| [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 |
| dispersive flight by triatoma infestans under natural climatic conditions in argentina. | male and female t. infestans were released on two consecutive nights in the salinas of cordoba province, argentina, when air temperatures during the flying period averaged 28.5 degrees c. 136 males (43% of the total released) and 170 females (57%) flew on the first night, and 6 males (18%) and 7 females (27%) on the second. of these, we recovered 23 males and 14 females within 100 m, and a further female within 200 m, all from the first night's release. the remainder appear to have flown more th ... | 1992 | 1600228 |

| 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 |
| short report: variation in mitochondrial 12s and 16s ribosomal dna sequences in natural populations of triatoma infestans (hemiptera: reduviidae). | mitochondrial dna sequences of the 12s and 16s ribosomal rna genes were analyzed in five natural populations of the chagas' disease vector triatoma infestans from argentina. dna sequence comparisons of 878 basepairs (12s plus 16s) revealed 13 haplotypes. a total of 10 private haplotypes were found in four of the populations analyzed, suggesting low current levels of genetic exchange. the levels of genetic differentiation between the population of chancaní (córdoba) and other two of the populatio ... | 2003 | 12887028 |
| 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 |
