Avian Metapneumovirus Subtype B Circulation in Poultry and Wild Birds of Colombia.

The global poultry industry, as a leading producer of animal protein, faces significant challenges related to animal health and production due to high bird density and disease risks. A major concern is the Avian Respiratory Complex (ARC), a multifactorial health issue involving pathogens such as avian metapneumovirus (aMPV), an often-underdiagnosed component of the ARC. Wild birds are seen as reservoirs and spreaders of the virus.

Sequence-based epitope mapping of high pathogenicity avian influenza H5 clade 2.3.4.4b in Latin America.

High Pathogenicity Avian Influenza (HPAI) poses a significant threat to public and animal health. Clade 2.3.

Antimicrobial Resistance Profiles of Isolated from Cows with Subclinical Mastitis: Do Strains from the Environment and from Humans Contribute to the Dissemination of Resistance among Bacteria on Dairy Farms in Colombia?

is a very prevalent etiologic agent of bovine mastitis, and antibiotic resistance contributes to the successful colonization and dissemination of these bacteria in different environments and hosts on dairy farms. This study aimed to identify the antimicrobial resistance (AMR) genotypes and phenotypes of spp. isolates from different sources on dairy farms and their relationship with the use of antibiotics.

Sequence-Based Antigenic Analyses of H1 Swine Influenza A Viruses from Colombia (2008-2021) Reveals Temporal and Geographical Antigenic Variations.

Swine influenza is a respiratory disease that affects the pork industry and is a public health threat. It is caused by type A influenza virus (FLUAV), which continuously undergoes genetic and antigenic variations. A large amount of information regarding FLUAV in pigs is available worldwide, but it is limited in Latin America.

Proteomics and Genetic Approaches Elucidate the Circulation of Low Variability Staphylococcus aureus Strains on Colombian Dairy Farms.

Staphylococcus aureus is one of the most prevalent pathogens causing bovine mastitis in the world, in part because of its ease of adaptation to various hosts and the environment. This study aimed to determine the prevalence of S. aureus in Colombian dairy farms and its relationship with the causal network of subclinical mastitis.

New Insights into Avian Infectious Bronchitis Virus in Colombia from Whole-Genome Analysis.

Infectious Bronchitis (IB) is a respiratory disease caused by a highly variable , which generates a negative impact on poultry health worldwide. GI-11 and GI-16 lineages have been identified in South America based on Infectious Bronchitis virus (IBV) partial S1 sequences. However, full genome sequence information is limited.

Characterization and evaluation of Colombian propolis on the intestinal integrity of broilers.

Nutritional additives such as propolis seek to improve intestinal health as an alternative to the global ban on in-feed antibiotics used as growth promoters (AGP). The objective of this study was to evaluate the effect of propolis supplementation in diet of broilers. Four hundred and fifty straight-run Ross 308 AP broilers were fed with a basal diet (BD) throughout the whole experimental period.

Zooming in on the molecular characteristics of swine influenza virus circulating in Colombia before and after the H1N1pdm09 virus.

Influenza is one of the most critical viral agents involved in the respiratory disease complex affecting swine production systems worldwide. Despite the absence of vaccination against swine influenza virus in Colombia, the serologic reactivity to classic H1N1 and H3N2 subtypes reported since 1971 indicates the virus has been circulating in the country's swine population for several decades. However, successful isolation and sequencing of field virus from pigs was nonexistent until 2008, when H1N1 classical influenza virus was identified.

Rhabdoid melanoma in a harpy eagle ().

A 28-year-old male harpy eagle () with a history of anorexia, hyporexia, lethargy, and progressive weight loss was found dead and submitted for post-mortem examination. Gross findings include dark brown discolouration of testes and lungs; the testes were bilaterally enlarged, glistening brown-grey to blackish in appearance, firm, smooth, and multilobulated. The lungs contained a mass with similar features to the testicles, irregularly shaped with multiple nodules.

Key Factors That Enable the Pandemic Potential of RNA Viruses and Inter-Species Transmission: A Systematic Review.

Viruses play a primary role as etiological agents of pandemics worldwide. Although there has been progress in identifying the molecular features of both viruses and hosts, the extent of the impact these and other factors have that contribute to interspecies transmission and their relationship with the emergence of diseases are poorly understood. The objective of this review was to analyze the factors related to the characteristics inherent to RNA viruses accountable for pandemics in the last 20 years which facilitate infection, promote interspecies jump, and assist in the generation of zoonotic infections with pandemic potential.

Bilateral osteoma cutis in a Peach-Faced Lovebird (Agapornis roseicollis).

An osteoma is an infrequent tumor documented in avian species. An adult female Peach-Faced Lovebird (Agapornis roseicollis) with a history of previous trauma was examined due to the presence of bilateral hard and yellowish-white masses in the radio-cubital humerus junction. Histopathological dermal examination revealed a non-neoplastic process of mesenchymal origin, characterized by the formation of well-differentiated trabecular bone, multiple areas of medullary bone and loose connective tissue and coagulation of the necrosis foci.

Characterization of hygiene habits and environments in children's care homes.

Objective: Identify the hygiene habits of children and caregivers in order to prevent and control infectious diseases in care environments in Bogotá, Colombia, as well as characterize the surface bacteria in these environments.

Method: Instruments were designed, validated and applied to evaluate healthy habits, with samples taken from surfaces in kitchens, bathrooms, halls, mats, and tools in 230 locations. Th e isolated bacteria were classifi ed using automated methodologies.
