Staphylococcus chromogenes is a common skin commensal in cattle and has been identified as frequent cause of bovine mastitis intramammary infections. We have developed seven locus Multilocus Sequence Typing (MLST) scheme for typing S . Sequence-based systems, such MLST, application studies genetic diversity, population structure, epidemiology, including strain variation factor pathogenicity or ...
Tracking of sources of sporadic cases of campylobacteriosis remains challenging, as commonly used molecular typing methods have limited ability to unambiguously link genetically related strains. Genomics has become increasingly prominent in the public health response to enteric pathogens as methods enable characterization of pathogens at an unprecedented level of resolution. However, the cost o...
We aimed to evaluate the stability of the Chlamydia trachomatis multi locus VNTR analysis (MLVA-ompA) and multi sequence typing (MST) systems through multiple passages in tissue culture. Firstly, we analyzed the stability of these markers through adaptation of C. trachomatis to tissue culture and secondly, we examined the stability of a four-locus MLVA-ompA and a five-locus MST system after mul...
The notoriously multi-resistant Staphylococcus haemolyticus is an emerging pathogen causing serious infections in immunocompromised patients. Defining the population structure is important to detect outbreaks and spread of antimicrobial resistant clones. Currently, the standard typing technique is pulsed-field gel electrophoresis (PFGE). In this study we describe novel molecular typing schemes ...
BACKGROUND Multiple locus sequence typing (MLST) has become a central genotyping strategy for analysis of bacterial populations. The scheme involves de novo sequencing of 6-8 housekeeping loci to assign unique sequence types. In this work we adapted MLST to a rapid microfluidics platform in order to enhance speed and reduce laboratory labor time. METHODOLOGY/PRINCIPAL FINDINGS Using two integ...
The opportunistic yeast Candida glabratais increasingly refractory to antifungal treatment or prophylaxis and relatedly is increasingly implicated in health care-associated infections. To elucidate the epidemiology of these infections, strain typing is required. Sequence-based typing provides multiple advantages over length-based methods, such as pulsed-field gel electrophoresis (PFGE); however...
Molecular techniques such as spa typing and multilocus sequence typing use DNA sequence data for differentiating Staphylococcus aureus isolates. Although spa typing is capable of detecting both genetic micro- and macrovariation, it has less discriminatory power than the more labor-intensive pulsed-field gel electrophoresis (PFGE) and costly genomic DNA microarray analyses. This limitation hinde...
