| elisa: enzyme-linked immunosorbent assay. | similar in design to radioimmunoassay, comparable in sensitivity and specificity but easier, safer, and less expensive, this new diagnostic technique uses enzyme-labeled rather than isotope-labeled reagents. the end point is a color change that can be assessed by colorimetry or with the naked eye. various techniques of elisa are described, along with examples of current and potential clinical applications. | 1978 | 215505 |
| purification and properties of a pig heart thiolase with broad chain length specificity and comparison of thiolases from pig heart and escherichia coli. | a thiolase (acetyl coa acyltransferase, ec 2.3-1.16) which acts on substrates of various chain lengths (thiolase i) has been purified from pig heart muscle 366-fold to near homogeneity as judged by gel electrophoresis. its molecular weight was estimated to be 200,000 in the absence and 46,000 in the presence of sodium dodecyl sulfate. kinetic measurements with acetoacetyl coenzyme a, 3-ketohexanoyl-coa, 3-ketooctanoyl-coa, and 3-ketodecanoyl-coa yielded apparent km values of 16, 8.3, 2.4, and 1. ... | 1978 | 344310 |
| microbial iron-chelators and their action on klebsiella infections in the skin of guinea-pigs. | preparations of catechols from ethyl acetate extracts of cultures of klebsiellae in a low-iron medium contained iron-chelators whose potency was measured by the reversal of the bacteristasis of escherichia coli and klebsiellae in unheated horse serum, and of the growth-inhibition of these two organisms by ethylene diamine di-orthohydroxyphenyl acetic acid (edda). as revealed by in situ tests of paper chromatograms, there was a multiplicity of biologically active chelators in the preparations. ca ... | 1978 | 350255 |
| [animal tissue polynucleotide phosphorylase]. | localization, physico-chemical and catalytic properties and possible biological functions of polynucleotide phosphorylase (pnpase) from animal tissues are discussed. in animal tissue cells pnpase has multiple localization; the major amount of the enzyme is localized in the endoplasmic reticulum ribosomes. in the nuclei pnpase, similar to other endo- and exo-rnases participates in the processing of precursor molecules of mature forms of rna, whereas in the cytoplasm it is involved in the destruct ... | 1978 | 350293 |
| hydrogen sulphide-positive strains of escherichia coli from swine. | thirty-two h2s-positive strains of escherichia coli, isolated from the caecal contents or mesenteric lymph nodes or both of 60 apparently healthy pigs, were characterized. eighteen different serotypes and 18 different fermentative types were found. during conjugation with e. coli k12, four strains transferred their hys plasmids linked to raf, and another transferred hys associated with the tc determinant. all hys-raf plasmids belong to incompatibility group fi, whilst tc-hys is an fi- plasmid. | 1978 | 351185 |
| characterization of plasmids that encode for the k88 colonization antigen. | k88 antigen, and important virulence factor in porcine enteropathogenic escherichia coli (eec), can be transferred along with the ability to ferment the trisaccharide raffinose (raf). the plasmids from a number of eec strains that encode these two properties were isolated and characterized. in most strains the k88 and raf genes were found on a single nonconjugative plasmid approximately 50 x 10(6) daltons in size. this plasmid core was conserved with only slight variation among the strains teste ... | 1978 | 352948 |
| effect of heat stable and heat labile escherichia coli enterotoxins and cholera toxin in combination with theophylline on unidirectional sodium and chloride flux in the small intestine of weanling swine. | the effect of heat stable and heat labile escherichia coli enterotoxins or cholera toxin in combination with theophylline on net water, sodium and chloride and unidirectional sodium and chloride fluxes was examined in acute isolated loops of jejunum of weanling swine. the effect of heat stable enterotoxin in combination with theophylline was determined in loops located in the proximal jejunum, while combinations of theophylline and either heat labile enterotoxin or cholera toxin were studied in ... | 1978 | 356942 |
| in vitro adhesion of escherichia coli to porcine small intestinal epithelial cells: pili as adhesive factors. | escherichia coli strains with pili (k99 or 987p) known to facilitate intestinal colonization adhered in vitro to porcine intestinal epithelial cells. these strains adhered equally to both ileal and jejunal epithelial cells. a laboratory e. coli strain that has type 1 pili also adhered to porcine intestinal epithelial cells. when nonpiliated cells derived from 987p+, k99+, or type 1 pilus+ strains were used for in vitro adhesion assays, they failed to adhere. the attachment of piliated bacteria t ... | 1978 | 357285 |
