Three surveys were conducted during November 1995 and March and May 1996 to compare the use of double-strength skim milk (wet) or no transport media (dry) drag swabs for the detection of salmonellae in 10 broiler houses. Salmonellae were isolated from 57 of 120 individual wet drag-swab samples, compared with 21 of 120 dry drag-swab samples. Furthermore, Salmonella was detected at a higher frequency with wet drag swabs (66.7%) than with dry drag swabs (40%) when compared on an individual growout house basis. A total of seven different serotypes were isolated from the 10 broiler houses. Although double-strength skim milk drag swabs are more labor intensive than dry drag swabs, double-strength skim milk drag swabs are more efficient for detecting Salmonella than are dry drag swabs with no transport media.
1995年11月以及1996年3月和5月期间进行了三项调查，以比较使用双倍强度脱脂奶（湿）或无运输培养基（干）的拖拭子对10个肉鸡舍中的沙门氏菌进行检测的情况。在120个单独的湿拖拭子样本中，有57个分离出了沙门氏菌，相比之下，120个干拖拭子样本中有21个分离出了沙门氏菌。此外，按单个育成舍计算，湿拖拭子检测出沙门氏菌的频率（66.7%）高于干拖拭子（40%）。从10个肉鸡舍中共分离出七种不同的血清型。尽管双倍强度脱脂奶拖拭子比干拖拭子需要更多的人力，但双倍强度脱脂奶拖拭子在检测沙门氏菌方面比无运输培养基的干拖拭子更有效。
