FrogHOLR: Thanks for the extra information about Staph A - I'm keeping it in mind for my Staph A'er.

No problem - I was FREAKED out when my girl came back with it. If you go by the general consensus, your cow is toast. BUT, if you do some hard core searches online you can find plenty of information about how to treat it - - successfully!
Here are a couple of links for those of you that have heifers born to Staph A cows:

"The treatment of heifers known to be at risk for developing Staph. aureus mastitis is advantageous because the expected cure rate is much higher than cure rates obtained when treating infections in lactation. In previous studies, cure rates of Staph. aureus infections in heifers exceeded 90% when treatment was administered prepartum, while cure rates during lactational therapy were approximately 50% (Owens et al. 1991, 1993). In addition, there is no loss of milk, the risk of antibiotic residue in milk at calving is minimal, and future milk production is increased in cows cured of Staph. aureus mastitis (Owens et al., 1991)."

"One study suggested that with Staph. aureus infections, the majority of the infection in heifers are already present by the time of breeding and pregnancy confirmation. Treatments for Staph. aureus infections were equally effective at any of the trimesters of pregnancy. For this reason in herds with Staph. aureus problems, they suggest that heifers could be treated with lactating cow antibiotic preparations at any convenient time from pregnancy confirmation until about 45 days prior to calving and an equally effective cure can be anticipated."
