title: Herd studies on coliform mastitis.
abstract: Escherichia coli, Enterobacter aerogenes, and Klebsiella pneumoniae were responsible for 63, 10, and 11 percent, respectively, of 158 coliform organisms recovered from mastitis cases in 8 California herds. The severity and nature of the coliform mastitis problem were found to vary greatly among herds but were characteristic for each of 4 herds studied in detail.
