In comparison with HLA-matched sibling bone marrow transplants, unrelated donor transplants are associated with increased graft-versus-host disease and graft failure. This is likely in part due to HLA incompatibilities not identified by current matching strategies. High resolution DNA-based typing methods for HLA class II loci have improved donor selection and treatment outcome in unrelated don...
Seven international laboratories tested the recently proposed single-locus typing strategy for Aspergillus fumigatus subtyping for interlaboratory reproducibility. Comparative sequence analyses of portions of the locus AFUA_3G08990, encoding a putative cell surface protein (denoted CSP), was performed with a panel of Aspergillus isolates. Each laboratory followed very different protocols for ex...
Application of molecular typing methods to dermatophyte species that cause skin and nail infections.
Typing methods utilising DNA technology were applied to a collection of Trichophyton mentagrophytes and T. rubrum isolates from skin and nail infections. The methods included restriction enzyme analysis (REA), hybridisation with the DNA probe poly (dG-dT), randomly amplified polymorphic DNA (RAPD) by PCR and restriction analysis of a segment of PCR-amplified rDNA. All these tests successfully d...
In developed countries, Salmonella enterica subspecies 1 serovars Enteritidis and Typhimurium range among the most common causes of bacterial food-borne infections. The surveillance and typing of epidemic Salmonella strains are important tools in epidemiology. Usually, Salmonella enterica subspecies 1 serovars are differentiated by serotyping for diagnostic purposes. Further differentiation is ...
Latent fingerprints are commonly recovered from crime scenes using tape lifts. Advancements in the sensitivity of DNA testing allow for DNA profiles from these “touch”, tape lift samples to be obtained. One drawback to DNA typing of tape lifts is that the adhesive material on the tape may inhibit DNA recovery. The purpose of this study was to maximize the recovery of DNA from the adhesive mater...
Typing techniques are essential for understanding hospital epidemiology, permitting the elucidation of the source of infection and routes of bacterial transmission. Although DNA-based techniques are the "gold standard" for the epidemiological study of Pseudomonas aeruginosa, antibiotic profiles and biochemical results are used because they are easy to perform and to interpret and relatively ine...
AIM To evaluate trends in DNA typing success rates of different skeletal elements from mass graves originating from conflicts that occurred in the former Yugoslavia (Bosnia and Herzegovina and Kosovo) during the 1990s, and to establish correlation between skeletal sample age and success of high throughput short tandem repeat (STR) typing in the large data set of the International Commission on ...
The potential use of spoligotyping—a polymerase chain reaction based typing system for diVerentiation of strains of Mycobacterium tuberculosis—for studying the epidemiology of tuberculosis in developing countries which do not routinely perform mycobacterial culture is described in this issue of Thorax by Heyderman et al in a study from Zimbabwe. 1 How does this newer method compare with the now...
AIM To conduct developmental validation studies on a polymerase chain reaction (PCR) based short tandem repeat (STR) multiplex typing system, developed for the purpose of genetic individualization and parentage testing in domestic cat samples. METHODS To evaluate reproducibility of the typing system, the multiplex was amplified using DNA extracted from hair, blood, and buccal samples obtained...
