Porcine circovirus 3 (PCV3) infection has been reported in piglets and sows with porcine dermatitis and nephropathy syndrome, reproductive failure, and cardiac and multisystemic inflammation. Few studies linked PCV3 infection to increased incidence of abortion and weak-born piglets. This is the first report of a detection of PCV3 Hungarian strain in several organs of aborted and weak-born piglets, including the thymus, lymph node, placenta, spleen, kidney and the liver. The tissue tropism of PCV3 in affected litters was analysed using real-time quantitative PCR, and the result showed the highest load of viral DNA in the thymus and lymph nodes. The ORF2 of Hungarian PCV3 strains was 524 nucleotides in length, and the sequence identity to GenBank sequences ranged from 98.5 per cent to 99.2 per cent. The results suggest that PCV3 may have a relevant role in reproductive failure in gilts.

Circovirus porcine (PCV) is a widespread pathogen in swine, consisting of four species: PCV1, PCV2, PCV3, and PCV4. Coinfection with other pathogens exacerbates the severity of Porcine Respiratory Disease Complex (PRDC), leading to significant economic losses. In Brazil, pleurisy lesions in pigs, often due to chronic inflammation from bacterial, viral, and environmental factors, are a major economic concern.

The epidemiological characteristics of emerging infectious disease outbreaks in recent years have underscored the critical importance of controlling imported infectious diseases. In this study, we implemented dynamic tracking of microbial invasions by monitoring environmental microbes at the customs and ports. From July to September 2024, a total of 126 environmental samples were collected from three ports of entry in Shenzhen, China.

Introduction: Detection of porcine circovirus 2 (PCV2) in lymphoid tissues is essential for diagnostic and research purposes. hybridisation (ISH) enables the localisation of viral genomes in tissue sections but is traditionally assessed visually, which may introduce subjectivity.
Methods: This study developed an automated pixel classifier to quantify the PCV2 genome using RNAscope ISH technology.

Porcine circovirus type 3 (PCV3) was identified in 2016 and has since been associated with reproductive failure, multisystemic inflammation, and subclinical infection in swine. Numerous countries have retrospectively detected the presence of PCV3 before its first clinical description in 2016. The reported detection rate of PCV3 has varied from 6.

Canine Infectious Respiratory Disease Complex (CIRDC), caused by a diverse range of viral and bacterial pathogens, is the leading cause of respiratory illness in dogs. In the winter of 2023-2024, the United States experienced a noticeable increase in cases consistent with CIRDC. This study investigated the potential association of emerging pathogens with CIRDC cases.
