rapid identification of cultured mycobacterium tuberculosis with a panel of monoclonal antibodies in western blot and immunofluorescence.this paper describes the identification of cultured mycobacteria with a panel of monoclonal antibodies directed against species-specific epitopes in a western blot (wb) test and in an immunofluorescence test (ift). in wb, we identified mycobacteria of the mycobacterium tuberculosis complex (m. tuberculosis, m. africanum, m. bovis, m. bovis bcg, and m. microti) with 10(8) bacteria. in the ift, we identified mycobacteria of the m. tuberculosis complex, the m. avium complex (m. avium, m. intracellu ...19892483276
a 180-kilodalton protein from mycobacterium tuberculosis defined by a human t cell clone.a high molecular weight protein from mycobacterium tuberculosis (m. tuberculosis) has been identified, that is recognized by peripheral blood mononuclear cells from several tuberculous patients and by a t cell clone derived from a patient with tuberculous pleurisy. purification of this fraction demonstrated biological activity to reside in a 180-kda protein component. this mycobacterial protein appears to exist in some, but not all mycobacteria as the clone reacts to m. tuberculosis, bcg m. kans ...19892483413
the origin and specificity of intrathecal igg in chronic relapsing experimental allergic encephalomyelitis.the source of igg in the cerebrospinal fluid (csf) in guinea pigs with chronic relapsing experimental allergic encephalomyelitis (cr-eae) was investigated using quotient analysis of total igg and albumin concentrations and by computing csf-plasma ratios of specific igg concentrations. increased blood-csf barrier (b-csfb) permeability was shown by elevated albumin quotients in both relapse and remission phases of cr-eae and intrathecal production of igg was indicated by raised ratios of igg to al ...19892485078
[congenital tuberculosis].congenital tuberculosis is a rare disease of variable incidence in accordance with prevalence of the disease in the general population. we report a case in a neonate born prematurely, whose mother presented with miliary tuberculosis diagnosed in the puerperal period. the newborn had no contact with his mother after delivery, neither with other infected people. the clinical picture consisted mainly in signs and symptoms of septicaemia of gradual onset. mycobacterium tuberculosis was isolated from ...19892485525
homology of the 70-kilodalton antigens from mycobacterium leprae and mycobacterium bovis with the mycobacterium tuberculosis 71-kilodalton antigen and with the conserved heat shock protein 70 of eucaryotes.two lambda gt11 recombinant clones, jkl2 and jkl15, each containing an insert coding for part of the highly immunogenic 70-kilodalton (kda) protein antigen, were isolated from a mycobacterium leprae genomic library by immunoscreening with the monoclonal antibody l7. clone jkl2 contained the largest insert, 2.3 kilobase pairs. nonoverlapping fragments of this insert were used as probes and showed strong hybridization to a number of mycobacterium tuberculosis-lambda gt11 recombinants producing pro ...19892491836

evaluation of an enzyme-linked immunosorbent assay (elisa) using an igg antibody to mycobacterium tuberculosis antigen 5 in the diagnosis of active tuberculosis in children.an enzyme-linked immunosorbent assay (elisa) using mycobacterium tuberculosis antigen 5 has been evaluated as a serodiagnostic test for active tuberculosis in children. forty children of either sex, ages 1 to 14 yr, were studied, including 21 bacteriologically confirmed tuberculous patients and 19 control subjects who were evaluated for tuberculosis and found to be free of disease. at a 1:20 dilution, the test showed a sensitivity of 0.857 and a specificity of 1.000, with an accuracy value of 0. ...19892493761
influence of bcg-induced immunity on the bactericidal activity of isoniazid and rifampicin in experimental tuberculosis of the mouse and guinea-pig.the influence of previous bcg vaccination on the bactericidal activity of isoniazid and rifampicin has been studied using serial counts of viable tubercle bacilli in the spleens and lungs of mice and guinea-pigs infected intravenously with m. tuberculosis, strain h37rv. in mice, bcg vaccination decreased the bactericidal activity of isoniazid in the spleen, but did not affect its activity in the lungs, where immunity is less strongly expressed. bcg did not influence the bactericidal activity of ...19892493801
