Aspergillus galactomannan detection in comparison to a real-time PCR assay in serum samples from a high-risk group of patients.

Invasive aspergillosis (IA) is a severe infection with a 70% mortality rate. Aspergillus fumigatus is responsible for over 90% of those infections. The diagnosis of invasive aspergillosis is based on clinical sample culture and detection of fungal hyphae in histopathological examination.

Evaluation of the prevalence of insertion element IS16 in vancomycin-resistant enterococci strains of Enterococcus faecium isolated from transplantology patients from a Warsaw Hospital between 2010 and 2012.

The study included 79 vancomycin-resistant Enterococcus faecium (VRE) strains isolated from 33 patients after kidney (n = 19) or liver (n = 14) transplantation; these patients were hospitalized between 2010 and 2012. The strains were obtained from infected persons as well as from carriers. All examined strains were tested for the susceptibility to antimicrobials active against enterococci and for the presence of vanA and vanB genes as well as the presence of the insertion sequence IS16 considered as one of the markers of hospital-associated strains.