| biological evaluation of a methanol-soluble, heat-stable escherichia coli enterotoxin in infant mice, pigs, rabbits, and calves. | escherichia coli p16 was shown to produce two heat-stable toxins (st) with differing biological activity. the toxins were separated by methanol extraction, and the first, sta, was methanol soluble, partially heat stable, active in neonatal piglets (1 to 3 days old) and infant mice, but inactive in weaned pigs (7 to 9 weeks old); the second, stb, was methanol insoluble, active in weaned pigs and rabbit ligated loops, but inactive in infant mice. it is therefore suggested that use of suckling mice ... | 1978 | 357288 |
| [various aspects of competitive relationship between shigella and escherichia coli]. | one of the aspects of antagonistic relations could be the competence of microorganisms for specific sites of attachement to the epithelium common for shigellae and some e. coli serological types; this was demonstrated on a model of shigella-induced keratoconjunctivitis and in experiments with the hep-2 cells infected with h3-glucose-labeled sh. flexneri 5a, with combined administration of the latter with e. coli 08 and 028. the data obtained emphasized the importance for the development of the i ... | 1978 | 358685 |
| [natural antibodies (isohemagglutinins, heterophilic, antierythrocytic and antibacterial) in children with congenital immunologic deficiency syndromes]. | examination of 30 patients with immunodeficient diseases showed that the system of natural antibodies was considerably changed depending on the form and the extent of deficiency of the immune system: in agammaglobuinemia the antibodies under study were almost completely absent, and in immunological insufficiency with ataxia-teleangiectasis the production of antibacterial antibodies proved to be sharply decreased. the data obtained can be used both for the diagnosis of immunodeficiencies and for ... | 1978 | 358690 |

| escherichia coli strains that cause diarrhoea but do not produce heat-labile or heat-stable enterotoxins and are non-invasive. | three enteropathogenic escherichia coli (e.p.e.c.) strains (o127:k63:h6, o128:k67:h2, and o142:k86:h6) isolated from outbreaks of infantile diarrhoea and one strain from the "normal" colonic flora (e. coli hs) of a healthy adult were fed in doses of 10(6), 10(8), and 10(10) organisms in nahco3 to adult volunteers. the strains, which had been stored for 7--9 years, gave negative results in sensitive tests for heat-labile (l.t.) enterotoxin (y-1 adrenal-cell test), heat-stable (s.t.) enterotoxin ( ... | 1978 | 77415 |
| detecting enteropathogenic strains of escherichia coli of porcine origin. 2. relationship between o and k antigens and the production of enterotoxin in strains isolated from the piglet after weaning. | the production of enterotoxin by biological tests (yl adrenal cells and the suckling mouse) has been examined in 96 strains of escherichia coli, isolated from sick piglets after weaning. there is a good correlation between the presence of the capsular antigen k88 and that of the thermolabile fraction (lt) of the enterotoxin (69.2 per cent of the enteropathogenic strains studied). however, the presence of the thermostable fraction (st) of the enterotoxin of strains which, according to their serol ... | 1978 | 86320 |

| diastereoisomeric glucuronides of oxazepam. isolation and stereoselective enzymic hydrolysis. | oxazepam glucuronide isolated from swine urine by previously published methods was separated into its diastereoisomers by ion-exchange chromatography on a preparative scale. quantitative high-performance liquid chromatography was used to monitor the separation. the two isomers were obtained in analytically pure form and then characterized by elemental analysis, oxazepam content, mass spectrometry, ultraviolet spectroscopy, optical rotation and optical rotatory dispersion-circular dichroism. the ... | 1979 | 35325 |
| an examination of the o and k specificity involved in the antibody-induced loss of the k88 plasmid from porcine enteropathogenic strains of escherichia coli. | the heat-labile k88 antigen, a virulence determinant coded for by a transmissible plasmid, was eliminated from enteropathogenic strains of escherichia coli by passage through media containing antibodies to the heat stable antigens of an abbotstown (o149:k91,k88ac) strain. the plasmid-curing activity of o149 antisera was not o-antigen specific as o149, o45, o8 and o138 strains of e. coli could be 'cured' of their k88 plasmids by this technique. the curing activity was differentiated from the o-an ... | 1979 | 92455 |

