PURPOSE To examine whether herpes zoster antigen (also called varicella-zoster virus antigen) was detectable in temporal artery biopsies taken from individuals with giant cell arteritis (GCA). DESIGN Retrospective comparative case series. METHODS Sections of formalin-fixed paraffin-embedded temporal arteries were examined first by hematoxylin-eosin (H&E) staining to establish the diagnosis ...

Of 3,200 cultures of Escherichia coli isolated from streams in Pennsylvania over a 7-year period, 82.46% or 2,639 were O serogrouped. The largest number of cultures (33.4%) belonged to O groups 1 to 26, and the second highest number (16.8%) belonged to O groups 60 to 88. The individual E. coli O groups most frequently isolated were ADO3, 18ac, 2a, 3, 7, 73, 139, and OX13. Practically every know...

The O-antigen moiety of the LPS is one of the most variable cell surface components of the Gram-negative bacterial outer membrane. Variation is due to the presence of different sugars and sugar linkages. Here, it is reported that a group of Escherichia coli O serogroups (O17, O44, O73, O77 and O106), and the Salmonella enterica serogroup O : 6,14 (H), share a common four-sugar backbone O-subuni...

Background: During pregnancy, the maternal immune system is in close contact with cells and tissue from the semiallogenic fetus .The Human Leucocyte Antigen (HLA) class Ib molecules, HLA-E, -F and -G, are expressed at the materno-fetal interface. Because of the apparent immunoregulatory functions of these proteins, they may be involved in successful acceptance of the semi-allogenic fetus during...

In progression of tumours, resulting from, i.e., release of cells from the parental tumour and development of metastases, expression of cell adhesion molecules (CAM) plays a significant role. CAM, including E-cadherin and the linked to it β-catenin, determine the extent of adhesion between normal and neoplastically altered cells. Moreover, the unbound form of β-catenin in a cell nucleus may aff...

BACKGROUND Giardiasis is a common, potentially zoonotic disease, and dogs often harbor and shed cysts without showing clinical signs. Treatment with the probiotic Enterococcus faecium SF68 has been shown to stimulate mucosal and systemic immunity in a variety of animal models and in young dogs, and to reduce giardial cyst and antigen shedding in rodents. HYPOTHESIS Adult dogs with chronic nat...

A collection of 33 Escherichia coli serogroup O15 strains was studied with regard to O:H serotypes and virulence markers and for detection of the O-antigen-specific genes wzx and wzy. The strains were from nine different countries, originated from healthy or diseased humans and animals and from food, and were isolated between 1941 and 2003. On the basis of virulence markers and clinical data th...

Shigella dysenteriae type 1 is the most virulent serotype of Shigella. Enterotoxigenic Escherichia coli O148 is pathogenic and can cause diarrhoea. The following structure was established for the tetrasaccharide repeating unit of the E. coli O148 O antigen: -->3)-alpha-L-Rhap-(1-->3)-alpha-L-Rhap-(1-->2)-alpha-D-Glcp-(1-->3)-alpha-D-GlcpNAc-(1-->. This differs from the structure reported earlie...

Suzuki, T. (Children's Hospital, Buffalo, N.Y.), E. A. Gorzynski, and E. Neter. Separation by ethanol of common and somatic antigens of Enterobacteriaceae. J. Bacteriol. 88:1240-1243. 1964.-Ethanol in a concentration of 85% permits separation from crude culture supernatant fluids of the common enterobacterial antigen and the O antigen, the former being ethanol-soluble, the latter being ethanol-...

An increasing number of infertile, hepatitis B virus-infected individuals have opted for assisted reproductive technology. However, the impact of the hepatitis B virus carrier serostatus on neonatal outcomes has not been evaluated. Data from 504 patients who delivered singletons were analyzed. In females, hepatitis B surface antigen, hepatitis B e antigen, and antibody to hepatitis core antigen...
