Personal Identification by DNA Typing
نویسنده
چکیده
The short tandem repeat (STR) polymorphisms are highly useful tools for personal identification and paternity testing in forensic practice. Sequence analysis of mitochondrial DNA (Mt DNA) is being used to characterize forensic biological specimens, particularly when there is insufficient nuclear DNA in samples for typing. Bones, teeth and other samples that are severely decomposed may be subjected to Mt DNA analysis. We could successfully apply these techniques to investigate samples from practical forensic cases and confirming their efficacy for forensic practice.

PCR Typing of Trichophyton Rubrum Isolates by Specific Amplification of Subrepeat Elements in Ribosomal DNA Nontranscribed Spacer
Background: Trichophyton rubrum (T. rubrum) is the most common cause of dermatophytosis of skin and nail tissue. Strain identification in Trichophyton rubrum is important for identification of strain-related differences in infectivity potential or transmissibility and epidemiological studies. PCR typing could determine whether the original isolate is responsible for re-infection or a new strain...
متن کاملMolecular identification and capsular typing of Pasteurella multocida isolates from sheep pneumonia in Iran
Pasteurella multocida is known as one of the main organisms causing pneumonia in sheep. As immunity in pasteurellosis is serogroup specific, identification of prevalent capsular group among endemic areas is essential. The aim of this study was to molecular identification and determine of the capsular type of the P. multocida strains isolated from sheep pneumonia in Iran. Bacteriological and bio...
متن کاملIdentification of Human Decomposed Remains Using the STR Systems: Effect on Typing Results
This report covers our starting experience on the DNA identification of the post-mortem remains recovered from the battlefields, and illustrates some effects on typing results when STR systems are used for DNA typing of decomposed human remains. This study is primarily concerned with the amplification of degraded DNA samples. Reports of identification by family studies will be presented elsewhere.

Clostridium perfringens is an important pathogen that provokes numerous different diseases. This bacterium is classified into five various types, each of which capable of causing a distinct disease. There are various methods for the bacterial identification, many are labor-intensive, time-consuming, expensive and also show low sensitivity and specificity. The aim of this research was to identif...
متن کاملValidation of multiplex polymorphic STR amplification sets developed for personal identification applications.
Polymorphic short tandem repeat (STR) loci, which typically consist of variations in the number of 3-7 base pair repeats present at a site, provide an effective means of personal identification. Typing can be accomplished by amplification of genomic DNA using the polymerase chain reaction (PCR) and locus-specific primers, separation of amplified alleles using gel electrophoresis and their displ...
