Abstract: | Aleutian disease virus (ADV) can cause pneumonitis in newborn kits up to 3 weeks old. In many cases the pneumonitis is fatal, but can be reduced by treatment with antibodies to ADV. The present report describes antibody therapy in both experimentally infected mink kits and in mink kits from a farm, where an ADV epidemic developed during the whelping period in the spring of 1987. In both cases the antibody treatment was found to have a beneficial effect on the survival rate of the mink kits. One hundred percent survival rate was found for the experimentally infected mink kits. The most pronounced effect for the naturally infected mink was found in the wildtype mink kits, where the death rate was 9.6 % for the antibody treated group versus 16.9 % for the untreated group (p < 0.001). In general the success rate of the gammaglobulin treatment seemed to correlate with the ADV-infection level in the mink sheds. The highest success rate was found in the sheds with the highest ADV-infection level (the standard and wildtype mink), while no effect whatsoever was found for the pearl mink, which were placed in a shed with a low ADV-infection level. |
