Fig. 1From: Quantification by real-time PCR of Trypanosoma cruzi DNA in samples of Triatoma infestans used in xenodiagnosis of chronic Chagas disease patientsAmplified products of Trypanosoma cruzi by PCR in fecal samples of human xenodiagnosis. GelRed™ stained 2 % agarose gel of amplified products of Trypanosoma cruzi minicircle kinetoplastid PCR from fecal samples (FS) of triatomines (Triatoma infestans) fed on untreated chronic chagasic patients (PCR-XD). Lane C: control; Lane M: 100 bp ladder; Lanes 1-10: PCR-XD positive in ten patients (band of 330 bp specific for T. cruzi); Lane NC: FS-DNA extracted from five triatomines free infection; Lane PC: DNA T. cruzi Tulahuén strainBack to article page
