Group B streptococcal disease is a common cause of bacterial sepsis in newborns and is often fatal. To protect these babies, a vaccination program must target pregnant women for immunization so that the resulting antibodies can be passively delivered from the mother to the fetus. Scientists met in Siena, Italy, to discuss potential approaches to maternal immunization for the prevention of perin...

Streptococcal grouping sera, diluted and absorbed to remove cross-reactions, were bound to staphylococci and used to group trypsinised beta-haemolytic streptococci by coagglutination. The results compared well with those obtained using the Phadebact streptococcal grouping kit. The same sera bound to staphylococci without prior dilution and absorption could be used to group enzyme extracts of ha...

All enzyme that destroys DPN has been found in fractionated and highly concentrated streptococcal preparations that also contain streptolysin O. The enzyme-streptococcal DPNase-was shown by electrophoretic separation and by other means to be distinct from streptolysin O. It is non-dialyzable, heat-labile, and has optimal activity in the pH range 7.2 to 7.8. The enzyme has a high degree of speci...

The incidence of group B streptococcal bacteremia in adults has increased in recent years, particularly in patients with severe underlying diseases. However, group B still remains an unusual pathogen in adults in developing countries. We report a case of group B streptococcal bacteremia in a non-pregnant adult, the only case reported in our hospital. The organism was only isolated from the bloo...

The aim of the present work was to evaluate the influence of the lack of urease activity in some Streptococcus thermophilus strains on the primary metabolism during lactic acid fermentation. A comparison of the kinetics of the lactic acid process with the participation of ureautilizing and urease deficient streptococcal strains was performed. It was found that the lack of urease activity in the...

Numerous post-Streptococcal syndromes (PSS) have been described in the literature. The role of antibiotic therapy management PSS is best established with acute rheumatic fever. We present a patient streptococcus-associated medium vessel vasculitis multiple flares despite immunosuppressive that achieved sustained remission long term oral penicillin V 250 mg twice daily.
