Feline calicivirus (FCV) strains can show significant antigenic variation when tested for cross-reactivity with antisera produced against other FCV strains. Previous work has demonstrated the presence of hypervariable amino acid sequences in the capsid protein of FCV (designated regions C and E) that were postulated to constitute the major antigenic determinants of the virus. To examine the inv...
Background: The UL31 protein of herpes simplex virus 1 (HSV-1) plays an important role in the HSV-1 replication, however, its pinpoint functions in the life cycle of the virus have yet to be adequately elucidated. Objectives: An antiserum specific for detecting HSV-1 UL31 was prepared as the foundation for future research on the role of UL31 in the course...
We have measured the production by (C57 x CBA)F(1) mice of hapten-binding antibody in response to a standard dose of 50 microg of alum-precipitated NIP(12)-CG and the influence on this response of the prior administration of hyperimmune antisera raised against the homologous conjugate, the carrier globulin alone, the hapten conjugated to a non-cross-reactive carrier (NIP(4)-OA), or a related ha...
Sustained infection of HeLa cells by Coxsackie B3 virus, dependent on presence of viral inhibitor in culture medium, was achieved. Persistent treatment of carrier cultures with anti-Coxsackie B3 hyperimmune monkey serum eventually eliminated virus from carrier cultures indicating that a lysogenic virus-cell relationship was not operative. Free virus was produced continuously by carrier cultures...
The sensitivity of an enzyme-linked immunosorbent assay (ELISA) to detect pure native Escherichia coli heat-stable toxin (ST) and to identify ST-producing strains among clinical isolates was determined. Two synthetically produced ST preparations were used to raise hyperimmune antisera in rabbits and goats: ST(S), which has the same antigenicity as native ST; and ST(C), which is 15-fold more imm...
Four monoclonal antibodies were raised against the lipopolysaccharide of Rhizobium leguminosarum bv. phaseoli CFN42 grown in tryptone and yeast extract. Two of these antibodies reacted relatively weakly with the lipopolysaccharide of bacteroids of this strain isolated from bean nodules. Growth ex planta of strain CFN42 at low pH, high temperature, low phosphate, or low oxygen concentration also...
Endotoxaemia is a major cause of equine morbidity, and plasma from horses immunised against Escherichia coli is used in its treatment. The aim of this study was to determine the effects of hyperimmune plasma on the clinical and leukocyte responses, including production and activity of TNFα, in an in vivo endotoxin challenge model. Pre-treatment with hyperimmune equine plasma had no significant ...
background: objective: the objective of this study was to evaluate the effect of rabbit antiserum to es cells on mouse preimplantation embryo development and chimera production. materials and methods: mouse 4-cell embryos were matured in vitro at 37.5 o c, in humidified 5% co 2 atmosphere for 12-36 h. the embryos were cultured in ksom medium with or without antiserum for 12-36 h. the ratios...
Plasvacc Australia (Plasvacc) 6066 Cunningham Hwy Kalbar Queensland Australia 4309 61-7-54637600 Objectives – To develop an effective Escherichia coli (E. coli) vaccine that engenders a strong and measurable humoral response in canine plasma donors. To develop an assay to determine potency of plasma derived from vaccinated canine donors. To determine efficacy of hyperimmune plasma to E. coli in...
