Figures & data

Figure 1. Molecular phylogenetic tree generated in this study by Maximum Likelihood based on Kimura 2- parameter (K2P + G) for CAL data set (A) and Tamura 3-parameter (T92 + I) for ITS1/2 + 5.8S data set (B) of S. schenckii complex species. The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1,000 replicates) is shown next to the branches (Bootstrap support values > 70% are indicated in bold). GenBank accession numbers are indicated next to strain code. Strains used in this study are indicated in bold type.

Figure 3. Colony count (CFU/g) comparison among different strains of S. schenckii s. str., and S. brasiliensis or S. globosa in spleen (A), lungs (B) and liver (C) obtained from infected BALB/c mice. Wide bars represent the mean CFU/g of tissue recovered from five mice and thin bars represent the standard deviation. *p < 0.05.
