Suscetibilidade antimicrobiana de bactérias isoladas de infecções do trato urinário de pacientes atendidos no Hospital Universitário Bettina Ferro de Souza, Belém - PA / Antibiotic susceptibility antimicrobial of uropathogens isolated from culture of patients with urinary tract infections from the University Hospital Bettina Ferro de Souza, Belém - PA
The major cause of tract infections (UTIs) are bacteria from the intestinal microbiota, and the antibiotictherapy is the mainstay of treatment and prevention of these infections. To establish the profile of bacteria susceptibility in patients with UTI from the UniversityHospital Bettina Ferro de Souza (HUBFS), 919 urine samples were cultured and assessed their susceptibility, to common antibiotics Uropathogens identification was done by traditional biochemical methods and antibiogram was determined by the disk-diffusionmethod. 208(22.6%) urinecultures were positive. There was higher UTI frequency in women (78.9%) and adults (47.6%). Escherichia coli (69.8%), Enterobacter sp (7.2%) and Klebsiella sp (5.8%) were the most frequently isolated Gram-negatives (GN) bacteria. Coagulase negative Staphylococcus (CNS) (4.8%) and S. saprophyticus (2.9%) were the most prevalent among the Gram-positive (GP) bacteria. GN bacteria demonstrated high resistance to ampicilin (69%), amicacin (67.4%); sulfametaxazol-trimetropin (61.5%) and high sensibility only for oxacilin (90%) and ciprofloxacin (80%), with resistance higher than the other tested antibiotics. The results sustain the need to establish a better knowledge of the antibiotic susceptibility profile of the bacteria that cause UTIs to avoid the abusive use of antibiotics.
