Chagas disease in dogs from endemic areas of Costa Rica
(Memórias do Instituto Oswaldo Cruz, 2002-06)
Dogs with the presumptive diagnosis of Chagas disease are commonly sent to our School of Veterinary Medicine by independent veterinarians. This prompted us to evaluate the prevalence of canine trypanosomiasis in some ...
Chagas' disease: Risk factors for house infestation by Triatoma dimidiata, the major vector of Trypanosoma cruzi in Costa Rica
(The Johns Hopkins University School of Hygiene and Public Health., 1991)
The reduction of domiciliary infestation by insect vectors, the key to controlling Chagas' disease, depends on identification of housing features associated with infestation. In this study, log-linear modeling was used to ...
Ecological control of Triatoma dimidiata (Latreille, 1811): five years after a Costa Rican pilot project
(Instituto Oswaldo Cruz, 2008)
An ecological pilot project for the control of Triatoma dimidiata allowed a new evaluation four and five years
after environmental modifications in the peridomestic areas of 20 households. It was verified that the two ...
Environmental management for the control of Triatoma dimidiata (Latreille, 1811), (Hemiptera: Reduviidae) in Costa Rica: a pilot project
(Memórias do Instituto Oswaldo Cruz, 2006-06)
An ecological control method, using environmental management operations, based on biological and behavioral characteristics of Triatoma dimidiata (Latreille, 1811), was implemented as a pilot project in an area of Costa ...
Evidence of colonization of man-made ecotopes by Triatoma dimidiata (Latreille, 1811) in Costa Rica
(Memórias do Instituto Oswaldo Cruz, 2001-07)
Triatoma dimidiata adults have been frequently found, during the last five years, in a dog kennel and
a chicken coop, in the back yard of a well-built house, 15 km from San José, the capital of Costa Rica.
In the chicken ...
Host life history strategy, species diversity, and habitat influence Trypanosoma cruzi vector infection in changing landscapes
(PLOS Neglected Tropical Diseases, 2012-11-15)
Background: Anthropogenic land use may influence transmission of multi-host vector-borne pathogens by changing
diversity, relative abundance, and community composition of reservoir hosts. These reservoir hosts may have ...

External Morphology of Triatoma rickmani Zeledón & Ponce, 1972 by Scanning Electron Mi croscopy - A male of Triatoma ryckmani Zeledón & Ponce, 1972, was studied by scanning electron
microscopy. Only few specimens of this ...
In vitro activity of thienyl-2-nitropropene compounds against Trypanosoma cruzi
(Memórias do Instituto Oswaldo Cruz, 2009-11)
The in vitro activity of four 2-nitropropene derivatives, 1-(3-benzothienyl)-2-nitropropene (N1), 1-(3-thienyl)-2-
nitropropene (N2), 1-(5-bromo-2-thienyl)-2-nitropropene (N3) and 1-(4-bromo-2-thienyl)-2-nitropropene (N4), ...
Life cycle of Triatoma ryckmani (Hemiptera: Reduviidae) in the laboratory, feeding patterns in nature and experimental infection with Trypanosoma cruzi
(Instituto Oswaldo Cruz, 2010-02)
A cohort initiated with 121 eggs, yielding 105 first instar nymphs (eclosion rate: 86.78%), allowed us to observe
the entire life cycle of Triatoma ryckmani under laboratory conditions (24ºC and 62% relative humidity), ...
Molecular and serological rapid tests as markers of Trypanosoma cruzi infection in dogs in Costa Rica
(Medknow Publications & Media Pvt. Ltd., 2014-07)
Chagas disease is a zoonotic disease caused by Trypanosoma cruzi
and dogs are one of the main domestic reservoirs. Materials and Methods: One
molecular (OligoC‑TesT, Coris Bioconcept) and one serological (T. cruzi‑Detect, ...
