From the twig tips to the deeper branches: new insights into evolutionary history and phylogeography of Ascaris

摘要: Abstract To better understand the epidemiology of ascariasis, molecular genetic methods have been applied to differentiate between worms found infecting people and pigs, other occasional hosts. Owing difficulties in applying species concepts, longstanding debate distinction(s) Ascaris lumbricoides suum continues. From an perspective, however, markers help “tag” “track” during their transmission cycle(s), providing new insights into host range, as well for assessing parasite population dynamics through time contingent upon disease control. While useful determining at tips evolutionary tree, these tools also provide deeper branches. Although is throughout globe, analysis retrieved from sub-Saharan Africa point towards a significant center diversity, possibly denoting likely origin with subsequent diaspora. Resolving issues precisely, requires greater scrutiny variation within Parascaris Baylisascaris.
