Evaluation of the Success of Adoptive Versus Passive Transfer of Immunity Against Trypanosoma Cruzi
… to the above phenomenon, the relative success of passive transfer of sera and adoptive transfer of whole spleen cells was evaluated. Parasitemias and mortality of donor mice maintained at 21°C or 36°C were monitored. The same parameters were monitored in infected recipient mice held at 21°C and …

Behavioral biomarkers for calf health
… and automated) would correlate with measures of passive transfer of immunity (hematocrit; total plasma protein; Immunoglobulins, IgG1 and IgM). Variables collected included: each calf’s first-meal suckling behaviors; automated activity behaviors, and measures of passive transfer of maternal …

Interpretation of the Detection of Antibodies to Sarcocystis neurona in the serum and CSF of young horses
… by the presence of maternal antibodies. Passive transfer of maternal antibodies to S. neurona from seropositive mares to their foals was evaluated. Foals were sampled at birth (presuckle), at 24 hours of age (postsuckle), and at monthly intervals. All foals sampled before suckling were …

Lymphocyte populations and their relationship to cell-mediated immune responses in aflatoxin-treated guinea pigs
… normal skin test responsiveness and weight gain;Passive transfer of delayed type hypersensitivity (DTH) was used to evaluate T lymphocytes or macrophages from aflatoxin-treated guinea pigs. The skin test responses of both nontreated guinea pigs receiving peritoneal exudate cells (PEC) from …

Preconception maternal exposure to Nippostrongylus brasiliensis transfers protection against Nb to her offspring
… infection. This susceptibility is offset by transfer of protective immune components from the mother. Helminth infections are widespread and can have a long lasting influence on host immunity. Children of mothers exposed to helminth infections may display T cell sensitization to endemic …

The transfer of antibody from mother to foetus in the guinea-pig
… on the maternal supply of antibodies. The passive transfer of immunity acquired by the young from its mother can occur before birth, after birth, or both. In man, rabbit and guinea-pig, for example, the transfer of immunity from mother to young occurs entirely prenatally. In the ungulate, …

Immune mechanisms in murine brucellosis: studies with strain RB51, a rough mutant of Brucella abortus
… yet protects mice against smooth strain 2308. Passive transfer experiments using serum and nylon wool enriched T cells obtained from micevaccinated with strain 19 and strain RB51 were carried out. Immune senum from strain 19 vaccinated mice protected against challenge with strain 2308 but not …

Vitamin E Status of Thoroughbred Horses and the Antioxidant Status of Endurance Horses
… of vitamin E to mares demonstrated an increased passive transfer of immunoglobulins to foals. Natural vitamin E has shown a greater bioavailability than synthetic forms, in other species and was tested here at the MARE Center on mares. A greater passive transfer of immunoglobulins was observed …

Effect of Yeast Supplementation During Various Stages of Beef Production
… = 30) were collected to determine the effect on passive transfer. Supplementation ended 22 d after the last calf was born (d 85). Body weight on d 85 was greater (P = 0.01) for YP calves compared with CON. Cows that were supplemented YP had a lower (P = 0.03) neutrophil:lymphocyte at hour 0 and …

An Examination of the Safety and Efficacy of Aripo-Zika as a Zika Virus Vaccine Candidate
… of Aripo-Zika (AZ) vaccination by evaluating passive transfer of maternal antibodies, (ii) the optimal dosage regimen, (iii) anti-vector immunity to the ARPV backbone, and (iv) the effects of boosters on vaccine efficacy. We also evaluated AZ safety via a co-infection study. Our results show a …

Mucosal and systemic immune responses induced by immunisation of cotton rats with recombinant adenoviruses
… while only a slight inhibition was observed by passive transfer of adenovirus-specific antibody. Overall, the results demonstrated that mucosal and systemic immunisation with adenovirus vectors could induce antigen-specific immunity and protection against BHV-1 challenge. The level of …

The development of a humanised mouse model of ANCA associated vasculitis
… and degranulation. Patient derived ANCA was passively transferred into humanised mice that had been primed with GCSF and lipopolysaccharide. Mice were culled 7 days later, but there was no histological or biochemical evidence of disease.<br/>Thus, this work has identified GCSF and …

Developing a Novel, Safe, and Effective Platform for Generating Flavivirus Vaccines
… mediated by neutralizing antibodies based on passive transfer, adoptive transfer, and T-cell depletion studies. However, vaccination studies in Rag1 KO, Tcra KO, and muMt- mice demonstrate the critical role of T-cell responses in developing immunity post-vaccination. In summary, ARPV/ZIKV is a …

Calf intestinal health: assessment and dietary interventions for its improvement
… permeability in response to age, failure of passive transfer, and intestinal location. Analysis of fecal score data indicated that risk for intestinal disease changed hyperbolically from 5 to 35 days with a risk peak around 13 days of age (~0.7), which agrees with previous reports in the …

Biological Evaluation Of The Vaccine Candidate Tf-Ps A1 And A One-Pot Multicomponent Coupling/cyclization For Natural Product Herbicide (±)-Thaxtomin A
… the breast cancer cell line MCF-7. In addition passive transfer of the IgG antibody fraction reduced the tumor of volume (20%) of SCID mice challenged with the MCF-7 cell line when compared to PBS treated controls. These antibodies were also shown to bind the colon cancer cell line HCT-116 and …

Detection and description of influenza a virus transmission in commercial weaned pigs in Illinois, USA
… this study were that piglets have a failure of passive transfer of antibodies from their dams, which contributes to their odds of becoming infected and shedding IAV-S at weaning (OR=36) and during the post-weaning period. This was a hypothesis generating study to determine why the failure of …

Proteomic Analyses of HIV-1 Infected T-cells and the Functional Characterization of Cyclophilin B During HIV-1 Infection
… as well as a nuclear localization signal. Passive transfer experiments showed that secreted CypB did not impact HIV infection. However the deletion of the N-terminus resulted in a pronounced mislocalization of CypB from the ER. Combined, these experiments indicate that intracellular CypB …
