Use of DNA barcoding may be paramount to fighting lymphatic filariasis (LF), a parasite that has disfigured more than 40 million people worldwide and threatens 1 billion more across 80 countries. Researchers at the University of Ghana are spearheading the usage of DNA barcodes to map the various mosquito species spreading LF. Barcoding of a species is done by extracting a succinct DNA sequence from a specific region within the genome. This technique is especially useful since it would otherwise be very difficult to distinguish between the mosquito species; precise identification is necessary, as different mosquitoes have different transmission patters for LF. This is a promising development in LF treatment and will hopefully facilitate efforts in its elimination from West Africa.
