Bacteremia caused by group G Streptococci, taiwan.

Liao CH, Liu LC, Huang YT, Teng LJ, Hsueh PR - Emerging Infect. Dis. (2008)

Bottom Line: The most common diagnosis was cellulitis (48 cases), followed by primary bacteremia (34 cases).Infection recurred in 9 patients.Mortality rate was low (3.3%); resistance to quinupristin-dalfopristin was high.

ABSTRACT
A retrospective observational study in Taiwan, 1998-2004, identified 92 patients with group G streptococcal bacteremia; 86 had Streptococcus dysgalactiae subspecies equisimilis. The most common diagnosis was cellulitis (48 cases), followed by primary bacteremia (34 cases). Infection recurred in 9 patients. Mortality rate was low (3.3%); resistance to quinupristin-dalfopristin was high.

Pulsed-field gel electrophoresis profiles of all isolates from patients with recurrent group G streptococcal bacteremia. Isolates B1 and B2, Streptococcus canis; other isolates, S. dysgalactiae subsp. equisimilis (see designation of the isolates in Table 2). Lane M, molecular mass marker.

Figure 1: Pulsed-field gel electrophoresis profiles of all isolates from patients with recurrent group G streptococcal bacteremia. Isolates B1 and B2, Streptococcus canis; other isolates, S. dysgalactiae subsp. equisimilis (see designation of the isolates in Table 2). Lane M, molecular mass marker.

Mentions: Among the 9 patients with recurrent bacteremia, the causative agent was S. dysgalactiae subsp. equisimilis for 8 and S. canis for 1. PFGE performed with all 13 available isolates from recurrent cases showed that 10 were identical to that of the initial episode, including 1 in a patient with recurrence of S. canis bacteremia. Sequence typing showed emm type stG485 for 4 patients. The clinical characteristics of the patients and emm typing results are shown in Table 2; PFGE results are shown in the Figure. The underlying diseases of patients with recurrent episodes included genital cancer (4 [44.4%] patients) and history of cellulitis (6 [66.7%]), each of which was significantly correlated with the likelihood of recurrence (p<0.01 for each). Further analysis showed that a previous history of cellulitis was significantly correlated with female sex (p = 0.01), genital cancer (p<0.01), tissue edema (p = 0.02), heart disease (p = 0.04), and post–coronary artery bypass graft (p = 0.03).
