چکیده

A serological survey was carried out on French cattle to establish a reference pattern of residual vaccine antibodies and non-specific reactions against the foot-and-mouth disease virus 6 years after the ban on vaccination and in the absence of any foot-and-mouth disease outbreak. Most of the multi-vaccinated cattle still displayed high titres of antibodies and up to 50% of those which had received a single injection still had antibodies. Non-specific reactors were also recorded among animals born during and after 1991. Most of them displayed low titres close to the threshold. Sheep were also tested and, as for cattle, 4.6% of non-specific reactors were recorded, with titres close to the threshold for two-thirds of them. As part of these animals have been resampled and retested, sera revealed negative confirming that these animals are true non-specific reactors. Serological testing as a mean of FMD control should take these facts into account.

Multiplication of an attenuated RV11 strain (type SAT12) of foot-and-mouth disease virus in sheep.

Investigations at Pirbright have shown that strains of virus which a re attenuated and immunogenic for cattle were also attenuated for sheep and produced a good immune response (Report, 1964). The work of Geering & Pay (1963) included studies with the RV11 vaccine strain, which at a high dosage level caused no post vaccinal reactions in a group of twenty four-month old lambs. Examination of the...
