Sample text

Specific zone diameter interpretive criteria used when testing N. gonorrhoeae are listed in M1009 Table 2F. Disk diffusion testing of N. gonorrhoeae with other agents is not recommended. NOTE: N. 17 However, β-lactamase tests (see Section 13) are faster than disk diffusion tests and are therefore preferred for recognition of this plasmid-mediated penicillin resistance. N. gonorrhoeae with plasmid-mediated resistance to tetracycline also has zones of inhibition (30-μg tetracycline disks) of ≤ 19 mm.

Equipment – not functioning properly or out of calibration (eg, pipettes). 1 Immediate Corrective Action If the reason for the out-of-control result cannot be identified, corrective action is required as follows. • • Test the out-of-control antimicrobial agent/organism combination on the day the error is observed and/or as soon as a new working culture or subculture is available. Monitor for a total of five consecutive test days. Document all results. – If all five zone diameter measurements for the antimicrobial agent/organism combination are within the acceptable ranges, as defined in M1009 Table 3, no additional corrective action is necessary.

24 hours of incubation are required before reporting as susceptible; other agents can be read and reported at 16 to 18 hours. Use transmitted light (plate held up to light) to examine the oxacillin and vancomycin zones for light growth of resistant colonies within apparent zones of inhibition. Any discernable growth within the zone of inhibition is indicative of oxacillin or vancomycin resistance. , read the zone diameters with reflected, not transmitted, light. , read the zone diameters with transmitted light.
