spectrum of viral pathogens in blood of malaria-free ill travelers returning to canada.malaria is the most common specific cause of fever in returning travelers, but many other vectorborne infections and viral infections are emerging and increasingly encountered by travelers. we documented common and emerging viral pathogens in malaria-negative specimens from ill travelers returning to canada. anonymized, malaria-negative specimens were examined for various viral pathogens by real-time pcr. samples were positive for herpes simplex viruses 1 or 2 (n = 21, 1.6%), cytomegalovirus (n ...027089008
diabetes, epstein-barr virus and extranodal natural killer/t-cell lymphoma in india: unravelling the plausible nexus.the international diabetes federation diabetes atlas estimates a staggering 590 million people affected with diabetes mellitus (dm) within the next two decades globally, of which type 2 dm will constitute more than 90%. the associated insulin resistance, hyperinsulinemia, and hyperglycemia pose a further significant risk for developing diverse malignant neoplasms. diabetes and malignancy are multifactorial heterogeneous diseases. the immune dysfunction secondary to type 2 diabetes also reactivat ...027051150
comparative study of cultured burkitt tumor cells by immunofluorescence, autoradiography, and electron microscopy.cultured burkitt cells were examined by immunofluorescence, autoradiography, and electron microscopy in an effort to identify the stainable cells with those harboring herpes-type virus particles. immediately after a 2-hr pulse of (3)h-thymidine, from 30 to 60% of the cells revealed heavy nuclear labeling. in most cases the grains were evenly dispersed, but in about 3 to 5% the grains showed a focal distribution and occasionally they extended into the cytoplasm. such nuclear foci were rarely seen ...19674316231

effect of arginine-deficient media on the herpes-type virus associated with cultured burkitt tumor cells.after incubation at 37 c for 2 or more days, basal medium eagle (bme) supplemented with 25% fetal calf serum (fcs) was not able to support adequate growth of eb3 and other lines of burkitt tumor cells. the medium did, however, increase, by a factor of about 10, the number of cells synthesizing herpes-type virus with which the cultures were persistently infected. not every lot of fcs produced these effects, nor were these effects seen when bme and fcs were incubated separately for 7 days before t ...19684316020
relation between epstein-barr viral and cell membrane immunofluorescence of burkitt tumor cells. i. dependence of cell membrane immunofluorescence on presence of eb virus.a comparison was made of the immunofluorescence tests for detection of cell membrane and epstein-barr virus antigens in cells from burkitt tumor biopsies or continuous cultures derived therefrom. on the whole, cell membrane fluorescence in established lines appeared to depend not only upon the presence of ebv but to a considerable degree also upon the extent of the persistent viral infection. there was no constant relationship, however, between the results of the two tests and exceptions to the ...19684878906

transformation and chromosome changes induced by epstein-barr virus in normal human leukocyte cultures.three separate attempts to establish long-term leukocyte cultures from the peripheral blood of a healthy adult who had no evidence of previous infection with epstein-barr virus were consistently unsuccessful. on the other hand, in vitro infection of buffy-coat cells of this donor with epstein-barr virus resulted in blastoid transformation of the lymphocytes and long-term growth potential. the transformation was accompanied by major chromosome changes. the significance of these findings in relati ...19695259761

relation between epstein-barr viral and cell membrane immunofluorescence in burkitt tumor cells. 3. comparison of blocking of direct membrane immunofluorescence and anti-ebv reactivities of different sera.sera from patients with burkitt's lymphoma (bl), infectious mononucleosis (im), carcinoma of the postnasal space (ca pns), and various controls were investigated for antibodies against the epstein-barr virus (ebv) by immunofluorescence on acetone-fixed smears (5) and for antibodies against the distinctive antigenic sites expressed on the surface of viable lymphoblastoid cells within ebv-carrying culture lines (1). the latter were studied by the blocking of direct membrane staining with fitc-conj ...19694886044
relation between epstein-barr viral and cell membrane immunofluorescence in burkitt tumor cells. iv. differentiation between antibodies responsible for membrane and viral immunofluorescence.previous reports (1, 2) have established that the expression of certain distinctive membrane antigen(s) on the surface of burkitt's lymphoma (bl) and infectious mononucleosis (im) cells is dependent on the presence of epstein-barr virus (ebv) in the cell line. the investigations reported here provide evidence that antibodies directed against ebv antigens, as revealed by the immunofluorescence test on acetone-fixed smears (8), and the membrane reactive antibodies, although often present in the sa ...19694886045

relation between neutralization of epstein-barr virus and antibodies to cell-membrane antigens-induced by the virus.the neutralization of epstein-barr virus (ebv) infectivity by sera with known antibody activities against ebv-associated antigens was investigated in experimentally infected raji and rpmi 64-10 cells. antibodies against ebv-induced cell-membrane antigens were apparently responsible for neutralization of viral infectivity. antibodies against ebv capsid antigens and ebv-induced early antigens were not involved. the implication of these results on the relationship of the membrane antigens to the in ...197018605425

epstein-barr viral antigen in single cell clones of two human leukocytic lines.a method was devised for obtaining single cell clones of human leukocytic cell lines in the presence of a human placental cell feeder layer. clones of two lines, ls-b and eb(3), which contain epstein-barr viral (ebv) antigen in approximately 1% of cells were tested for ebv antigen. since all eb(3) clones and ls-b clones contained ebv antigen, it is concluded that in vitro ebv genome is associated with all of the cells.19704320703

differential reactivity of human serums with early antigens induced by epstein-barr virus.inoculation of 64-10 or raji cultures with epstein-barr virus derived from the hri-k clone of the p3j burkitt's lymphoma line caused abortive infections in most of the lymphoblastoid cells with synthesis of "early antigens" but few, if any, capsids. antibodies to early antigens were detected by indirect immunofluorescence in serums of many patients with infectious mononucleosis, burkitt's lymphoma, or nasopharyngeal carcinoma. these antibodies were rarely present in other serums even though some ...19704316788
