| leishmania tropica: intraspecific polymorphisms in lipophosphoglycan correlate with transmission by different phlebotomus species. | lipophosphoglycan (lpg) is a dominant surface molecule of leishmania promastigotes which has been shown to be critical for parasite-sand fly vector interactions. to provide additional evidence for its importance in transmission, the lpgs from three leishmania tropica strains that differ in their capability to infect sand flies, were biochemically characterized. one of these strains, iser/il/98/lrc-l747, was isolated from a phlebotomus sergenti female collected in the judean desert close to jerus ... | 2004 | 15208044 |
