Abstract
Twenty bovine udder quarters colonized with C. bovi SR6 and 20 uncolonized quarters were challenged by inoculation of S. aureus Newbold 305 (ATCC 29740) in the teat cistern. The percentage of infection in quarters colonized with C. bovis (50%) was significantly lower than that in controls (100%). By similar challenge no significant difference was observed between the percentage of infection with S. agalactiae ATCC 27956 in 33 quarters colonized with C. bovis (70%) compared to 33 controls (87.9%). A total of 37 quarters colonized with C. bois and 37 control quarters were challenged with S. aureus Newbould 305 (ATCC 29740) and Maxi (ATCC 27543) and S. agalactiae orifice. The percentage of teat ducts colonized with C. bovis which became infected with either pathogen was not different from that for controls.This publication has 18 references indexed in Scilit:
