Feline gastrointestinal eosinophilic sclerosing fibroplasia (FGESF) is a recently described inflammatory condition of domestic cats with unknown aetiology. A proportion of cases of FGESF are associated with bacteria, but antibiotic treatment is ineffective. It has been hypothesized that genetically predisposed cats may develop FGESF in response to the(More)
African swine fever virus (ASFV) is the causal agent of African swine fever, a hemorrhagic and often lethal porcine disease causing enormous economical losses in affected countries. Endemic for decades in most of the sub-Saharan countries and Sardinia, the risk of ASFV-endemicity in Europe has increased since its last introduction into Europe in 2007. Live(More)
Rotavirus is a worldwide major cause of diarrhea outbreaks in neonatal ruminants. An outbreak of ovine diarrheic syndrome (ODS) in 50-75 days-old lambs (weaned lambs) is described. Fecal immunochromatography and intestinal immunohistochemistry for rotavirus group A were performed. In addition, semi-nested multiplex RT-PCR for G and P rotavirus genotyping in(More)
Necrotizing lymphadenitis is observed in approximately 2% of pigs affected by post-weaning multisystemic wasting syndrome (PMWS). The pathogenesis of the lesion has been linked to apoptosis induced by porcine circovirus type 2 (PCV2). The aim of the present study was to gain further insights into PCV2-associated lymphoid necrosis in pigs with PMWS. Three(More)
In this study, a new in situ hybridisation (ISH) protocol has been developed to identify African swine fever virus (ASFV) genome in formalin-fixed, paraffin-embedded tissues. Different digoxigenin labelled ASFV-probes were tested, including single ASFV-specific oligonucleotides, an 18.5kb restriction fragment from the viral genome and the entire ASFV(More)
Porcine reproductive and respiratory syndrome virus (PRRSV) is endemic in most parts of Asia, where genotype I and II strains of diverse virulence may coexist. This study evaluated the outcome of infection with a highly virulent Asian genotype II PRRSV isolate in piglets vaccinated with a genotype I vaccine. Twenty-one 3-week-old piglets were divided in(More)
The lack of available vaccines against African swine fever virus (ASFV) means that the evaluation of new immunization strategies is required. Here we show that fusion of the extracellular domain of the ASFV Hemagglutinin (sHA) to p54 and p30, two immunodominant structural viral antigens, exponentially improved both the humoral and the cellular responses(More)
The increasing interest in Rift Valley fever virus (RVFV) and its potential impact on naive animal populations deserve revisiting experimental reproduction of RVFV infection, particularly in those animal breeds for which no data about their susceptibility to RVFV infection have ever been recorded. In this study we show the susceptibility of 9-10 weeks old(More)
African swine fever is still one of the major viral diseases of swine for which a commercial vaccine is lacking. For the design and development of such preventive products, researchers involved in African swine fever virus (ASFV) vaccinology need standardized challenge protocols and well characterized clinical, pathological and immunological responses of(More)
Pigs were immunized with DNA plasmids containing different open reading frames (ORFs) of a porcine reproductive and respiratory syndrome virus (PRRSV) genotype I strain. One group was injected with three inoculations of ORF7, a second group was immunized with three inoculations of plasmids containing ORF5 and ORF6, and a third group was kept as controls.(More)
