Parasitological and serological evaluation of hemotropic infections in white-tailed deers (odocoileus virginianus) in Venezuela

Abstract:

The objective of this research was the parasitology and serology evaluation of the presence of Anaplasma spp., Trypanosoma spp. y Babesia spp in white tail dear (Odocoileus virginianus) in a region of Apure State in which them coexist with infected bovines (Bos taurus), horses (Equus caballus) and capybaras (Hydrochoerus hydrochaeris). For that, five whitetailed deer were captured in the Cedral Ranch, and the infection by these parasites where explored through blood smear and serological assays by inmunofluorescen and inmunoblot (Western Blot) using as antigens the soluble sonicated of Trypanosoma evansi and the recombinant Mayor Surface Protein (MSP5) of Anaplasma marginale. Two deers were detected positive for Anaplasma marginale by stained blood smear and no positives for Trypanosoma spp. or Babesia spp. One deer was seropositive for A. marginale and two were seropositive for Trypanosoma evansi. The above results suggest that the Odocoileus virginianus could be participating in the natural hemotropic cycle of A. marginale and T. evansi, together with the extensive production of Bos taurus, Equus caballus and Hydrochoerus hydrochaeris in this region of Venezuela.
