Abstract

Antibiotic-resistant bacteria have become a major public health issue. It happens naturally, though human and animal overuse of antibiotics has accelerated the process. A drinking water treatment system is specifically intended to remove germs and diseases from water. The presence of antibiotic-resistant bacteria in the Nile River's surface water as well as in Dakahlia's drinking water. The results recorded a total of 39 isolates belong to 14 isolates coliforms, 13 isolates fecal coliforms, and 12 isolates fecal enterococci. Ten antibiotics were used for the determination of antibiotic resistance profiles of these isolates. The most resistant antibiotics of the Nile waters-isolates were amoxicillin (95%), and ampicillin (90%), and in tap water were clarithromycin (85%), and amoxicillin (83%). The MARI values for the Nile raw water were three times greater than the permitted limit (
