Frequency and Antibiotic Resistance Profile of Uropathogens Associated With Community Acquired Urinary Tract Infections

Abstract

U tract infections (UTIs) are among the most common Ubacterial infections diagnosed in community health practice and also of the hospital settings, resulting in high rates of morbidity and high economic costs associated with its treatment. The most frequent uropathogen involved in community-acquired UTI is E. coli (80-90%) due to the fact established being a normal flora of the human intestine and therefore easily colonizing the urinary tract. Other causative organisms are members of Enterobacteriacae family and some Gram positive agents like Staphylococcus saprophyticus and Enterococcus faecalis. Results of antimicrobial susceptibility testing are usually obtained three days after sampling. The early treatment of UTI decreases the rate of morbidity, implying that in most cases antimicrobial therapy is being prescribed empirically. The differences in gender and age must be taken into consideration at the moment of prescription of empirical antimicrobials .In order to administer an appropriate empirical therapy it is crucial to know the main bacteria usually involved in the UTI as well as their antimicrobial resistance pattern. These data allow controlling the increase of antimicrobial resistance and the spread of resistant bacterial strains that represent a public health problem worldwide.
