Dr. Benavides got his DVM from the Universidad de Caldas Colombia with a Veterinary Master of Science at the Universidade Federal de Vicosa - Brasil and Ph.D. in 2017 in Immunology and Infectious Diseases, Washington State University, US. Nowadays, he is an Associate Professor in the animal science Department working on Parasitology Immunology, and Infectious diseases in the Universidad Nacional de Colombia (UNAL), working with undergraduate and graduate courses offering the courses of Parasitology, Preventive Medicine as well as Microbiology/Immunology/Parasitology and Infectious diseases. He has developed studies on Protozoa, Virus and Ticks and tick-borne diseases, helminths, and protozoa that affect farming in Colombia. Recently he focused on wild and remerging conditions with zoonotic potential and parasites that affect humans and animals. He has developed different administrative positions at the National University of Colombia (Sep 2017 / Sep 2019) in the Committee of Research and Extension and the Master and Doctoral Committee. He got funding to fortify his Lab to prevent and reduce the impact of animal and human disease on production systems. In 2019 their team got 500.000 US$, 2.000.000.000 COL$, to get a new Confocal Microscopy and the Microscopy Center at the UNAL Palmira. After his Ph.D. at Washington State University, he finished his first project titled Parasites of children and animals in rural high-mountain communities of the Valle del Cauca – Colombia. He is currently (Oct-2020- 2021), Director of the Animal Science Department and Microscopy Lab Center.

Abstract

Introduction

Parasites in Andean bears Tremartus ornatus are a relevant area of interest. Here we present a first study of the endoparasites species infecting T. ornatus and domestics animals in rural high mountains of Colombia

Methods

This is a cross-sectional study using coprological techniques in order to identify domestic and wild parasites on the border of the reserve forest, directly from the rectum or fresh samples.

Results

A total population of 98/264 specimens tested positive for at least one parasite (60.93%). We identified a different prevalence in each sampled species: 35/58 in T. ornatus (60%) [95% CI = 48% - 73%], 31/112 in B. taurus (28%) [95% CI = 8%-26%], and 22/48 in Equus caballus (46%) [95% CI = 26%-60%]. The most prevalent parasites in T. ornatus were Eimeria spp. (30%) [95% CI = 18.2% - 41.8%], Ascaris spp. (21.7%) [95% CI = 11.1% - 32.3%], Ancylostoma spp. (15 %) [95% CI = 5.8% - 24.2%], Baylisascaris spp. (13.3%) [95% CI = 4.6% - 22.1%], Cryptosporidium spp. (10%) [95% CI = 2.3% - 17.7%], Balantidium coli (5%) [95% CI = 0.6% - 10.6%], Anoplocepha spp. (3.3%) [95% CI = 1.3% - 8.0%], and Acanthamoeba spp. (1.7%) [95% CI = 1.6% - 5%].

Conclusions

Endoparasites such as Eimeria spp. in T. ornatus are abundant, but the species circulating, and their level of pathogenicity are unknown. Cryptosporidium spp. and Buxtonella sulcata are common parasites in T. ornatus, B. taurus and E. caballus that require further studies around the circulating species and the clinical effects in these populations
