| [wild vectors of chagas' disease in an urban area of manaus (am): flying activity during dry and rainy seasons]. | adults of rhodnius prolixus, r. pictipes and panstrongylus geniculatus found in houses in manaus have high rates of trypanosoma cruzi infection. rhodnius spp. were found throughout the year, but males of p. geniculatus were significantly more frequent in the dry season. | 1998 | 9477705 |
| [occurrences of triatomines in wild and domestic environments in the municipality of manaus, state of amazonas]. | analysis of the distribution of triatomines is essential for formulating control strategies for chagas disease in the amazon region. in this paper, the results from trapping in wild and artificial environments in rural and urban localities in manaus, amazonas, are presented. out of the 115 triatomines collected, 85 (73.9%) were of the species rhodnius pictipes, 25 (21.7%) of rhodnius robustus and five (4.4%) of panstrongylus geniculatus. the rate of natural infection by flagellates was 5.9% for ... | 2009 | 20209347 |
| chagas' disease in the amazon basin iv. host records of trypanosoma cruzi zymodemes in the states of amazonas and rondonia, brazil. | of 151 trypanosoma cruzi stocks from 117 different individual hosts collected in the states of amazonas and rondonia, 147 from 113 hosts were identified as zymodeme 1 (z1). these included t. cruzi stocks from three marsupial species, two rodent species and three triatomine species although most were from the common opossum, didelphis marsupialis. one t. cruzi stock from rhodnius robustus was identified as z1 with a z3 pgm character, one from sciurus sp. as z3 and two from monodelphis brevicaudat ... | 1984 | 6441530 |
| attraction of chagas disease vectors (triatominae) to artificial light sources in the canopy of primary amazon rainforest. | adult triatomines occasionally fly into artificially lit premises in amazonia. this can result in trypanosoma cruzi transmission to humans either by direct contact or via foodstuff contamination, but the frequency of such behaviour has not been quantified. to address this issue, a light-trap was set 45 m above ground in primary rainforest near manaus, state of amazonas, brazil and operated monthly for three consecutive nights over the course of one year (432 trap-hours). the most commonly caught ... | 2010 | 21225207 |
