Role of pathogens distribution and urine pH changes in urinary tract infection for clinical prevention and treatment / 第三军医大学学报

ABSTRACT

Objective To explore the distribution of pathogens and the characteristics of the urine pH values in urinary tract infection (UTI),and provide a new idea for clinical prevention and treatment of UTI.Methods The data of 606 strains of pathogens and the infected urine pH values from urinary samples of patients with UTI from January 2007 to November 2009 in our hospital were obtained.The distribution of pathogens was detected,and these pathogens were divided into 3 groups according to the genus.Urine pH value of different pathogens was analyzed.Results Among 606 strains from UTI,the group of escherichia ranked the first with 186 strains (30.7%),and the infected urine pH by this bacteria ranged from 6.21 to 6.33.A total of 152 strains of candida were detected (25.1%),and the infected urine pH value was from 5.81 to 5.95.There were 86 strains of enterococcus detected (14.2%),and the infected urine pH was from 6.10 to 6.28.By contrasting the infected urine pH of these 3 groups,the infected urine pH by candida was acidic significantly (P
