Microorganisms prevalent in urinary tract infections and antimicrobial sensitivity profile: analysis of patients attended at the Military Police Hospital of the State of Goiás, Brazil, in the period from 1998 to 2008 / Microrganismos prevalentes em infecções do trato urinário e perfil de sensibilidade antimicrobiana: análise dos pacientes atendidos no Hospital do Policial Militar do Estado de Goiás, Brasil, no período de 1998 a 2008

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.

RESUMO

Objetivo - Avaliar a frequência dos agentes bacterianos responsáveis por infecções do trato urinário e o perfil de sensibilidade antimicrobiana dos uropatógenos envolvidos nestes processos infecciosos. 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.
