- to compare colonization of group b streptococcus (gbs) in diabetic and non-diabetic pregnant women. in this prospective study 50 pregnant women with diabetes mellitus (both pregestational and gestational) and 43 pregnant women without diabetes between 33 and 37 weeks' gestation were evaluated. three samples for group b streptococcal culture detection were obtained from each subject in the fol...

Sr. Director: Recently it has published in Nefrologia a case of haemolytic uremic syndrome associated to pneumococcal infection (SP-HUS) in a 2-year-6-month old boy with pneumonia, that required veno-venous hemodiafiltration / hemofiltration during ten days. SP-HUS is an uncommon disease whose incidence, following invasive pneumococcal infection, is estimated at 0.4-0.6 %. Its mortality rate is...

Introduction: Hemolytic streptococci are one of the most frequent human pathogens capable of producing a variety of diseases ranging from pharyngitis, impetigo, to more severe and life threatening diseases like Toxic Shock Syndrome, neonatal sepsis, pneumonia and meningitis. Though they are still susceptible to commonly used antibiotics, resistance is increasingly reported. Materials and Method...

A new selective medium (CNA-P) that reduces or eliminates the inhibitory activity of bacteriocin-producing Streptococcus salivarius against beta-hemolytic streptococci has been developed and compared with sheep blood agar (SBA) for the sensitive detection of small numbers of beta-hemolytic streptococci in clinical specimens. CNA-P has as its basis a commercial medium (Difco Columbia CNA agar) s...

A bacterium was isolated from the blood culture of a patient with infective endocarditis. The cells were facultative anaerobic, nonsporulating, gram-positive cocci arranged in chains. The bacterium grows on sheep blood agar as alpha-hemolytic, gray colonies of 0.5 to 1 mm in diameter after 24 h of incubation at 37 degrees C in ambient air. Growth also occurs in 10 or 40% bile and on bile esculi...

The American boy of six and one-half years, the son of missionaries to the Belgian Congo, whose case was reported in a preliminary way by Dr. E. van Oye and Dr. M. Ballion (1), was brought back home to the United States and was referred to us because of our interest in surgical infections. Although we were told acid-fast organisms had been found in this lesion, it had some of the characteristic...

this study aimed to assess the anticariogenic and hemolytic activity of crude plant seed protein extracts against tooth decaying bacteria.the proteins from seeds of 12 different plants were extracted and used for antimicrobial assay against six different organisms. the extraction was carried out in 10mm of sodium phosphate buffer (ph 7.0). protein concentrations were determined as described by ...
