Background:

Urinary Tract Infections represent a frequent reason of ambulatory medical consult.

The high and increasing percentages of antibiotic resistance represent a challenge for the physician treating them.

Aim:

To obtain epidemiological information of the sensibility profile from bacteria isolated in urine cultures.

Methods:

Between February and June of 2014, 602 urine culture samples were collected from different laboratories in the cities of San Pedro Sula and El Progreso, Honduras. The variables analyzed were sex, age and bacteria, antibiotics with higher sensibility and with higher resistance in urine culture. The Kirby Bauer method was used to determine the sensitivity and resistance profiles of each urine culture. A total of 47 antibiotics were used in all the laboratories. The variables were correlated to describe the resistance and sensibility profiles of the list of antibiotics.

Results:

The bacteria isolated were E. Coli (70.4%), Enterobacter spp (7.8%), Klebsiella spp (6.3%), Citrobacter spp (6.1%), Proteus spp (2.8%), Staphylococcus s spp (2.7%), Pseudomona aeruginosa (1.8%), Streptococcus spp (1.2%), Hafnia alveii (0.3%), Morganella morgagni (0.2%), Serratia marcenscens (0.2%), Neisseria gonorrhoeae (0.2%). From 602 samples, the general sensitivity reported was: fosfomycin (n=415, 68.9%), amikacin (n=412, 68.4%), nitrofurantoin (n=376, 62.4%), gentamicin (n=364, 60.4%) y ceftriaxone (n=307, 50%). The resistance for all the samples reported was as follows trimetoprim sulfametoxazole (n=302, 50.2%), ciprofloxacin (n=230, 38.2%), levofloxacin (n=221, 36.7%), norfloxacin (n=220, 36.5%) y amoxicilin+clavulanic acid (n=204, 33.9%).

Conclusions:

The results in this research reveal that due to their good sensitivity profile, antibiotics like fosfomycin and nitrufurantoin can be a viable empiric therapy in patients with low urinary, or not complicated tract infection before using wide spectrum antibiotics, always personalizing according to the clinical state of the patient and trying to avoid the development of antibiotic resistance.
