HI, I got question for my homework and it goes like this. i got a culture of s.aureus that been incubated with AB disks and that's what came out: 1. benzilpenicilin 10mm [13-19] - resistant 2. vancomycin 14mm [11-12] - sensitive 3. ciprofloxacin 23mm [15-21] - sensitive now, the culture showed sensitivity for the 2nd and the 3rd AB but both of them are +2mm. so which one of those should i chose and what are the parameters that i should evaluate? thanks!
