Abstract:
... Air and surfaces of swine farms are the two alternative samples to obtain information about the health status of the herd. The aim of this study was to assess air and surface sampling for the detection of porcine circovirus type 2 (PCV2) in vaccinated and unvaccinated fattening farms, studying the relationship between the viral load in these samples with the viremia at herd level. Three swine fatt ...

Abstract:
... BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) is a hyperinflammatory condition with uncontrolled activation of lymphocytes and macrophages. Besides a primary (genetic) form, HLH can also be triggered by malignant, autoimmune and infectious diseases. HLH recurrences are rarely described, usually only in primary HLH. Parvovirus B19 (PVB19) Infection is one of the rare and rather benign causes ...

Abstract:
... Real-world experience with low-level viraemia (LLV) and its impact remain less reported among people living with HIV (PLWH) who receive antiretroviral therapy (ART) containing second-generation integrase strand transferase inhibitors, including dolutegravir and bictegravir. This retrospective cohort study included virally suppressed PLWH who achieved plasma HIV-RNA viral load (PVL) <50 copies/mL f ...

Abstract:
... The objective of the present study was to evaluate the potential risks of the four commercial PRRS-1 MLV vaccines in pregnant vaccinated gilts at the last stage of gestation under field conditions. The study was conducted at four pig farms, including 25 gilts from each farm (25 × 4 = 100 gilts), which were equally allocated to five different study groups. A PRRS-1 MLV vaccination was applied on th ...
... Classical swine fever (CSF) is a highly contagious and important swine disease in China. Sporadic outbreaks with mild clinical signs are still being reported despite massive vaccination with the CSF C-strain vaccine. One possible reason for vaccine failure could be interference from maternally derived antibodies (MDAs) during vaccination in the field. The aim of this study was to evaluate the effi ...
... Subgroup K avian leukosis virus (ALV-K) is a new subgroup of avian leukosis virus (ALV) first identified in Chinese indigenous chickens in recent years. In this study, an ALV-K strain was isolated from Luhua chicken in Shandong province, China, and designated SD20LH01. The full-length genomic sequence of SD20LH01 was 7491 bp, which had the highest homology with ALV-K reference strains GDFX0601, GD ...
... Senecavirus A (SVA) infection in pigs causes vesicular disease and results in a short viremia and transient shedding of the virus, mainly in oral fluids and feces. Here we describe the consistent prolonged shedding of SVA in the semen of 2 boars, and persistence of SVA within the tonsils and testes of 3 adult boars. Two SVA-infected boars that were identified on a Minnesota sow farm in 2017 shed S ...

... Yellow fever (YF) vaccination is known to induce a suboptimal response in patients with autoimmune diseases (AIDs). To date, few studies have focused on the performance of 17DD-YF vaccination in patients with spondyloarthritis (SpA). In general, patients with SpA are young and have less comorbidities than other patients with AIDs, and frequently receive biological disease-modifying antirheumatic d ...

Abstract:
... BACKGROUND: Torquetenovirus (TTV), a widespread anellovirus recognized as the main component of the healthy human virome, displays viremia that is highly susceptible to variations in immune competence. TTV possesses microRNA (miRNA)-coding sequences that might be involved in viral immune evasion. Among TTV-encoded miRNAs, miRNA t1a, t3b, and tth8 have been found in biological fluids. Here, the pre ...

Abstract:
... A new porcine circovirus type 2e (PCV2e) genotype was recently isolated from diseased pigs. To investigate the pathogenicity of PCV2e, groups of conventional pigs were inoculated in one of three ways: with PCV2e only, with Mycoplasma hyopneumoniae and PCV2e, or with PCV2e and porcine reproductive and respiratory syndrome virus (PRRSV). Pigs were examined post mortem at 21 days post inoculation. Pi ...
... Equine coronavirus (ECoV) causes pyrexia, anorexia, lethargy, and sometimes diarrhoea. Infected horses excrete the virus in their faeces, and ECoV is also detected in nasal samples from febrile horses. However, details about ECoV infection sites in the intestinal and respiratory tracts are lacking. To identify the ECoV infection sites in the intestinal and respiratory tracts, we performed an exper ...

Abstract:
... (1) Background: As the pandemic months progress, more and more evidence shows that the placenta acts as a “barrier” to SARS-CoV-2, although rare cases of vertical transmission have been described. (2) Methods: In an attempt to investigate whether the symptoms’ severity was related to different placental histological characteristics and the immune microenvironment, we subdivided 29 placentas from 2 ...

Abstract:
... Dengue virus (DENV) infection is a significant global health problem. There are no specific therapeutics or widely available vaccines. Early diagnosis is critical for patient management. Viral RNA detection by multiplex RT-PCR using multiple pairs of primers/probes allowing the simultaneous detection of all four DENV serotypes is commonly used. However, increasing the number of primers in the RT-P ...

Abstract:
... BACKGROUND: There were large outbreaks of high pathogenicity avian influenza (HPAI) caused by clade 2.3.4.4e H5N6 viruses in the winter of 2016–2017 in Japan, which caused large numbers of deaths among several endangered bird species including cranes, raptors, and birds in Family Anatidae. In this study, susceptibility of common Anatidae to a clade 2.3.4.4e H5N6 HPAI virus was assessed to evaluate ...

Abstract:
... BK polyomavirus (BKPyV) is a human DNA virus generally divided into twelve subgroups based on the genetic diversity of Viral Protein 1 (VP1). BKPyV can cause polyomavirus-associated nephropathy (PVAN) after kidney transplantation. Detection of BKPyV DNA in blood (viremia) is a source of concern and increase in plasma viral load is associated with a higher risk of developing PVAN. In this work, we ...

Abstract:
... Equid alphaherpesvirus 1 (EHV-1) is prevalent in China, and causes notable economic damage to the equine industry. However, there is no information regarding the molecular characteristics and pathogenicity of the Chinese strains. Therefore, an EHV-1 strain, named YM2019, was isolated from the lung tissue of an aborted horse fetus in Xinjiang, China, and its genome and pathogenicity were analyzed. ...

Abstract:
... High genetic diversity of porcine reproductive and respiratory syndrome virus (PRRSV) isolates is a major obstacle for the development of effective PRRS vaccines. A chimeric highly pathogenic PRRSV2 (HP-PRRSV2) strain containing the consensus sequence of ORF2-6 genes was constructed in our previous study, which could induce broadly neutralizing antibodies (bnAbs) and confer satisfied cross protect ...
... Medications studied for therapeutic benefits in coronavirus disease 2019 (COVID-19) have produced inconclusive efficacy results except for steroids. A prospective randomized open-label, parallel-arm Phase I/II clinical trial was planned to compare essential oil (EO) blend versus placebo nebulization in mild COVID-19. A Phase I safety evaluation was carried out in a single ascending and multiple as ...
... Elephant endotheliotropic herpesvirus (EEHV) is one of the most important causes of mortality in Asian elephants (Elephas maximus). The unusual tropism of EEHV for endothelial cells of capillaries can lead to catastrophic vascular dysfunction, hemorrhage, cardiac damage, and death. Cardiac troponin I (cTnI) is an intracellular protein of cardiomyocytes that is released into circulation in levels d ...
