FMD VIRUS TYPE A22 IN CATTLE EPIDEMIOLOGY OF FOOT-AND-MOUTH
DISEASE (IN THE UKRAINE) IN RELATION TO IMMUNIZATION.
(Epizootichnii protses ta imunizatsiya silskogospodarskikh
tvarin pri yashchuri).

VETERINAIIA (KIEV), in Russian, Vol. 47, 1978, pp. 36-38.

(Article by Poluliakh, V.I.).

The intensity of foot-and-mouth disease epizootics and their
Spread have considerably decreased since the introduction of
specific active immunization (H. Rerer, 1957; 1958; F. C. Salces,
1967; . W. Golthals, 1968; J. Borsella, 1970; A. A. Boyko, 1970,
et al.).

Owing to immunization, the course of the foot-and-mouth
disease epizootics has changed and their liquidation has become
easy.

The analysis of the statistical material available on the
foot-and-mouth disease epizootics that broke out in Ukraine during
1965 - 1966 and were caused by the virus of type A22, allowed us
to evaluate objectively how the vaccination of cattle influenced
the course of the epizootic process as a whole as well as efficacy
of the means used in liquidating an epizootic that began in October-
December, 1965.

According to the course assumed by the epizootic in each of
the regions of the republic and according to the general foot-and-
mouth disease vaccinations carried out in cattle we have divided
all the regions into three zones and analyzed them separately.

The first zone included 10 districts in which the foot-and-
mouth disease epizootics broke out in October-November, 1965. In
the initial period of the outbreak the cattle were almost not being
vaccinated (because of vaccine shortage) and the fight against the
disease was limited to the use of veterinary-cum-sanitary as well
