Risk factors associated with enzootic bovine leukosis in Boyacá and Cundinamarca municipalities, Colombia.

Background: Enzootic bovine leukosis (EBL) is a lymphoproliferative disorder caused by the bovine leukemia virus (BLV), a virus of the Retroviridae family. The infection is distributed worldwide, and a high percentage of animals infected by the BLV are asymptomatic and act as carriers of the virus in many cattle populations.

Aim: To identify the risk factors associated with EBL in the municipalities of Boyacá and Cundinamarca (Colombia).

Seroprevalence and risk factors of bovine fasciolosis in the municipalities of Colombia.

Background And Aim: Bovine fasciolosis is a reemerging neglected disease with a worldwide distribution caused by the trematode spp., which parasitize various hosts. Bovine fasciolosis is responsible for large economic losses in the bovine livestock sector.

Seroprevalence and risk factors associated with the presence of bovine leptospirosis in the municipality of Sotaquirá, Colombia.

Background: Bovine leptospirosis is a zoonotic, infectious, and cosmopolitan disease of worldwide distribution, caused by the spirochete spp., which has been diagnosed in humans; domestic mammals, such as dogs, sheep, goats, swine, horses and cattle; and wild animals. It is considered a significant cause of economic losses in livestock because it causes infertility, abortion and reduced milk production.

Seroprevalence and risk factors associated with bovine herpesvirus 1 in dairy herds of Colombia.

Background And Aim: Infectious bovine rhinotracheitis (IBR) is an infectious disease widely distributed globally and is considered the main cause of various reproductive and respiratory tract diseases in cattle and buffaloes. This study aimed to estimate seroprevalence and determine risk factors associated with the presentation of IBR in the municipality of Sotaquirá, Boyacá (Colombia).

Materials And Methods: A descriptive cross-sectional study with simple random sampling was performed, and the sample size was 1,000 cattle.

[Nematodes with zoonotic potential in parks of the city of Tunja, Colombia].

Objective: To identify the presence of parasites with zoonotic potential in major parks in the city of Tunja, Boyacá.

Materials And Methods: Twenty eight parks in the city were selected, where 124 samples of feces of dogs and soil were collected with the help of a spatula, gathering approximately 150 g per sample. They were processed by the method of concentration of Ritchie modified making the identification of parasitic forms in an optical microscope.
