Studies at two Brown Medical School-affiliated hospitals were undertaken to evaluate a new selective broth medium (GBS broth) and to compare it to the LIM broth currently used to culture for group B streptococci. Beta-hemolytic group B streptococci produce a carotenoid pigment that turns GBS broth an orange color. From a total of 580 pregnant women, duplicate vaginal-rectal swabs were collected...

Background and Objective: Early diagnosis of Streptococcus agalactiae remains difficult, since symptoms are very nonspecific. Its frequency has not been completely investigated in urinary tract pathogen of pregnant ant and non pregnant women in Iran. The aim of this study was determining the frequency of Group B Streptococci in female patients. Materials and Methods: A Total of 11800 urine spec...

OBJECTIVE To evaluate the costs and benefits of a group B streptococci screening strategy using a new, rapid polymerase chain reaction test in a hypothetical cohort of expectant mothers in the United States. METHODS DESIGN Cost-benefit analysis using the human capital method. We developed a decision model to analyze the costs and benefits of a hypothetical group B streptococci screening st...

The recognition of Lancefield's Group A as the most,commonly pathogenic members of the haemolytic streptococci has prompted several attempts at devising a rapid cultural diagnostic method such as the addition of maltose or glucose to blood agar, which alters the haemolytic activity of Group A strains (Kodama, 1937; Simmons and *Wilson, 1941). This paper describes the use of an antibiotic that i...
