Detection of sylvatic dark morphs of Triatoma infestans in the Bolivian Chaco
(Mem. Inst. Oswaldo Cruz, 1997)
Triatoma infestans, the most important vector of Chagas disease in the southern part of Latin America, is considered to originate from the Cochabamba valley in Bolivia because this is the only region where true sylvatic ...
Impairment of monocytic function during Trypanosoma cruzi infection
(Clinical and Diagnostic Laboratory Immunology, 1994-11)
During acute infection, Trypanosoma cruzi, the etiologic agent of Chagas' disease, causes immunosuppression by mechanisms that are not fully delineated. Since mononuclear phagocytes are major target cells in trypanosomiasis, ...
In vitro lymphocyte-differentiating effects of thymulin (Zn-FTS) on lymphocyte subpopulations of severely malnourished chidren
(Am J Clin Nutr, 1994)
ABSTRACT. This work investigates how thymic dysfunction contributes to the depression of cell-mediated immunity in protein-energy malnutrition (PEM). In Bolivian children hospitalized for severe PEM, the size of the thymus ...
High correlation between Chagas' disease serology and PCR-based detection of Trypanosoma cruzi kinetoplast DNA in Bolivian children living in an endemic area
(FEMS Microbiology Letters, 1994)
Abstract. The detection of Trypanosoma cruzi kinetoplast DNA by polymerase chain reaction (PCR) amplification is a potentially powerful tool for the parasitological diagnosis of Chagas’ disease. We have applied this technique ...
Developmental, genetic, and environmental components of aerobic capacity at high altitude
(American Journal of Physical Anthropology, 1995)
Abstract.
The aerobic capacity of 268 subjects (158 males and 110 females) was evaluated in La Paz, Bolivia situated at 3,750 m. The sample included 1) 39 high altitude rural natives (all male); 2) 67 high altitude urban ...
Risk factors for onset of cutaneous and mucocutaneous Leishmaniasis in Bolivia
(American Journal Tropical Medicine and Hygiene, 1997)
Abstract.
A survival analysis was performed on data from an endemic area of Bolivia where two populations, natives and highland migrants, were living, to investigate risk factors for onset of cutaneous leishmaniasis (CL) ...
The use of morphometrics in entomological surveillance of sylvatic foci of Triatoma infestans in Bolivia
(Acta Tropica, 1997)
Abstract
Jamach'uma (Cochabamba, Bolivia) is a small village surrounded by sylvatic foci of Triatoma infestans. Houses in the village were also infested with T. infestans, and were sprayed in December 1992 as part of a ...
Isoenzymes as a tool for the identification of Rhodnius species (Hemiptera: reduviidae: Triatominae)
(Research and Reviews in Parasitology, 1996)
ABSTRACT.
Some species of Rhodnius prove difficult to separate on overt morphological characters. leading to difficulties in determining the current distribution of several of the most epidemiologically significant species. ...
The effect of high altitude on platelet counts, thrombopoietin and erythropoietin levels in young Bolivian airmen visiting the Andes
(Int J Biometeorol, 1999)
Abstract.
Recognition of thrombosis as a complication of exposure to high altitude has stimulated interest in rheological changes resulting from hypobaric hypoxia. Previous studies of platelet counts at high altitude have ...
