Benznidazole plus posaconazole therapy against VL-10 benznidazole resistant <i>Trypanosoma cruzi</i> stock.
<p>Maximum number of trypomastigote forms detected in the peripheral blood of mice infected with <i>Trypanosoma cruzi</i> VL-10 strain and treated with 100 mg/kg of bodyweight (mpk) of benznidazole (Bz) or 40 mpk of posaconazole (Ps) and with Bz plus Ps combination at the following dosages: 50 or 100 mpk of Bz in combination with 10 or 20 mpk of Ps for 20 consecutive days. Benznidazole was given daily and posaconazole twice a day (b.i.d.). IC – infected and untreated animals. a, b, c - different letters indicate significant differences, and the same letters indicates similar values among parasitemia levels.</p
