Abstract :
Background: This study aimed to investigate the bacteria associated with urinary tract infection (UTI) and antibiotic susceptibility
pattern of the isolates during 2013–2015 in Northern Iran. Materials and Methods: Overall 3798 patients with clinical symptoms of
UTI were subjected as samples, and they were cultured and pure isolated bacteria were identified using biochemical tests and subjected
to antibiogram assessment using disc diffusion method. Results: Totally, 568 (14.96%) from 3798 patients had positive UTI. Four
hundred and ninety‑seven (87.5%) from 568 isolated bacteria were resistant to at least one antibiotic. Escherichia coli, Staphylococcus
spp., and Pseudomonas spp. were the most prevalent bacteria. Isolated bacteria indicated the highest antibiotic resistance to
methicillin (76.06%) and ampicillin (89.29%) and also revealed the most sensitivity to imipenem (99.1%) and amikacin (91.57%).
Statistical analysis of the resistance pattern trend during 3 years indicated the insignificant increase (P > 0.05) in antibiotic resistance
of the isolates. Conclusion: The results of this study revealed a great concern for emerging UTI‑related multidrug‑resistant strains
of bacteria causing UTI in Iran.
