RESUMO

RESUMEN Las garrapatas son artrópodos de gran impacto sobre la economía pecuaria y la salud humana debido a las pérdidas generadas en la producción, y a su capacidad de transmitir microorganismos. Pese a la evidencia de circulación de una gran diversidad de garrapatas en Colombia, no se cuenta con compilaciones actualizadas de la variedad de especies presentes, por lo cual los autores presentan una revisión de literatura sobre las garrapatas de la familia Ixodidae reportadas en Colombia incluyendo su distribución geográfica, sus hospederos y los microorganismos reportados en aquellas especies registradas en este país. En la recopilación se evidenció la presencia en Colombia de diferentes especies de garrapatas de los géneros Amblyomma, Ixodes, Haemaphysalis, Rhipicephalus y Dermacentor. El género con mayor variedad fue Amblyomma con 29 especies, seguido de Ixodes con 11 especies, y de los géneros Dermacentor, Haemaphysalis y Rhipicephalus se reportaron dos especies para cada uno. Las especies se distribuyeron en la mayoría de los departamentos de Colombia y en una amplia diversidad de hospederos entre los cuales se incluyen animales domésticos, sinantrópicos y silvestres. Adicionalmente se encontró que algunas garrapatas reportadas podrían jugar un papel como vectores potenciales de diversos microorganismos que pueden afectar a la salud publica y veterinaria. Esperamos que este trabajo sea un aporte para apoyar la investigación en garrapatas y el estudio de los agentes transmitidos por estas en Colombia.


ABSTRACT Ticks are arthropods with significant impact on the economy of livestock and public health, due to losses generated in production, and their ability to transmit microorganisms. Despite the evidence of circulation of different tick species in the country, there are no updates concerning the variety of existing species, therefore, the authors of this manuscript offer a literature review on ticks from the Ixodidae family reported in Colombia including their geographical distribution, their hosts and the microorganisms they carry and might transmit in Colombia. In this manuscript, we described the presence in the country of different species of ticks of the genera Amblyomma, Ixodes, Haemaphysalis, Rhipicephalus, and Dermacentor. The genus with the greatest variety was Amblyomma with 29 species, followed by Ixodes with 11 species, and of the genus Dermacentor, Haemaphysalis and Rhipicephalus two species were reported for each. These species are distributed in most departments and a wide variety of hosts, including domestic, synanthropic and wild animals. Additionally, it was found that some reported ticks could play a role as potential vectors of various microorganisms that could affect public and veterinary health. We expect that this work will be a contribution to support tick research and the study of tick-borne agents in Colombia.

RESUMO

Abstract INTRODUCTION: In Colombia, there is insufficient epidemiological surveillance of zoonotic hemorrhagic viruses. METHODS: We performed a sero-epidemiological study in indigenous populations of Wayuü, Kankuamos, and Tuchin communities using Maciel hantavirus and Junin arenavirus antigens for IgG detection by ELISA. RESULTS IgG antibodies to hantavirus and arenavirus were found in 5/506 (1%) and 2/506 (0.4%) serum samples, respectively. CONCLUSIONS: Arenavirus and hantavirus circulate in indigenous populations from the Colombian Caribbean region, and the results indicate that the indigenous populations are exposed to these zoonotic agents, with unknown consequences on their health, despite low seroprevalence.
