Toxicology Researchwere delighted to sponsor a poster prize at the 2nd Eco-toxicology conference,which took place from the 25th – 28th April 2015 in Xiamen,中国Many congratulations to Liang-ying He (Guangzhou Institute of Geo新利手机客户端chemistry,Chinese Academy of 新利手机客户端Sciences) for winning this prize with their poster entitiled: "Dissemination of Antibiotic Resistance Genes in Representative Broiler Feedlots Environments: Identification of Indicator ARGs and Correlations with Environmental Variables".
"Broiler feedlots may represent an important source of antibiotic resistance genes (ARGs) in the environment.However,the prevalence and dissemination mechanisms of various types of ARGs in the environment of broiler feedlots have not previously been identified.We examined the occurrence,abundance and variation of ARGs conferring resistance to chloramphenicols,sulfonamides and tetracyclines in the environments of two representative types of broiler feedlots (free range and indoor) and assessed their dissemination mechanisms.Horizontal gene transfer and co-selection were found to play important roles in ARG dissemination in the environment.fexA,sul1andtetWcould be reliable indicator genes to surrogate anthropogenic sources of ARGs in boiler feedlots.The distribution and transportation of ARGs from the boiler feedlots to the receiving environments were correlated with environmental variables.The findings highlight the contribution of some chemicals such as antibiotics and metals to the development of ARGs in broiler feedlots environments;and the observed ARG dissemination mechanism in the broiler feedlots facilitates the development of effective mitigation measures."
Many congratulations to Liang-ying on receiving your prize
