[Antibiotic sensitivity testing on the automatic MS-2. Use of antibiotic discs from 3 different sources].
The MS-2 automate for antibiotic susceptibility testing was experimented under conditions different from those recommended by the manufacturer, namely using antibiotic discs from different firms. Susceptibility of eight Enterobacteriaceae strains recovered from urine to nine antibiotics borne by discs from three different firms was tested. Results obtained with the different brands of discs were dissonant in less than 7% of cases (major and minor disagreements compounded). Major discrepancies ranged from 2.8 to 4.2% according to the origin of discs. The reproducibility study found consistent results in 87.5% of cases, and satisfactory results (i.e. minor discrepancies excluded) in 93.5% of cases.
