Data on enteric yersinioses in Central America are limited. Genomic characterization of 78 Yersinia enterocolitica isolates from Costa Rica indicated persistent infection-source circulation between animal reservoirs and humans, as well unusual antimicrobial resistance levels. Our study highlights the importance genomic surveillance to monitor Yersinia-caused infections Rica.
Brucella abortus is a facultative intracellular pathogen causing severe zoonotic disease worldwide. The two-component regulatory system (TCS) BvrR/BvrS of B . conserved in members the Alphaproteobacteria class. It related to expression genes required for host interaction and survival. Here we report that bvrR bvrS are part an operon composed 16 encoding functions nitrogen metabolism, DNA repair recombination, cell cycle arrest, stress response. Synteny this genomic region within close...
<p class="p1">Biodigesters are designed to optimize biogas production using organic wastes, thereby attaining clean, low-cost renewable energy. In 2008, a group of ITCR researchers worked on developing wireless electronic system for control and protection production. One the specific objectives this work was find information about methods increase review we established mathematical parameters related estimation productivity. We then focused influence chemical factors such as substrate...
Brucella abortus is a bacterial pathogen causing bovine brucellosis worldwide. This facultative extracellular–intracellular can be transmitted to humans, leading zoonotic disease. The disease remains public health concern, particularly in regions where livestock farming present. two-component regulatory system BvrR/BvrS was described by isolating the attenuated transposition mutants bvrR::Tn5 and bvrS::Tn5, whose characterization led understanding of role survival. However, phenotypic...
<p>El encallamiento de cetáceos se presenta cuando estos mamíferos llegan a la playa sin poder regresar al mar por sus propios medios. En Costa Rica, mayoría los casos han registrado en las costas del Pacífico. Entre posibles causas este fenómeno, están enfermedades infecciosas como brucelosis marina. Dicha enfermedad es provocada bacterias género Brucella, y puede transmitir humanos. El contacto entre humanos ha venido aumento debido actividades recreativas ocupacionales. Además, el...
<p class="p1"><em>Brucella abortus </em>es un patógeno intracelular facultativo que pertenece a la subdivisión α2 de clase Proteobacteria. Causa una brucelosis, zoonosis ampliamente distribuida nivel mundial. Los principales síntomas incluyen abortos y esterilidad en ganado, así como fiebre ondulante humanos. En regiones endémicas Centroamérica, brucelosis tiene alto impacto socioeconómico. el Instituto Tecnológico Costa Rica (ITCR) se desarrolló fecha reciente proyecto...
ABSTRACT Genomic data on the foodborne pathogen Listeria monocytogenes from Central America are scarse. We analysed 92 isolates collected in Costa Rica over a decade different regions, compared them to publicly available genomes and identified unnoticed outbreaks. This study calls for mandatory reporting of listeriosis improve surveillance.
Brucella abortus is a facultative extracellular-intracellular bacterial zoonotic pathogen worldwide. It also major cause of abortion in bovines, generating economic losses. The two-component regulatory system BvrR/BvrS modulates the expression genes required to transition from extracellular intracellular lifestyles. However, few regions BvrR direct target have been studied. In this study, we characterized region omp25 , gene encoding an outer membrane protein that positively regulated by TCS...
Animal farming activities can influence soil properties that contribute to the survival of foodborne pathogens like ubiquitous Listeria monocytogenes. However, presence this pathogen in farm-associated soils Costa Rica has not been studied, which might provide new insights regarding environmental conditions associated with establishment pathogen. In work, we correlated L. monocytogenes physicochemical and bacterial community structure livestock activities, including a dairy barn floor (DB)...
Alphaproteobacteria include organisms living in close association with plants or animals. This interaction relies partly on orthologous two-component regulatory systems (TCS), sensor and regulator proteins modulating the expression of conserved genes related to symbiosis/virulence. We assessed ability exoS+Sm gene, encoding a protein from plant endosymbiont Sinorhizobium meliloti substitute its bvrS animal/human pathogen Brucella abortus. ExoS phosphorylated B. abortus BvrR vitro cultured...
Genomic data on the foodborne pathogen Listeria monocytogenes from Central America are scarce. We analyzed 92 isolates collected during 2009-2019 different regions in Costa Rica, compared those to publicly available genomes, and identified unrecognized outbreaks. Our findings suggest mandatory reporting of listeriosis Rica would improve surveillance.
Listeria monocytogenes es un patógeno intracelular oportunista que se ha convertido en una de las causas más importante infecciones transmitidas por alimentos todo el mundo. Debido a la importancia L. salud pública han descrito muchos protocolos para identificación y tipificación este organismo, pero su mayoría son muy complejos larga duración. Por esta razón, desarrolló PCR multiplex, detección rápida sensible bacteria diferentes tipos muestras. El objetivo del presente estudio fue...
Desde el año 2009, Centro de Investigación en Biotecnología (CIB) del TEC ha venido desarrollando varios proyectos investigación interuniversitarios y multidisciplinarios relacionados con la bacteria Brucella abortus. Estos se hicieron conjunto Programa Enfermedades Tropicales (PIET) Escuela Medicina Veterinaria Universidad Nacional (UNA) (CIET) Facultad Microbiología Costa Rica (UCR). La mayoría estos contaron principalmente financiamiento los Fondos Especiales para Educación Superior...
El género Listeria está compuesto por más de 15 especies, que pueden ser aisladas diferentes ambientes, incluyendo vegetación, suelo, agua y animales. L. monocytogenes ha sido mundialmente estudiada como un modelo patogénesis intracelular, lo cual permitido descifrar información importante sobre el comportamiento del patógeno, es caso la respuesta a actividad antibiótica transcripción genes durante vida intracelular desarrollo modelos in vivo para estudio infecciones. Costa Rica una las...
