tyvelose

03/01/2002 - "The data show that, with the experimental design employed, there was no evidence for a functional role of tyvelose in either host- or parasite-protection during the intestinal phase of infection."
03/01/2002 - "Equally, priming with tyvelose-BSA before boosting with larval antigen had no effect on the expression of immunity against a challenge infection. "
03/01/2002 - "The possibility that the tyvelose component itself may have a host- or parasite-protective role in the intestine was tested by following the outcome of challenge infections in mice primed and boosted with tyvelose-BSA, or in mice primed with tyvelose-BSA before boosting with larval antigen. "
09/01/1999 - "L1 larvae in the muscle at the end stage of infection stimulate a second antibody response against tyvelose-bearing glycoproteins. "
06/01/2004 - "Muscle infection also elicited an antibody response, characterized initially by mixed isotypes directed at somatic larval antigens and changing to an immunoglobulin G1-dominated response directed at tyvelose-bearing excreted or secreted antigens. "

09/05/2005 - "Using ELISA and Western blot analysis (Trichinella-specific IgG antibodies against excreted/secreted antigen and synthetic tyvelose antigen, respectively) four of these persons were found to be sero-positive for Trichinella antibodies, with three of these having clinical symptoms compatible with trichinellosis. "
08/01/2004 - "Comparison of synthetic tyvelose antigen with excretory-secretory antigen for the detection of trichinellosis in swine using enzyme-linked immunosorbent assay."
06/01/2001 - "In trichinellosis patient sera, specific IgG were present in 100% of cases, irrespective of the antigen used, but whereas specific IgE were detected in 78% using E/S antigens, a 100% positivity rate was obtained, using the beta-tyvelose-BSA conjugate."
09/01/2004 - "To identify Trichinella antigens suitable for high-specificity and high-sensitivity serodiagnosis of human trichinellosis, we evaluated assays using four antigens: (i) crude first-stage larval extract (CLE), (ii) O-deglycosylated CLE, (iii) tyvelose-bearing antigens (Trichinella spiralis larva group 1 [TSL-1] antigens) purified by US4 affinity chromatography and coupled directly to enzyme-linked immunosorbent assay (ELISA) plates (pTSL-1 antigens), and (iv) TSL-1 antigens immobilized on ELISA plates with the monoclonal antibody (MAb) US4 (cTSL-1 antigens). "
08/01/2004 - "Two enzyme-linked immunosorbent assay (ELISA) systems, one using natural excretory-secretory (ES) antigens and the other a synthetic glycan antigen (3,6-dideoxy-D-arabinohexose [tyvelose, TY]), were evaluated for the serological diagnosis of trichinellosis in swine. "

07/01/1961 - "Dideoxysugars of Pasteurella pseudotuberculosis-specific polysaccharides, and the occurrence of ascarylose."
03/01/1974 - "Lipopolysaccharide prepared from cells of Yersinia (Pasteurella) pseudotuberculosis of serogroups I, II, III, IV, and V is known to contain the 3,6-dideoxyhexose (DDH) paratose, abequose, paratose, tyvelose, and ascarylose in its respective O-specific side chains. "

01/01/2005 - "We describe the characterization of Salmonella enterica serovar Typhi, isolated from the blood of patients with perforation and non-perforation typhoid fever, by a combination of conventional microbiological tests, 16S rRNA gene sequencing, and flagellin gene and CDP-tyvelose epimerase (rfbE) gene sequencing.
