Epidemiological, biochemical and antimicrobial susceptibility characteristics of Streptococcus pseudoporcinus isolated in Quebec, Canada, from 1997 to 2006

Abstract

From 1997 to 2006, in the province of Quebec, Canada, 15 isolates of Streptococcus pseudoporcinus from 1 urine and 14 vaginorectal cultures were recovered from the genitourinary tract of pregnant women. All these women originated from the Caribbean or sub-Saharan Africa (P=0.00045 compared with a suitable control group). The S. pseudoporcinus isolates were compared to eight isolates of Streptococcus porcinus identified in Quebec from 1995 to 2006, all from animals, of which five were swine. 16S rRNA gene sequencing was required to differentiate between S. pseudoporcinus and S. porcinus animal isolates.
