| immunological crossreactivity of the mycobacterium leprae cfp-10 with its homologue in mycobacterium tuberculosis. | mycobacterium tuberculosis culture filtrate protein-10 (cfp-10) (rv3874) is considered a promising antigen for the immunodiagnosis of tuberculosis (tb) together with early secreted antigens of m. tuberculosis (esat-6). both esat-6 and cfp-10 are encoded by the rd1 region that is deleted from all tested m. bovis bacille calmette-guérin (bcg) strains but present in m. leprae, m. tuberculosis, m. bovis, m. kansasii, m. africanum and m. marinum. in this study, the homologue of cfp-10 in m. leprae (m ... | 2004 | 14723623 |
| under-explored experimental topics related to integral mycobacterial vaccines for leprosy. | many leprosy vaccine studies have utilized live or killed whole mycobacteria, such as bacille calmette-guérin, indian cancer research center (icrc) bacilli and mycobacterium w either alone or in combination with killed mycobacterium leprae. for bacille calmette-guérin, the vaccine dose is generally that which gives the largest delayed-type hypersensitivity response with minimal side effects. the doses of other integral mycobacterial vaccines appear to be arbitrarily chosen. hypotheses governing ... | 2003 | 14711362 |
| [neurological manifestations of leprosy]. | leprosy, also known as hansen's disease, is a chronic, infectious disease caused by mycobacterium leprae. bacilli localize preferentially in the skin and peripheral nerves and have a propensity to cause nerve damage. the resulting disability has caused great suffering for victims in many countries. despite recent advances in the immunopathogenesis, epidemiology and prognostic factors of leprosy nerve damage, many aspects of the disease have remained enigmatic. the spectrum of clinical and pathol ... | 2003 | 14710019 |
| leprosy: a primer for canadian physicians. | leprosy is a rare but serious infectious disease caused by mycobacterium leprae. while global prevalence of the disease is decreasing, increasing rates of immigration from countries where leprosy is endemic have led to the recognition of this illness in north america. classically, leprosy presents as hypopigmented cutaneous macules along with sensory and motor peripheral neuropathies, although the clinical manifestations vary along a disease spectrum. in addition to primary infection, patients m ... | 2004 | 14707226 |

| effects of anti-endothelial cell antibodies in leprosy and malaria. | as a result of damaging endothelial cells (ecs), mycobacterium leprae triggers the production of antibodies (abs). these anti-ec abs (aecas) can be divided into two types. the first type nonspecifically reacts with components of the cytosol (cy) and can be detected by enzyme-linked immunosorbent assay (elisa). the second specifically reacts with the ec membrane (mb) and requires fluorescence-activated cell sorter (facs) analysis to be detected. the presence of both types of aecas was determined ... | 2004 | 14688109 |
| anti-mycobacterial immunity induced by a single injection of m. leprae hsp65-encoding plasmid dna in biodegradable microparticles. | a single sub-cutaneous injection of a plasmid dna encoding a mycobacterial heat shock protein 65 (hsp65) entrapped in biodegradable poly(lactic-co-glycolic acid) microspheres produced high titers of antibodies, measured 5 months after the injection in balb/c mice. splenocytes secreted ifn-gamma and exerted an anti-bacterial effect on macrophages infected in vitro with mycobacterium tuberculosis. the results are encouraging with regard to obtaining good compliance and vaccination coverage with ca ... | 2003 | 14687708 |
| nk cells modulate the cytotoxic activity generated by mycobacterium leprae-hsp65 in leprosy patients: role of il-18 and il-13. | protection against intracellular pathogens such as mycobacterium leprae is critically dependent on the function of nk cells at early stages of the immune response and on th1 cells at later stages. in the present report we evaluated the role of il-18 and il-13, two cytokines that can influence nk cell activity, in the generation of m. leprae-derived hsp65-cytotoxic t lymphocytes (ctl) from peripheral blood mononuclear cells (pbmc) of leprosy patients. we demonstrated that il-18 modulates hsp65-in ... | 2004 | 14678270 |
| [hansen's disease in the laboratory]. | a physical doctor with a phd in pathology, euzenir nunes sarno studies the immunology factors of hansen's disease, one of the oldest chronic infections and that is an exclusively human disease. staff member of an ambulatory that has become a reference on the disease in brazil with 220 to 250 new patients per year, euzenir emphasizes that the fact one cannot cultivate mycobacterium leprae brings about some everlasting questions in relation to the transmission of and the sensitivity to the disease ... | 2003 | 14650417 |
| lepromatous phlebitis of the external jugular vein. | mycobacterium leprae (m leprae), the causative agent of hansen's disease, is endemic in many areas of asia, sub-saharan africa, south and central america, the pacific islands, and the philippines. the spectrum of clinical disease is dependent on the patient's cell-mediated immunity and might range from localized anesthetic patches or plaques to disseminated disease. if undiagnosed, progression with damage to the involved sensory and motor nerves might occur. lepromatous vasculitis occurs most co ... | 2003 | 14639414 |
