Newborn Holstein bull calves (n = 32) were assigned to receive a colostrum supplement (CS) containing defibrinated bovine plasma or a colostrum replacer (CR) containing an immunoglobulin concentrate obtained by concentrating the immunoglobulin (Ig)G fraction of bovine plasma. The CS and CR contained 11.1 and 21.2% of dry matter as IgG, respectively. Each animal was fed two 454-g feedings at 1 a...

Let R be a relation on the domain of a computable structure A. We establish that the existence of an isomorphic copy B ofA such that the image of R (¬R, resp.) is h-simple (h-immune, resp.) relative to B is equivalent to a syntactic condition, termed R is formally h-simple (formally h-immune, resp.) on A.

The contribution of influenza A neuraminidase antibodies to the reaction with whole virus in an enzyme-linked immunosorbent assay (ELISA) was assessed by specific absorption of rabbit hyperimmune sera. Although measurable and independent, the effect of neuraminidase antibodies was less than that of hemagglutinin antibodies. Recombinants with an irrelevant hemagglutinin were used successfully as...

We show that every real low for Demuth randomness is of hyperimmune-free degree.

We isolated and purified to homogeneity a caseinolytic protease from a Nocardia brasiliensis cell extract. Preparative polyacrylamide gel electrophoresis and electroelution were employed for purification. This purified protease was injected in BALB/c mice and induced IgM and IgG anti-protease antibodies. Active immunization of mice with this protease prevented mycetoma development in experiment...

This study aimed to determine the effectiveness of a pregnant mare immunization of a Rhodococcus equi (R. equi) vaccine candidate containing a water-based nanoparticle mineral oil adjuvanted (Montanide IMS 3012) inactive bacterin and virulence-associated protein A (VapA), as well as the administration of anti-R. equi hyperimmune (HI) plasma against R. equi challenge in the mares' foals. The eff...

Agar gel immunodiffusion (AGID) test is a simple and rapid method for the diagnosis of Peste des petits ruminants (PPR) which requires the preparation of potent specific hyperimmune serum. This study deals with the raising of hyperimmune serum against PPR virus in rabbit. Four different inocula included PPR vaccine reconstituted in phosphate buffer saline, PPR antigen suspended in phosphate buf...
