Figure 5. Parasite burden in hamsters experimentally infected with two strains of L. infantum (PP75 and Wild) by different routes of inoculation.

Figure 5

Number of amastigotes deduced from the qPCR data by the total weight of the liver (A) and spleen (B) in hamsters experimentally infected with two strains of L. infantum (PP75 or Wild) by different routes of inoculation: intradermal (ID, n = 80; light gray), intraperitoneal (IP, n = 80; dark gray), and intracardiac (IC, n = 80; black) after 1, 3, 6, and 9 months of infection. The results are expressed as mean ± standard deviation. Significant differences (p<0.05) between infection with the different routes of inoculation are represented by the letters “a” and “b” related to the group ID and IP, respectively.
