RESUMEN
RESUMEN Introducción:
Las Rickettsias son un género de bacterias Gram negativas intracelulares obligadas causantes de muchas epidemias en el mundo y son transmitidas principalmente por garrapatas, pulgas, piojos y ácaros. Las rickettsiosis son enfermedades infecciosas reemergentes sin vigilancia epidemiológica en Colombia. Hasta hace pocos años Rickettsia rickettsi era la única Rickettsia transmitida por garrapatas presente en América; sin embargo, nuevas especies están siendo descritas, y aunque su patogenicidad no ha sido confirmada pueden ser consideradas patógenos potenciales.Objetivo:
Determinar la presencia de rickettsias en garrapatas del departamento del Meta, Colombia. Material yMétodos:
Se realizó un estudio descriptivo de corte transversal, fueron colectadas garrapatas y después de su identificación taxonómica, los genes gltA, ompA y ompB fueron amplificados y secuenciados.Resultados:
Se obtuvieron un total de 169 grupos a los que se les realizó PCR de los cuales 2 grupos amplificaron para los genes gltA, ompA y ompB.Conclusiones:
Los resultados demuestran la presencia de Rickettsia spp en garrapatas del departamento del Meta.ABSTRACT
ABSTRACT Introduction:
Rickettsia is a genus of Gram-negative obligate intracellular bacteria that cause several epidemics around the world and are transmitted mainly by ticks, fleas, lice and mites. Rickettsiosis is a re-emergent infectious disease without epidemiological surveillance in Colombia. Until few years ago, Rickettsia rickettsi was the only tick-borne Rickettsioses in America; however, new species are being described, and although their pathogenicity has not been confirmed, they should be considered as potential pathogens.Objective:
The aim of this study was to determine the presence of rickettsial agents in ticks in the state of Meta, Colombia. Material andMethods:
A descriptive cross-sectional study was conducted; ticks were collected and, after their taxonomic identification, gltA,ompAand ompB genes were amplified and sequenced.Results:
A total of 169 pools were obtained to which PCR were carried out, of which 2 PCR were amplified for the gltA, ompA and ompB genes.Conclusions:
These results demonstrate the presence of Rickettsia spp in ticks in the State of Meta.