inhibition by normal human serum of mycobacterium avium multiplication in cultured human macrophages.normal human serum used as a protein supplement in rpmi 1640 medium inhibited growth in blood-derived human macrophages (mp) of virulent mycobacterium avium serovars 4 and 8, derived from patients with acquired immunodeficiency syndrome, but not virulent mycobacterium tuberculosis. a defined serum substitute (ss) promoted the intramacrophage growth of m. avium but not of m. tuberculosis. the effects of serum or ss were measured by counting viable bacteria in lysates of the mp at 0, 4, and 7 days ...19892494117
[therapeutic efficacy of the principal antitubercular drugs: an evaluation by antibiogram].pulmonary and extrapulmonary tuberculosis is still encountered in clinical practice, sometimes in forms that are difficult to categorize nosographically. in this study, the therapeutic efficacy of the 6 main antitubercular drugs (rifampicin, streptomycin, isoniazide, ethambutol, kanamycin, para-aminosalicylic acid) in 20 patients with early tb of the lungs was assessed on the basis of antibiogram findings. para-aminosalicylic acid was found to be the least effective; isoniazide, rifampicin and s ...19892494591
further specific triglycosyl phenol phthiocerol diester from mycobacterium tuberculosis.mono- and two-dimensional 1h-nmr allowed the structural elucidation of a glycolipid belonging to the phenolic mycosides series: 2,3,4-tri-0-methyl fucopyranosyl (alpha 1----3) rhamnopyranosyl (alpha 1----3) rhamnopyranosyl (alpha 1----dimycocerosyl) phenol phthiocerol. it shares with the major phenolic glycolipid the two terminal sugar residues, suggesting its potential antigenicity. the glycolipid may also represent an intermediate in the biosynthesis of the major one.19892495024
ldh isoenzyme as a tool for the identification of mycobacteria.using polyacrylamide gel electrophoretic technique, the lactate dehydrogenase (ldh) isoenzyme patterns have been studied in four slow growing mycobacteria viz. mycobacterium tuberculosis, m. avium, m. microti, and m. bovis and four rapid growing mycobacteria viz. m. fortuitum, m. parafortuitum, m. thermoresistible and m. diernhoferi. each mycobacterial species exhibited distinct isoenzyme pattern for ldh.19892495332

features in hospitalized patients with symptom-detected or radiologically-detected pulmonary tuberculosis.to compare features of tuberculosis detected either clinically or radiologically, we studied 498 patients hospitalized for tuberculosis. tuberculosis was less frequently radiologically-detected in patients over 65 yrs old (p less than 0.01) and in directorial staff and inactive subjects (p less than 0.0001). pleural effusion and radiological cavities were more frequent in the symptom-detected group, but half of the radiologically-detected patients had clinical symptoms which could have led to th ...19892495981
mycobacterial esophagitis in aids.a patient with acquired immune deficiency syndrome (aids) who presented with dysphagia is described. barium swallow demonstrated diffuse esophagitis with longitudinal ulceration and sinus tracts to the mediastinum. mycobacteria were seen on esophageal biopsies and mycobacterium tuberculosis was cultured from a pleural effusion. mycobacterial esophagitis should be considered in the differential diagnosis of esophagitis in aids, particularly when sinus tracts are demonstrated.19892496001
defects in sera from acquired immunodeficiency syndrome (aids) patients and from non-aids patients with mycobacterium avium infection which decrease macrophage resistance to m. avium.some characteristics of the sera and macrophages (mp) of human immunodeficiency virus (hiv)-infected patients which might contribute to their unusual susceptibility to mycobacterium avium infection were studied. cultures of patient peripheral blood mp in medium supplemented with their sera or normal subject sera were infected with m. avium and compared with similar cultures of normal mp. intracellular mycobacterial replication was measured in the infected mp by cfu counts of the bacteria made fr ...19892496029
