Unraveling chromosomal and genotoxic damage in individuals occupationally exposed to coal from underground mining.

Purpose: Coal mining is a vital sector in Colombia, contributing significantly to the nation's economy and the development of its regions. However, despite its importance, it has led to a gradual decline in the health of mine workers and nearby residents. While the adverse health effects of open-pit coal mining on exposed individuals have been well-documented in Colombia and globally, studies investigating genetic damage in underground coal miners are lacking.

Carriage of Clostridium perfringens in domestic and farm animals across the central highlands of Colombia: implications for gut health and zoonotic transmission.

Clostridium perfringens inhabits the guts of humans and animal species. C. perfringens can proliferate and express an arsenal of toxins, promoting the development of multiple gut illnesses.

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.

Molecular detection and characterization of spp., spp., and in captive wild animals rescued from central Colombia.

, , and are significant causes of diarrhea worldwide. However, studies on their prevalence in wild animals are limited, compared to humans and domestic animals. In this study, we collected 23 stool samples from captive wild rescued animals in Boyacá, Colombia.

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.

Serodiagnosis and Risk Factors Associated with Infectious Agents of Reproductive Diseases in Bovines of Chiquinquirá, District of Boyacá (Colombia).

The productivity of cattle farms is affected by infectious and noninfectious factors that generate economic losses and cause reproductive failure represented by low conception rates, embryonic mortality, abortions, and fetal mummification. The infectious agents that most impact the reproductive health of the bovine species from conception to birth are bovine herpesvirus type 1 (BoHV-1) causing infectious bovine rhinotracheitis (IBR), bovine viral diarrhea virus (BVDV), bovine parainfluenza virus type 3 (PI3), and spp. The objective of this study was to diagnose the presence of BoHV-1, bovine viral diarrhea (BVD), PI3, , and spp.

Seropositivity and risk factors associated with the presentation of bovine leukosis virus in Sotaquirá, Colombia.

Background And Aim: Enzootic bovine leukosis is a disease economically important to the dairy farming industry worldwide. The virus is of the Deltaretrovirus genus and is primarily transmitted iatrogenically. Most bovines infected with the virus remain asymptomatic with only 5-10% of cattle having lymphomas.

Seroprevalence of bovine viral diarrhea virus (BVDV) in cattle from Sotaquirá, Colombia.

Worldwide distributed Bovine Viral Diarrhea Virus (BVDV) represents a high risk of infection in most bovine farms, in which it is associated with gastrointestinal, respiratory, and reproductive diseases. The purpose of this research was to establish the seroprevalence and the main risk factors associated with the presentation of BVDV in the municipality of Sotaquirá, Colombia. Samples were taken from 1000 cattle of Holstein, Ayrshire, Jersey, Normande Gyr and Holstein x Gyr.

Identification of Multiple Subtypes in Domestic Animals From Colombia Using Amplicon-Based Next Generation Sequencing.

is frequently reported in fecal samples from animals and humans worldwide, and a variety of subtypes (STs) have been observed in wild and domestic animals. In Colombia, few studies have focused on the transmission dynamics and epidemiological importance of in animals. In this study, we characterized the frequency and subtypes of in fecal samples of domestic animals including pigs, minipigs, cows, dogs, horses, goats, sheep, and llama from three departments of Colombia.

Describing the intestinal microbiota of Holstein Fasciola-positive and -negative cattle from a hyperendemic area of fascioliasis in central Colombia.

The ability to identify compositional changes in the intestinal microbiota of parasitized hosts is important for understanding the physiological processes that may affect animal productivity. Within the field of host-parasite interactions, many studies have suggested that helminths can influence the microbial composition of their hosts via their immunomodulatory effects. Bovine fascioliasis is a helminthiasis widely studied by immunologists, but with little information available regarding gut microbial communities.

[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.
