The automated sequencing of purified DNA fragments by spin columns (Qiagen, Chatsworth, Calif.) was performed by the cycle-sequencing dye terminator method. The Big Dye Terminator Cycle Sequencing Ready Reaction Kit (ABIPRISM 100, Applied Biosystems, Foster City, CA) was chosen for sequencing. The RG-7388 manufacturer sequences obtained were deposited in the GenBank database (AF856321-AF856328; AF856341-AF856350). Phylogenetic and Recombination studies TrN93 substitution
model was used to make the phylogenetic analysis since this model showed to be the best to analyze DENV sequences by using “”Model Selection”" implemented in “”DataMonkey”" [28, 29] The DENV-2 sequences of partial C91-prM-E-NS12400 genome (90) or E gene (180) were aligned using Clustal W ; keeping the more representative sequences (17 and 16 respectively) to obtain plots and phylogenies trees to evaluate recombination in our isolates and clones. The accession number of sequences selleck screening library are as follow: VEN_2_87 (AF100465), MEX_131-92(AF100469), THNH_P36_93 (AF022441), TH_CO390_99 (AF100462), BANGKOK_74 (AJ487271), NGC_44 (D00346), CHINA_43_89 (AF204178), CHINA_FJ_10_00 (AF276619), INDI_GWL102_01 (DQ448233), INDO_BA05i_05 (AY858035), INDO_ 98900666_04 (AB189124), BR_64022_02 Dichloromethane dehalogenase (AF489932),
JAM_N1409_83 (M20558), CHINA_04_85 (AF119661), DR_23_01 (AB122020), MART_703_98 (AF208496), CUBA_13_97 (AY702034), MEX_95 (DQ364562). The aligned sequences were analyzed by Recombinant Detection Program version 3 (RDP3)  using default parameters (window of 200nt, step of 20nt, Jin and Nei, 1990  substitution models and 1000 bootstrap) and by the
genetic algorithm for recombination detection (GARD) [52, 29].