| evidence for bactericidal activity of polymorphonuclear leukocytes without phagocytosis. | the relationship between phagocytosis and bactericidal action of polymorphonuclear leukocytes was examined by comparing the functions of cytochalasin d-treated leukocytes with those of the control. measurement of phagocytotic and bacterial dna-degrading activities using escherichia coli prelabeled with [3h]thymidine revealed that phagocytosis and bacterial dna degradation were inhibited by treatment with cytochalasin d to about 50 and 10% of the control, respectively. nevertheless, the bacterici ... | 1979 | 225308 |
| the aetiology of diarrhoea in pigs weaned at two days of age. | when pigs are weaned at two days of age large numbers of excherichia coli appear in the anterior gut and the incidence of diarrhoea rises. the two phenomena do not appear to be directly related because the strains of e coli isolated are not serotypes previously found to be associated with neonatal pig scouring. representative strains of the non-enteropathogenic serotypes did not produce enterotoxin and did not adhere to small intestine brush borders. moreover when antibiotics were fed to elimina ... | 1979 | 228367 |
| the role of thromboxane a2 in endotoxin-induced aggregation of guinea-pig platelets in vitro. | large concentrations of endotoxin lipopolysaccharides (lps) e. coli o127:b8 and e. coli o26:b6 were needed for induction of platelet aggregation in citrated platelet rich plasma (prp) from normal guinea-pigs. when guinea-pigs were actively immunized with lps e. coli o127:b8 their prp became more sensitive to the aggregatory effects of this type of lps. the increase in sensitivity was rather selective since the responses to adp and lps e. coli o26:b6 remained unchanged. in endotoxin-stimulated pr ... | 1979 | 386740 |

| [effect of reduced gastrointestinal motility on the regulation of gastrointestinal flora and the pathogenesis of coli enterotoxinemia in market swine]. | opium tincture and spasmentral were applied to piglets early after weaning and reduced their gastro-intestinal motility, which, however, caused only very minor changes in quantitative germ flora composition in those first days. short-time suppression of gastro-intestinal motility obviously does not result in detrimental consequences to the organism as a whole, since there seem to be several factors which are involved in the control and regulation of the intestinal germ flora. impairment of gastr ... | 1979 | 389190 |
| the ability of cholestyramine resin and other adsorbents to bind escherichia coli enterotoxins. | several adsorbent materials were evaluated for their ability to bind escherichia coli enterotoxins. cholestyramine, a strong anion-exchange resin, bound the heat-labile and the heat-stable types of enterotoxin and reduced significantly their effects in some animal models. however, its efficacy in the treatment of diarrhoeic piglets appeared to be adversely affected by the presence of milk in the alimentary tract. | 1979 | 390155 |
| the binding of lps to the lymphocyte surface. | bacterial lipopolysaccharide (lps) from escherichia coli labelled with tritium has been used to follow the binding of lps to lymphocytes. binding to cells rose to a maximum 2-7 min after addition of [3h]-lps, followed by loss of [3h]-lps from cells, reducing to about 10% of the peak level at 20-30 min. peripheral blood lymphocytes, mesenteric lymph node and thymus cells of the pig and cba, c3h/he and c3h/hej mouse spleen cells all bound [3h]-lps transiently at similar levels. it is concluded tha ... | 1979 | 391698 |

| some biological characteristics of escherichia coli strains isolated from acute diarrhoeal diseases of infants. | the aim of this study was to evaluate the methods of biological characterization of escherichia coli strains, in order to use them as screening tests in clinical microbiological laboratories. in two thirds of the 45 e. coli, isolated from acute intestinal infection of infants, different factors of virulence were found. the strains showed prevalently an enterotoxigenic character (66,6%), which was in correlation with the increased permeability (62,2%). adhesive properties were present in 20% of e ... | 1979 | 396738 |
| course of antibiotic sensitivities in escherichia coli and staphylococcus aureus from animals. | in order to establish the evolution of resistance against the common antibiotics from the beginning of their use up to the present time, the sensitivity of escherichia coli isolated from the cecum of wild boars was determined. the mic's of e. coli from these animals in a zoological garden was examined for comparison. the samples from the wild boars were collected in five forests in the belgian ardennes. the mic's obtained (table 1) are comparable to the mean values given in the early literature ... | 1979 | 397700 |
