staphyloc

A team of researchers from Arizona bought meat and poultry in five cities across the United States, tested them for bacteria, and found this: 47 percent of the samples contained the very common pathogen Staphylococcus aureus, and 96 percent of those isolates were resistant to at least one antibiotic. Of more concern: 52 percent of those staph isolates were resistant to at least three antibiotics that are commonly used in both veterinary and human medicine… 

The antibiotics to which the staph was resistant included: penicillin and ampicillin; erythromycin; tetracycline; oxacillin, the more modern form of the drug methicillin; the drug combination quinupristin/dalfopristin, known as Synercid; the fluoroquinolones levofloxacin (Levaquin) and ciprofloxacin (Cipro); and the last-resort drugs for very serious staph infections vancomycin and daptomycin. One staph isolate was resistant to nine different antibiotics.
