High tetracycline resistance alarm in Iran

The bacterial resistance to antibiotics have become a worldwide health concern. Tetracycline has not been excluded, its low price and broad-spectrum antimicrobial agent activity have led to high consumption in the aspects of health care and food hygiene. Escherichia coli is an indicator of bacterial species in food, human, and livestock health, which has led to a good model for studying antibiotic resistance. The purpose of this study was to evaluate the E.coli strains tetracycline resistance status in food, human and animal populations of Iran up to 2018. The discussion about food is important as a common area of human, animal populations and environment and also as one of the resistant strain transmission factors. A survey of the study’s results showed that the average resistance to Tetracycline in poultry with Colibacillosis 86/74 percent, human isolates 64/11 percent and food isolates are 60/9 percent. Regarding this level of resistance, it is recommended that the distribution and consumption of tetracycline in Iran should be discontinue for a period of time in order to reduce the population of resistant strains by other antibiotics and methods. The molecular epidemiology and affecting factors of resistance creation should be evaluate.
