Streptococcus agalactiae as a urinary tract pathogen in males and non-pregnant females

Abstract

The role of Streptococcus agalactiae (group B streptococci, GBS) was investigated for a period of one year in different clinical forms of urinary tract infection in males and non-pregnant females over 14 years of age. The pathogen has been isolated in quantities of greater than or equal to 10(5) cfu/ml in midstream voided urine from 32 patients with clinical signs of urinary tract infection and pathologic urinary sediment. In every group of B isolates the antibiotic sensitivity to antimicrobial agents was determined by the single disk method of Kirby-Bauer. GBS with the same characteristics were established in urethral specimens of 4 males as well as in the vagina and faeces of 11 females. As a rule, peroral treatment with ampicillin proceeded successfully. In addition, women with streptococcal vaginitis were treated topically with 2% solution of chlorhexidine. Our results have demonstrated that GBS might cause urinary tract infection, but the evaluation of GBS isolated in urine specimens is complex.

“…60 Girgitzova et al took culture samples from urine in parallel with feces and ureteral or vaginal swabs. 59 They found that GBS isolates from feces had similar antimicrobial sensitivity profiles to that of the urine and genital isolates, reinforcing that the GI tract is often the reservoir for GBS within the human host. 59 A multicenter study by Vigliarolo et al evaluated incidence of UTIs in adult patients from Argentina.…”

“…58 Data regarding rates of GBS urinary infection in non-pregnant adults is sparse, though some studies from as early as the 1970′s identified the relationship between DM and GBS urinary infection. [59][60][61] Persson et al examined GBS positive urine cultures from men and non-pregnant women in Sweden from 1982 to 1984. 60 After reviewing over 67,000 urine specimens, the authors identified 240 GBS cultures from 163 patients, 19 males and 144 females.…”
