Cutaneous as well as visceral leishmaniasis has been previously report
ed in Egypt. The former clinical manifestation is attributed to Leishm
ania major, the latter to L. infantum. In this study, L. tropica was i
solated from an Egyptian labourer returning from Saudi Arabia. Amastig
otes were detected by both Giemsa staining and indirect immunofluoresc
ence using rabbit anti-gp63. Promastigotes from Schneider's medium wer
e typed isoenzymatically as L. tropica. In view of the emerging threat
of visceralization of L. tropica, the potential risk for its transmis
sion in Egypt is discussed.
