| the microdistribution of isoenzymic strains of trypanosoma cruzi in southern bolivia; new isoenzyme profiles and further arguments against mendelian sexuality. | 132 trypanosoma cruzi stocks were collected in southern bolivia (99 stocks in tupiza, 33 in tarija), and were characterized using five enzymes (six loci). from these 132 stocks, a sample of 21 was studied using 10 enzymes (12 loci) to establish the genetic distances between them. only five different isoenzymic strains were registered among the 132 stocks: the taxonomic status of these strains is discussed. the distribution of the strains indicated that a founder effect was not a constant fact at ... | 1984 | 6237474 |
| phenotypic diversity of triatoma infestans at the microgeographic level in the gran chaco of argentina and the andean valleys of bolivia. | triatoma infestans (klug) is the main vector of trypanosoma cruzi, etiologic agent of chagas disease. the phenotype of the species varies at different geographic scales. the objective of this study was to compare the antennal phenotype of spatially close t. infestans populations and to evaluate its usefulness as a marker of exchange of individuals between populations. the antennal phenotype of 190 t. infestans from argentina and bolivia was analyzed using uni- and multivariate techniques. this s ... | 2008 | 18714865 |
| wild triatoma infestans, a potential threat that needs to be monitored. | the current persistence of triatoma infestans, and therefore of chagas disease transmission, in the andean valleys of bolivia and the gran chaco (precisely where wild populations of the vector are widespread), indicates a possible relationship between these two occurrences. this paper provides an overview of the current knowledge regarding wild t. infestans in bolivia. the different morphs of the wild vector, their known distributions and some traits of their biology and ecology are presented. p ... | 2009 | 19753459 |
