Due to the obligate nature of Streptococcus agalactiae, its presence in bulk tank milk (BTM) is the exclusive result of shedding of bacteria from infected quarters. Consequently, BTM has a very high specificity, but a low sensitivity for identifying S. agalactiae at the herd level when using traditional milk culture techniques. The objective of this study was to determine the association of the bulk tank culture results with the results of the corresponding cow milk cultures for S. agalactiae in two dairy herds in Iran.
