There are solitary examples of other alditol phosphates as components of this class of polymers. Arabinitol 1-phosphate is part of the S. pneumoniae type 17F capsular polysaccharide. o-Glucitol 6-phosphate is a component of the group-specific polysaccharide from group B Streptococcus, which has a most unusual, ramified structure. In a polysaccharide from Nocardia...

The antibiotic of choice for group B streptococcal disease is penicillin G, although ampicillin is an alternative.43 No resistance to either agent has been reported, and their narrow spectrum of activity makes them ideal choices.43 Resistance has developed with the use of alternative choices for penicillin-allergic patients. A treatment algorithm for group B Streptococcus is shown in Fig. 44—3, and dosing recommendations are shown in Table 44-5.

Group B Streptococcus bacteriuria should be treated to reduce the rate of preterm delivery. These women should also receive antibiotics at delivery to prevent infection in the newborn. 

The currently recommended regimen for group B Streptococcus disease is penicillin G, 5 million units IV, followed by 2.5 million units IV every 4 hours until delivery. Alternatives include ampicillin, 2 g IV, followed by 1 g IV every 4 hours cefazolin 2 g IV, followed by 1 g every 8 hours clindamycin, 900 mg IV every 8 hours or erythromycin, 500 mg IV every 6 hours. In women who are penicillin-allergic, and in whom sensitivity testing shows the organism to be resistant to clindamycin and erythromycin, vancomycin 1 g IV every 12 hours until delivery can be used.

Younger than 7 days of age 50,000 units/kg/day in divided doses every 12 hours (group B streptococcus, 100,000 units/kg/day meningitis, 100,000 to 150,000 units/kg/day). 

By applying the NOESY step first, this experiment allows us to jump from one spin system to another or to overcome a bottleneck in TOCSY transfer caused by an occurrence of a small coupling constant in the chain of J-connectivities. Both these features are illustrated in ID NOESY-TOCSY spectra of the type VI group B Streptococcus capsular polysaccharide (1). 

When culture results of CSE and/or blood are available therapy should always be streamlined. If the meningococcus, pneumococcus, group B streptococcus or Listeria are penicillin sensitive, this small spectrum agent (benzylpenicillin 6x3 million units/day i.v.) would be the therapy of choice.
