This is a true case study. A woman kept coming to the doctor with a MRSA (multidrug resistant Staphylococcus aureus) infection. The doctor was able to cure her because it was sensitive to an antibiotic. It also did not develop further drug resistance over time, suggesting that the woman was being re-exposed to a source of infection that was not being treated with the antibiotic. Upon investigation, her children and house were unaffected, but her husband and bed had low numbers of MRSA, probably from contact with the woman or source. Upon learning that her cat slept with her, high numbers of MRSA were found in its fur, skin, and mouth. The cat had been re-exposing her to MRSA. The moral is it is dangerous sleeping with your kitty. What can be done to ensure that there are no further cases of MRSA in this family? (Hint, who and what should be treated, how, and what should the treatment be?).
