Genetic network of spoligotypes detected in Venezuela using parsimony principles and the Biolayout software. Each black arrow represents a phylogenetic link between two spoligotypes differing by a genetic change. The size of the circles representing the spoligotypes is proportional to the number of isolates in each cluster. Prevalent phylogenetic clades in Venezuela: LAM (2-9-5); T-1; Haarlem (H-1) and S are named. See text for details.
