Intra-host variation structure of classical swine fever virus NS5B in relation to antiviral therapy.
in the RdRp. Interestingly, the frequency of the mutations situated in close proximity to a region involved in antiviral resistance in CSFV and bovine viral diarrhea virus (BVDV) was elevated compared ...
Diagnosis of Schmallenberg virus infection in malformed lambs and calves and first indications for virus clearance in the fetus.
presence of SBV RNA could only be confirmed in part of the SBV suspected newborns examined. To investigate possible causes for non-confirmation by rRT- PCR, a comparative analysis between different organs ...
Efficacy of chimeric Pestivirus vaccine candidates against classical swine fever: protection and DIVA characteristics.
tests were evaluated. The vaccine candidates were compared to the C-strain. All vaccine candidates protected against clinical signs. No transmission to contact pigs was detected in the groups vaccinated ...
CP7_E2alf oral vaccination confers partial protection against early classical swine fever virus challenge and interferes with pathogeny-related cytokine responses.
C-strain vaccines were compared for their efficacy to induce protection against a CSF virus (CSFV) challenge with the moderately virulent Bas-Rhin isolate, in pigs as early as two days post-immunization. ...
Serological and virological BVDV prevalence and risk factor analysis for herds to be BVDV seropositive in Belgian cattle herds.
risk factor to be BVDV seropositive compared to non-vaccinating herds (OR=3.4, p <0.01). Herds reporting BVDV-related problems the past 3 years were more likely to be BVDV seropositive (OR=1.9, ...
Efficacy of rHVT-AI vector vaccine in broilers with passive immunity against challenge with two antigenically divergent Egyptian clade 2.2.1 HPAI H5N1 strains.
10 days. The different groups were challenged with two antigenically highly divergent Egyptian dade 2.2.1 H5N1 HPAIV s at 4 wk of age. Protection against challenge was compared with unvaccinated birds ...
Evaluation of four enzyme-linked immunosorbent assays for the serologic survey of avian influenza in wild bird species.
Synbiotics FluDETECTBE, and BioChek AIMS p) were compared for the serologic analysis of 172 serum samples from mallard, mute swan, and Canada goose. Samples were selected based on ID-Vet IDS creen results to ...
Evaluation of classical swine fever virus antibody detection assays with an emphasis on the differentiation of infected from vaccinated animals.
Comparable sensitivity was shown by the Chekit* CSF-Marker, an Erns ELISA. However, this test does not allow differentiation between antibodies directed against ruminant pestiviruses and those against CSFV. ...
Risk factors associated with brucellosis seropositivity among cattle in the central savannah-forest area of Ivory Coast.
seropositivity was associated with age and herd size. Cattle above 5 years of age were found to have a higher chance of being seropositive (odd ratio (OR)=2.8; 95% CI: 1.3, 6.4) compared to cattle under 3 years of ...
Assessment of the long-term effect of vaccination on transmission of infectious bovine rhinotracheitis virus in cattle herds hyperimmunized with glycoprotein E-deleted marker vaccine.
seroconversion was compared among experimental groups via a shared frailty model with a piecewise constant baseline risk to correct for seasonal and secular effects. RESULTS: Risk for gE seroconversion ...
