Correlation analysis between parasite numbers and ARG activity in infected draining lymph nodes (LN).

<p>At various times after infection (A) BALB/c and (B) C57BL/6 mice infected with pathogenic (<i>L</i>. <i>major</i>: 2×10⁶ parasites/ml and <i>L</i>. <i>tropica</i>: 2×10⁷ parasites/ml) and non-pathogenic <i>Leishmania</i> (<i>L</i>. <i>tarentolae</i>: 2×10⁷ parasites/ml<i>)</i> promastigotes were sacrificed, and parasite numbers as well as ARG activity in the draining LNs was determined. Data reported are those of duplicate samples, and the experimental procedure was repeated at least two times with similar outcomes. Error bars are SD (**p≤ 0.01, ****p≤ 0.001 and *****p≤ 0.0001) (W: Week).
