Objective To evaluate a new screened strain of bacteria AC04 found in the soil of long-term planting of Chinese wolfberry which can efficiently degrade the pesticide acetamiprid using rodent acute toxicity models. Methods The extracted fluid of bacteria was given to mice for acute toxicity experiment by ig. The rats were fed with wolfberry sprayed by the bacterial suspension for 30 d. Results The acute oral toxicity tests showed the tested mice behaving and eating normal, without poisoning and death. At the end of the observation, the mice were dissected and the major organs showed no abnormalities. In the experiments of rats fed for 30 d, the appearance of experimental rats, as well as the behavior, body weight, and blood indicators showed normal, without obvious symptoms or adverse reactions. Conclusion The research showed that this strain of bacteria was harmless to the experimental animals.
