The normal flora of cockroaches (Periplaneta americana) was determined over a period of 24 days prior to substituting water with 1% Formalin for drinking water. During the first 4 days of treatment the normal flora was significantly reduced and by the fifth day, when the cockroaches became diarrhoeic, no bacteria, fungi, or viruses could be detected by the methods used.
在用1%福尔马林替代饮用水之前的24天内,对美洲大蠊的正常菌群进行了测定。在处理的前4天,正常菌群显著减少,到第5天蟑螂出现腹泻时,使用的方法检测不到任何细菌、真菌或病毒。
