Abstract
Escherichia coli is from gram-negative cocobacillis family of Entrobactriaceae, and is one of the most prevalent bacteria factors which separated from human infections. This study is implemented with the aim of drug resistance pattern of Escherichia coli bacteria in Ali ebn Abitaleb laboratory of Rafsanjan in 2015 and 2016. This descriptive-sectional study was performed on all of positive culture samples considering Escherichia coli in laboratory of Ali ebne Abitaleb hospital of Rafsanjan. In the time interval of performing study in 2015 and 2016, a number of 1008 results of positive culture from E. coli were investigated. The distinction and separation of sensitive, semi sensitive and resistant from each other implemented based on the diameter size of corona surrounding Escherichia coli colonies in terms of millimeter. In this study, the results of resistance pattern of E. coli among various kinds of antibiotics showed that the highest sensitivity was related to Meropenem (91.6%) and Imipenem (91.2%) and the highest resistance was related to Sulfamethoxazole (54.4%) and Cefotaxime (29.3%). According to the results of this study, it is necessary to periodically once in an every multiple year in each area, the antibiotic resistance pattern has to be explored for proper usage in the treatment of patients and it can be a suitable criterion for prescribing antibiotics and their sensitivity and resistance situation.
