Urinary Tract Infections in Kidney Transplant Recipients Hospitalized at a Transplantation and Nephrology Ward: 1-Year Follow-up.

Introduction: The aim of this study was to investigate risk factors for urinary tract infections (UTI), the causative organisms of UTI and also their management and treatment. In addition, we evaluated the effects of UTI on renal graft function.

Methods: This analysis included 107 kidney transplant recipients (64% women) with a diagnosis of UTIs confirmed by positive results on urine culture.

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.

Strains of Klebsiella pneumoniae producing extended spectrum beta-lactamases, isolated from organ recipients.

Objective: The aims of this work were to define the effectiveness of identification of the extended-spectrum beta-lactamases (ESBL) phenotype, and to define the genotype of Klebsiella pneumoniae β-lactamase.

Materials And Methods: We identified ESBL phenotypes in 110 strains of K pneumoniae isolated from samples from patients of transplantation wards, using the double-disk synergy test (DDST). For the chosen strains, polymerase chain reaction (PCR) was applied to detect genes determining SHV, CTX-M, and TEM.

Comparison of bacteria isolated from urinary tract infections in patients on transplant versus urologic wards.

Objective: Urinary tract infections (UTI) are the most common hospital infections. Complications include sepsis and shock. Immunosuppressed transplant surgery patients may experience loss of the graft due to UTI.

[Modification and optimization of PCR methods for detection of MIE region from human herpesvirus 5].

Human herpesvirus 5 (HHV-5, formerly known as CMV) is a beta-herpesvirus widely spread within a population. Thus, HHV-5 infections are a serious matter of concern in a group of immunocompromised patients. The goal of the study was modification and optimization of conventional PCR method developed for the detection of HHV-5 DNA to the real-time variant (RTmPCR) and determination of analytical resolution of the modified methods.
