Abundance, Natural Infection with Trypanosomes, and Food Source of an Endemic Species of Triatomine, Panstrongylus howardi (Neiva 1911), on the Ecuadorian Central Coast

Baus Carrera, Esteban Guillermo; Grijalva Cobo, Mario Javier; Ocaña Mayorga, Sofía Beatriz; Villacis Salazar, Anita Gabriela; Yumiseva Marín, César Alberto (2015)

The elimination of domestic triatomines is the foundation of Chagas disease control. Regional initiatives are eliminating introduced triatomine species. In this scenario, endemic triatomines can occupy the ecological niches ...
Bats, trypanosomes, and triatomines in Ecuador: new insights into the diversity, transmission, and origins of Trypanosoma cruzi and chagas disease

Grijalva Cobo, Mario Javier; Ocaña Mayorga, Sofía Beatriz; Pinto Báez, Christian Miguel; Villacis Salazar, Anita Gabriela (14/10/2015)

The generalist parasite Trypanosoma cruzi has two phylogenetic lineages associated almost exclusively with bats—Trypanosoma cruzi Tcbat and the subspecies T. c. marinkellei. We present new information on the genetic ...
Chagas vectors Panstrongylus chinai (Del Ponte, 1929) and Panstrongylus howardi (Neiva, 1911): chromatic forms or true species?

Villacis Salazar, Anita Gabriela; Yumiseva Marín, César Alberto (2020-05-06)

Background: Chagas disease is a parasitic infection transmitted by “kissing bugs” (Hemiptera: Reduviidae: Triatominae) that has a huge economic impact in Latin American countries. The vector species with the upmost ...
Determinants of intentions to prevent triatomine infestation based on the health belief model: An application in rural southern Ecuador

Villacis Salazar, Anita Gabriela (2020)

Introduction: Control of triatomine infestation is a key strategy for the prevention of Chagas disease (CD). To promote this strategy, it is important to know which antecedents to behavioral change are the best to emphasize ...
Diseño y desarrollo de un videojuego Educativo mediante una metodología ágil, como herramienta orientada a niños de 7 a 11 años para la prevención de la enfermedad de Chagas

Rodríguez Clavijo, Francisco; Villacis Salazar, Anita Gabriela (2020)

Chagas disease (CD) is caused by Trypanosoma cruzi and transmitted by the feces of Triatomine insects. The absence of treatments and effective vaccines makes this disease not only a medical problem, but also an educational, ...
Distribution of triatomine species in domestic and peridomestic environments in central coastal Ecuador

Baus Carrera, Esteban Guillermo; Grijalva Cobo, Mario Javier; Moncayo Benalcázar, Ana Lucía; Ocaña Mayorga, Sofía Beatriz; Villacis Salazar, Anita Gabriela; Yumiseva Marín, César Alberto (2017)

Background: Although the central coast of the Ecuador is considered endemic for Chagas disease, few studies have focused on determining the risk of transmission in this region. In this study we describe the triatomine ...
Genetic data support speciation between Panstrongylus howardi and Panstrongylus chinai, vectors of Chagas disease in Ecuador

Villacis Salazar, Anita Gabriela; Yumiseva Marín, César Alberto (2020-03)

Limited genetic data are currently available for three vectors of Chagas disease in Ecuador, Panstrongylus howardi, P. chinai, and P. rufotuberculatus. Previously regarded as mainly sylvatic, these species have been poorly ...
Influence of ecological factors on the presence of a triatomine species associated with the arboreal habitat of a host of Trypanosoma cruzi

Crespo Pérez, María Verónica; Grijalva Cobo, Mario Javier; Ocaña Mayorga, Sofía Beatriz; Pinto Báez, Christian Miguel; Villacis Salazar, Anita Gabriela (2018)

Background: The white-naped squirrel, Simosciurus nebouxii (previously known as Sciurus stramineus), has recently been identified as an important natural host for Trypanosoma cruzi in Ecuador. The nests of this species ...
Life cycle, feeding, and defecation patterns of Panstrongylus chinai (Hemiptera: Reduviidae: Triatominae) under laboratory conditions

Villacis Salazar, Anita Gabriela; Grijalva Cobo, Mario Javier (2016-07)

Chagas disease is caused by the protozoan Trypanosoma cruzi. Panstrongylus chinai (Del Ponte) is highly domiciliated in the Peruvian and Ecuadorian Andes and has been found naturally infected with T. cruzi. The objective ...
Life cycle, feeding, and defecation patterns of Triatoma carrioni (Hemiptera: Reduviidae), under laboratory conditions

Grijalva Cobo, Mario Javier; Moncayo Benalcázar, Ana Lucía; Villacis Salazar, Anita Gabriela (2019-04)

Chagas disease is caused by Trypanosoma cruzi (Kinetoplastida: Trypanosomatidae). It is transmitted to humans primarily through contaminated feces of blood-sucking vectors of the subfamily Triatominae, known in Ecuador as ...
Molecular data supports monophyly of Triatoma dispar complex within genus Triatoma

Villacis Salazar, Anita Gabriela; Yumiseva Marín, César Alberto (2020-11)

The genus Triatoma contains numerous species, principal or secondary vectors of Chagas disease, which have been included in the three main lineages of Triatomini tribe based on morphological and biogeographical characteristics: ...
Pioneer study of population genetics of Rhodnius ecuadoriensis (Hemiptera: Reduviidae) from the central coastand southern Andean regions of Ecuador

Grijalva Cobo, Mario Javier; Villacis Salazar, Anita Gabriela; Yumiseva Marín, César Alberto (2017-09)

Effective control of Chagas disease vector populations requires a good understanding of the epidemiological components, including a reliable analysis of the genetic structure of vector populations. Rhodnius ecuadoriensis ...
Triatominae: does the shape change of non-viable eggs compromise species recognition?

Grijalva Cobo, Mario Javier; Villacis Salazar, Anita Gabriela (2018-10-10)

Eggs have epidemiological and taxonomic importance in the subfamily Triatominae, which contains Chagas disease vectors. The metric properties (size and shape) of eggs are useful for distinguishing between close species, ...
Trypanosoma cruzi population dynamics in the Central Ecuadorian Coast.

Costales Cordero, Jaime Alfredo; Grijalva Cobo, Mario Javier; Villacis Salazar, Anita Gabriela; Ocaña Mayorga, Sofía Beatriz (2015)

tChagas disease is the most important parasitic disease in Latin America. The causative agent, Trypanosomacruzi, displays high genetic diversity and circulates in complex transmission cycles among domestic,peridomestic and ...
Vector transmission: How it works, what transmits, where it occurs

Villacis Salazar, Anita Gabriela (2017)

Vector transmission remains the main mode of Chagas disease transmission. The first part of this chapter presents the current state of knowledge on the transmission mechanisms, the factors that attract bugs to their prey, ...
Would tropical climatic variations impact the genetic variability of triatomines: Rhodnius ecuadoriensis, principal vector of Chagas disease in Ecuador?

Villacis Salazar, Anita Gabriela; Yumiseva Marín, Cesar Alberto (2009-09)

Rhodnius ecuadoriensis is one of the most important vector species of Chagas disease in Ecuador. This species is distributed in the Central coast region and in the south Andean region, and an incipient speciation process ...
