| [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 |
| vertebrate hosts and vectors of trypanosoma rangeli in the amazon basin of brazil. | a total of 46 trypanosoma rangeli stocks were isolated from naturally infected mammals and triatomine vectors. twenty-two stocks were from the common opossum (didelphis marsupialis), one from the brown "4-eyed" opossum (metachirus nudicaudatus), one from the anteater (tamandua tetradactyla), one from the coati (nasua nasua), seven from rhodnius pictipes and 14 from rhodnius robustus. two stocks were also isolated from recently fed sandflies (lutzomyia sp., shannoni group). the stocks were identi ... | 1983 | 6418015 |
| 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 |
| chagas' disease in the amazon basin: v. periurban palms as habitats of rhodnius robustus and rhodnius pictipes--triatomine vectors of chagas' disease. | trypanosoma cruzi infected rhodnius robustus and/or rhodnius pictipes were commonly found, in large numbers, in the brazilian amazonian palms maximiliana regia ("inajá"), acrocomia sclerocarpa ("mucajá") and orbignya speciosa ("babaçu"). the common opossum, didelphis marsupialis, was the animal most frequently associated with triatomine infested palms. r. pictipes, frequently light-attracted into houses from palm trees, was the probable source of an acute case of chagas' disease in the vicinity ... | 1983 | 6443629 |
