Streptococcus agalactiae (Group B Streptococci) carriage in late pregnancy in Kuwait.
OBJECTIVES This study investigated the vaginal colonization rate of Streptococcus agalactiae (group B streptococci, GBS) in an antenatal population in a maternity hospital. SUBJECTS AND METHODS Anal, vaginal and combined anal and vaginal specimens were obtained from 110 pregnant women (mean age 30.7 +/- 5.5 years) at 35-37 weeks of gestation, using a commercially prepared culturette, and tran...
متن کاملSurvey of strain distribution and antibiotic resistance pattern of group B streptococci (Streptococcus agalactiae) isolated from clinical specimens
AIM The aims of the present study were to determine the antibiotic susceptibility profils with particular emphasis on susceptible or resistant strains to macrolides and lincosamids antibiotics and to determine possible antibiotic resistance mechanisms occurring in group B streptococci (GBS) strains using PCR assay and disk diffusion method. METHODS A total of 62 clinical GBS strains were inve...
متن کاملInternational external quality assurance for laboratory identification and typing of Streptococcus agalactiae (Group B streptococci).
We report the results from the first international multicenter external quality assessment (EQA) studies for molecular and serological typing of group B streptococcus (GBS) strains as part of DEVANI (Design of a Vaccine against Neonatal Infections), a pan-European program. A questionnaire-based surveillance was undertaken among eight laboratories participating in DEVANI and six laboratories not...
متن کاملToxicity of group B Streptococcus agalactiae in adult rats.
Several strains of group B Streptococcus agalactiae were found to be lethal for young adult rats. When bacteria were heat killed and then injected intraperitoneally into rats, rapid death (14 to 18 h) of the rats occurred, characterized by labored breathing, hemolyzed serum, hemoglobinuria, and subungual hemorrhages. Sections of tissues from these rats failed to reveal the cause of death. Rats ...
متن کاملFluoroquinolone-resistant Streptococcus agalactiae: epidemiology and mechanism of resistance.
Quinolone-resistant Streptococcus agalactiae bacteria were recovered from single-patient isolates and found to contain mutations in the gyrase and topoisomerase IV genes. Pulsed-field gel electrophoresis demonstrated that four isolates from the same long-term care facility were closely related; in seven cases, quinolone-resistant Haemophilus influenzae and S. agalactiae bacteria were isolated f...
