Bacterial Phenotype Variants in Group B Streptococcal Toxic Shock Syndrome1
We conducted genetic and functional analyses of isolates from a patient with group B streptococcal (GBS) necrotizing fasciitis and toxic shock syndrome. Tissue cultures simultaneously showed colonies with high hemolysis (HH) and low hemolysis (LH). Conversely, the HH and LH variants exhibited low capsule (LC) and high capsule (HC) expression, respectively. Molecular analysis demonstrated that t...
متن کاملPostabortal Group A Streptococcal Sepsis and Toxic Shock Syndrome
A 20-year-old woman developed lower abdominal pain and fever within 48 h of undergoing an elective termination of a 10 week pregnancy by suction dilation and curettage. Progressive clinical deterioration prompted an exploratory laparotomy which revealed necrotic ovaries bilaterally (A). Areas of the myometrium were also ne-crotic and hemorrhagic (B). An abdominal hysterectomy and bilateral salp...
متن کاملStreptococcal Toxic Shock Syndrome Manifesting
Group A Streptococcus (GAS) is known to cause infections such as pharyngitis, pneumonia, impetigo, erysipelas, necrotizing fasciitis, and septicemia, and can be complicated by rheumatic fever, glomerulonephritis, and erythema nodosum [1]. In 1987, Cone et al described two patients with severe GAS infections who had clinical features similar to staphylococcal toxic shock syndrome (TSS). This syn...
متن کاملGroup B Streptococcal Toxic Shock Syndrome and covR/S Mutations Revisited
Gene mutations in the virulence regulator CovR/S of group A Streptococcus play a substantial role in the pathogenesis of streptococcal toxic shock syndrome. We screened 25 group B Streptococcus (GBS) isolates obtained from patients with streptococcal toxic shock syndrome and found only 1 GBS clone harboring this kind of mutation.
متن کاملGroup B Streptococcal Sepsis in a Newborn: a Case Report
Newborns’ bacterial infections due to group B Streptococcus (GBS) happen in two forms including early-onset disease or late-onset disease. In this paper, we report a case of early-onset GBS infection in a male infant. A 22-year-old primigravid woman delivers a term normal looking male infant. Nasal flaring, grunting, and poor feeding presented soon after birth. An empiric treatment wit...
