    • 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, ...
    • 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 ...
    • Renal carriage of Leptospira species in rodents from Mediterranean Chile: The Norway rat (Rattus norvegicus) ... 
      Correa, Juana P.; Bucarey Vivanco, Sergio; Cattan Ayala, Pedro; Landaeta Aqueveque, Carlos; Ramírez Estrada, Juan (Elsevier, 2017)
      We evaluated the renal carriage of Leptospira species in rodent communities from Mediterranean Chile using a PCR technique. We found that animals inhabiting agricultural areas were almost three times more infected than in ...
    • Spatio-temporal characterization of Trypanosoma cruzi infection and discrete typing units infecting hosts ... 
      Ihle Soto, Camila Adriana; Costoya, Eduardo; Correa, Juana P.; Bacigalupo, Antonella; Cornejo-Villar, Berenice; Estadella, Viviana; Solari, Aldo; Ortiz, Sylvia; Hernández, Héctor J.; Botto Mahan, Carezza; Gorla, David E.; Cattan Ayala, Pedro (Public Library of Science, 2019)
      Background Trypanosoma cruzi is a protozoan parasite that is transmitted by triatomine vectors to mammals. It is classified in six discrete typing units (DTUs). In Chile, domestic vectorial transmission has been interrupted; ...
    • 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 ...
    • Within-host temporal fluctuations of trypanosoma cruzi discrete typing units: the case of the wild reservoir ... 
      Rojo, Gemma; Sandoval Rodríguez, Alejandra; López, Angélica; Ortiz Zuñiga, Sylvia; Correa, Juana P.; Saavedra, Miguel; Botto Mahan, Carezza; Cattan Ayala, Pedro; Solari Illescas, Aldo (BIOMED Central Ltd., 2017)
      Background: Chagas disease caused by Trypanosoma cruzi is considered a major public health problem in America. After an acute phase the disease changes to a chronic phase with very low parasitemia. The parasite presents ...
