Image Number K9314-2 In 2001, BARC researchers develop the first transgenic cow, named “Annie,” with resistance to mastitis. The disease is caused by *Staphylococcus aureus* bacteria that destroy milk-secreting cells in the animal’s mammary gland. Mastitis costs U.S. dairy farmers about $1.7 billion annually, including lost milk revenues.  Photo by Scott Bauer.  640 pixels wide: (k9314-2.jpg)   Please visit our Image Gallery
