Bacteriological quality and beach bitter at five coastal marine environments of Costa Rica
(2006-09-01)
Anthropogenic waste and water bacteriological quality were surveyed twice a year in 2000 and in 2002 at five
coastal marine environments in Costa Rica, one in the Caribbean (Moín Bay) and four in the Pacific (Culebra ...
Mapping the risk of Aedes aegypti larval habitats using tree cover in Puntarenas, Costa Rica
(2010-08)
Tree cover and other characteristics of urban structure have been associated in urban environments with abundance and productivity of Aedes aegypti and other mosquito larval habitats. Tree cover can conceal containers, ...

Presence and potential distribution of malaria‑infected New World primates of Costa Rica
(2022-01-08)
Background: In South and Central America, Plasmodium malariae/Plasmodium brasilianum, Plasmodium vivax, Plas- modium simium, and Plasmodium falciparum has been reported in New World primates (NWP). Specifically in Costa ...
Presencia de Trypanosoma minasense (Kinetoplastida: Trypanosomatidae) en Alouatta palliata (Primates: Cebidae) de Costa Rica
Trypanosoma minasense (Kinetoplastida: Trypanosomatidae) in Alouatta palliata (Primates: Cebidae) of Costa Rica
(2005)
A Trypanosoma from the howler monkey Alouatta palliata was studied. Measures, as well as its biological characteristics (mice infection and failure to infect Triatominae) identify this parasite as Trypanosoma minasense. ...
Venom characterization of the bark scorpion Centruroides edwardsii (Gervais 1843): composition, biochemical activities and in vivo toxicity for potential prey
(2019)
In this study, we characterize the venom of Centruroides edwardsii, one of the most abundant scorpions in urban

Mechanisms of low susceptibility to the disinfectant benzalkonium chloride in a multidrug-resistant environmental isolate of Aeromonas hydrophila
(2023)
Excessive discharge of quaternary ammonium disinfectants such as benzalkonium chloride (BAC) into aquatic systems can trigger several physiological responses in environmental microorganisms. In this study, we isolated a ...
Identification of New Snake Venom Metalloproteinase Inhibitors Using Compound Screening and Rational Peptide Design
(2012)
The majority of snakebite envenomations in Central America are caused by the viperid species Bothrops asper, whose venom contains a high proportion of zinc-dependent metalloproteinases that play a relevant role in the ...
