[ 1 ] - Prevalence of antibiotic resistant genes in selected activated sludge processes in Isfahan Province, Iran

Wastewater treatment plants are one of the main sources of dissemination of antibiotic resistance genes (ARGs) into the environment. The present study was conducted to determine the prevalence and removal of ARGs in different wastewater treatment processes. A total of 36 samples from raw and final effluent of different activated sludge processes were collected and analyzed. Molecular analysis w...

[ 2 ] - چرخش محیطی ژن‌های کُدکننده مقاومت آنتی‌بیوتیکی: یک مرور سیستماتیک

باکتری‌ها و ژن‌های مقاوم به آنتی‌بیوتیک از طرق مختلف به محیط‌ زیست وارد می‌شوند. انتشار این عوامل به محیط­ زیست باعث افزایش نگرانی ­های مرتبط با سلامت عمومی شده است. در مقاله حاضر ژن­ های کُدکننده مقاومت آنتی­بیوتیکی در منابع محیطی مورد بررسی قرار گرفته است. در این مرور سیستماتیک داده‌ها از 1294 مقالـه، 39 مقالـه از منابـع اطلاعاتـی معتبـر شامـل؛ Science Direct، PubMed،Google Scholar و SID استخر...

[ 3 ] - پایش تنوع ژنهای کد کننده مقاومت آنتی بیوتیکی در فاضلاب های شهری

Background and objective: Wastewater treatment plants are important hotspots for the spread of antibiotic resistance genes to the environment.  The aim of this study identification of relevant antibiotic resistance genes in raw and final effluent of municipal wastewater treatment and also determination of effects of different wastewater treatment process on removal/reduction of these pollu...

[ 4 ] - Simple method for extracting gold from electrical and electronic wastes using hydrometallurgical process

 Background: This research studied the feasibility of a simple method for extracting gold from central processing units (CPUs) of computer circuit boards without solvent. Methods: Ceramic and composite CPUs of computer circuit boards were used. Gold was extracted using a hydrometallurgical method in six stages: grinding of CPUs, leaching in nitric acid, leaching in aqua regia, remov...

[ 5 ] - Identification of clinically antibiotic resistant genes Aac(3)-IIa and Aac(6’)-Ib in wastewater samples by multiplex PCR

Background: Aminoglycoside antibiotics are widely used in medical centers, particularly to treat infections. The resistance developed against these agents is a huge concern in health care. A number of researchers have reported that hospital and municipal wastewaters are among the most important dissemination sources of these agent into the environment. Some, however, do not agree with this opin...
