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.

Several lineages of porcine epidemic diarrhea virus in Colombia during the 2014 and 2016 epidemic.

Porcine epidemic diarrhea virus (PEDV) is a significant global, enteric coronavirus in pigs and was first reported in Colombia in 2014. However, the epidemiology, genetic and antigenic characteristics of the virus have yet to be investigated. In this study, we investigated the dissemination of PEDV by testing 536 samples by RT-PCR over a 33-month period.

Detection and molecular characterization of porcine circovirus type 2 from piglets with porcine circovirus associated diseases in Colombia.

Background: The porcine circovirus-associated disease (PCVAD) has been known since 1991 in Canada, but the first outbreak of PCVAD in Colombia was reported in 2007. In order to understand the molecular epidemiology of the disease and to establish the origin of the virus in the country, the study presented here intended to evaluate the presence of PCV2-associated systemic infection in piglets from different geographical regions over a period of 9-years (2002-2010). The analysis included samples collected before, during and after outbreaks of PCVAD in pigs from Colombia.
