sentences:  Due to the large amount of lineages and different host species, a public database called MalAvi has been created to encourage sharing these sequences and aid in understanding the diversity of these parasites.Considering that no other genetic markers have been developed for this group of parasites, a ~1.2-4% sequence divergence has been determined as a cutoff value to distinguish between different parasite lineages.The molecular approach has also allowed direct comparisons between host phylogenies and parasite genealogies, and significant co-speciation has been found based on event-based-matching of phylogenetic trees.
