摘要
黄曲霉菌是自然环境中广泛存在的一种病原微生物,病原菌本身不具备毒性,但是其中繁殖生长过程中会产生黄曲霉毒素,该类毒素会对动物造成严重的毒害作用,引发动物出现严重的中毒症状,造成一定的经济损失。黄曲霉菌的繁殖生长条件比较特殊,主要在高温、潮湿环境下才能繁殖生长,尤其喜欢在玉米、花生和各种谷物中繁殖。黄曲霉菌的种类多种多样,但大部分黄曲霉菌繁殖生长过程中不会产生毒素,只有少部分会产生黄曲霉毒素,该种毒素具有强烈的刺激性,会造成动物的肝脏功能受损,出现严重的中毒症状。如果动物采食了过量含有黄曲霉毒素的饲料,短时间内就会出现急性中毒,危害十分严重,主要表现为中枢神经系统、血管、肝脏严重损伤,对机体的生长发育构成严重威胁。
Aspergillus flavus is a pathogenic microorganism that exists widely in the natural environment.The pathogen itself is not toxic,but it produces aflatoxins during the process of reproduction and growth.This toxin can cause serious poisoning effects in animals and cause serious animal problems.Poisoning brings bad economic losses.The breeding and growth conditions of Aspergillus flavus are quite special.It can only reproduce and grow in high temperature and humid environment.It especially likes to breed in corn,peanuts and various grains.There are many types of Aspergillus flavus,but most of the Aspergillus flavus will not produce toxins during the reproduction and growth process,and only a small part will produce aflatoxin.This toxin is strongly irritating and can damage the liver function of animals.,There was severe poisoning.If an animal eats an excessive amount of feed containing aflatoxin,acute poisoning will occur in a short time,and the threat is very serious,mainly manifested as severe damage to the central nervous system,blood vessels,and liver,which has a serious impact on the growth and development of the body.
