| genetic variability and microdistribution of triatoma infestans genotypes and trypanosoma cruzi clones in arequipa region (peru). | the genetic variability of triatoma infestans and trypanosoma cruzi populations was studied by isoenzyme analysis in two distinct areas of arequipa province (peru); one, santa rita de siguas, being an endemic area for chagas' disease, the second, arequipa, recently infected. analysis of t. infestans genetic variability indicates, (i) temporal stability of genotypes found in santa rita de siguas, (ii) high genetic differences between arequipa and santa rita de siguas populations suggesting minor ... | 1997 | 9332609 |
