      Campos, Ricardo; Botto Mahan, Carezza; Ortiz, Sylvia; Coronado, Ximena; Solari Illescas, Aldo (AMER SOC TROP MED & HYGIENE, 2010-04-19)
      We identified and followed-up for two years Octodon degus rodents infected with Trypanosoma cruzi genotypes by using xenodiagnosis with two vector species ( Mepraia spinolai and Triatoma infestans ), polymerase chain ...
    • Short report: Trypanosoma cruzi infection in wild mammals from a chagasic area of Chile 
      Rozas, Marlene; Botto Mahan, Carezza; Coronado, Ximena; Ortiz Zúñiga, Sylvia; Cattan Ayala, Pedro; Solari Illescas, Aldo (AMER SOC TROP MED & HYGIENE, 2005-09)
      We report results of PCR-DNA based detection of Trypanosoma cruzi in wild mammal reservoirs from a chagasic area of Chile. We analyzed 157 blood samples from wild mammals including the marsupial Thylamis elegans and the ...
    • Spatial distribution of an infectious disease in a small mammal community 
      Correa, Juana P.; Bacigalupo, Antonella; Fontúrbel, Francisco E.; Oda, Esteban; Cattan Ayala, Pedro; Solari Illescas, Aldo; Botto Mahan, Carezza (Springer, 2015)
      Chagas disease is a zoonosis caused by the parasite Trypanosoma cruzi and transmitted by insect vectors to several mammals, but little is known about its spatial epidemiology. We assessed the spatial distribution of T. ...
    • Stridulation in the wild kissing bug Mepraia spinolai: description of the stridulatory organ and vibratory ... 
      Quiroga Hidalgo, Nicol; Muñoz, Matías I.; Pérez Espinoza, Samuel; Penna, Mario; Botto Mahan, Carezza (Taylor & Francis, 2020)
      Stridulation is a type of communication in which a mechanical signal is emitted by the friction of two rigid structures. Stridulation is present in kissing bugs (Reduviidae: Triatominae), where the friction of the proboscis ...
    • Susceptibility of Mepraia spinolai and Triatoma infestans to different Trypanosoma cruzi strains from ... 
      Campos, Ricardo; Acuña Retamar, Mariana; Botto Mahan, Carezza; Ortiz Zúñiga, Sylvia; Cattan Ayala, Pedro; Solari Illescas, Aldo (ELSEVIER, 2007)
      Trypanosoma cruzi is the causative agent of Chagas disease, a zoonosis involving domestic and sylvatic mammalian reservoirs. Since scarce information has been published about the susceptibility of T. cruzi lineages to ...
    • Temporal fluctuation in shrub species preferences of two native rodents: The effect of infection status on ... 
      Donoso, M. Isabel; Fonturbel, Francisco E.; Cares, Rocio A.; Oda, Esteban; Ramírez, Patricia A.; Botto Mahan, Carezza (Wiley-Blackwell, 2016)
      Small mammals use plant species for gathering food resources and for shelter. Preferences for certain plant species are related to nutritional restrictions and behavioural patterns, which could be altered in the presence ...
    • Temporal variation in Trypanosoma cruzi lineages from the native rodent Octodon degus in semiarid Chile 
      Botto Mahan, Carezza; Rojo, Gemma; Sandoval Rodríguez, Alejandra; Peña, Fabiola; Ortiz, Sylvia; Solari Illescas, Aldo (Elsevier, 2015)
      Chagas disease is a zoonosis caused by the protozoan parasite Trypanosome cruzi and transmitted by triatomine insects to several mammalian species acting as reservoir hosts. In the present study, we assess T. cruzi-prevalence ...
    • Temporal Variation of Trypanosoma cruzi Infection in Native Mammals in Chile 
      Botto Mahan, Carezza; Campos, Ricardo; Acuña Retamar, Mariana; Coronado, Ximena; Cattan Ayala, Pedro; Solari Illescas, Aldo (2010)
      In the present study, we compared Trypanosoma cruzi infection in four native mammals from a hyperendemic area of Chagas disease in Chile for two different periods to assess the occurrence of interannual variation (1999– 2000 ...
    • TRYPANOSOMA CRUZI DETECTION IN BLOOD BY XENODIAGNOSIS AND POLYMERASE CHAIN REACTION IN THE WILD RODENT ... 
      Campos, Ricardo; Botto Mahan, Carezza; Ortiz Zúñiga, Sylvia; Acuña Retamar, Mariana; Cattan Ayala, Pedro; Solari Illescas, Aldo (2007)
      We detected Trypanosoma cruzi in blood samples of the wild rodent Octodon degus by xenodiagnosis and a polymerase chain reaction (PCR) using the domestic and wild vectors of Chagas disease, Triatoma infestans and Mepraia ...
    • Trypanosoma cruzi infection in the sylvatic kissing bug Mepraia gajardoi from the Chilean Southern Pacific ... 
      Botto Mahan, Carezza; Sepúlveda, Maritza; Vidal, Marcela A.; Acuña Retamar, Mariana; Ortiz Zúñiga, Sylvia; Solari Illescas, Aldo (ELSEVIER, 2008-02)
      The Southern Pacific Ocean coast has been traditionally considered a non-active transmission area for Chagas disease. In this report, we show evidence of Trypanosoma cruzi infection in the sylvatic kissing bug Mepraia ...
    • Trypanosoma cruzi infection in wild mammals from a chagasic area of Chile 
      Rozas, Marlene; Botto Mahan, Carezza; Coronado, Ximena; Ortiz Zúñiga, Sylvia; Cattan Ayala, Pedro; Solari Illescas, Aldo (AMER SOC TROP MED & HYGIENE, 2005-09)
      We report results of PCR-DNA based detection of Trypanosoma cruzi in wild mammal reservoirs from a chagasic area of Chile. We analyzed 157 blood samples from wild mammals including the marsupial Thylamis elegans and the ...
    • What does determine gonad weight in the wild kissing bug Mepraia spinolai? 
      Botto Mahan, Carezza; Medel Contreras, Rodrigo (2007)
      Female fecundity increases with body size in a variety of insects, but it is unknown if this generalization applies for kissing bugs. In this study, we evaluate whether gonad weight in, the bloodsucking insect Mepraia ...