immune mechanisms in the pathogenesis of pulmonary tuberculosis.the pathogenesis of pulmonary tuberculosis and the beneficial and detrimental effects of the host's cell-mediated immune response in this disease are reviewed. tubercle bacilli are hardly facultative intracellular pathogens that live and multiply in nonactivated macrophages. before tubercle bacilli can be destroyed by macrophages, these cells must be activated by t lymphocytes and their lymphokines. such activation is the essence of cell-mediated immunity. cell-mediated immunity also has a detri ...19892496453
regulation of t cell responsiveness against mycobacterial antigens by hla class 2 immune response genes.helper t lymphocytes can only recognize mycobacterial antigens when they are presented by hla class 2 molecules. thus, these molecules may play an important role in the regulation of the immune response against mycobacteria. in this paper it is demonstrated that the t cells from individuals with different hla class 2 molecules react to different mycobacterial antigens. these data indicate that hla class 2 molecules are the products of immune response (ir) genes for mycobacteria. such genetically ...19892496455
a cloned dna fragment for identification of mycobacterium tuberculosis.the identification of mycobacterium tuberculosis is a lengthy process. attempts were made to develop a more rapid, specific, and sensitive assay for identifying tubercle bacilli in biologic specimens by differentially screening plasmid libraries of sau3ai-digested m. tuberculosis h37rv (atcc 25618) dna with homologous and heterologous dna for clones that hybridized strongly with m. tuberculosis dna alone. three clones, pmtb1, pmtb2, and pmtb3, were selected for further study. southern analysis i ...19892496456
serology of mycobacteria: characterization of antigens recognized by monoclonal antibodies.analysis of the antibody response to mycobacterial extracts has identified a limited set of proteins that are recognized as immunodominant in the balb/c strain of mice. detailed characterization has revealed that several of these antigens are homologues of proteins known to be induced in response to environmental stress stimuli in other prokaryotic and eukaryotic cell types. it is proposed that differential gene expression may play a role in determining which antigens are recognized during infec ...19892496457
approaches to the development of new antituberculosis drugs.in the last two decades, no new major antituberculosis drug has been developed. although dramatic improvements in chemotherapy for tuberculosis have been achieved through careful studies of drug regimens, there is still a need for new agents that are highly active. the antimycobacterial drugs used at present in therapy for tuberculosis were obtained by either blind screening or chemical modification of active compounds, with tentative optimization of chemotherapeutic properties. other approaches ...19892496458
new experimental drugs for the treatment of tuberculosis.new antitubercular agents are needed for two main purposes: to further simplify therapy (through reductions in the number of medicaments used, the number of doses administered, and the duration of treatment required), thus facilitating supervision and improving compliance, and to combat resistant mycobacteria. reduction in the number of medicaments has been achieved by combining two or more drugs in a single tablet while retaining a degree of bioavailability similar to that of the single compone ...19892496459

bacteriological studies of tuberculosis in sidamo regional hospital.all of the 104 strains isolated from tuberculosis patients in sidamo regional hospital were identified as m. tuberculosis. primary single drug resistance to isoniazid and streptomycin was represented by two strains in each case. four strains showed double drug resistance to the same drugs. none were resistant to thiacetazone, rifampicin and ethambutol.19892502390
streptococcal cell wall arthritis. passive transfer of disease with a t cell line and crossreactivity of streptococcal cell wall antigens with mycobacterium tuberculosis.primary lymph node cells derived from streptococcal cell wall arthritic rats or those derived from adjuvant arthritic rats proliferated in response to cell wall antigens derived from either streptococcal cell walls or those from m. tuberculosis. in addition, two t cell lines have been isolated from lymph nodes of rats during the chronic phase of streptococcal cell wall arthritis. these t cell lines transfered clinical disease to naive syngeneic irradiated recipients, and they proliferated in the ...19892502600
