In a herd affected with bovine mastitis, dwarf colony variants of Staphylococcus aureus, auxotrophic for Ca-pantothenate, were isolated from the milk of four cows with mastitis. From one of these cows, a dwarf variant with an unknown metabolic disorder was isolated during the same period. Infections with auxo trophic staphylococci were always chronic and proved to be refractory to anti biotic treatment, though the causative micro-organism was highly susceptible to the drugs used as judged by in vitro tests.
