abstract = {Mastitis is a common disease of lactating cows and is caused by several different types of bacteria
including Nocardia farcinica. The objective of the current study is to demonstrate pathology clinical
manifestations of experimental mastitis in dairy cows induced by field isolates of Nocardia farcinica. The
infection was done by intramammary infusion in two healthy lactating dairy cows using two field isolates of
N. farcinica. The infected animals were examined periodically for clinical signs and laboratory profiles. The first
cow showed typical clinical signs of acute Nocardia mastitis with granulomatous reaction whereas the second
cow showed sub-acute clinical mastitis. While the first cow died within a few days post infection, the second
cow survived but didnt respond to standard mastitis treatment. Treatments of the experimentally induced
mastitis with Neomastipra® and Gentamast® failed to cure the infection and after the withdrawal period of both
drugs Nocardia continued to shed from udder. Clinical isolate of Nocardia farcinica caused mastitis that was
either subacute/irresponsive to treatment or fatal peracute leading to death.}
