Identification of tetracycline-resistant R-plasmids in Streptococcus agalactiae (group B).
In this report, 30 tetracycline-resistant clinical isolates of group B Streptococcus were examined to assess the extent to which tetracycline resistance is plasmid mediated. Of these, 27 showed no physical or genetic evidence of plasmid-mediated resistance; however, one conjugative and two small (3.5 X 10(6)-dalton) multicopy non-self-transmissible tetracycline resistance plasmids were identifi...
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 کاملIn vitro Activity of Solithromycin (CEM-101) Against Macrolide-resistant Streptococcus agalactiae (Group B Streptococcus)
Introduction: Streptococcus agalactiae (Group B Streptococcus or GBS), now recognized as a qualified infectious disease pathogen (QIDP) by the FDA, remains the leading cause of morbidity and mortality among infants in the United States. Although the incidence of GBS in pregnancy has decreased, penicillin and ampicillin minimal inhibitory concentrations (MICs) for GBS have risen, requiring highe...
متن کاملUse of a serotype-specific DNA microarray for identification of group B Streptococcus (Streptococcus agalactiae).
Group B Streptococcus (GBS; Streptococcus agalactiae) is an important cause of sepsis and meningitis. Nine GBS serotypes, based on capsular polysaccharide (CPS) antigens, have been described. Their distribution varies worldwide and needs to be monitored to understand the epidemiology of GBS disease and inform the development of vaccines. In this study, we sequenced cpsH of GBS serotype II (cpsH...
متن کاملAntibiotic susceptibility profile of group B streptococcus (Streptococcus agalactiae) at the Maternity Hospital, Kuwait.
OBJECTIVES This study was designed to determine the antibiotic susceptibility profile of clinical isolates of group B streptococcus(GBS, Streptococcus agalactiae) and to use the information for formulating appropriate intrapartum antibiotic policy for GBS carriage in pregnancy. MATERIALS AND METHODS A total of 1,166 clinical isolates (single isolates) of GBS obtained from vaginal/rectal sampl...
