| biological characterization of a strain of trypanosoma cruzi chagas isolated from a human case of trypanosomiasis in california. | in august 1982, the first autochthonous case of human american trypanosomiasis in california occurred. the isolate, the tuolumne strain of trypanosoma, was infective to young laboratory mice and capable of causing death or chronic disease in these animals. the morphology and mensural characteristics are described. this strain can develop in 2 species of triatominae native to california, triatoma protracta and t. rubida. the flagellates isolated from these insects were infective to vertebrate hos ... | 1989 | 2508500 |
| epizootiology of trypanosoma cruzi in southwestern north america. 8. nocturnal flights of triatoma protracta (uhler) as indicated by collections at black light traps (hemiptera: reduviidae: triatominae). | | 1966 | 5941571 |
| infection rates of triatoma protracta (uhler) with trypanosoma cruzi in southern california and molecular identification of trypanosomes. | we report trypanosoma cruzi infection rates of the native kissing bug triatoma protracta in southern california. the rates are within the historically reported range, but differ significantly between the two sites (19% in escondido and 36% in glendora). identification of t. cruzi in t. protracta was conducted for the first time by using partial 18s ribosomal rna and 24sα ribosomal rna sequences. incongruence of 24sα ribosomal rna phylogeny with current t. cruzi genotype classification supports n ... | 2010 | 21036830 |
| agent of chagas' disease from honduran vector capable of developing in california insects: implications for cardiologists. | an exotic strain of trypanosoma cruzi recovered from triatoma dimidiata from tegucigalpa, honduras, was shown by isoenzyme studies to be closely related to the miles' zymodeme 1 and laboratory reference strain tehuantepec. it was injected into swiss random-bred icr mice. clean triatoma protracta nymphs and adults, which had been captured in winters, california, fed on inoculated mice and were then examined over a 15-month period. their feces contained multiplying epimastigote and infective trypo ... | 1985 | 3929580 |
| human and sylvatic trypanosoma cruzi infection in california. | in august 1982, a 56-year-old woman from lake don pedro, california, developed acute chagas' disease (american trypanosomiasis). she had not traveled to areas outside the united states with endemic chagas' disease, she had never received blood transfusions, and she did not use intravenous drugs. trypanosoma cruzi cultured from the patient's blood had isoenzyme patterns and growth characteristics similar to t. cruzi belonging to zymodeme z1. triatoma protracta (a vector of trypanosoma cruzi) infe ... | 1985 | 3919598 |
| exotic stock of trypanosoma cruzi (schizotrypanum) capable of development in and transmission by triatoma protracta protracta from california: public health implications. | a stock of trypanosoma cruzi was recovered from a triatoma dimidiata from tegucigalpa, honduras. this stock was shown to be capable of development and transmission by native california triatoma protracta protracta. isozyme analysis indicated that this t. cruzi is closely related to the tehuantepec strain and to a lesser extent the miles' zymodeme 1 strain. the potential public health significance of development and transmission of exotic stocks of t. cruzi by native reduviids is discussed. | 1987 | 3107409 |
