1277 larger volumes. As cryptosporidiosis is very common in bovine species ordinary colostrum from some cows may be effective. Hyperimmune bovine colostrum is safer than most drugs, which is a consideration when treating debilitated patients, and, should microbial contamination of colostrum pose a problem in immuno-deficient individuals, it could be gamma irradiated without affecting the immuno...

In order to replace the use of mammals for the production of hyperimmune sera and to replace Freund"s complete adjuvant (FCA) with its undesirable side effects, the production and immunological features of IgY were investigated systematically. An important advantage of IgY is that large amounts can easily be extracted from the yolk of immunized laying hens. With special regard to animal welfare...

The main topic of the present work is the relation that a set X is strongly hyperimmune-free (shif) relative to Y . Here X is shif-below Y if and only if for every partial X-recursive function p there is a partial Y -recursive function q such that every a in the domain of p is also in the domain of q and satisfies p(a) < p(q). It is shown that between degrees not above the halting problem this ...

A boy aged 6 months who presented with poor weight gain, diarrhoea, and infection with Pneumocystis carinii was found to have congenital hypogammaglobulinaemia, which did not improve despite monthly treatment with intravenous gammaglobulin. At the age of 3 years and 2 months he developed severe vomiting and diarrhoea due to cryptosporidiosis, which failed to respond to conventional treatment. I...

The early and accurate diagnosis of infectious bursal disease requires known hyperimmune serum against the disease. In this study, an attempt was made to raise anti-infectious bursal disease virus hyperimmune serum in rabbits. The infectious bursal disease (IBD) virus was isolated from field outbreaks, identified, purified, titrated and its infectivity titre was determined in embryonated eggs. ...

Cryptosporidium parvum, a zoonotic Apicomplexan pathogen, causes profound diarrhea, malnutrition, and dehydration in patients with AIDS. A less severe, self-limited disease occurs in immunocompetent individuals, particularly children, animal handlers, and residents of the developing world. Very little is known about the biology of the organism, the pathophysiology of the disease process, or the...

We investigate the relationship between lowness for Schnorr randomness and Schnorr triviality. We show that a real is low for Schnorr randomness if and only if it is Schnorr trivial and hyperimmune free.

As a fundamental experiment for the study on the role of growth hormone in mouse mammary gland, some immunological properties of rabbit antiserum to mouse growth hormone (MGH) were studied. Antiserum was obtained by immunizing New Zealand White male rabbits with MGH preparation extracted from mouse anterior pituitaries. The precipitin titer of the antiserum by precipitin ring test against MGH p...

The rheumatoid factor-like substance (RFLS) induced by hyperimmunization of rabbits with bacteria was consistently and exclusively associated with the macroglobulin fraction of the sera studied. The RFLS is separable from the bulk of serum proteins by zone centrifugation, DEAE cellulose chromatography, and gel filtration. Partially purified preparations of the RFLS were studied by immunoelectro...
