ABSTRACT
Objective - To evaluate the frequency of the bacterial agents responsible for urinary tract infections and the antimicrobial sensitivity profile of the uropathogens involved in these infectious processes. Methods - A survey was conducted of the data with reference to uroculture exams of patients attended at the Military Police Hospital of the State of Goiás, Brazil, in the period from January, 1998 to December, 2008, in which it was verified that of the 10,162 urine samples, 1,506 (14.82%) were positives, while 8,656 (85.18%) presented no growth of microorganisms. Results - According to the results, it was verified that the female sex was the most affected (79.4%). The most frequent Gram negative bacteria were Escherichia coli (63.08%) and Enterobacter sp. (6.31%) and the Gram-positive bacteria were Staphylococcus saprophyticus (4.52%) and Staphylococcus aureus (3.19%). Conclusion - With regard to bacterial susceptibility to antimicrobial agents, it was noted that Escherichia coli and Enterobacter sp. presented a higher sensitivity index in decreasing order to Ciprofloxacin, Norfloxacin and Ceftriaxon.

Métodos - Foi realizado levantamento dos dados referentes aos exames de uroculturas de pacientes atendidos no Hospital do Policial Militar do Estado de Goiás, Brasil, no período de janeiro/1998 a dezembro/2008, onde verificou-se que das 10.162 amostras de urina, 1.506 (14,82%) foram positivas, enquanto 8.656 (85,18%) não apresentaram crescimento de microrganismos. Resultados - De acordo com os resultados verificou-se que o sexo feminino foi o mais acometido (79,4%). As bactérias Gram-negativas mais frequentes foram Escherichia coli (63,08%) e Enterobacter sp. (6,31%) e as Gram-positivas foram Sthaphylococcus saprophyticus (4,52%) e Staphylococcus aureus (3,19%). Conclusão - Com relação à susceptibilidade bacteriana aos antimicrobianos notou-se que a Escherichia coli e Enterobacter sp. apresentaram maior índice de sensibilidade de forma decrescente à Ciprofloxacina, Norfloxacina e Ceftriaxona.
ABSTRACT
Background: Chlamydia trachomatis and Neisseria gonorrhoeae are common sexually transmitted diseases among young women and little has been doing to study them in Chilean adolescents. Aim: Determine the rates of C trachomatis and N gonorrhoeae in Chilean young women. Material and methods: Urine samples were obtained from 203 sexually active females under 25 year-old, who attended hospitals from either high or low-income areas in Chile's capital, Santiago. C trachomatis and Ngonorrhoeae were detected by nucleic acid amplification testing. Results: Seven percent of samples were positive for C trachomatis. AU samples were negative for N gonorrhoeae. Among pregnant women, 19 percent of samples were positive for C trachomatis, while non-pregnant women were positive on 5.5 percent (p =0.04). Systematic use of barrier contraception was referring by 12 percent of women. AU of the latter was free of C trachomatis. No association was observing between age, number of sexual partners, age of first sexual intercourse, and presence of uro-gynecological symptoms, socioeconomic status and the rate of C trachomatis. Conclusions: Seven percent of this group of Chilean young women was infected with C trachomatis. The figure rises to 19 percent if pregnant. Surveillance and screening programs should been implemented to prevent sequels on this vulnerable population.
