A survey on Triatoma dimidiata in an urban area of the province of Heredia, Costa Rica
(Mem Inst Oswaldo Cruz, 2005-10)Triatoma dimidiata has been found in several cities and towns of those countries where the insect is a domestic or peridomestic pest. In Central America, urban infestations occur in the capitals of at least five ... -
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 ... -
Distribution and ecological aspects of Rhodnius pallescens in Costa Rica and Nicaragua and their epidemiological implications
(Instituto Oswaldo Cruz, 2006)In light of the Central American Initiative for the control of Chagas disease, efforts were made on the part of Costa Rican and Nicaraguan teams, working separately, to determine the present status of Rhodnius pallescens ... -
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 ... -
Ecological patterns of blood-feeding by kissing-bugs (Hemiptera: Reduviidae: Triatominae)
(Instituto Oswaldo Cruz, 2011-06)Host use by vectors is important in understanding the transmission of zoonotic diseases, which can affect hu mans, wildlife and domestic animals. Here, a synthesis of host exploitation patterns by kissing-bugs, vectors of ... -
Entomological and Ecological Aspects of Six Sylvatic Species of Triatomines (Hemiptera, Reduviidae) from the Collection of the National Biodiversity Institute of Costa Rica, Central America
(Memórias do Instituto Oswaldo Cruz, 2001)A total of 797 specimens of wild adult triatomines, belonging to six species from the entomological collections of the Costa Rican National Biodiversity Institute, was studied from the standpoint of their relative ... -
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 ... -
Epidemiological, social, and control determinants of Chagas disease in Central America and Mexico - Group discussion
(Memórias do Instituto Oswaldo Cruz, 2007)The existence of Chagas disease in Central America was reported for the first time in El Salvador in 1913, four years after its discovery in Brazil. At that time only Triatoma dimidiata was known as a vector, but two ... -
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 ... -
Histopathological findings of infections caused by canine distemper virus, Trypanosoma cruzi, and other parasites in two free-ranging White-nosed Coatis Nasua narica (Carnivora: Procyonidae) from Costa Rica
(Zoo Outreach Organisation, 2021-01-26)Canine distemper virus (CDV) causes systemic infections and immunosuppression in carnivores, which subsequently makes animals highly susceptible to opportunistic infections. Although Trypanosoma cruzi infects procyonids, ... -
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 ... -
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), ... -
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, ... -
Molecular characterization of Trypanosoma cruzi and infection rate of the vector Triatoma dimidiate in Costa Rica
(Universidad Nacional, Costa Rica, 2012-06-30)According to the genetic characterization by the analysis of the miniexon gene, strains of Trypanosoma cruzi can be classified into six discrete typing units (DTUs), and the DTU 1 into four distinct genotypes associated ... -
Molecular evidence of intraspecific variability in different habitat-related populations of Triatoma dimidiata (Hemiptera: Reduviidae) from Costa Rica
(Springer, 2010-02-18)Intraspecific genetic variation among Triatoma dimidiata (Hemiptera: Reduviidae) from seven Costa Rican populations and from different domestic, peridomestic, and sylvatic ecotopes were analyzed. The complete ... -
