1. Young ovine death during hyperimmunization: crotalic envenomation or copper toxicosis?
The unfavorable evolution of a young ovine during hyperimmunization process with Crotalus durissus terrificus venom was investigated in order to differentiate its origin between ophidic envenomation and copper toxicosis. Clinical, laboratory, necroscopic and histological exams as well as evaluation and measurement of heavy metals (copper) in the kidneys and

2. Laboratory evaluation of young ovines inoculated with natural or 60co-irradiated Crotalus durissus terrificus venom during hyperimmunization process
Laboratory profile of young ovines was studied in order to evaluate and compare their antiserum production from natural and Cobalt-60 irradiated Crotalus durissus terrificus (C.d.t.) venoms. The parameters analyzed included complete blood count, and urea, creatinine, aspartate aminotransferase, total proteins, albumin and globulin serum measurements. Three g

3. Immunological assessment of mice hyperimmunized with native and Cobalt-60-irradiated Bothrops venoms
ELISA was used to evaluate, accompany, and compare the humoral immune response of Swiss mice during hyperimmunization with native and Cobalt-60-irradiated (60Co) venoms of Bothrops jararaca, Bothrops jararacussu and Bothrops moojeni. Potency and neutralization were evaluated by in vitro challenges. After hyperimmunization, immunity was observed by in vivo ch

4. Immunization with native and cobalt 60-irradiated Crotalus durissus terrificus venom in swiss mice: assessment of the neutralizing potency of antisera
ELISA was used to evaluate, follow, and compare the humoral immune response of Swiss mice during hyperimmunization with natural and Cobalt 60-irradiated (60Co) Crotalus durissus terrificus venom. Potency and neutralization were evaluated by in vitro challenges. After hyperimmunization, immunity was observed by "in vivo" challenge and the side effects were as

5. Variation of blood profile during the hyperimmunization and after bleeding and plasmapherese in equine serum hyperimune anticrotalics production / Variações da crase sangüínea durante a hiperimunização e após sangria e plasmaferese em eqüinos de produção de soro hiperimune anti-crotálico
Para o estabelecimento do quadro sangüíneo de eqüinos durante a hiperimunização para produção de soro hiperimune anti-crotálico e após as sangrias de produção e a plasmaferese, foram utilizados 20 animais, obedecendo as normas do protocolo de hiperimunização do Instituto Butantan. As amostras foram colhidas antes das inoculações do antígeno (

6. STUDIES OF DIPHTHERIA ANTITOXIN IN RHEUMATIC FEVER SUBJECTS: ANALYSIS OF REACTIONS TO THE SCHICK TEST AND OF ANTITOXIN RESPONSES FOLLOWING HYPERIMMUNIZATION WITH DIPHTHERIA TOXOID

7. Enzyme-Linked Immunosorbent Assay for Detecting Herpesvirus Exposure in Mediterranean Tortoises (Spur-Thighed Tortoise [Testudo graeca] and Hermann's Tortoise [Testudo hermanni])†
An enzyme-linked immunosorbent assay (ELISA) was developed for the detection of antibodies to a herpesvirus associated with an upper respiratory tract disease in Mediterranean tortoises [spur-thighed tortoise (Testudo graeca) and Hermann's tortoise (Testudo hermanni)]. This serodiagnostic test was validated through a hyperimmunization study. The mean of the

8. Sudden unexplained death in infancy and hyperimmunization
Serum immunoglobulin concentrations, predominantly IgM, were raised in 72% of 39 sudden infant death cases, consistent with a state of prolonged or repeated antigenic stimulation.

9. Homogeneous Antibody Elicited with Dinitrophenyl-Gramicidin-S
Rabbit antibody to dinitrophenyl hapten has been elicited by hyperimmunization with a bifunctional cyclic decapeptide antigen, di-dinitrophenyl-gramicidin-S. Examination of the induced antibody by isoelectric focusing, and Sipsian analysis of the haptenbinding data, demonstrated that di-dinitrophenyl-gramicidin-S was capable of stimulating and maintaining th

10. Human auto-antiidiotypes regulating T cell-mediated reactivity to tetanus toxoid.
While investigating the effect on B cells of repetitive in vivo immunization with tetanus toxoid (TT), we observed the subsequent development of specific anergy for T cell delayed hypersensitivity (DTH) to TT. This appeared approximately 35 d after a series of five booster immunizations. Concurrently, in vitro T cell blastogenic responses were preserved. Ser

11. Effect of Vaccine, Route, and Schedule on Antibody Response of Rabbits to Pasteurella tularensis
The response of the rabbit to viable or killed whole-cell Pasteurella tularensis vaccines was studied. The most practical preparation for the production of anti-P. tularensis antibodies was viable organisms of the live vaccine strain (LVS). The intravenous route of administration proved superior to either the subcutaneous or intradermal routes, and incorpora

12. Identification of cross-reactive antigens between Mycoplasma pulmonis and Mycoplasma arthritidis.
Serological cross-reactivity between Mycoplasma pulmonis and Mycoplasma arthritidis was investigated by enzyme-linked immunosorbent assay, immunoanalysis of electrophoretic blots, and protein A immunoprecipitation reactions. The results demonstrate that one-way cross-reactivity was present in both hyperimmunized and naturally infected rats and that the predo
