A total of 174 blood isolates of Escherichia coli, collected during a 5-year period at the University Hospital Utrecht, were serotyped with rabbit sera against 171 O antigens and 73 capsule (K) antigens. The four most prevalent O-antigen serotypes were O6 (n = 22), O18 (n = 19), O1 (n = 19), and O2 (n = 15). Thirty-one strains were not typeable with any of the O-antigen-typing sera. Of the 148 ...

Neonatal bacterial meningitis continues to be an important cause of mortality and morbidity worldwide. Escherichia coli possessing the K1 capsular polysaccharide is the most common Gram-negative pathogen causing neonatal meningitis. Here we present the complete genome sequence of neonatal meningitis-associated E. coli strain CE10, a unique K1 strain with a functional type III secretion system. ...

We study the projective space S of rational parameter representations of degree d or less in real projective space P. The parameter representations of degree less than d form a special algebraic variety K1. We investigate the subspaces on K1 and their relation to rational curves in P, give a geometric characterization of the automorphism group of K1 and outline applications of the theory to pro...

For developing race-specific anthropometry-based total body water (TBW) equations, we measured TBW using bioelectrical impedance analysis (TBW(BIA)) in 2,943 healthy Korean adults. Among them, 2,223 were used as a reference group. Two equations (TBW(K1) and TBW(K2)) were developed based on age, sex, height, and body weight. The adjusted R2 was 0.908 for TBW(K1) and 0.910 for TBW(K2). The remain...

BACKGROUND In humans trophoblast invasion and vascular remodeling are critical to determine the fate of pregnancy. Since guinea-pigs share with women an extensive migration of the trophoblasts through the decidua and uterine arteries, and a haemomonochorial placenta, this species was used to evaluate the spatio-temporal expression of three enzymes that have been associated to trophoblast invasi...
