- Engorged sand flies were maintained on 50% aqueous sucrose solution till day 2 post-blood meal at 26°C and then tested by qPCR for presence and quantity of Leishmania donovani DNA. Sand flies fed on the inoculated ear were tested individually; sand flies fed on other parts of mice body were pooled for PCR analysis.
- p.i., post infection, pos. = positive pool, a-s, numbers of Leishmania detected by qPCR: a, 320; b, all <10; c, <10; d, 1652, 419, 643, 297; e, 430; o, 708, 21, 245, 27, 476, 4035, 24, 68; p, 1850, 211, 39, 3216, 74, 48, 162; q, 18, 143, 2161, 614; r, 20, 481, 5031, 50, 21, 171, 572, 228, 17; s, 279; f, 153, 113, 168, 404, 665; g, 69, 1286, 517; h, 1574, 37, 30, 11085, 1021, 15, 2844, 137, 64, 1815; i, 425, 100, 444, 1917, 2186; j, 273, 860, 50; k; 143, 180; l, 60, 1333; m, 146, 382, 40049, 66, 151, 1123; n, 256.
