Porcine circovirus infections are caused by a virus of the genus Circovirus, and there are four known serotypes of this virus. Of these, PCV4 is the most pathogenic and has previously only been detected in CHINA, SOUTH KOREA and Thailand. However, a new study conducted at the University of Extremadura has shown the presence of infection in wild boars and domestic Iberian pigs in Spain.
it is interesting to note that the virus has not been detected in animals living in the east and northeast of the country and in Italy. This suggests possible intraspecific and interspecific transmission of infection, with wild boars most likely being a potential reservoir of the virus.
The scientific researchers also found that porcine circovirus type 4 has high genomic identity with mink circovirus, reaching 66.9%. This indicates the possibility of transmission of infection between different animal species. In addition, in isolated cases it has been observed that this type of infection can be transmitted to dogs.
This discovery is of great importance for veterinary medicine, as it allows us to better understand the mechanisms of spread and transmission of the virus. This also highlights the need to take precautions and develop strategies to control and prevent the spread of circovirus infections in pigs and other animal species.
The results of this study are an important step in the control of viral infections in pigs and highlight the need for ongoing monitoring and development of effective programs to control the spread of viruses.
