Rabbits and guinea pigs were immunized with purified bovine rotavirus. Immunoglobulin G fractions of the resulting antisera were used in a standard four-layer solid-phase enzyme immunoassay (EIA) for rotavirus antigen in human faecal specimens. Sampl

196 episodes of urinary tract infection in children were analysed. 74 were classified as pyelonephritic (PN), 61 as cystitis (C), and 61 as asymptomatic bacteriuria (ABU) on the basis of three clinical signs (elevated temperature, erythrocyte sedimen

Sixty-three Escherichia coli strains isolated from neonatal sepsis or meningitis were studied and compared with previous data on fecal or urinary pyelonephritis-associated isolates from children. Characteristics significantly associated with neonatal

Binding characteristics of the purified Escherichia coli O75X adhesin in frozen sections of human kidney were determined, using antibodies raised against the purified antigen and rhodamine-conjugated second antibodies. To identify the adhesin-binding

SUMMARY: Deletion mutants of recombinant plasmids encoding the KS71B fimbrial antigens of the uropathogenic Escherichia coli strain KS71 (O4:K12) were constructed. The effects of these mutations were tested by transforming the mutated plasmids into n

A method for studying adhesion of fluorochrome-stained Escherichia coli to cryostat sections of human kidney is described. Of the 3 model strains used, the P-fimbriated strain KS71 adhered more effectively than the type-1-fimbriated or nonfimbriated

The pyelonephritogenic Escherichia coli strain 1 H 11165 specifically agglutinates human erythrocytes carrying the M blood group antigen. The polymorphic forms of this antigen, M and N, are located in the NH2-terminal region of the major human red-ce

The rate of fimbrial phase variation in Escherichia coli strain 3040 was determined. The strain has type-1 and S fimbriae. The bacterial culture was fractionated into homogeneous subpopulations expressing either one of the fimbrial types only; the su

The organization of genes encoding the blood group M-specific hemagglutinin (M-agglutinin) of Escherichia coli strain IH11165 was studied with a cloned 6.5-kb DNA segment. This DNA segment contains at least five genes which code for the polypeptides

Fluorochrome-labeled antibodies specific for either S or type-1 fimbriae of Escherichia coli were used to show that in broth culture the two fimbrial types of strain 3040 mostly occurred on different cells. 12% of the cells were nonfimbriated. A frac