| lepromatous leprosy in a heart transplant recipient. | northern louisiana is not an area for indigenous cases of leprosy. limited data are available on the occurrence of leprosy in organ transplant recipients. no cases have been reported in heart transplant recipients. mr j.r. is a 68-year-old man from shreveport, louisiana. he underwent orthotopic heart transplantation in march 1996. he presented in march 2000 with a maculopapular skin rash and intermittent hand swelling for 5 months. he also complained of intermittent burning of his feet for a yea ... | 2003 | 14629293 |
| a second case of multidrug-resistant mycobacterium leprae isolated from a japanese patient with relapsed lepromatous leprosy. | emergence of drug resistant strains of mycobacterium leprae was reported soon after the introduction of dapsone (diamino-diphenyl sulphone, dds) for leprosy treatment (6, 10, 11). three cases of multidrug-resistant strains of m. leprae have been reported recently (2, 8, 9, 13). in order to prevent multiple drug resistant strains of m. leprae from developing, current leprosy control strategies are based on early detection of cases and treatment with multidrug therapy (mdt) as recommended by the w ... | 2003 | 14608820 |
| electron microscope appearance of lepromatous footpads of nude mice [corrected]. | footpad lesions of 3 nude mice infected by mycobacterium leprae were studied at 9, 12, and 14 months after inoculation with light and electron microscope. the lesions were somewhat similar to those found in nodules in polar lepromatous leprosy. striated muscles rather than nerves were the preferred site of the growth of m. leprae. yet, m. leprae were identified in schwann cells and endothelial cells, singly and in clumps. m. leprae filled macrophages, and free m. leprae were found in large numbe ... | 2003 | 14608819 |
| "relatively spared zones" in leprosy: a clinicopathological study of 500 patients. | in this study, clinically all forms of lesions like macules, plaques, and nodules were found in all the "relatively spared zones," except groins. histopathology confirmed that the disease process was established and the acid-fast bacilli were not present as a part of bacteremic settlement. hence, it appears that practically no area on the surface of skin is immune to invasion by m. leprae. however, as the incidence of lesions and afb in these regions is relatively less, especially over axilla an ... | 2003 | 14608818 |
| nodular leprosy of childhood and tuberculoid leprosy: a comparative, morphologic, immunopathologic and quantitative study of skin tissue reaction. | nodular leprosy of childhood (nl) is a benign clinical variant of tuberculoid leprosy that affects breast-feeding infants and children that remained in a highly infected environment. the lesions resolve with complete healing and nl has been considered a manifestation of allergy and congenital immunity to mycobacteria leprae. we studied the tissue reaction, mycobacterial antigen frequency, and the lymphocyte subsets (cd45ro+, cd4+, cd8+, b, nk), dendritic cells (epidermal cd1a+ cells and s100+ de ... | 2003 | 14608817 |
| viability and drug susceptibility testing of m. leprae using mouse footpad in 37 relapse cases of leprosy. | mycobacteria leprae isolates obtained from 37 referral relapse cases of leprosy (37 skin and 10 nerve biopsy samples) received during the years 1994-2001, were tested for viability and drug sensitivity in the mouse footpad. a significant m. leprae yield in the footpads of control mice was obtained, with 32/47 (68%) isolates (from 26 cases) thus confirming viability. of the 28 isolates successfully drug tested, 6 (21%) were resistant to one or more drugs. all except one, were multidrug treated ca ... | 2003 | 14608816 |
| [a case suspected multibacillary leprosy]. | the presence of acid-fast bacilli in the lesion and its positive culture usually provide the diagnosis in cutaneous mycobacteriosis. but in diagnosis of leprosy, characteristic clinico-histopathological findings are so important as the demonstration of the organism, because of the failure to grow mycobacterium leprae in vitro. it is classified in various forms along a spectrum of infectious and immunological symptoms supported by the pathogen-host relationship. the patient was a japanese woman 6 ... | 2003 | 14598642 |
| [a case of paucibacillary leprosy]. | we report a case of leprosy. a 31-old-phillippine female present with 5 month history of an erythematous plaqe on her right neck. examination showed 4 erythematous plaques with her. a histological examination of the skin lesion of hir thigh revealed granulomas around nerve and skin appendages which consist of lymphocytes, epidermoid cells and giant cells. although no acid fast bacilli were not demonstrated by skin biopsy with ziehl-neelsen staining, the mycobacterium leprae-specific dna was dete ... | 2003 | 14598636 |
| nasal carriage of mycobacterium leprae dna in healthy individuals in lega robi village, ethiopia. | the number of registered leprosy patients world-wide has decreased dramatically after extensive application of who recommended multiple drug therapy (mdt). the annual number of new cases has, however, been almost unchanged in several populations, indicating that the infection is still present at community level. nasal carriage of mycobacterium leprae dna was studied in lega robi village in ethiopia. mdt had been applied for more than ten years, and 718 residents over 5 years old were eligible fo ... | 2003 | 14596524 |
