An in-use study was done to determine the effect of transportation delay on the microflora of clinical specimens collected for microbiological analysis in a 1,000-bed university hospital. Portions of wound, respiratory, and urine specimens were planted for bacterial isolation on the wards immediately after collection. The remainder of each specimen was kept at room temperature without or without holding medium until it was picked up by messengers and taken to the bacteriology laboratory. The results of immediate planting on the ward were compared with those obtained by planting in the laboratory. Alterations in microflora were observed in all three types of specimens after averages of 2 to 4 hours of delay in planting.
在一家拥有1000张床位的大学医院进行了一项使用中的研究，以确定运输延迟对为微生物分析而采集的临床标本微生物群落的影响。伤口、呼吸道和尿液标本的一部分在采集后立即在病房进行细菌分离接种。每个标本的其余部分在室温下保存，有无保存培养基均可，直到被信使取走并送往细菌学实验室。将病房立即接种的结果与在实验室接种获得的结果进行比较。在接种延迟平均2至4小时后，在所有三种类型的标本中均观察到微生物群落的变化。
