    Leishmaniasis, seen in tropical and subtropical regions, is an infectious disease caused by the protozoan parasite Leishmania species. There are three main forms of leishmaniasis: cutaneous, mucocutaneous and visceral leishmaniasis. Cutaneous leishmaniasis (CL) has become an increasing problem as the number of travels around the world increases and people go to work in endemic areas. Turkey has received great numbers of immigrants in recent years, from its neighboring countries like Iraq, Islamic Republic of Iran, Afghanistan, Turkmenistan and the Syrian Arab Republic because of the political instabilities in these countries as well as the job opportunities caused by large-scale development projects undertaken by Turkey. In this report, imported CL cases detected in five truck drivers transporting from Hatay to Turkmenistan, Syria, Saudi Arabia, Iran and Georgia, Uzbekistan and Azarbaijan countries were presented. The patients admitted to Mustafa Kemal University, Faculty of Medicine Dermatology Policlinic, with wound complaints on their bodies were directed to the Department of Parasitology to obtain smear samples from their wounds. The age range of the patients were 38 to 43 years. Patients with wound trail for a period ranging from one month to one year had a number of lesions varying between 2-7 and in all cases, a smear preparation was prepared from the lesions for diagnostic purposes. Clinical material obtained from five patients with pre-diagnosis of CL was firstly examined with Giemsa stain. Samples taken from the patients were inoculated into modified NNN (Novy-MacNeal-Nicolle) medium for the evaluation of the presence of the promastigotes. Promastigotes obtained from the inoculated medium were also genotyped using the ITS1 region. In all of the slides prepared from the clinical material taken from the patients amastigotes were determined. The growth of promastigotes were observed in only three of the clinical specimen inoculated media. The genotyped three species were Leishmania tropica, Leishmania infantum/donovani and Leishmania major. In this study, the importance of support for the diagnosis of different microbiological methods used in the diagnosis of leishmaniasis infection which occurred during the outbreaks of the disease has been put forward. In addition, it was aimed to draw attention to the importance of imported CL cases in our country diagnosed in five truck drivers making transportation from Hatay to Turkmenistan, Syria, Saudi Arabia, Iran, Georgia, Uzbekistan and Azerbaijan. © 2018 Ankara Microbiology Society.

    Do the rodents have a role in transmission of cutaneous leishmaniasis in Turkey?; [Türkiye’de kutanöz leyşmanyaziste kemiricilerin rolü var mı?]
    (Ankara Microbiology Society, 2018) Özbi̇Lgi̇n A.; Çavuş İ.; Yildirim A.; Gündüz C.
    Leishmaniasis is a zoonotic/anthroponotic vector borne parasitic infection which is caused by Leishmania species and transmitted by sand flies (Phlebotomus spp.) The reservoirs of Leishmania species in nature are various wild and domestic carnivores, rodents and human. The aim of this study was to investigate whether the rodents in genera Meriones, Mesocricetus, Rattus and Mus which inhabit in the natural habitat of our country could be natural reservoirs of Leishmania tropica, Leishmania infantum, Leishmania major and Leishmania donovani for cutaneous Leishmaniasis (CL)., The rodents Mus musculus (Balb/C mouse), Mesocricetus auratus (hamster), Meriones unguiculatus (gerbil) and Rattus norvegicus (rat) which are part of the natural habitat in Turkey were used in the study. L.tropica, L.infantum, L.major and L.donovani promastigote isolates obtained from CL patients and cultured in enriched media were injected in the footpads of the animals intradermally using the density of 108 promastigote/ml. The scale of the lesions on the footpads of the animals were measured for 12 weeks. At the end of the experiment, the animals were sacrificed and “touch preparations” were prepared using footpad, liver, spleen and testicles of the sacrified animals and were examined using Giemsa stained slides following culturing in enriched NNN medium. Leishmania amastigotes were seen in the slides prepared from the footpads of the all experimental animals and all cultures were positive for promastigotes prepared from the same clinical material. But not all the experiment groups were positive for the liver, spleen and testicle preparations. According to these results it was concluded that while all rodents in the experiment groups were positive for CL, only a part of the experiment groups were positive for internal organ involvement. Accordingly, (a) All Leishmania strains caused both CL and internal organ involvement in M.unguiculatus and M.musculus, (b) only L.tropica caused CL and internal organ involvement in R.norvegicus, while other Leishmania strains only caused CL in this group, (c) in M.auratus only L.donovani caused CL while other strains caused both CL and internal organ involvement. In our study, it was determined that the rodents Meriones, Mesocricetus, Rattus and Mus genera which are part of our country’s natural habitat could serve as natural reservoirs of L.tropica, L.infantum, L.major and L.donovani, thus having the potential for the spreading of Leishmaniasis in our country and important information were gathered concerning the clinical aspects of the infection caused by Leishmania species in their potential reservoir hosts. © 2018 Ankara Microbiology Society.