tuberculous arthritis presenting as tophaceous gout.a 73-year-old black man with chronic gout presented with a 1 1/2 year history of a swollen painful left wrist. two draining ulcers over the ventral aspect of his wrist and radiographic changes of the affected area suggested chronic gouty arthritis, but culture of the fluid from the wrist grew mycobacterium tuberculosis. this case extends the list of infectious agents producing septic arthritis in patients with gout to include mycobacterium tuberculosis. the need for culture evaluation of joint f ...19892502626

[secondary multiple resistance during treatment of tuberculosis].a case of severe bilateral pulmonary tuberculosis is presented. during treatment, the patient developed resistance to a total of six drugs. the reasons were poor patient compliance and incorrect treatment. in order to avoid problems with resistant strains, it is important that the departments undertaking treatment have experience with the medicinal treatment and understanding of the problem of compliance. if it is not possible to carry out satisfactory treatment, the patient must be referred to ...19892502875
[the mode of action of antimycobacterial benzylamines].the antimycobacterial effects of benzylamines are not related to an inhibition of aminoacyl-trna synthetases.19892502972
lipoarabinomannan from mycobacterium tuberculosis induces the production of tumour necrosis factor from human and murine macrophages.we show here that purified lipoarabinomannan (lam) from mycobacterium tuberculosis can cause the release of tumour necrosis factor (tnf) in vitro from human blood monocytes and activated mouse peritoneal macrophages, and the production of tnf in vivo in mice pretreated with propionibacterium acnes, with a potency comparable to that of lipopolysaccharide (lps) from gram negative bacteria. like lps, lam binds to polymyxin b. we confirmed that its activity was distinct from any contaminating lps an ...19892503277
rapid diagnosis of tuberculous meningitis by elisa to detect mycobacterial antigen and antibody in the cerebrospinal fluid. 19892503566
[effect of various peptides on the growth of mycobacterium tuberculosis].ten oligopeptides containing asparagine, glutamic acid, leucine or alanine on growth of bacillus tuberculosis were tested. the experiments were performed on as medium free of peptones. bacterial suspensions were inoculated and the number of colonies and rapidity of bacilli growth under an influence of peptides tested was compared. out of peptides studied and their different combinations the best turned to be combination of 0.01% glutathione +0.002% gly-asn + 0.0033% leu-gly. this combination all ...19892503665
biochemical and antigenic characterization of the mycobacterium tuberculosis 71kd antigen, a member of the 70kd heat-shock protein family.a 71 kilodalton antigen from mycobacterium tuberculosis is recognized by antibodies and by t lymphocytes during infection (britton et al., 1986a). partial sequence analysis indicates a relationship between this antigen and the highly conserved family of 70-kilodalton heat shock proteins (hsp70) (young et al., 1988). biochemical and serological characterization of the protein confirms its membership of the hsp70 gene family, and metabolic labelling demonstrates that it is a major component of the ...19892503672
non-cultivable mycobacteria in ulcers of the skin.in biopsies of 54 patients suffering from chronic dermatological lesions (mostly ulcers of the skin) acid-fast bacilli were found in 14. in these 14 cases in 4 were lesions caused by m. tuberculosis, in 1 the lesion was caused by m. avium-intracellulare, in 1 the lesion was caused by m. fortuitum and in 2 the lesions were caused by non-cultivable mycobacteria (feldmann-hershfield ulcer?). in 2 cases the cultures were heavily contaminated, and the diagnosis remained uncertain. in the remaining 4 ...19892503961
identification of mycobacterial antigens for "elisa" serology in the diagnosis of leprosy and tuberculosis.using an immunoblotting assay (imba), several immuno-crossreactive antigenic components (imcrac-myc) have been identified in the whole sonicates of m. bovis-bcg, and m. tuberculosis (mtb) and m. leprae (ml) whereby the sera of 100% lepromatous leprosy (l-lep) reacted to 29/33 kd doublet and that of 100% tuberculoid leprosy (t-lep) reacted to 64 kd bands. the antigens upon purification from mtb sonicates were used in a direct elisa to measure antibody isotypes in the sera from l-lep, t-lep, healt ...19892503964

