Resumen en inglés
Introduction: Zoonotic infections have always been among the wide range of human diseases and most such as brucellosis, tuberculosis, bubonic plague, yellow fever and influenza, come from domestic animals, arthropods, poultry and livestock. Rodents, playing an important role in ecology and in the transmission of new diseases. Aim: A search for zoonotic infectious agents transmitted by rodents (Rodentia) was carried out as part of a surveillance program in periurban and rural areas of the municipality of Villavicencio during the years 2018-2020. Methods: An observational-descriptive, cross-sectional study was carried out to monitor the presence of some infectious zoonotics (Leptospira spp, Yersina pestis, Trypanosoma cruzi, Orthohantavirus and Mammarenavirus) transmitted by rats and mice of importance in public health, by means of the use of molecular techniques for the standardization of laboratory and surveillance protocols. Results: 50 rodents were captured in domiciliary, peridomiciliary and field areas. 12% of the rodents amplified the pfLp32 markers for the identification of Leptospira interrogans and 10% amplified the Yp marker for the detection of Yersinia pestis, with Rattus rattus being the species with the highest frequency in both results. During the investigation it was not possible to amplify markers for Trypanosoma cruzi, Orthohantavirus and Mammarenavirus. Conclusion: The presence of L. interrogans and the possible presence of Y. pestis were confirmed in renal tissue and spleen of synanthropic and wild roedodes from Villaviciencio, which could become a cycle of infections in the region. Recommendations: Surveillance of rodent populations allows knowing the interaction between pathogens and their hosts and other species in the face of emerging zoonotic diseases that in turn allow the implementation of prevention and control programs in human emergencies, seeking mitigation strategies to provide effective and timely responses
