the pho-controlled outer membrane porin phoe does not contain specific binding sites for phosphate or polyphosphates.purified phoe-porins were reconstituted into black lipid bilayer membranes, and the selectivity and size of the reconstituted pores were determined. addition of polyphosphates influenced the internal charge situation of the pore resulting in a shift from anion to cation selectivity. however, the pore size as judged from single channel conductances was not influenced by the addition of polyphosphates. a strong inhibition of the pore conductance only occurred when mg2+ was also present in the aque ...19882458341
immunological comparison of constitutive beta-lactamases of gram-negative bacteria by neutralization in zymogram gels: properties of anti-tem-1 and anti-tem-2 sera.the zymogram technique was applied to a beta-lactamase neutralization assay with anti-tem-1 and anti-tem-2 sera. both were shown to contain neutralizing antibodies directed towards various beta-lactamases of gram-negative bacteria. the quantitative neutralization allowed classification into five groups of the 28 beta-lactamases used as standards and 61 from clinical isolates. in the first were enzymes such as tem-1 and tem-2 including tle-1, shv-1, shv-2, penicillinases of klebsiella pneumoniae ...19882460115
effect of macromolecular composition of microorganisms on the thermodynamic description of their growth.most models describing bacterial growth, including the original mosaic non-equilibrium thermodynamic (mnet) description, do not take into account that the macromolecular composition of the cells varies with growth rate. the mnet description of bacterial growth is extended to account for such a variation in macromolecular composition of the cells in order to make the mnet description more generally applicable. klebsiella aerogenes nctc 418 was cultured in a chemostat under glucose- or ammonia-lim ...19882461738
monoclonal antibodies against the capsular k antigen of escherichia coli (o9:k30(a):h12): characterisation and use in analysis of k antigen organisation on the cell surface.monoclonal antibodies were produced against the capsular antigen of escherichia coli serotype k(a)30, using a mouse hybridoma system. the antibodies also recognised the chemically identical capsular polysaccharide produced by klebsiella k20. chemical modification of the k30 polysaccharide indicated that the glucuronic acid residues found in the e. coli k30 capsular antigen were important in the epitope recognised by these antibodies. use of the antibodies as molecular probes revealed the presenc ...19882461792
molecular mimicry between human leukocyte antigen b27 and klebsiella. consequences for spondyloarthropathies.ankylosing spondylitis and reiter's syndrome are the two major spondyloarthropathies highly associated with human leukocyte antigen (hla) b27. although the development of spondylitis is unclear, it has been hypothesized that hla-b27 may predispose to spondyloarthropathies via the phenomenon of molecular mimicry. a computer search for homologies between hla-b27 and microbes revealed a sequence of six consecutive amino acids (glutamine-threonine-aspartic acid-arginine-glutamic acid-aspartic acid) ...19882462350
cross-reacting bacterial determinants in ankylosing spondylitis.the importance of the association between the human histocompatibility antigen human leukocyte antigen-b27 and ankylosing spondylitis is undisputed, but its biologic significance remains unresolved. we have demonstrated specific cross reactivity between a range of enteric bacteria and a specific determinant found only on the surfaces of cells from human leukocyte antigen-b27-positive persons with ankylosing spondylitis. we have proposed that the genetic element coding for this cross-reactive det ...19882462351
post-ercp acute necrotizing pancreatitis.an analysis of acute necrotizing pancreatitis (anp) after endoscopic retrograde cholangiopancreatography (ercp) was carried out. the incidence of anp was 0.5% (5/914) for ercp and 0.5% (2/370) for endoscopic sphincterotomies (est). all the five patients were obese, middle-aged or older women. four had a suspicion of common bile duct stones and the fifth a pancreatic tumour as an indication for ercp. two had most probably a functional sphincteric disorder and the third was without clear pathologi ...19882462849
transfer and expression of the genetic determinants for o and k antigen synthesis in escherichia coli o9:k(a)30 and klebsiella sp. o1:k20, in escherichia coli k12.escherichia coli serotype o9:k(a)30 and klebsiella o1:k20 produce thermostable capsular polysaccharides or k antigens, which are chemically and serologically indistinguishable. plasmid pulb113 (rp4::mini-mu) has been used to mediate chromosomal transfer from e. coli o9:k30 and klebsiella o1:k20 to a multiply marked, unencapsulated, e. coli k12 recipient. analysis of the cell surface antigens of the transconjugants confirmed previous reports that the genetic determinants for the e. coli k(a) anti ...19882463068
human monocytes exposed to biostim (ru 41740) alter lymphocyte mitogenesis: mechanisms of action.the immunomodulatory agent ru 41740 (biostim), which is derived from klebsiella pneumoniae, may augment mitogenic responses of purified human blood lymphocytes. in non-purified preparations, however, responses may be sharply reduced due to the fact that biostim induces monocytes to secrete immunosuppressive factors. this investigation has shown that both these biological activities can be exerted by a single, major glucoprotein fraction of biostim termed f1. the biostim-induced suppression of mi ...19882466802
cross-reactive epitope with klebsiella pneumoniae nitrogenase in articular tissue of hla-b27+ patients with ankylosing spondylitis.synovial tissues from patients with ankylosing spondylitis or reactive arthritis were examined by an immunoperoxidase technique, using antisera to synthetic peptides representing antigens shared between hla-b27.1 and klebsiella pneumoniae nitrogenase. with either antiserum, all hla-b27+ patients with synovial inflammation showed strong immunoperoxidase staining in synovial lining cells, vascular endothelium, and infiltrating inflammatory cells. these findings indicate that antigens showing cross ...19892468338
characteristics and mechanism of action of a heat-stable enterotoxin produced by klebsiella pneumoniae from infants with secretory diarrhea.escherichia coli heat-stable enterotoxins (st) are classified into sta and stb according to their physicochemical and biologic characteristics. sta induces diarrhea, activating the guanylate cyclase-cgmp system. st-like enterotoxins can be produced by bacteria other than e. coli, including klebsiella pneumoniae. a klebsiella st has previously been shown to share some chemical and immunologic characteristics with e. coli st. aiming to define better the nature of klebsiella st, we have screened 23 ...19892470015
synovial expression of hla-b27 related antigens in ankylosing spondylitis. 19882471998
the influence of the o-antigen and the capsular polysaccharide on the establishment of plcmts lysogeny in klebsiella pneumoniae.the o-antigen of the lipopolysaccharide in klebsiella pneumoniae caused a significant reduction in the frequency of establishment of plcmts lysogeny, while the capsular polysaccharide showed no effect on this frequency. the bacterial receptor for plcmts are the lipopolysaccharide-core oligosaccharides, the results suggest that k. pneumoniae strains with an o-antigen in their lipopolysaccharide have a poorly accessible lipopolysaccharide-core (the plcmts bacterial receptor), while k. pneumoniae s ...19892477305
[media for determining the dnaase of klebsiella].a modified medium is suggested for measuring klebsiella dnaase activity; the advantage of this medium is the ability of maximally producing the enzyme. the medium is simple to prepare and may be widely used in practical bacteriology.19892477634
