| in vitro culture and biochemical characterization of six trypanosome isolates from peru and brazil. | six trypanosomatids isolated from different geographical areas from south america (peru and brazil) and different vectors and reservoir hosts (the triatomine panstrongylus chinai [tp1], triatoma infestans [tp2], rhodnius ecuadorensis [tp3], r. prolixus [tb1], didelphys marsupialis [tb2]), and one from a human asymptomatic patient [tb3], were characterized using lectin agglutination, isoenzyme profile, in vitro culture final metabolite patterns, and compared with a reference strain (trypanosoma c ... | 2002 | 12615163 |
| chromosomal evolution trends of the genus panstrongylus (hemiptera, reduviidae), vectors of chagas disease. | the genus panstrongylus includes 14 species widely distributed from mexico to argentina, some of them with great epidemiological significance as vectors of chagas disease. we study the karyotype and the male meiotic process of panstrongylus chinai, p. geniculatus, p. herreri, p. lignarius, p. megistus, p. rufotuberculatus and p. tupynambai. all species present the same sex mechanism (x(1)x(2)y in males and x(1)x(1)x(2)x(2) in females) and they also have 20 autosomes, with the exception of p. meg ... | 2002 | 12798000 |

| high household infestation rates by synanthropic vectors of chagas disease in southern ecuador. | entomological surveys were conducted in five rural communities (138 domiciliary units [dus]) in the southern andes of ecuador. adobe walls and ceramic tile roofs were predominant construction materials. a 35% house infestation rate with panstrongylus chinai (del ponte, 1929) (0.7%), panstrongylus rufotuberculatus (champion, 1899) (0.7%), rhodnius ecuadoriensis (lent & león, 1958) (27%), and/or triatoma carrioni (larrousse, 1926) (7%) was found. adults and nymphs of r. ecuadoriensis and t. carrio ... | 2005 | 15691011 |
| life cycle, feeding, and defecation patterns of panstrongylus chinai (hemiptera: reduviidae: triatominae) under laboratory conditions. | chagas disease is caused by the protozoan trypanosoma cruzi panstrongylus chinai (del ponte) is highly domiciliated in the peruvian and ecuadorian andes and has been found naturally infected with t. cruzi the objective of this study was to describe the life cycle, feeding, and defecation patterns of p. chinai in the loja province within southern ecuador. to characterize its life cycle, a cohort of 70 individuals was followed from egg to adult. at each stage of development, prefeeding time, feedi ... | 2016 | 27131311 |
| comprehensive survey of domiciliary triatomine species capable of transmitting chagas disease in southern ecuador. | chagas disease is endemic to the southern andean region of ecuador, an area with one of the highest poverty rates in the country. however, few studies have looked into the epidemiology, vectors and transmission risks in this region. in this study we describe the triatomine household infestation in loja province, determine the rate of trypanosoma cruzi infection in triatomines and study the risk factors associated with infestation. | 2015 | 26441260 |
| salivary gland transcripts of the kissing bug, panstrongylus chinai, a vector of chagas disease. | the saliva of hematophagous arthropods injected during blood feeding contains potent pharmacologically active components to counteract the host hemostatic and inflammatory systems. in the present study, dominant salivary gland transcripts of panstrongylus chinai, a vector of chagas disease, were analyzed by sequencing randomly selected clones of the salivary gland cdna library. this analysis showed that 56.5% of the isolated transcripts coded for putative secreted proteins, of which 73.7% coded ... | 2017 | 28690145 |
| the modern morphometric approach to identify eggs of triatominae. | egg morphometrics in the triatominae has proved to be informative for distinguishing tribes or genera, and has been based generally on traditional morphometrics. however, more resolution is required, allowing species or even population recognition, because the presence of eggs in the domicile could be related to the species ability to colonize human dwellings, suggesting its importance as a vector. | 2017 | 28143573 |
| salivary lipocalin family proteins from panstrongylus chinai, a vector of chagas disease. | the dataset in this report is related to the research article with the title: "salivary gland transcripts of the kissing bug, panstrongylus chinai, a vector of chagas disease" (kato et al., 2017) [1]. lipocalin family proteins were identified as the dominant component in p. chinai saliva, and phylogenetic analysis of the salivary lipocalins resulted in the formation of five major clades. for further characterization, each clade of p. chinai lipocalin was s alignment and phylogenetic analyses tog ... | 2017 | 29034292 |
| identifying trypanosoma cruzi discreet typing units in triatomines collected in different natural regions of perú. | trypanosoma cruzi has been divided by international consensus into six discrete typing units (dtu): tci, tcii, tciii, tciv, tcv y tcvi. the factors determining the dynamics of t. cruzi genotypes vector transmission of chagas' disease in the different geographical regions of perú are still unknown. | 2017 | 29161488 |
