This paper discribes the results of the protection status of cattle against Foot-and-
Mouth Disease (FMD) found during the 1978 to 1985 period. One of the vaccination
cycles was considered for each year, and a statistical representative random sample
was calculated for both, young and adult cattle. Animals were bled at day 90 postvaccination and neutralizing antibody titers against FMD types A and 0 were assayed
by neutralization test in microtiter plates, using BHK21 cells. The value of 1.5 log
was considered to discriminate protected from unprotected cattle. During the analyzed
period, in young cattle, the percentages of protection against the virus type A
ranged from 25.6 to 64.4%, and against the type 0 from 27.9 to 74.2%. The estimated
percentages of protection in adult cattle, ranged from 23.1 to 87.7% against the virus
type A and from 42.8 to 88.8% against the type 0. The estimated percentages of
protection found in adult cattle were, in most of the years, higher (P < 0.05) than
those found in young cattle. In the latter category, the inmune response against the
virus type 0 was higher than that against the type A. These differences were statistically
significant (P < 0.05) in 1979, 1980, 1981 and 1982. From the above results
a satisfactory protection status against FMD was deduced, specially since 1980
which has been reflected in a remarkable reduction of FMD outbreaks in this region.
Besides, it was confirmed the efficacy of massive and systematic vaccination procedures,
complemented by other actions such as control of cattle movement and
severe epidemiologic surveillance. |

Se describen los resultados de la evaluación continuada del estado de protección contra fiebre aftosa (F.A.) en la población bovina del Urabá antioqueño, durante 1978 a 1985. Para cada año se consideró uno de los ciclos de vacunación y se determinó una muestra estadísticamente representativa de bovinos jóvenes y adultos. Estos fueron sangrados a los 90 días post-vacunación y sus títulos de anticuerpos contra los virus tipos A y O evaluados mediante la técnica de seroneutralización en placa, utilizando células BHK sub 21. Se consideró el valor 1.5 log como título discriminante entre protección y no protección. Durante el período analizado, en los bovinos jóvenes los valores estimados de protección contra el virus tipo A oscilaron entre 25.6 y 64.4 por ciento y contra el tipo O, entre 27.9 y 74.2 por ciento. En los adultos, los valores estimados de protección fluctuaron entre 23.1 y 87.7 por ciento para el virus tipo A y entre 42.8 y 88.8 por ciento para el virus tipo O. El procentaje estimado de bovinos adultos protegidos contra F.A. fue en la mayoría de los años superior (P menor que 0.05) al encontrado en los jóvenes, en los cuales la respuesta inmune fue mayor para el virus tipo O que para el tipo A, siendo la diferencia estadísticamente significativa (P menor que 0.05) en los años 1979, 1980, 1981 y 1982. De los resultados se dedujo que la protección contra F.A. fue satisfactoria, especialmente a partir de 1980, reflejada en una disminución notoria del número de focos en la región, lo cual confirma la eficacia de los programas masivos y sistemáticos de vacunación, complementados con medidas de control de movilización de animales y una drástica vigilancia epidemiológica.
