Abstract: 
Background and objectives: Diarrheal diseases remain as an important public health concern.
Diarrhea genic Escherichia coli (DEC) is among the most important bacterial enteric pathogens, particularly in developing countries. DEC is classified into 6 categories: enteropathogenic E. coli (EPEC), enterohemorrhagic E. coli (EHEC), enterotoxigenic E. coli (ETEC), enteroinvasive E. coli (EIEC), enteroaggregative E. coli (EAEC), and diffusely adhering E. coli (DAEC). EAEC is a common bacterial cause of diarrhea among travelers' to developing countries, is the second most common cause of (ETEC is the most common cause) and a cause of persistent diarrhea and malnutrition in children and HIV-infected persons living in developing and developed countries.
EAEC is increasingly recognized as an emerging enteric pathogen. Because of bad effects of diarrhea especially interference with growth in children, antibacterial treatment is recommended in some cases. But resistance and sensitivity of any strain in any area must be determined.
Materials and methods: Therefore in the present study 204 isolates of EAEC identified by multiplex PCR designed for this purpose (AA, aap and aggR) from diarrheal children were checked for the antibiotic resistance pattern. The sensitivity of the isolates was checked for 11 different antibiotics, with disk diffusion assay.
Results: The results obtained here, revealed that except for ciprofaxacin (CIP) and Nalidexicacid (NA) for the rest of antibiotics the isolates exhibited resistance. Among typical and atypical EAEC isolates the resistance pattern was not so different and resistant to more than one antibiotic was found to be common phenomenon among these isolates.
Conclusion: The results obtained here indicated that the antibiotic usage is not in a regulated and defined manner and this makes a management of infectious diseases a difficult task.
