Aflatoxin contamination is an important hazard factor affecting the quality safety and food safety of peanut production, which seriously threatens people's health and safety. In this paper, the background and harmful causes of aflatoxin contamination were analyzed in detail, with attention focusing on its control measures, which has certain guiding significance for the comprehensive control of aflatoxin contamination.

Aflatoxin is the most powerful carcinogen and highly toxic mycotoxin known in nature. It can cause serious toxin pollution to agricultural products, foods and fodders, and is extremely harmful to human and animal health. For aflatoxin pollution, the emphasis is on the control of source, and biological control is favored by scientists because of its advantages of environmental protection and ecological safety. According to the morphology, color and appearance of microbial colonies isolated from maize kernels, 300 bacterial strains were obtained from main maize-producing areas including Tangshan City, Handan City, Shijiazhuang City and Cangzhou City. Two biocontrol bacterial strains(B120 and B65) having a strong control effect on aflatoxins were screened. After identification by molecular biology and physical and chemical properties, the two biocontrol bacterial strains were identified as Bacillus amyloliquefaciens. Their effects on spore germination, mycelial growth and toxin degradation of Aspergillus flavus were investigated. The results showed that strains B120 and B65 could significantly inhibit the spore germination and mycelial growth of A. flavus and reduce aflatoxin production. This study provides a new way to prevent and control the pollution control of aflatoxins in agricultural products.

What is already known about this topic?Brucellosis is one of the world’s most overlooked zoonotic diseases,and humans can easily acquire brucellosis from animals and their *** brucellosis outbreaks are probably attributable to sociocultural factors and compounded by the lack of adequate control measures in sheep and goat rearing *** is added by this report?This is the first identified outbreak caused by Brucella melitensis bv.3 in Jingyang County,Xianyang City,Shaanxi Province.A total of 13 seropositve cases(7 acute patients and 6 asymptomatic persons)were identified from March to May,2020,and the investigation indicated that sheep-to-canine-to-human was the likely transmission *** are the implications for public health practice?Effective control of sheep brucellosis will significantly reduce the risk of human *** should be given to building cooperation between all stakeholders,maintaining epidemiological surveillance to detect human brucellosis at medical centers,and making case reporting mandatory for both veterinary and public health services.

目的对Rothmund-Thomson综合征一家系患者及其家族成员进行基因突变检测。方法收集中国汉族Rothmund-Thomson综合征一家系姐弟2例患者及家族成员临床资料,同时采集其外周血和100例无亲缘关系的健康对照的外周血标本,提取DNA,采用PCR扩增RECQL4基因编码区的全部外显子,应用二代皮肤靶向测序包检测患儿的基因突变,Sanger测序验证。结果 2例患者的RECQL4基因存在2个杂合突变:剪接位点突变c.2886-1G>A和插入突变c.1013_1014insC,两突变分别来自患者父亲和母亲。100例健康对照及患儿兄长均未发现这两种突变。结论 RECQL4基因的剪接位点突变c.2886-1G>A和插入突变c.1013_1014insC可能为引起该家系患者临床表型的病因。