evaluation of a phenolglycolipid antigen (pgl-tb 1) from m. tuberculosis in the serodiagnosis of tuberculosis: comparison with ppd antigen.sera from 38 tuberculous patients and 62 healthy controls (31 ppd skin test positive and 31 negative) were assayed, by enzyme-linked immunosorbent assay (elisa), to test the activity of igg and igm antibodies against purified protein derivative (ppd) antigen and a phenolglycolipid antigen (plg-tb 1) isolated and purified from mycobacterium tuberculosis strain canetti. using ppd antigen, the sensitivity and specificity were respectively, 50 and 93.5% for igg and 71.1 and 59.7% for igm antibody ac ...19892504014
serological specificity of mycobacterium tuberculosis glycolipids.six glycolipid fractions can be extracted from lipid crude extracts of canetti type strains of m. tuberculosis. among these fractions are two phenolglycolipids. the major component is a triglycosyl phenolphthiocerol dimycocerosate (pgl-tb 1) and the second is a monoglycosyl diacyl phenolphthiocerol identical to mycoside b of m. bovis. similar glycolipid compounds can also be found in wild strains of m. tuberculosis recently isolated from tuberculous patients. one of these compounds has been iden ...19892504016
mixed mycobacterial cultures--occurrence in the clinical laboratory.during a 2-year period we observed at our institution 22 mixed mycobacterial cultures among a total of 991, representing 20 patients. we found no evidence of double infection. mixed cultures frequently contained saprophytic organisms. our experiments have shown that subculturing, especially into liquid media, can significantly change the relative quantities of cfu's present in mixed cultures. we believe that the use of agar media is useful for the recognition of mixed cultures.19892504179
mycobacterium tuberculosis cervical adenitis. diagnosis and management.cervical adenopathy as the sole presentation of tuberculosis is seen infrequently in the pediatric age group. despite modern treatment and public health measures, tuberculous cervical adenitis persists, and its prompt diagnosis and treatment are important from both a clinical and preventive health perspective. the authors report five cases of children with ages ranging from 8 to 17 years, in whom cervical adenitis was the only presentation of infection with mycobacterium tuberculosis. the clinic ...19892504530
direct identification of mycobacterium tuberculosis, mycobacterium avium, and mycobacterium intracellulare from amplified primary cultures in bactec media using dna probes.dna probes (gen-probe, san diego, calif.) directed at the mycobacterium tuberculosis complex and mycobacterium avium-m. intracellulare complex were used to identify acid-fast bacilli directly from specimens grown in bactec 12b bottles (becton dickinson and co., towson, md.). clinical specimens were inoculated directly or after decontamination into a bactec 12b bottle, middlebrook 7h11 agar, and lowenstein-jensen medium. conventional media were incubated at 37 degrees c in 5% co2 and examined wee ...19892504770
the importance of penetration of antimicrobial agents into cells.phagocytes may shelter intracellular pathogens from the otherwise lethal effects of many antibiotics. research in conditions such as chronic granulomatous disease, tuberculosis, legionellosis, and experimental staphylococcal infection underscores the principle that an antibiotic must enter the cell in order to be active against an intracellular microorganism. demonstrating entry does not guarantee activity, however. the microenvironment and intracellular distribution of the pathogen and antimicr ...19892504811
preparation and properties of monoclonal antibodies against mycobacterium tuberculosis.the above mentioned monoclonal antibodies of idiotype igg 3/kappa against tmc 120 and tmc 107 strains of m. tuberculosis were prepared by fusion of mouse myeloma line fo cells with splenocytes balb/c of mice immunized with complex antigens. these were prepared from the bacterial mass previously inactivated with gamma-rays radiation, and applied without mycobacterial adjuvant agent. species specificity of both monoclonal antibodies was determined by elisa testing and dot blot test. the potential ...19892504816
