    • Ant microbial symbionts are a new model for drug discovery 

      Artavia León, Allan; Pacheco Leiva, Miguel; Moya Román, Cristofer; Rodríguez Hernández, Natalia; Pinto Tomás, Adrián A. (2019)
      Ants have been widely studied, with 14,000 described species, but it is not until recently that they gained attention as sources for antimicrobial drug discovery. An increasing amount of studies are investigating ant-microbe ...
    • ‘Candidatus Rickettsia nicoyana’: A novel Rickettsia species isolated from Ornithodoros knoxjonesi in Costa Rica 

      Moreira Soto, Rolando Daniel; Moreira Soto, Andrés; Corrales Aguilar, Eugenia; Calderón Arguedas, Ólger; Troyo Rodríguez, Adriana (2017-06)
      Rickettsiae are intracellular bacteria commonly associated with hematophagous arthropods. Most of them have been described in hard ticks, but some have been found in soft ticks. Here we report the detection and isolation ...
    • Community richness of amphibian skin bacteria correlates with bioclimate at the global scale 

      Kueneman, Jordan G.; Bletz, Molly C.; McKenzie, Valerie J.; Becker, C.

      Animal-associated microbiomes are integral to host health, yet key biotic and abiotic factors that shape host-associated microbial communities at the global scale remain poorly understood. We investigated global patterns ...
    • Ectoparasites of dogs in home environments on the Caribbean slope of Costa Rica 

      Troyo Rodríguez, Adriana; Calderón Arguedas, Ólger; Alvarado Barboza, Gilberth; Vargas Castro, Luis E.; Avendaño López, Adrián (2012)
      Reports on ectoparasites on dogs in Central America are scarce. The aim of this study was to identify flea, louse and tick species infesting dogs in home environments on the Caribbean slope of Costa Rica, and determine ...
    • ENSO‐Influenced Drought Drives Methane Flux Dynamics in a Tropical Wet Forest Soil 

      Aronson, Emma L.; Dierick, Diego; Botthoff, J. K.; Oberbauer, Steven F.; Zelikova, Tamara Jane; Harmon, Thomas C.; Rundel, Philip W.; Johnson, Robert F.; Swanson, Amanda C.; Pinto Tomás, Adrián A.; Artavia León, Allan; Matarrita Carranza, Bernal; Allen, Michael F. (2019)
      Global atmospheric methane growth rates have wildly fluctuated over the past three decades, which may be driven by the proportion of tropical land surface saturated by water. The El Niño/Southern Oscillation Event (ENSO) ...
    • Pathogenic potential of a Costa Rican strain of ‘Candidatus Rickettsia amblyommii’ in guinea pigs (Cavia porcellus) and protective immunity against Rickettsia rickettsii 

      Rivas Mejías, Juan José; Moreira Soto, Andrés; Alvarado Barboza, Gilberth; Taylor Castillo, Mayra Lizeth; Calderón Arguedas, Ólger; Hun Opfer, Ruchilia Laya; Corrales Aguilar, Eugenia; Morales Acuña, Juan Alberto; Troyo Rodríguez, Adriana (2015-07)
      ‘Candidatus Rickettsia amblyommii’ is a spotted fever group rickettsia that is not considered pathogenic, although there is serologic evidence of possible infection in animals and humans. The aim of this study was to ...
    • Phylogenetic analyses of antibiotic-producing Streptomyces sp. isolates obtained from the stingless-bee Tetragonisca angustula (Apidae: Meliponini) 

      Cambronero Heinrichs, Juan Carlos; Matarrita Carranza, Bernal; Murillo Cruz, Catalina; Araya Valverde, Emanuel; Chavarría Vargas, Max; Pinto Tomás, Adrián A. (2019)
      Many insects have been associated with actinobacteria in protective symbiosis where antimicrobial metabolites inhibit host pathogens. However, the microbiota of neotropical insects such as the stingless-bee Tetragonisca ...
    • Snake venomics and antivenomics: Proteomic tools in the design and control of antivenoms for the treatment of snakebite envenoming 

      Gutiérrez, José María; Lomonte, Bruno; León Montero, Guillermo; Alape Girón, Alberto; Flores Díaz, Marietta; Sanz, Libia; Angulo Ugalde, Yamileth; Calvete Chornet, Juan José (2009-03-06)
      Snakebite envenoming represents a neglected tropical disease that has a heavy public health impact, particularly in Asia, Africa and Latin America. A global initiative, aimed at increasing antivenom production and ...
    • The antimicrobial potential of Streptomyces from insect microbiomes 

      Chevrette, Marc G.; Carlson, Caitlin M.; Ortega Dominguez, Humberto Enrique; Thomas, Christopher S.; Ananiev, Gene E.; Barns, Kenneth J.; Book, Adam J.; Cagnazzo, Julian; Carlos Shanley, Camila; Flanigan, Will; Grubbs, Kirk J.; Horn, Heidi A.; Hoffmann, F.
