An experimental allergic neuritis-like disease was induced in rabbits 3 to 8 weeks after injection with large doses of influenza vaccines mixed with gangliosides, cholesterol, and Freund complete adjuvant. The inclusion of gangliosides was essential to induce the experimental allergic neuritis-like disease. In trials with six different lots of vaccine, both swine influenza and non-swine influen...

For many decades, mineral oils with or without dried mycobacteria, i.e. Complete and Incomplete Freund ́s Adjuvant, have been the most commonly used immune adjuvants for experimental work. Later on, better defined hydrocarbon oils such as pristane (2,6,10,14-tetramethylpentadecane), squalene (2,6,10,15,19,23-hexamethyl-2,6,10,14,18,22-tetracosa-hexane), or hexadecane have emerged and partially r...

The success of many vaccines relies on their association with selected adjuvants in order to increase their immunogenicity and ensure long-term protection. Propolis is a natural compounds, are mostly known for their immunostimulatory  properties. In this study the adjuvant effects of propolis in combination with formalin-killed A. hydrophila vaccine in Common carp (Cyprinus carpio) were evaluat...

partially fed (4 -5 days) h .a. anatolicum (iranian isolate) female adult ticks were used for preparation of antigens of midgut which are, the gut supernate antigen (gs), gut membrane antigen (gm), triton extracted gut membrane antigen ( tx-gm ) and sodium dodecyl sulphate treated triton extracted gut membrane antigen (sds-tx-gm). the new zealand white rabbits were immunized with gs, gm, tx- gm...

Antisera were produced by inoculation of mycoplasma cells grown in PPLO broth supplemented with rabbit serum alone or rabbit serum plus Freund complete or incomplete adjuvant. By using an enzyme-linked immunosorbent assay, immunoglobulin G antibodies to cholesterol were detected in antisera to mycoplasmas (Mycoplasma salivarium ATCC 23064, M. orale ATCC 15539, M. buccale IID 802, M. faucium IID...

Disseminated encephalomyelitis was readily induced in mice of the Swiss strain by means of repeated intramuscular and subcutaneous injections of apparently normal mouse brain mixed with an adjuvant. The latter consisted of autoclaved virulent tubercle bacilli and heavy liquid petrolatum, a modification of the Freund adjuvant. The syndrome and the histopathological picture of the induced malady ...

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...

A chemically synthesized copy (S-CB7) of a fragment (35 amino acid residues) of type 24 streptococcal M protein was covalently linked to polylysine with carbodiimide and injected subcutaneously into rabbits without adjuvant. Although the primary immune responses as measured by enzyme-linked immunosorbent assays at biweekly intervals were weak, the secondary responses as measured by both enzyme-...

Excretory-secretory products (ESP) of myiasis producing agents are involved in nutrition and development of larvae and are often immunogens. This study was carried out in order to define the antigenicity, the immunogenicity of Oestrus ovis ESP and the role of sheep immune response to ESP. Twenty-four six to eight month old female lambs were randomly allocated into two groups. The first one was ...

A 68-kilodalton (kd) outer membrane protein antigen of Bordetella bronchiseptica has been identified by using monoclonal antibodies that recognized two nonoverlapping determinants. Antibody BB05 also reacted with homologous proteins from Bordetella pertussis and Bordetella parapertussis but not with another 12 organisms from various bacterial genera. Passive injection of BB05 antibody protected...
