Abstract

Three sources of inoculum were examined using TKT medium for detection of Streptococcus agalactiae from a herd of low prevalence of infection. An inoculum of a loopful (0.01 ml) from a bulk milk sample yielded a 3.6% recovery rate. An inoculum of gravity cream from bulk tank samples yielded a 36.5% recovery rate. In a third technique, a loopful of rinsings from the filter pad, through which a complete milking had been filtered, yielded a 62.0% recovery rate.
