foot-and-mouth disease is an important viral disease of cloven-hoofed animals. inactivated whole particle virus vaccines are still widely used in prophylactic vaccination campaigns. the choice of adjuvant is a very important factor in enhancing immune responses and the efficacy of inactivated vaccines. montanide isa 61 vg is a new ready-to-use mineral oil-based adjuvant developed by seppic inc....

BACKGROUND Despite the use of vaccines, low-pathogenic (LP) H5N2 influenza viruses have continued to circulate and evolve in chickens in Mexico since 1993, giving rise to multiple genetic variants. Antigenic drift is partially responsible for the failure to control H5N2 influenza by vaccination; the contribution of maternal antibodies to this problem has received less attention. METHODS We in...

BACKGROUND Infection with Goose Reovirus (GRV) can cause serious economic losses in the goose breeding industry. In this study, the GRV allantoic fluid was concentrated and used as an antigen in a formalin-inactivated oil-emulsion vaccine. RESULTS When 6 day-old geese were inoculated, antibodies against GRV became detectable at 6 days post-vaccination, their concentration peaked at 3 weeks. T...

Squalene is a naturally occurring oil which has been used in the development of vaccine adjuvants, such as the oil-in-water emulsion MF59. In past years, by use of noncontrolled and nonvalidated assays, a claim was made that antisqualene antibodies were detectable in the sera of individuals with the so-called Gulf War syndrome. Using a validated enzyme-linked immunosorbent assay for the quantit...

Since 2002, high pathogenicity avian influenza (HPAI) has spread from Asia to Europe and into Africa, causing the largest epizootic of HPAI of the last 50 yr, including infecting domestic and wild waterfowl. Our study was conducted to investigate whether a single vaccination of 7-day-old domestic ducks and geese with inactivated oil emulsion vaccines resulted in protection against HPAI virus ch...

Previous findings, viz. that mice can be successfully immunized against infection with Salmonella dublin with either live or inactivated vaccine, were confirmed. Immunity lasted for at least 12 weeks in mice which had been immunized with inactivated alum-precipitated vaccine. The immunogenicity of inactivated vaccine gradually decreased on storage at 4 degrees C, but this was only detectable if...
