B streptococcus, GBS) is increasingly recognized as a pathogen in adult populations, including the elderly. Appropriate treatment involves antibiotics. An alternative to this strategy would be the administration of a polysaccharide vaccine therefore the capsular serotypes and molecular characterization of circulating strains needs to be known.

[Serotypes and antibiotic resistance patterns in beta-hemolytic Streptococcus agalactiae isolates in colonized mothers and newborns with invasive disease].

Introduction: Current preventive measures against neonatal disease caused by Streptococcus agalactiae (GBS) are prenatal screening and intrapartum antibiotic prophylaxis with appropriate antimicrobials. An alternative to this strategy would be the administration of a polysaccharide vaccine as the distribution of capsular serotypes of circulating strains needs to be known.

Methods: A study was made of 188 strains from pregnant women carrying GBS and 24 newborns with neonatal disease.
