The validity of a coproantigen ELISA for Echinococcus multilocularis was evaluated by comparison of three diagnostic methods; autopsy, egg examination and the ELISA. Of 71 foxes, 39 were found to be infected with the cestode at autopsy. The overall mean of worm burdens was 3,451, but the number varied (1-34,522). The ELISA could detect 94.9% (37/39) of the worm positives and there were no false-positives. Two false-negatives were infected with 1 and 4 cestodes, whereas 3 cases with similar worm burdens (2, 4 and 6 worms) were diagnosed as positives. This indicates the detection limit of the assay may be equivalent to less than 10 (in the worm burden). On the other hand, egg examination showed low sensitivity (43.6%, 17/39). These results suggest the ELISA has a potential to replace for the conventional methods

Studying of palatability of bait blisters applied for oral immunization of wild carnivores against rabies was realized in the conditions of the Republic of Belarus by an example of foxes which were administrated with liquid viral vaccines against rabies. Foxes were divided into 5 groups with 8 animals in each. Animals of the first group were immunized with a liquid viral vaccine in blister baits Lisvulpen-VBF which was produced from an attenuate strain of rabies virus SAD-BERN (Belarus). Animals of the second group were immunized with liquid viral vaccine Belvak TM BP produced from the cultural living strain KMIEhV-V101 (Belarus). Animals of the rest three groups were immunized with liquid viral vaccine in blister baits which was produced from a modified strain of a fixed attenuate rabies virus KMIEV-94. Foxes of the forth group were additionally fed with ascorbic acid with baits in the doze of 0,1 g, and foxes of the fifth group were fed with 5 ml immune response modifier Nuklevit. All mentioned blister baits were studied in accordance with the following parameters: bait flavor and attraction to animals; form and size of bait; bait consistency; blister and its size in relation to bait; palatability of bait; degree of damage of bait containing a vaccine; quantity vaccine which was got into animal oral cavity; postvaccinal complication. Palatability of liquid viral vaccines in blister baits Lisvulpen-VBF was 96%, Belvak TM BP - 94%, KMIEV-94 - 80%
