Enterocytozoon bieneusi is the most common microsporidia that causes disease in immunocompromised hosts, especially in AIDS patients. E. bieneusi has been reported in a wide range of animals, including domestic, wild and farm animals. Using molecular typing and phylogenetic analysis, the zoonotic potential of E. bieneusi to cause disease is indeed a threat. Transmission from animals to humans s...

Pulsed-field gel electrophoresis (PFGE) is a valuable molecular typing assay used for methicillin-resistant Staphylococcus aureus (MRSA) surveillance and genotyping. However, there are several limitations associated with PFGE. In Alberta, Canada, the significant increase in the number of MRSA isolates submitted to the Provincial Laboratory for Public Health (ProvLab) for PFGE typing led to the ...

BACKGROUND Syphilis is resurgent in many regions of the world. Molecular typing is a robust tool for investigating strain diversity and epidemiology. This study aimed to review original research on molecular typing of Treponema pallidum (T. pallidum) with three objectives: (1) to determine specimen types most suitable for molecular typing; (2) to determine T. pallidum subtype distribution acros...

Background: Staphylococcus aureus is a common pathogen in human that can be the cause of a wide range of infectious diseases including bacteremia, pneumonia, cellulitis, and osteomyelitis and skin and soft tissue infections. The coagulase enzyme is one of the most important virulence factors of this bacterium. The polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) Coa...

We describe a novel, semiautomated Clostridium difficile typing platform that is based on PCR-ribotyping in conjunction with a semiautomated molecular typing system. The platform is reproducible with minimal intra- or interassay variability. This method exhibited a discriminatory index of 0.954 and is therefore comparable to more arduous typing systems, such as pulsed-field gel electrophoresis.

Epidemiologically linked clusters are confirmed by typing strains with molecular typing such as pulsed-field gel electrophoresis (PFGE). We compared six extended-spectrum β-lactamase producing E. coli of a PFGE-related cluster with Matrix-assisted laser desorption/ionization-time of flight mass-spectrometry based typing that confirmed relatedness faster and more cost-effective, but as reliable ...

Metagenomic characterization of microbial communities has the potential to become a tool to identify pathogens in human samples. However, software tools able to extract strain-level typing information from metagenomic data are needed. Low-throughput molecular typing schema such as Multilocus Sequence Typing (MLST) are still widely used and provide a wealth of strain-level information that is cu...

Background: Considering the role of HLA matching in transplant outcome, the quality of HLA-DR typing is clearly an important issue. In recent years, serological methods have been replaced with DNA based typing methods. The main objective of this study was to compare HLA-DR typing data obtained from existing serologic method with data obtained by the new PCR-SSP method. Methods: 55 peripheral bl...
