Background. Urinary tract infection (UTI) is a severe public health problem. However, infected patients are usually treated empirically without preceding culture or antibiotics susceptibility testing, which may increase the antibiotic resistance level. The aim of this study is to determine the prevalence and antibiotic susceptibility patterns of common bacterial uropathogens isolated in Akkar governorate, North Lebanon.

Methods. Spot midstream from urine samples from 9662 patients presenting UTI symptoms who came to Youssef Hospital Center located in Akkar governorate, were collected in sterile plastic cups. Culture, identification and antibiotic susceptibility testing were performed through conventional tools according to the manufacturer’s recommended procedures and the recommendations of the European Committee on Antimicrobial Susceptibility Testing.

Results. Overall, a total of 1009 bacterial uropathogens were isolated. Escherichia coli was predominant and represented 72.5% of all isolates , followed by Klebsiella pneumoniae (8.2%), Enterococcus spp. (5.5%), Pseudomonas aeruginosa (4.5%), Proteus spp. (3%), Enterobacter spp. (2%), Staphylococcus aureus (2%), Streptococcus agalactiae (1.6%), Staphylococcus saprophyticus (0.4%), Acinetobacter baumannii (0.2%) and Providencia rettgeri (0.1%). Moreover, the mean antibiotic resistance rates of isolates was relatively high, but similar to previous investigations reported in our country.

Conclusion. To our knowledge, this is the first investigation reporting epidemiological data regarding the prevalence and antibiotic susceptibility patterns of uropathogens isolated from patients in Akkar governorate. Our data indicated the urgent need of a strategic plan to tackle antibiotic resistance, particularly in deprived regions with poor healthcare structures such as Akkar governorate.
