| biological characterization of trypanosoma cruzi stocks from domestic and sylvatic vectors in sierra nevada of santa marta, colombia. | sierra nevada of santa marta is one of the most endemic regions of chagas disease in colombia. in this study, we compared the biological behavior and genetic features of trypanosoma cruzi stocks that were isolated from domestic and sylvatic insects in this area. rhodnius prolixus (from domestic environments) and triatoma dimidiata (from sylvatic, peridomestic and domestic environments) are the most important vectors in this region. genetic characterization showed that all stocks corresponded to ... | 2008 | 18804443 |
| transmission dynamics of trypanosoma cruzi determined by low-stringency single primer polymerase chain reaction and southern blot analyses in four indigenous communities of the sierra nevada de santa marta, colombia. | this study attempted to evaluate the transmission dynamics of trypanosoma cruzi in four indigenous communities of sierra nevada de santa marta (snsm), colombia. low-stringency single primer-polymerase chain reaction (lssp-pcr) of the minicircles and southern blot analyses were used to characterize samples from patients, vectors, and reservoirs in these communities. the lssp-pcr profiles revealed a high genetic variability but with similarities among the parasites present in the samples of vector ... | 2009 | 19706903 |
| [population structure and genetic variability of rhodnius prolixus (hemiptera: reduviidae) from different geographic areas of colombia]. | rhodnius prolixus is the most important vector of chagas disease in colombia. genetic characterization of this species is useful to understand its potential of dispersion. the distribution of the vector and the genetic population structure are important factors for the adequate implementation of control programs and epidemiological surveillance of chagas disease. | 2007 | 18154243 |