| advances in the diagnosis and treatment of leprosy. | leprosy is a chronic infectious disease caused by mycobacterium leprae that mainly affects the skin and peripheral nerves. over recent years, many important advances have been made in developing molecular diagnostics, in identifying highly effective drugs and designing multidrug regimens for treatment, and in unravelling the genomic structure and functions of the leprosy bacillus. using the new information about specific sequences of m. leprae, several gene probes and gene amplification systems ... | 2002 | 14585155 |
| comparison between anti-pgl-i serology and mitsuda reaction: clinical reading, microscopic findings and immunohistochemical analysis. | the lepromin test, serum igm antibodies against mycobacterium leprae and in situ observations of t cell subsets in biopsies of mitsuda reaction using monoclonal antibodies were performed on 44 untreated leprosy patients belonging to various classifications of the disease. the mitsuda reaction was accessed clinically and histologically after 28 days. clinical reading and histological analysis of mitsuda reaction showed good agreement. the high positivity in clinical reading correlated with compac ... | 2003 | 14577472 |
| thalidomide does not modify the ability of cells in leprosy patients to incorporate [3h]-thymidine when incubated with m. leprae antigens. | the immune response in reversal reaction, (rr) and in erythema nodosum leprosum (enl) is characterized in vitro by an enhancement in lymphocyte blast transformation against m. leprae. as thalidomide is an effective treatment for enl, this study assessed the effect of this drug on these phenomena. mononuclear cells from patients attending the clinic at alert and from healthy staff were cultured for 5 days with integral m. leprae (iml), or a modified dharmendra antigen (dhar), or ppd from m. tuber ... | 2003 | 14577465 |
| serology: recent developments, strengths, limitations and prospects: a state of the art overview. | specific antibodies can be used as a surrogate marker for bacterial load in leprosy. tests to detect antibodies can be used for (i) the classification of patients for treatment purposes [most multibacillary (mb) patients are seropositive, most paucibacillary (pb) patients are not], (ii) the prediction of an increased risk of relapse and (iii) the identification of contacts having an increased risk of developing leprosy. with the advent of fast, robust and easy to perform serological tests such a ... | 2003 | 14577464 |
| a tetramer-octamer equilibrium in mycobacterium leprae and escherichia coli ruva by analytical ultracentrifugation. | in the context of the bacterial ruvabc system, ruva protein binds to and is involved in the subsequent processing of a four-way dna structure called holliday junction that is formed during homologous recombination. four crystal structures of ruva from escherichia coli (ecoruva) showed that it was tetrameric, while neutron scattering and two other crystal structures for ruva from mycobacterium leprae (mleruva) and ecoruva showed that it was an octamer. to clarify this discrepancy, sedimentation e ... | 2003 | 14568529 |
| reversal of t cell anergy in leprosy patients: in vitro presentation with mycobacterium leprae antigens using murabutide and trat peptide in liposomal delivery. | mycobacterium leprae, the causative agent of leprosy resides and multiplies within the host monocytes and macrophages, thereby evading host immune system. cell-mediated immune response (cmi) plays a vital role as evidenced from the high cmi in bt/tt (borderline and tuberculoid) patients and conversely low in bl/ll (borderline and lepromatous) patients. in the present study, an attempt was made to immunomodulate the anergized t cells of lepromatous leprosy patients by presenting the mycobacterial ... | 2003 | 14555284 |

| the secret lives of the pathogenic mycobacteria. | pathogenic mycobacteria, including the causative agents of tuberculosis and leprosy, are responsible for considerable morbidity and mortality worldwide. a hallmark of these pathogens is their tendency to establish chronic infections that produce similar pathologies in a variety of hosts. during infection, mycobacteria reside in macrophages and induce the formation of granulomas, organized immune complexes of differentiated macrophages, lymphocytes, and other cells. this review summarizes our und ... | 2003 | 14527294 |
| purification of mycobacterium leprae rna for gene expression analysis from leprosy biopsy specimens. | gene expression analysis in mycobacterium leprae, an obligate intracellular pathogen and the etiologic agent of leprosy, has been hampered by the lack of an efficient method to purify rna from leprosy lesions. therefore to date, transcripts for only a few genes have been identified. we report the use of a single-tube homogenization/rna extraction method that produces enough rna to study the expression of 30 genes from a single skin biopsy specimen of a multibacillary leprosy patient and demonstr ... | 2003 | 14513559 |
| in situ type 1 cytokine gene expression and mechanisms associated with early leprosy progression. | we explored the prognostic value of in situ cytokine patterns in 39 patients with single-skin-lesion paucibacillary leprosy before single-dose therapy, with 3 years of follow-up. interferon (ifn)-gamma, interleukin (il)-12, il-10, il-4, tumor necrosis factor (tnf)-alpha, and macrophage inflammatory protein (mip)-1alpha mrna was quantified in skin biopsy samples at diagnosis, and mycobacterium leprae dna was detected in 51.4% of cases. type 1 immunity predominance with measurable ifn-gamma and un ... | 2003 | 14513423 |
