    • Differential pattern of infection of sylvatic nymphs and domiciliary adults of Triatoma infestans with ... 
      Bacigalupo, Antonella; Segovia, Verónica; García, Alejandro; Botto Mahan, Carezza; Ortíz, Sylvia; Solari Illescas, Aldo; Acuña Retamar, Mariana; Torres Pérez, Fernando; Cattan Ayala, Pedro (2012)
      In Chile, the main vector of Chagas disease, Triatoma infestans, is under control after insecticide spraying. However, it has been found colonizing wild habitats. This study evaluated Trypanosoma cruzi infection of sylvatic ...
    • Field assessment of Trypanosoma cruzi infection and host survival in the native rodent Octodon degus 
      Botto Mahan, Carezza; Bacigalupo, Antonella; Correa, Juana P.; Oda, Esteban; Solari Illescas, Aldo (2012)
      Chagas disease is a zoonosis caused by the flagellated parasite Trypanosoma cruzi and transmitted by triatomine insects to several mammalian species acting as reservoir hosts. In the present study, we assess T. cruzi-prevalence, ...
    • Modeling the spatial distribution of Chagas disease vectors using environmental variables and peoplés knowledge 
      Hernández, Jaime; Núñez, Ignacia; Bacigalupo, Antonella; Cattan Ayala, Pedro (2013)
      Background: Chagas disease is caused by the protozoan Trypanosoma cruzi, which is transmitted to mammal hosts by triatomine insect vectors. The goal of this study was to model the spatial distribution of triatomine species ...
    • Modelo predictivo de la distribución de triatominos a escala local 
      Bacigalupo, Antonella (Universidad de Chile, 2016)
      El objetivo de este estudio fue determinar un modelo predictivo de distribución de focos de triatominos a escala local en zonas rurales del área endémica de Chile. Se realizó un muestreo sistemático por conglomerados ...
    • Natural infection of leptospira species in the native rodents degu (Octodon degus) and Darwin's Pericote ... 
      Correa, Juana P.; Bacigalupo, Antonella; Botto Mahan, Carezza; Bucarey Vivanco, Sergio; Cattan Ayala, Pedro; García de Cortázar, Rodrigo; Landaeta Aqueveque, Carlos; Ramírez Estrada, Juan (Wildlife Disease Assoc, Inc., 2017)
      We report natural infections by pathogenic Leptospira of two rodent species endemic to Chile: the degu (Octodon degus) and Darwin's pericote (Phyllotis darwini). We detected Leptospira DNA in kidney and urine samples taken ...
    • Organs infected with Trypanosoma cruzi and DTU identification in the naturally infected rodent Octodon degus 
      Rojo Aravena, Gemma Beatriz; Pelissier Serrano, Teresa; Sandoval Rodríguez, Alejandra; Bacigalupo, Antonella; García, Vanessa; Pinto Sierralta, Raquel; Ortiz, Sylvia; Botto Mahan, Carezza; Cattan Ayala, Pedro; Solari Illescas, Aldo (Elsevier, 2020)
      Chagas disease is a public health problem in America. Its parasite, Trypanosoma cruzi, presents different discrete typing units (DTUs), colonizes organs of mammalian hosts in chronic infections, and presents tropism for ...
    • Prevalence, infected density or individual probability of infection? Assessing vector infection risk in the ... 
      Botto Mahan, Carezza; Bacigalupo Bacigalupo, Antonella; Correa Galaz, Juana; Fonturbel, Francisco E.; Cattan Ayala, Pedro; (The Royal Society, 2020)
      Vector-borne infectious disease dynamics result mainly from the intertwined effect of the diversity, abundance, and behaviour of hosts and vectors. Most studies, however, have analysed the relationship between host-species ...
    • Spatial quantification of the world population potentially exposed to Zika virus 
      Alaniz, Alberto J.; Bacigalupo, Antonella; Cattan Ayala, Pedro (Oxford Universitu Press, 2017)
      Background: Zika virus is an emerging Flaviviridae virus, which has spread rapidly in the last few years. It has raised concern because it has been associated with fetus microcephaly when pregnant women are infected. The ...
    • Sylvatic foci of the Chagas disease vector Triatoma infestans in Chile: Description of a new focus and ... 
      Bacigalupo, Antonella; Torres Pérez, Fernando; Segovia, Verónica; García, Alejandro; Correa, Juana P.; Moreno, Lucila; Arroyo, Patricio; Cattan Ayala, Pedro (Fundacao Oswaldo Cruz, 2010)
      Triatoma infestans is one of the main domestic vectors of Chagas disease. Reports of wild habitat occurrences have recently increased. In Chile, after a successful elimination campaign of T. infestans domestic infestation, ...
    • Trypanosoma cruzi load in synanthropic rodents from rural areas in Chile 
      Yefi Quinteros, Esteban; Muñoz San Martín, Catalina; Bacigalupo, Antonella; Correa, Juana P.; Cattan Ayala, Pedro (BIOMED Central Ltd., 2018)
      Background: Trypanosoma cruzi is the agent of Chagas disease, a major public health problem in Latin America. Many wild and domestic animals are naturally infected with T. cruzi; rodents are one of the groups which have ...
    • Zika: probabilidad de establecimiento de su vector, Aedes aegypti, en Chile 
      Alaniz, Alberto J.; Bacigalupo, Antonella; Cattan Ayala, Pedro (Sociedad Chilena de Infectología, 2017)
      The Zika virus has raised world alarm in recent years, representing a major public health problem. In this study we evaluated the potential risk of exposure to Zika virus in Chile, associated with the probability of ...
