Figure 2From: Decrease of virulence for BALB/c mice produced by continuous subculturing of Nocardia brasiliensis Evolution of mycetoma lesions in animals inoculated with T 130 (left) and re-inoculated with the T0 (right). Each point represents the mean of 30 animals; bars represent the standard deviation. An equal group of animals was inoculated with T0 (open circles). At twelve weeks after infection statistically significant differences were observed in both cases (P< 0.001 and P= 0.021).Back to article page
