Fig 9. Comparison of the susceptibility of P. argentipes and P. orientalis to L. donovani .
Females of P. argentipes (ARG) and P. orientalis (ORI) were infected by feeding on a suspension of 2×103 promastigotes/ml of blood and kept at 26°C. 9A: Females were examined microscopically on days 6 and 8 PBM. Intensities of infection were classified into three categories according to their intensity: light (< 100 parasites/gut), moderate (100 − 1000 parasites/gut), or heavy (> 1000 parasites/gut). Numbers above the bars indicate the number of dissected females. 9B: The number of parasites from 20 females of each group was measured individually by Q-PCR 8 days post infection.
