This study evaluates the neurodevelopment of children living near contaminated mining industries during their first year of life. Participants from the city of Oruro (Bolivia) were prospectively recruited during pregnancy. Follow-up occurred between May 2007 and November 2009. Information about the socioeconomic status and medical history of the pregnant women were collected using questionnaire...

BACKGROUND Pesticides are of concern in Bolivia because of increasing use. Frequent intoxications have been demonstrated due to use of very toxic pesticides, insufficient control of distribution and sale and little knowledge among farmers of protective measures and hygienic procedures. METHOD Questionnaires were applied and blood tests taken from 81 volunteers from La Paz County, of whom 48 w...

Abstract: The United States Agency for Development in Bolivia (USAID/Bolivia) created in 2002 PROSALUD- Partners for Development Project (PfD) with the aim of improving the population's well-being. The project used three components: small grant scheme, technical assistance and database system management. Through the small grants scheme, the PfD supported a Community Participation Strategy (CPS)...

Triatoma guasayana and two putative cryptic species pertaining to T. sordida complex (named groups 1 and 2) occur in sympatry in the Bolivian Chaco. Using multilocus enzyme electrophoresis and subsequent genetic analysis, our work assesses their population distribution and dispersal capacity in domestic, peridomestic, and silvatic environments. Our collections by light trap in the silvatic envi...

Bolivia, a landlocked emerging country in South America, has one of the smallest networks in the whole Internet. Before the IXP implementation, delivering packets between national ISPs had to be sent them through international transit links. Being aware of this situation and looking for increasing the number of users, Bolivian government enacted a law to gather all national ISPs on a single IXP...

This article describes the development of an operant conditioning training program for 17 species of New World primates at the Bronx Zoo. To apply less invasive techniques to husbandry protocols, the study introduced behaviors-hand feeding, syringe feeding, targeting, scale and crate training, and transponder reading-for formal training to 86 callitrichids and small-bodied cebids housed in 26 s...

Triatoma infestans (Klug) is the main vector of Chagas' disease in the Southern Cone of Latin America between the latitudes 10° S and 46° S. The long-term effectiveness of the control campaigns is greatly dependent upon the vector population structure. Mitochondrial DNA (mtDNA) genes have been used in a number of T. infestans population genetic analyses. However, the maternally inherited marker...

The detection of two widespread Trypanosoma cruzi clonal genotypes (20 and 39) in feces of Bolivian specimens of the vector Triatoma infestans was performed by a combination of polymerase chain reaction and clone-specific DNA hybridization. The hybridization pattern of 186 PCR positive samples cf T. infestans feces collected in two Bolivian departments identified clone 20 in 74.2% and clone 39 ...

The last decades have witnessed a rapid increase in our knowledge about amphibian diversity, and a growing number of studies have focused on anuran larval stages. Tadpoles can provide key information for conservation issues and the understanding of amphibian evolution. Moreover, research in tadpoles has the potential to advance species delimitation in the diverse and still understudied Neotropi...
