Colonization with Corynebacterium bovis was established in 59 of 64 (92%), 58 of 59 (98%) and 19 of 34 (56%) of uninfected bovine mammary quarters following inoculation of 83.3 X 10(4) colony-forming units (CFU) of the organism into the teat cistern, 4.7 X 10(3) CFU 5 mm into the teat duct or by exposure of the teat orifice to a milk culture containing 1.6 X 10(7) CFU/mL respectively. Mean somatic cell counts for foremilk samples from 122 quarters were significantly higher after colonization with C. bovis (145,900/mL) compared to before exposure (130,900/mL).
在将83.3×10⁴个该菌的菌落形成单位（CFU）接种到乳头池、将4.7×10³CFU接种到乳头管5毫米深处或分别使乳头开口暴露于含有1.6×10⁷CFU/mL的乳汁培养物后，未感染的牛乳腺腺叶中，牛棒状杆菌定殖率分别为64个中的59个（92%）、59个中的58个（98%）和34个中的19个（56%）。与暴露前（130,900/mL）相比，122个腺叶的前乳样品在牛棒状杆菌定殖后的平均体细胞计数显著更高（145,900/mL）。
