Die vorliegende Arbeit befasst sich mit der Identifizierung und phylogenetischen Charakterisierung der Erreger dieser F{\"a}lle. Dazu wurden verschiedene Marker im Leishmaniengenom sequenziert und mit bekannten Arten verglichen. Die untersuchte DNA stammte von autochthonen kutanen Leishmaniosen bei Pferden und einem Rind, die in den letzten zehn Jahren in Deutschland und der Schweiz auftraten. Aufgrund identischer Sequenzen konnten die Parasiten als L. siamensis identifiziert bzw. verifiziert werden, eine erst im Jahr 2008 neu beschriebene Art, die in Thailand humane viszerale Leishmaniose verursacht. Die phylogenetischen Analysen zeigten die {\"A}hnlichkeit von L. siamensis mit weiteren bisher nicht identifizierten St{\"a}mmen aus Martinique und Ghana, die kutane Leishmaniose bei Menschen verursachen.

Herein, the epidemiological status of CL, caused by L. tropica, in Turkey was examined using multilocus microsatellite typing (MLMT) of strains obtained from Turkish and Syrian patients. A total of 38 cryopreserved strains and 20 Giemsa-stained smears were included in the present study. MLMT was performed using 12 highly specific microsatellite markers. Delta K (ΔK) calculation and Bayesian statistics were used to determine the population structure. Three main populations (POP A, B and C) were identified and further examination revealed the presence of three subpopulations for POP B and C. Combined analysis was performed using the data of previously typed L. tropica strains and Mediterranean and Şanl{\i}urfa populations were identified. This finding suggests that the epidemiological status of L. tropica is more complicated than expected when compared to previous studies.

In this paper, we describe spatiotemporal and eco-epidemiological parameters of CL in Libya. Moreover, we explored current spatiotemporal distributions of CL cases and explored the future projection of the disease. Our study indicates the presence of higher risk of CL in the coastal regions of Libya. Future projection until 2060 showed a trend of increasing incidence of CL in the north-western part of Libya, a spread along the coastal region and a possible emergence of new endemics in the north-eastern districts of Libya.

We propose firstly an update classification of Leishmania species and their synonymies. We demonstrate a global map highlighting the geography of known endemic Leishmania species pathogenic to humans. We summarize a complete list of techniques currently in use and discuss their advantages and limitations. The available data highlights the benefits of molecular markers in terms of their sensitivity and specificity to quantify variation from the subgeneric level to species complexes, (sub) species within complexes, and individual populations and infection foci. Each DNA-based detection method is supplied with a comprehensive description of markers and primers and proposal for a classification based on the role of each target and primer in the detection, identification and quantification of leishmaniasis infection. We outline a genome-wide map of genes informative for diagnosis that have been used for Leishmania genotyping. Furthermore, we propose a classification method based on the suitability of well-studied molecular markers for typing the 21 known Leishmania species pathogenic to humans. This can be applied to newly discovered species and to hybrid strains originating from inter-species crosses.

Different Leishmania species are responsible for the distinct clinical patterns, such as cutaneous, mucocutaneous, and visceral leishmaniasis, with the latter being potentially fatal if left untreated. For this reason, it is important to perform correct species identification and differentiation. Fourier transform infrared spectroscopy (FTIR) is an analytical spectroscopic technique increasingly being used as a potential tool for identification of microorganisms for diagnostic purposes. By employing mid-infrared (MIR) spectral data, it is not only possible to assess the chemical structures but also to achieve differentiation supported by multivariate statistic analysis. This work comprises a pilot study on differentiation of Leishmania species of the Old World (L. major, L. tropica, L. infantum, and L. donovani) as well as hybrids of distinct species by using vibrational spectroscopic fingerprints. Films of intact Leishmania parasites and their deoxyribonucleic acid (DNA) were characterized comparatively with respect to their biochemical nature and MIR spectral patterns. The strains' hyperspectral datasets were multivariately examined by means of variance-based principal components analysis (PCA) and distance-based hierarchical cluster analysis (HCA). With the implementation of MIR spectral datasets we show that a phenotypic differentiation of Leishmania at species and intra-species level is feasible. Thus, FTIR spectroscopy can be further exploited for building up spectral databases of Leishmania parasites in view of high-throughput analysis of clinical specimens.}, language = {en} } @article{SukiasyanKeshishyanManukyanetal.2019, author = {Sukiasyan, Anna and Keshishyan, Ara and Manukyan, Dezdemonia and Melik-Andreasyan, Gayane and Atshemyan, Liana and Apresyan, Hripsime and Strelkova, Margarita V. and Frohme, Marcus and Cortes, Sofia and Kuhls, Katrin}, title = {Re-Emerging Foci of Visceral Leishmaniasis in Armenia - First Molecular Diagnosis of Clinical Samples}, series = {Parasitology}, journal = {Parasitology}, issn = {1469-8161}, doi = {10.1017/S0031182019000064}, url = {http://nbn-resolving.de/urn:nbn:de:kobv:526-opus4-12018}, pages = {20}, year = {2019}, abstract = {Visceral leishmaniasis (VL) was firstly reported in Armenia in 1913. Following a considerable increase of the number of cases until the mid 1950s, the diseases disappeared after 1969 and re-emerged in 1999.

This paper presents a historical overview about leishmaniasis in Armenia based on this literature as well as an epidemiological update since the re-emergence of the disease. In 1999- 2016, 116 indigenous VL cases were recorded mainly in children in 8 of the 11 districts, however VL is underreported because of lack of trained medical personal and diagnostic facilities. The aim of this work was to apply for the first time molecular diagnosis of VL in Armenia. Out of 25 VL suspected patients, 22 were positive by microscopy and PCR. Genotyping using ITS1-PCR-RFLP and sequencing identified the causative agent of VL in Armenia as Leishmania infantum.

To update the currently understudied sand fly distribution in Austria, a sand fly survey was performed and other entomological catches were screened for sand flies. Seven new trapping locations of Ph. mascittii are reported including the first record in Vienna, representing also one of the first findings of this species in a city. Morphological identification, supported by fluorescence microscopy, was confirmed by two molecular approaches, including sequencing and matrix-assisted laser desorption/ionization-time of flight mass spectrometry (MALDI-TOF MS) protein profiling. Sand fly occurrence and activity were evaluated based on surveyed locations, habitat requirements and climatic parameters. Moreover, a first comparison of European Ph. mascittii populations was made by two marker genes, cytochrome c oxidase subunit 1 (COI), and cytochrome b (cytb), as well as MALDI-TOF mass spectra. Our study provides new important records of Ph. mascittii in Austria and valuable data for prospective entomological surveys. MALDI-TOF MS protein profiling was shown to be a reliable tool for differentiation between sand fly species. Rising temperatures and globalization demand for regular entomological surveys to monitor changes in species distribution and composition.
