R-Ras Glucosylation and transient RhoA activation determine the cytopathic effect produced by Toxin B variants from Toxin A-negative strains of clostridium difficile
(American Society for Biochemistry and Molecular Biology, 2003-03-07)
Clostridium difficile induces antibiotic-associated diarrhea through the production of toxin A and toxin B;
the former toxin has been assumed to be responsible for the symptoms of the disease. Several toxin A-negative ...
Multidrug-Resistant CTX-M and CMY-2 producing Escherichia coli Isolated from healthy household dogs from the great metropolitan area, Costa Rica
(Mary Ann Liebert, Inc., 2020)
Objective:This study aimed to determine the prevalence of fecal carriage of antibiotic-resistantEscherichia coliof healthy household dogs with an emphasis on extended-spectrumb-lactamases (ESBL), AmpC-typeb-lactamases ...
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, ...
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, ...
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 ...
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 ...
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 ...
Prevalence, resistance patterns, and risk factors for antimicrobial resistance in bacteria from retail chicken meat in Colombia
(International Association for Food Protection, 2015)
As a step toward implementing the Colombian Integrated Program for Antimicrobial Resistance Surveillance (COIPARS),
this study aimed to establish the baseline antimicrobial resistance patterns of Salmonella serovars, ...
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 ...
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 ...
