Endoparasites Infecting Domestic Animals and Spectacled Bears (Tremarctos ornatus) in the Rural High Mountains of Colombia.

Abstract

Simple SummaryThe spectacled bear (Tremarctos ornatus) is a threatened species, a member of the Ursidae family that lives in the Andes rural high mountain territories of Colombia, Venezuela, Ecuador, Peru, and Bolivia near livestock areas. Parasites in the spectacled bear are a relevant area of interest to preserve this species and understand its habitats and interactions with farm animals. The present work aimed to evaluate the presence of endoparasites in both T. ornatus and domestic animals in these areas, by copro- parasitological examination. The results indicate that some parasites have zoonotic potential in wild endangered species and domestic animals in Colombian regions. More sensitive molecular techniques are needed for further identification of the parasite species.This research described the co-infection prevalence of endoparasites in Tremartus ornatus and domestic animals in the rural high mountains of Colombia by copro-parasitological examination. Some parasites have a zoonotic potential in wild endangered species and domestic animals in Colombian regions. T. ornatus had a notable infection with Eimeria spp., Ascaris spp., Ancylostoma spp., and Baylisascaris spp. Cryptosporidium spp., Balantidium coli, Anoplocephala spp., and Acanthamoeba spp. In B. taurus, Eimeria spp. is coinfecting with Cryptosporidium spp. (6.6%) and represents 18% of the total parasitism. In E. caballus and B. taurus. Eimeria spp. coinfecting (34.7%), with the Strongylus spp. (21.9–25%). In T. ornatus, Eimeria spp. is coinfecting with Ancylostoma spp. (36.2%), Cryptosporidium spp., Ascaris spp., Baylisascaris spp., and B. coli.