| enterotoxins of enteric bacteria--a review. | a review of the enterotoxins of enteric bacteria was compiled, taking into account recent developments of the field as well as results of the author's own research work. after characterization of enterotoxins of different origin, their pathogenic role is described, with special attention to the genetic background of these agents. the possible use of enterotoxins for active immunization purposes is also discussed. | 1979 | 399581 |
| [activity of various enzymes in the blood, liver, intestines and kidneys in spontaneous colibacteriosis of piglets]. | the purpose of the studies was to determine the activity of enzymes in the serum and pig organs with colibacteriosis in the form of oedema and stomach-intestines disease playing a diagnostic role in the determination of the organ damage degree. studies were carried out on 29 pigs. the activity of lap, gpt, got, am, fdpa, lp, ap and acp was determined in the serum liver, empty intestines and kidneys of the diseased and control pigs. it resulted from the experiments that in the serum of all the di ... | 1979 | 400185 |
| factors contributing to postweaning diarrhoea in a large intensive piggery. | some aspects of postweaning diarrhoea (pwd) in a piggery during the first week after early weaning were investigated. a haemolytic enterotoxigenic strain of e. coli (o149:k88:h10) was regularly recovered from piglets with pwd while rotavirus was demonstrated on a number of occasions. prior to weaning piglets were either free of, or shed very few, haemolytic e. coli in their faeces. however, all piglets were excreting haemolytic e. coli between 5 and 7 days after weaning. the role of rotavirus in ... | 1980 | 6252883 |
| [nuclear translocation and effect of camp-dependent protein kinase on transcription]. | the influence of camp-dependent pig brain protein kinase and its subunits on transcription in vitro was studied. the increase in the template activity of chromatin isolated from the nuclei after treatment with the catalytic subunit was observed. the regulatory subunit of protein kinase was found to increase the number of binding sites for rna polymerase on chromatin. the camp-dependent pig brain protein kinase was found to phosphorylate the sigma-factor of escherichia coli rna polymerase. this p ... | 1980 | 6260240 |

| antibacterial antibodies in swine colostrum. | antibacterial antibody activities were examined in 138 samples of swine colostrum by o-agglutinin test with serotypes of escherichia coli (o-6, 0-45, 0-81, 0-83, 0-115, 0-138, o-139, and o-126), salmonella typhimurium, and salmonella cholerae suis. the mean agglutinin titer of e coli o-83 was the highest; e coli o-115 was next highest. the mean agglutinin titer of s cholerae suis was lowest; s typhimurium was next to lowest. correlation coefficients among these o-agglutinin titers were between 0 ... | 1980 | 6989301 |
| influence of oral antibiotics on resistance and enterotoxigenicity of escherichia coli. | three groups of five piglets were formed and 1390 escherichia coli isolates were obtained during the 45-day period of observation. one of the groups received feed without antibiotic whereas the second received feed containing 100 ppm neomycin and the third feed with 100 ppm neomycin plus 100 ppm tetracycline. rectal swabbings for bacterial isolation were repeated ten times, twice during an adaptation period and eight times during the treatment period. resistance among the isolates to tetracyclin ... | 1980 | 6994861 |
| the effects of laboratory animal diets on the potency tests of bacterial vaccines. | comparative studies of the responses elicited by mice fed on pcd and ffg diets to a number of bacterial vaccines have shown a significant reduction in the immune response to tetanus toxoid but not to clostridium septicum toxoid and increased resistance to challenge with e. coli and syngeneic tumour cells but not to pasteurella multocida. these differences cannot readily be explained in terms of differences between the identifiable constituents of the diets and illustrte the dangers of vaccine po ... | 1980 | 6995215 |
| identification of a carbohydrate receptor recognized by uropathogenic escherichia coli. | earlier investigations have shown that pyelonephritic escherichia coli specifically recognize and bind to carbohydrate structures correlated to the p blood group antigens. these findings are confirmed and extended in this study. twenty-two of 23 nonselected e. coli strains from children with acute febrile pyelonephritis failed to agglutinate human erythrocytes lacking the antigens within the p blood group system. only one of 32 faecal isolates exhibited this specific agglutinating property. the ... | 1980 | 6997213 |
