BACKGROUND Diagnostic study of vector ticks for different pathogens transmitted specifically have been done by Iranian old scientists working on the basis of biological transmission of pathogens. In this study we decided to confirm natural infection of different collected ticks from three different provinces of Iran. METHODS Ticks were collected from livestock (sheep, goats and cattle) during...

The strategy developed for sex determination in skeletal remains is to amplify the highly degraded DNA, by use of primers that span short DNA fragments. To determine sex of unembalmed human cadaveric skeletal fragments from Sokoto, North-western Nigeria, using Polymerase Chain Reaction (PCR). A single blind study of Polymerase Chain Reaction (PCR)-based sex determination using amelogenin gene a...

Amplification of a particular DNA fragment from a mixture of organisms by PCR is a common first step in methods of examining microbial community structure. The use of group-specific primers in community DNA profiling applications can provide enhanced sensitivity and phylogenetic detail compared to domain-specific primers. Other uses for group-specific primers include quantitative PCR and librar...
