| type of rectal contents and infectivity of domiciliary populations of triatoma infestans (hemiptera: reduviidae) in argentina. | different types of rectal content in domiciliary populations of triatoma infestans (hemiptera: reduviidae: triatominae) were associated with differences in the degree of infection with trypanosoma (schizotrypanum) cruzi. field studies were carried out in a region of argentina (cordoba) where chagas' disease is endemic. the rectal contents of domiciliary t. infestans were classified by color (clear, yellow, or brown) and the number of infective metacyclic stages of t. cruzi. the seasonal percenta ... | 1995 | 7650696 |
| seroprevalence of trypanosoma cruzi infection and vector control activities in rural communities of the southern gran chaco (argentina). | we compared age-related seroprevalence of trypanosoma cruzi infection with history of vector control interventions and social and ecological changes in three historically endemic departments of cordoba province, argentina, covering an area of 42,600 km(2) of the gran chaco region. using a cross sectional design, blood samples of 5240 people between 6 months and 40 years of age, living in 192 rural communities were analyzed to detect t. cruzi infection using elisa tests, and confirmed with indire ... | 2010 | 19945420 |
| [modification of the perihabitational biotype in the prevention of chagas disease]. | in zones endemic for the american trypanosomiasis the modification of the biotopes surrounding human, rural, sylvatic or suburban housing, involves the arrangement of a clean perimetral area completely free of shrubs and chaparral, devoid of dens of wild animals and dwellings of domestic animals, to hinder the persistence of peridomestic foci where the proliferation of triatomine bugs encourage the reinfestation of the human lodgings. the success of insecticide spraying campaigns, even with simu ... | 1989 | 2517852 |
| [natural infection of calomys musculinus (rodentia, cricetidae) by trypanosoma cruzi]. | in the rural area of las higueras, río cuarto, córdoba, argentina, a trypanosoma was isolated from a wild rodent (c. musculinus). the trypanosome was classified as trypanosoma cruzi because of the following characteristics: morphology as described by hoare for the schizotrypanum sub-genus: thin shaped, pointed back end, nucleus placed approximately in the middle of the body, prominent and subterminal kinetoplast and short free flagellum. the size measurements were as follows: total lengh 22.02 + ... | 1977 | 408884 |
| [congenital chagas disease in córdoba, argentina: epidemiological, clinical, diagnostic, and therapeutic aspects. experience of 30 years of follow up]. | chagas'disease has a great epidemiological relevance. most of infected children are asymptomatics, with low mortality rate. the most frequent clinical findings are hepatomegaly and splenomegaly parasitological methods: fresh smears, microstrout and hemoculture, sequentially performed, detect the parasite in almost 100% of infected children. the gold standard for immunodiagnosis are serological curves, due to the interference of maternal igg. infected children maintain their antibody levels , whe ... | 2005 | 16482811 |
| isolation of beauveria bassiana (bals.) vuill. (deuteromycotina: hyphomycetes) from the chagas disease vector, triatoma infestans (hemiptera: reduviidae) in argentina. | a survey for natural entomopathogenic fungi of the chagas disease vector triatoma infestans was conducted in five provinces of argentina since 2001. nymphs (1.5%) and adults (3.3%) infected with a strain of the fungus beauveria bassiana were found at dean funes, cordoba province, argentina. field collected insects that died in the laboratory were maintained in moist chambers and incubated at 22 degrees c. beauveria bassiana from infected insects was cultured on sday media. pathogenicity tests we ... | 2005 | 15883724 |
| molecular phylogeography of the chagas' disease vector triatoma infestans in argentina. | triatoma infestans is the main vector of chagas' disease in south america between latitudes 10°s and 46°s. a multilocus microsatellite data set of 836 individuals from 27 populations of t. infestans, from all its range of distribution in argentina, was analyzed. our results favor the hypothesis of two independent migration events of colonization in argentina and secondary contacts. the majority of the populations of the western provinces of catamarca, la rioja, san juan and the west of cordoba p ... | 2011 | 21224874 |
| [the esophagus in patients with chagas disease in córdoba, argentina. histologico-immunohistochemical, and evacuation time]. | with the purpose of to establish the status of the oesophagus with respect to chagasic aendemia in subjects of the central rural zone of argentine, we search the esophagic evacuation duration-time by means of a radiologic standardized test which studied the ingested barium transit as well us the caliber of a given oesophagus. 87 chagasic subjects from rural zones of cordoba and santiago del estero, argentina, were studied. all had several positive serological test for chagas' infection. as contr ... | 1999 | 10883505 |
