| sylvatic american trypanosomiasis in argentina. trypanosoma cruzi infection in mammals from the chaco forest in santiago del estero. | trypanosoma cruzi infection in sylvatic mammals of the quebracho woods of the eastern part of santiago del estero province, argentina, was studied from october 1984 to december 1987. 301 mammals of 20 different species were caught. t. cruzi, characterized biologically and biochemically, was isolated by xenodiagnosis from 23 of 72 (32%) didelphis albiventris opposums, 2/36 (5.5%) conepatus chinga skunks, and one ferret (galictis cuja). 53 opossum refuges were located and triatomine bugs were foun ... | 1992 | 1566301 |
| long-term reduction of trypanosoma cruzi infection in sylvatic mammals following deforestation and sustained vector surveillance in northwestern argentina. | long-term variations in the dynamics and intensity of sylvatic transmission of trypanosoma cruzi were investigated around eight rural villages in the semiarid argentine chaco in 2002-2004 and compared to data collected locally in 1984-1991. of 501 wild mammals from 13 identified species examined by xenodiagnosis, only 3 (7.9%) of 38 didelphis albiventris opossums and 1 (1.1%) of 91 conepatus chinga skunks were infected by t. cruzi. the period prevalence in opossums was four-fold lower in 2002-20 ... | 2006 | 16839513 |
| a comparative study of trypanosoma cruzi infection in sylvatic mammals from a protected and a disturbed area in the argentine chaco. | understanding the complex epidemiology of trypanosoma cruzi transmission cycles requires comparative studies in widely different environments. we assessed the occurrence of t. cruzi infection in sylvatic mammals, their infectiousness to the vector, and parasite genotypes in a protected area of the argentine chaco, and compared them with information obtained similarly in a nearby disturbed area. a total of 278 mammals from >23 species in the protected area were diagnosed for t. cruzi infection us ... | 2016 | 26708994 |
