Convenio de cooperación técnica internacional para el control y la erradicación de la fiebre aftosa en la Cuenca del Río de la Plata: logros y perspectivas / International cooperation agreement for the control and eradication of foot-and-mouth disease in the river plate basin: achievements and perspectives

Los Gobiernos de Argentina, Brasil y Uruguay, con la Organización Panamericana de la Salud (OPS), a través del Centro Panamericano de Fiebre Aftosa (PANAFTOSA), en junio de 1987 suscribieron un Convenio de Cooperación Técnica Internacional para el Control y Erradicación de la Fiebre Aftosa en la Cuenca del Río de la Plata. Fue aplicada una estrategia coordinada a través del Proyecto Subregional de Control y Erradicación de la Fiebre Aftosa en la Cuenca del Río de la Plata y ejecutada por los servicios veterinarios de los países con la cooperación técnica de PANAFTOSA. El Convenio comenzó a ejecutar se en 1989 en primera etapa y en una segunda etapa, en el periodo de 1994-1998

Actualizacion de cepas del virus de la fiebre aftosa de importancia epidemiologica en America del Sur / Updating on food-and-mouth disease virus strains of epidemiological importance in South America

The high variability of foot-and-mouth disease, due to genetic recombination and the selective pressure of antibodies in areas of systematic vaccination, is the reason that one strain of virus causes only one epidemic wave in the field. The list of subtypes should therefore be revised periodically to eliminate those which are not longer found in the field. The diagnostic laboratories have to support the control campaigns of the disease by relating antigenically and immunologically the field strains with those used in the production of vaccines. The coverage of the vaccine strains, furthermore, is of great usefulness and interest for vaccines banks. One test which can be recommended for this type of study is the expected percentage of protection (EPP) determined through the serum protection test with sera from vaccinated and revaccinated cattle. An EPP of less than 75 percent with sera from revaccinated cattle is an indication of a low protection level in the field

Caracterización de los ecosistemas de la fiebre aftosa

Esta monografía ha sido preparada en el Centro Panamericano de Fiebre Aftosa tomando como base los estudios sobre el tema realizados por los Servicios Oficiales de Salud Animal de cada uno de los países sudamericanos bajo los auspícios del Programa de Adiestramiento de Profesionales Latinoamericanos en Salud Animal (PROASA), 1982-1985.

Produccion y control de calidad de la vacuna antiaftosa en America del Sur / Production and quality control of foot-and-mouth disease vaccines in South America

In the production of foot-and-mouth disease (FMD) vaccines in South America, the 1950's 60's and part of the 70's were dedicated to creating an infrastructure of production laboratories capable of supplying sufficient quantities of FMD vaccine to meet the needs of the programs. That infrastructure has developed significantly in both the private and official sectors. Most of the South American countries now have qualified FMD vaccines laboratories and advanced production technology. Concomitantly, the infrastructure of the official control laboratoraies was established. The standards of the production laboratories and the vaccines they produce were determined. Quality control that should be applied to the vaccines and the minimum requirements of the protection tests for approval of each series were also defined. At the present the most important step to control and eradicate FMD is to improve the epidemiological surveillance as well as the rational and strategic application of the vaccine, according to the ecosystems of the disease in the Continent
