Plaque reduction neutralization test for the assay of antibodies against foot-and-mouth disease: brief report
The plaque reduction neutralization (PRN) test for the study of foot-and-mouth disease was described by McVicar et al. (4). They used secondary bovine kidney cell cultures grown for 6 days in disposable plastic plates and ...
Serologycal survey of foot-and-mouth disease in sheep in the Central Valley of Cochabamba, Bolivia
[Summary] A serological survey in the south of the central valley of Cochbamba, Bolivia, showed a high percentage of subclinical infection of foot-and-mouth disease in a sheep population kept in close contact with cattle ...
Foot-and-mouth disease: evaluation of mouse protection test results in relation to cattle immunity
[Introduction] This paper establishes a mre quantitative relationship between the resistance of cattle upon exposure to FMD virus and the results of the MPI than was possible with thw limited data of Cunha et al (2). ...
Oil adjuvanted vaccine: immunological coverage of representative strains of foot-and-mouth disease type A virus in South America
This report shows the results of a cross-immunity test in cattle, using representative field samples as well as those used in vaccine production in South America.
Foot-and-Mouth disease vaccines. I. Comparison of vaccines prepared from virus inactivated with formalin and adsorbed on aluminum hydroxide gel with saponin and virus inactivated with acetylethyleneimine and emulsified with incomplete Freund’s adjuvant
[Introduction] A series of cooperative studies by PIADC and the Pan American Foot-and-Mouth Disease Center (PAFMDC) was undertaken in the isolation units at PAFMDC in Rio de Janeiro in an effort to determine the value of ...
Foot-and-mouth disease: reaction of convalescente pigs to homologous virus exposure
Pigs are more difficult to protect against foot-and-mouth disease (FMD) with inactivated virus vaccines than cattle or sheep (4, 6, 7). Also the results of exposure of convalescent pigs to homologous FMD virus have been ...
Influence of the degree of dispersion in the aqueous phase on the immunogenicity of oil-adjuvanted foot-and-mouth disease vaccine
Both primary emulsion (water-in-oil) and double emulsion (water-in-oil-water) foot-and-mouth disease vaccines with different viscosities produced exellent persistent levels of neutralizing antibodies. The degree of dispersion ...
Foot-and-mouth disease oil-adjuvanted vaccine for pigs. II. Intraperitoneal vaccination of young pigs with double emulsion vaccine
[Introduction] The present paper reports some forther studies on the intraperitoneal vaccination of young pigs with oil adjuvanted double emulsion FMD vaccines containing different quantities of antigen and adjuvant.
Antigenic and immunogenic variability of the foot-and-mouth disease virus
This paper discusses the antigenic and immunogenic classification of FMD virus, intending to suport the disease-control programs. The measures that should de adopeted to reduce the economic impact of the diseases are also ...
Foot-and-mouth disease oil-adjuvanted vaccines for pigs. I. Double emulsion vaccine applied by different routs
[Introduction] In the present young pigs were inoculated with double emulsion oil adjuvanted vaccine using foot-and-mouth disease (FMD) antigens without concentration or purification. Observations were made of the applied ...
