| epidemiologic aspects of american visceral leishmaniasis in an endemic focus in eastern venezuela. | an endemic focus of american visceral leishmaniasis (avl) in eastern venezuela has been evaluated in terms of patients (n = 48), immunologic reactivity to leishmania in household contacts (n = 187) and neighborhood controls (n = 170), detection of leishmania (l. donovani complex) in dogs and wild animals by the polymerase chain reaction (pcr) and characteristics of the sandfly population. the male:female ratio of patients was 1.18:1; 89.6% were < or =12 years old. serologic reactivity was signif ... | 1999 | 10674675 |
| a mr 90 000 surface polypeptide of trypanosoma cruzi as a candidate for a chagas' disease diagnostic antigen. | trypanosoma cruzi (peru strain) trypomastigotes and epimastigotes were biosynthetically labeled with [35s]methionine, and the proteins were analyzed by two dimensional polyacrylamide gel electrophoresis (2d-page). 2d-page analysis of the trypomastigotes showed a complex array of polypeptides with distinct clusters at mr 88 000-92 000, isoelectric point (pi) 5.6-6.0, and mr 72 000-76 000, pi 5.6-5.8. 2d-page analysis of the epimastigotes did not show the cluster of polypeptides at mr 90 000. when ... | 1985 | 3932849 |
