Sequence-based genotyping of extra-intestinal pathogenic Escherichia coli isolates from patients with suspected community-onset sepsis, Sweden.

Extra-intestinal pathogenic Escherichia coli (ExPEC) strains are responsible for a large number of human infections globally. The management of infections caused by ExPEC has been complicated by the emergence of antimicrobial resistance, most importantly the increasing recognition of isolates producing extended-spectrum β-lactamases (ESBL). Herein, we used whole-genome sequencing (WGS) on ExPEC isolates for a comprehensive genotypic characterization.

Genotypic Characterization of Clinical spp. Isolates Collected From Patients With Suspected Community-Onset Sepsis, Sweden.

is a genus of Gram-negative bacteria known to be opportunistic pathogens that may cause a variety of infections in humans. Highly drug-resistant species, especially , have emerged rapidly and are becoming a major concern in clinical management. Although is considered the most important pathogen within the genus, the true clinical significance of the other species is likely underrecognized due to the inability of conventional microbiological methods to distinguish between the species leading to high rates of misidentification.

Expression of miRNAs in Bull Spermatozoa Correlates with Fertility Rates.

Bull spermatozoa are rich in active miRNAs, and it has been shown that specific spermborne miRNAs can be linked to fertility. Thus, expression profiling of spermatozoa could be helpful for understanding male fertility and the ability of spermatozoa to initiate and sustain zygotic, embryonic and foetal development. Herein we hypothesized that bulls with moderate to high fertility can be identified by differences in amounts of certain miRNAs between their ejaculates.

Dynamic modelling of cell death during biofilm development.

Biofilms are currently recognised as the predominant bacterial life-style and it has been suggested that biofilm development is influenced by a number of different processes such as adhesion, detachment, mass transport, quorum sensing, cell death and active dispersal. One of the least understood processes and its effects on biofilm development is cell death. However, experimental studies suggest that bacterial death is an important process during biofilm development and many studies show a relationship between cell death and dispersal in microbial biofilms.

Chronic kidney disease--a common and serious complication after intestinal transplantation.

Background: Chronic kidney disease after organ transplantation is a serious complication that negatively impacts on long-term patient survival. We describe long-term renal function after intestinal transplantation by serial measurements of glomerular filtration rates (GFR) with Chromium EDTA clearance.

Materials And Methods: Ten patients with at least 6 months survival form the basis of this report.
