Two highly discriminatory fingerprinting assays, short tandem repeat typing and amplified fragment length polymorphism (AFLP), were compared to determine the genetic relatedness between 55 isolates of Aspergillus fumigatus obtained from 15 different patients suffering from proven invasive aspergillosis. Both techniques showed that interpatient isolates belonged to different genotypes and that i...

DNA typing with short tandem repeat (STR) markers is now widely used for a variety of applications including human identification. Capillary electrophoresis (CE) instruments, such as the ABI Prism 310 and ABI 3100 Genetic Analyzers, are the method of choice for many laboratories performing STR analysis. This review discusses issues surrounding sample preparation, injection, separation, detectio...

The advent of microfluidic technology for genetic analysis has begun to impact forensic science. Recent advances in microfluidic separation of short-tandem-repeat (STR) fragments has provided unprecedented potential for improving speed and efficiency of DNA typing. In addition, the analytical processes associated with sample preparation--which include cell sorting, DNA extraction, DNA quantitat...
Introduction: Genetic identification is now a standard and efficient method for identifying individuals and investigating claimed kinship cases. Commercial kits based on autosomal STR and YSTR genetic markers are widely used for these investigations. Case Report: Two men were introduced by a judicial authority for genetic testing to identify and issue birth certificates for these individual...
Abstract Background and Objective: A high level of homogeneity observed within all bacteria in the Mycobacterium tuberculosis complex makes a property that seriously challenges traditional biochemical-based identification methods of these pathogens in the laboratory. The work presented here was conducted to characterize Mycobacterium tuberculosis complex isolates in Golestan, Northern Iran. ...
Mycoplasma bovis is an important veterinary pathogen causing pneumonia, arthritis, and mastitis in infected cattle. We investigated the genetic diversity of 53 isolates collected in the United Kingdom between 1996 and 2002 with pulsed-field gel electrophoresis (PFGE), amplified fragment length polymorphism (AFLP), and random amplified polymorphic DNA (RAPD) analysis. In addition, the influence ...
Salmonella enterica serovar Typhi is a clone with a low level of variation. We developed a molecular typing method for serovar Typhi using 38 genome-wide single-nucleotide polymorphisms (SNPs) as markers detected by PCR-restriction enzyme digestion. The 73 worldwide serovar Typhi isolates studied were separated into 23 SNP profiles and four distinct genetic groups. Serovar Typhi isolates expres...
Background and aim: Staphylococcus aureus can colonizes variety of body sites such as skin, coetaneous membrane and especially anterior nares. The coagulase gene (coa) typing is a technique in which the organism is typed based on the polymorphic region of the coa gene. The aim of the present study was to determine the coa based typing of S. aureus isolates from health care workers in two teach...
