Population Genomics Insights into Adaptive Evolution and Ecological Differentiation in Streptomycetes
(2019)
Deciphering the genomic variation that represents microevolutionary processes toward species divergence is key to understanding microbial speciation, which has long been under debate. Streptomycetes are filamentous bacteria ...
Phylogenetic analyses of antibiotic-producing Streptomyces sp. isolates obtained from the stingless-bee Tetragonisca angustula (Apidae: Meliponini)
(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 ...
Avances de la bioinformática en Costa Rica: Vista retrospectiva y perspectivas
Bioinformatics advances in Costa Rica: Retrospective view and perspectives
(2021-11-09)
Introducción: La disciplina científica de la bioinformática tiene el potencial de generar aplicaciones innovadoras para las sociedades humanas. Costa Rica, pequeña en tamaño y población en comparación con otros países de ...
Biochemical characterization of the venom of Central American scorpion Didymocentrus krausi Francke, 1978 (Diplocentridae) and its toxic effects in vivo and in vitro
(2019)
non-buthid venoms, for which knowledge is scarce. In this work, we characterized the venom of a Diplocentridae
species, Didymocentrus krausi, a small fossorial scorpion that inhabits the Tropical Dry Forest of Central ...
Venomics of the scorpion Tityus ocelote (Scorpiones, Buthidae): Understanding venom evolution in the subgenus Archaeotityus
(2022)
The subgenus Tityus (Archaeotityus) includes small variegated species considered until recently, a basal group within Tityus, one of the most diverse and medically relevant genera of scorpions in the New World. Archaeotityus ...
Welcome to the Atta world: A framework for understanding the effects of leaf‐cutter ants on ecosystem functions
(2019)
1. Leaf‐cutter ants are a prominent feature in Neotropical ecosystems, but a comprehensive assessment of their effects on ecosystem functions is lacking. We reviewed the literature and used our own recent findings to ...
DNase activity in Costa Rican crotaline snake venoms: quantification of activity and identification of electrophoretic variants.
(1991)
DNase activity of Costa Rican crotaline snake venoms from the genera Bothrops, Crotalus and Lachesis was quantified by an enzymodiffusion method on agarose/DNA gels containing ethidium bromide. The reaction is detected as ...
Snake venomics and antivenomics: Proteomic tools in the design and control of antivenoms for the treatment of snakebite envenoming
(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 ...
Proteomic profile of the venom of three dark-colored Tityus (Scorpiones: Buthidae) from the tropical rainforests of Costa Rica
(2023)
Objective: We aimed to elucidate the potential differences in the venom peptide sequences of three Tityus species
from Costa Rican rainforests: T. jaimei, T. championi and T. dedoslargos, compared to T. cf. asthenes ...
