... a major concern for the swine industry and causes high degrees of morbidity and mortality. The intracellular signalling cascades of the innate immune system triggered by HP-PRRSV often lead to the elimination of infection. However, HP-PRRSV induces pathological changes and can cause aberrant immune responses in the host, resulting in acute lung injury and immune dysfunction. Studies of the innate immune responses to HP-PRRSV infection are crucial to gaining i...

...ign: justify;">Classical swine fever virus (CSFV) is generally a noncytopathogenic virus in cell cultures. The development of reporter CSFV has provided an excellent option to directly detect viral replication without the use of secondary labeling. This mini-review discusses the applications of reporter CSFV in the study of CSFV biology, including efficiently screening the antivirals against CSFV and viral receptors, conveniently tracking the viral proteins in...

...align: justify;">African swine fever (ASF) is a contagious viral disease of pigs with severe consequences and a growing transboundary potential. The disease is caused by ASF virus (ASFV), the only DNA virus with an arthropod vector of the genus Ornithodoros, involved in its transmission. Tick involvement has been reported in Europe, East and Southern Africa to be part of ASFV transmission cycles. Ticks in an ASFV infected area have been reported to influence t...

This study established a reverse transcription-loop-mediated isothermal amplification (RT-LAMP) assay to detect PRRSV. Four primers were designed targeting the ORF5 gene of PRRSV were designed. Reverse transcription and amplification of the viral RNA using AMV reverse transcriptase was optimal at a constant temperature of 65 °C. The output of the RT-LAMP assay ...

... hematological traits in swine may confer physiological differences, so we studied transcriptome profiles in spleens of Yorkshire pigs with different peripheral blood T lymphocyte subsets. The results showed that 2050 differentially expressed transcripts were identified, with 1554 up-regulated and 496 up-regulated in high and low T lymphocyte groups, respectively. Among differentially expressed genes, IL1B, IL17F, IL6R, CXCL2, CCL20 and CCL25 wer...

In this study, 173 serum samples of Tibetan swine were tested for anti-HEV IgM and IgG antibodies by the ELISA. HEV RNA were measured in feces (n=173), serum (n=173) and tissue ((including liver, spleen, kidney and intestine, n=21) by nested RT-PCR and qRT-PCR. HEV ...

This study aims to determine the histopathological changes of meningoencephalitis and arthritis in post-weaning piglets suspected of streptococcosis. The samples were 35 cadaver of post weaning piglets that showed muscle spasm and swollen joint at several villages in Badung Regency, Indonesia. Samples of the brain and synovial tissue were processed using hematoxylin-eosin dyes (HE). On histopathological examin...

Estrogen receptor 1 (ESR1) gene has been linked to being one of the major genes affecting litter size in swine. The Philippine swine breed is not commonly used on a commercial scale but in backyard production. The aim of the study was to assess the alleli...

Total 40 sows of 7 gestational age with good health and nutritional condition were divided into four groups (n=10): the control group, low calcium, 25(OH)D3 group and low calcium with 25(OH)D3 group. Each groups consist of 5 piglets, randomly selected and euthanized within 2 h after birt...

In this context, pork products can potentially be a source of the spread owing to the long persistence of the causal virus. Therefore, this study aims to analyze ASFV genetically from pork product samples in 2019-2023 based on the B646L gen...
