“…A suspected reservoir host is the hyrax (Procavia capensis). Leishmania parasites were repeatedly isolated from hyraxes [6,7]; in some CL foci, hyraxes are numerous and peridomestic, and L. tropica was detected in their tissue by PCR [8].…”

“…Leishmania tropica is transmitted anthroponotically in Afghanistan by P. sergenti but in Israel and Kenya is suspected to have a zoonotic transmission cycle with P. sergenti transmitting parasites among populations of rock hyraxes and humans. 16,17 We have not fully clarified the transmission cycle in the Sinai; however, L. tropica was isolated from rodents leaving open the possibility of zoonotic transmission. Phlebotomus sergenti accounted for ≥ 17% of sand flies captured in El Barth.…”

“…The transmission cycle for L. tropica is usually anthroponotic with zoonotic transmission reportedly occurring in some areas. [12][13][14][15][16] Rock hydraxes may serve as the reservoir species in Israel ( Procavia capensis ) and Kenya ( P. johnstoni ). 16,17 Phlebotomus sergenti is an oft implicated sand fly vector in both transmis-sion scenarios and can be found along the Mediterranean coast from Libya, through Egypt, Jordan, Israel, and Iraq.…”

Cutaneous leishmaniasis (CL) is prevalent in the Egyptian Sinai Peninsula and previous research has consistently documented the etiologic agent to be Leishmania major. We report the first isolation of Leishmania tropica from human cases of CL in a Northern Sinai community bordering Palestine. Parasite culturing, real-time polymerase chain reaction (PCR), gene sequencing, and restriction fragment length polymorphism (RFLP) analyses indicate CL cases in this community were caused by either L. major or L. tropica (three cases each). Two wild-caught rodents (Gerbillus pyramidum floweri) were infected with L. tropica. Phlebotomus papatasi sand flies were found harboring L. major, however only non-infected individuals of Phlebotomus sergenti, a vector for L. tropica, were caught. Patients with L. tropica had not traveled from the region in over a year, suggesting these cases are autochthonous. This scenario is consistent with an incursion of L. tropica from bordering countries and raises concerns about expansion of this parasite further into Egypt.

“…Parasites closely related to Le. tropica are certainly zoonotic in Tunisia, Kenya and Namibia, and have been isolated from hyraxes in the last two countries (Sang et al, 1992); this group of zoonotic Le. tropica strains is sometim es separated as Le.…”

Of the 374 species of parasite recorded as naturally infecting Homo sapiens, all but some 40 are zoonotic. A classification of human parasites is proposed, based on the role of H. sapiens in the maintenance of suprapopulations. Categories range from 1, for which man is irrelevant to the persistence of the species, to 4, which includes the small number of host-specific forms. The classification is illustrated by various species of Leishmania, and these are used to illustrate various host-parasite systems. The 'Wells effect' is proposed, to describe the protection of host populations by their parasites.
