Abstract
A clinical evaluation of three commercially available transport systems (Anaerobic Specimen Collector, Becton-Dickenson; Anaswab, Scott Laboratories; and Trans- Cul, Wampole) was done, using as subjects 75 patients suspected of having infections. Holding times were purposely varied and ranged from 30 min to 48 hours. Totals of 22 aerobic species and 15 anaerobic species were isolated. There was essentially no difference among the three systems in the recoveries of aerobic or anaerobic organisms. Discrepancies appeared to be related to the order of collection and amount of clinical material available for culture. Time delay from collection to plating did not affect the recovery of aerobes or anaerobes. The three systems performed equally in the recovery of clinically significant pathogens from purulent clinical material.
