Antimicrobial activity of myotoxic phospholipases A2 from crotalid snake venoms and synthetic peptide variants derived from their C-terminal region
(Elsevier, 2005)A short peptide derived from the C-terminal region of Bothrops asper myotoxin II, a Lys49 phospholipase A2 (PLA2), was previously found to reproduce the bactericidal activity of its parent molecule. In this study, a panel ... -
Antimicrobial activity of the heliangolide chromolaenide and related sesquiterpene lactones
(Pergamon Press, 1980)Some sesquiterpene lactones are known to exhibit antimicrobial activity [1, 2]. More recently, it has been noted that the pseudoguainolide carpesiolin inhibits the growth of Xanthomonas oryzae [3]. Here, we report on ... -
Antimicrobial resistance genes in pigeons from public parks in Costa Rica
(Blackwell Verlag GmbH, 2017)Antimicrobial resistance is known to be an emerging problem, but the extent of the issue remains incomplete. The aim of this study was to determine the pres- ence or absence of nine resistance genes (blaTEM, catI, mecA, ... -

Backyard Chicken Flocks Pose a Disease Risk for Neotropic Birds in Costa Rica
(American Association of Avian Pathologists, 2008)Pathogens of free-ranging chickens create a risk of disease for wild birds, some of which migrate to the United States, as well as potential economic losses for resource-poor farmers. Free-roaming backyard chickens are ... -
Caracterización fenotípica y molecular de aislamientos multirresistentes de Staphylococcus aureus en el Laboratorio de Bacteriología de la Escuela de Medicina Veterinaria, Universidad Nacional
(Universidad Nacional, Costa Rica, 2022)Staphylococcus aureus es una bacteria oportunista que puede causar infecciones en animales y seres humanos cuando las barreras cutáneas y mucosas se rompen. Estas infecciones se han convertido en una amenaza para la salud ... -
Determinación de los perfiles de susceptibilidad a antibióticos y genes blaCMY-2 y blaCTX-M en bacterias del género Salmonella aisladas de tres matrices de la cadena de producción avícola de Costa Rica
(Universidad Nacional, Costa Rica, 2022)El objetivo de esta investigación fue determinar la susceptibilidad a 20 antibióticos y la presencia de genes de resistencia a betalactámicos, específicamente blaCMY-2 y blaCTX-M en aislamientos de Salmonella enterica ... -
Determination of streptomycin and doxycycline using LC/MS towards an effective treatment against an experimental Brucella abortus infection in mice
(Elsevier B.V, 2022-02-25)Herein we described a versatile liquid chromatographic method for detection and quantification of the total levels of two antimicrobials [i.e., streptomycin (STM) and doxycycline (DOX)], in mice plasma and selected tissues, ... -
Estimación de la prevalencia, susceptibilidad antimicrobiana y serotipificación de Salmonella enterica recuperada de primates no humanos de nuevo mundo, de alimentos y de superficies en centros de cautiverio de animales silvestres en Costa Rica
(Universidad Nacional, Costa Rica, 2022)La preocupación por las zoonosis y la vida silvestre ha aumentado debido al creciente acercamiento entre la vida silvestre y los humanos como resultado de la expansión humana, la globalización, el cambio climático y las ... -
First report of a Multidrug-Resistant ST58 Escherichia coli Harboring Extended-Spectrum Beta-Lactamase of the CTX-M-1 Class in a Fecal Sample of a Captive Baird’s Tapir (Tapirus bairdii) in Costa Rica, Central America
(Mary Ann Liebert, 2022-01)Objective: This study’s main objective was to analyze the antibiotic susceptibility profile of Escherichia coli isolates obtained from a fecal sample of a captive Baird’s tapir (Tapirus bairdii) in Costa Rica. Materials ... -
High prevalence of multidrug-resistant community-acquired methicillin-resistant staphylococcus aureus at the largest veterinary teaching hospital in Costa Rica
(Mary Ann Liebert, Inc., 2017)Methicillin-resistant Staphylococcus aureus (MRSA) is a pathogen associated with severe infections in companion animals present in the community, and it is diagnosed in animals admitted to veterinary hospitals. However, ... -
