ABSTRACT The annual incidence of cutaneous leishmaniasis (CL) in Iran rose by 43% over a five year period, from 2002 to 2006; most of these cases were caused by Leishmania major. Two complementary standard and nested polymerase chain reactions (PCRs) were used to detect parasites within their natural vector, Phlebotomus papatasi. Twelve different sand fly species were morphologically identified. The most abundant species (31.3%) was P. papatasi. Leptomonads were found in nine (2.4%) phlebotomines. Twenty (5.3%) sand fly species were found positive for Leishmania-genus DNA using standard PCR. The infection rate of this species was 5% and 7% by microscopic and molecular methods, respectively.

    ABSTRACT: Zoonotic Cutaneous Leishmaniasis (ZCL) is an endemic health problem in many rural areas of Iran, with doubled number of incidences over the last decade. Different species of rodents serve as natural reservoir host for ZCL. The disease is considered as a major health problem in rural areas of Mirjaveh, Chabahar, and Konarak Counties of Sistan va Baluchistan Province. This study describes the identity of Leishmania species, isolated from Meriones hurrianae from Chabahar County using RAPD-PCR methodology. Rodents were entrapped by live traps baited with roasted walnut, tomato, and cucumber during spring and summer. All rodents were identified based on external features including fur color, ears characteristics, tail length, hind feet, body measurements, and internal features of teeth and cranium. Giemsa-stained impressions from rodents' ears were examined for amastigotes microscopically. The samples from infected rodents were cultured in NNN+LIT medium and then the harvested parasites at the stationary phase were subjected to DNA extraction followed by amplification with RAPD-PCR. All the 28 entrapped animals were identified as M. hurrianae. Five animals showed to harbor Leishmania parasite by microscopy. Leishmania DNA isolated from five M. hurrianae produced distinctive bands of L. major with four primers. However, the products that were amplified with primers AB1-07, 327, and 329 were stable and reproducible. This is the first report on the isolation and identification of L. major from M. hurrianae from Iran. Regarding infection rate of 17.8%, M. hurrianae seems to play the major role in the maintenance and transmission of disease to humans in this area.

    ABSTRACT: Abstract Human cutaneous leishmaniasis is one of the most challenging public health issues in many tropical and subtropical countries of the world, including Iran. More than half (54%) of the new zoonotic cutaneous leishmaniasis (ZCL) cases among the Eastern Mediterranean countries were reported from Iran in 2008. The detection of Leishmania parasites in rodents is essential to incriminate them as probable reservoir hosts of ZCL infection. As a result of the annual detection of about 200-250 clinical ZCL cases in the Jask district of southern Iran, feral rodents were trapped, identified to species level, and examined for Leishmania presence by preparing routine blood smears on microscopic slides from 2007 to 2008. Overall, 27 Tatera indica, 17 Gerbillus nanus, 29 Meriones persicus, 26 M. hurrianae, and 7 M. libycus were identified. Females of T. indica, M. hurrianae, and G. nanus appeared to be naturally infected with the protozoan parasite, L. major. This is the first report of microscopic and molecular detection of this trypanosomatid parasite infecting these three rodents reported from Hormozgan province in southeast Iran. More than three-quarters (82%) of the parasite-infected rodents came from the eastern plain of this province, but none of the other rodents were found to be smear-positive or kinetoplast DNA-positive by PCR. M. hurrianae, G. nanus, and T. indica are therefore incriminated as three potential reservoir hosts of L. major in Oriental parts of Iran.

    ABSTRACT: Background: Geographical distribution of zoonotic cutaneous leishmaniasis (ZCL) has continuously been extended in recent years in Iran. The Beiza District is one of the newly-emerged endemic foci of ZCL in southern Iran. The main aim of the present study was to detect the vector(s) of ZCL in this area. Methods: To detect the fauna and vectors of ZCL in this district, sand flies were caught using sticky papers. Seventy randomly selected female sand flies out of 730 were molecularly investigated for Leishmania infection using species-specific nested polymerase chain reaction (PCR) assay between April and October 2010. Results: A total of 2543 sand flies were caught. The fauna was identified as 10 species (five Phlebotomus spp. and five Sergentomyia spp.). Phlebotomus papatasi was the most dominant species both indoors and outdoors (37.55% and 16.35 %, respectively). L. major was detected in 5 out of 48 investigated Phlebotomus papatasi (10.41%). Sequence-based characterization was carried out to confirm the PCR findings. The positive samples were shown to have 75-88% similarity with L. major sequences in GenBank. Conclusion: According to the findings of the present study, similar to the other foci of ZCL in Iran, P. papatasi is the proven and primary vector of CL. This study could be drawn upon for future strategy planning in this newly emerged endemic focus.
