| characterization of leishmania colombiensis sp. n (kinetoplastida: trypanosomatidae), a new parasite infecting humans, animals, and phlebotomine sand flies in colombia and panama. | characterization of leishmania colombiensis sp.n. is presented, which on the basis of biological and molecular criteria, appears to be a new member of the l. braziliensis complex. a total of nine isolates of the new parasite were made in colombia and panama between 1980 and 1986: two from human cases of cutaneous leishmaniasis, six from phlebotomine sand flies, and one from a sloth. although most closely related to l. lainsoni, l. colombiensis sp.n. is clearly distinguishable from other members ... | 1991 | 1677544 |
| leishmania colombiensis in venezuela. | flagellate parasites isolated in venezuela from bone marrow aspirates of a human (mhom/ve/70/chuao) and a dog (mcan/ve/72/talisman2) were subsequently identified by isozyme analysis as leishmania colombiensis. data are presented describing genetic similarity among panama, colombia, and venezuela populations of this species. | 1993 | 8427384 |
| detection of leishmania causing visceral leishmaniasis in the old and new worlds by a polymerase chain reaction assay based on telomeric sequences. | we present a new polymerase chain reaction assay based on telomeric sequences of leishmania donovani. when this assay was used in dilutions of purified l. donovani dna, a strong amplification signal was observed with 1 fg of dna. in a specificity test that used purified dna from old world and new world leishmania, the assay recognized all parasites isolated from patients with visceral leishmaniasis, except for 2 isolates of leishmania colombiensis from venezuela and 1 isolate from brazil. all le ... | 2001 | 11716117 |
| presence of american cutaneous leishmaniasis vectors surrounding the city of medellín, colombia. | the presence of lutzomyia (helcocyrtomyia) hartmanni, as a vector of leishmania colombiensis and l. columbiana (verrucarum group), recently incriminated in the transmission of leishmaniasis, and l. pia (verrucarum group) are reported for the first time in a periurban area of medellín city. there is thus a risk of leishmaniasis transmission in this town. | 2002 | 12219126 |
| genotypically distinct leishmania colombiensis isolates from venezuela cause both cutaneous and visceral leishmaniasis in humans. | cutaneous leishmaniasis in venezuela has been associated with different leishmania species and the visceral form is frequently related to l. chagasi. however, in this study we have characterized as l. colombiensis by molecular techniques some isolates of leishmania from patients presenting either cutaneous or visceral leishmaniasis. three different molecular markers (two dna and one protein) were used to investigate the diversity among the l. colombiensis isolates. the analysis revealed the isol ... | 2003 | 12809806 |
