Samplig rabbit pox aerosols of natural origin.

Natural aerosols of rabbit pox virus produced by groups of infected rabbits were sampled with a slit and Andersen sampler using an adhesive surface sampling technique (Thomas, 1970). The higher rate of successful recoveries of airborne virus compared with a previous report is believed to be due to the much larger volume of air sampled by this technique and to the processing of the whole of the sample collected by the direct addition of a cell suspension to demonstrate the presence of viable virus.
