    • Bocaparvovirus, Erythroparvovirus and Tetraparvovirus in New World Primates from Central America 

      Chaves Ramírez, Andrea; Ibarra Cerdeña, Carlos N.; López Pérez, Andrés; Monge Solano, Otto; Avendaño Vega, Roberto; Ureña Saborío, Hilary; Chavarría Vargas, Max; Zaldaña, Karla; Sánchez, Lucía; Ortíz Malavasi, Edgar; Suzán, Gerardo; Foley, Janet; Gutiérrez Espeleta, Gustavo A. (2020)
      Parvoviruses in the genera Bocaparvovirus (HBoV), Erythroparvovirus (B19) and Tetraparvovirus (PARV4) are the only autonomous parvoviruses known to be associated with human and non‐human primates based on studies and ...

    • Fungi with history: Unveiling the mycobiota of historic documents of Costa Rica 

      Escudero Leyva, Efraín; Vieto Fonseca, Sofía; Avendaño Vega, Roberto; Rojas Gätjens, Diego; Agüero Gamboa, Paola; Pacheco Ureña, Carlos; Montero Villalobos, Mavis Lili; Chaverri Echandi, Priscila; Chavarría Vargas, Max (2022-06-12)
      Through nondestructive techniques, we studied the physicochemical characteristics and mycobiota of five key historic documents from Costa Rica, including the Independence Act of Costa Rica from 1821. We determined that for ...

    • Methylotrophs and Hydrocarbon-Degrading Bacteria Are Key Players in the Microbial Community of an Abandoned Century-Old Oil Exploration Well 

      Rojas Gätjens, Diego; Fuentes Schweizer, Paola; Rojas Jiménez, Keilor Osvaldo; Pérez Pantoja, Danilo; Avendaño Vega, Roberto; Alpízar Mena, Randall; Coronado Ruiz, Carolina; Chavarría Vargas, Max (2021-04-17)
      In this work, we studied the microbial community and the physicochemical conditions prevailing in an exploratory oil well, abandoned a century ago, located in the Cahuita National Park (Costa Rica). According to our analysis, ...

    • Microbial Community Structure Alogn a Horizontal Oxygen Gradient in a Costa Rican Volcanic Influeced Acid Rock Drainage System 

      Arce Rodríguez, Alejandro; Puente Sánchez, Fernando; Avendaño Vega, Roberto; Libby Hernández, Eduardo; Mora Amador, Raúl Alberto; Rojas Jiménez, Keilor; Martínez Cruz, María; Pieper, Dietmar H.; Chavarría Vargas, Max (2020-06-22)
      We describe the geochemistry and microbial diversity of a pristine environment that resembles an acid rock drainage (ARD) but it is actually the result of hydrothermal and volcanic influences. We designate this environment, ...

    • Pristine but metal-rich Río Sucio (Dirty River) is dominated by Gallionella and other iron-sulfur oxidizing microbes 

      Arce Rodríguez, Alejandro; Puente Sánchez, Fernando; Avendaño Vega, Roberto; Libby Hernández, Eduardo; Rojas Sánchez, Leonardo; Cambronero Heinrichs, Juan Carlos; Pieper, Dietmar H.; Timmis, Kenneth N.; Chavarría Vargas, Max (2017-03)
      Whether the extreme conditions of acidity and heavy metal pollution of streams and rivers originating in pyritic formations are caused primarily by mining activities or by natural activities of metal-oxidizing microbes ...

    • Rapid shift in microbial community structure in a neutral hydrothermal hot spring from Costa Rica 

      Rojas Gätjens, Diego; Arce Rodríguez, Alejandro; Puente Sánchez, Fernando; Avendaño Vega, Roberto; Libby Hernández, Eduardo; Conejo Barboza, Geraldine; Mora Amador, Raúl Alberto; Rojas Jiménez, Keilor Osvaldo; Pieper, Dietmar H.; Chavarría Vargas, Max (2020)
      In this work, we characterize the geochemistry and microbial community of Bajo las Peñas, a neutral (pH 6.5-7.4), hot spring (T = 62.0-68.0°C) located near Turrialba Volcano, Costa Rica. The microbiota at its two sources ...
