Fig 1

Phylogeny of filarid of the Marajó mesoregion.

The cladogram was inferred using the Maximum Parsimony method. It contains a length of 266, the consistency index is 0.614458 and the retention index is 0.872170. The Bootstrap is indicated next to the knots of the branches. The sequence of the obtained samples were grouped in two clades: In clade I, 30 sequences of the municipalities Soure, Chaves, Portel, Anajás São Sebastião da Boa Vista formed a politomy with A. reconditum (AF217801.2), with Bootstrap of 73%. Clade II is composed by 9 sequences of Soure and Chaves municipalities, which form a polytomy with D. immitis (EU182330.1) withal 83% of Bootsrap. The other filarid sequences remained in isolated branches: D. dracunculoides (DQ018785.1) as a brother group of A. reconditum (Bootstrap 96%) and D. repens (AY693808.1) most related to D. immitis (Bootstrap 96%). A. lumbricoides (AB571301.1) and T. trichiura (KC877992.1) are the outgroup.
