We present two cases of Leishmania (V) panamensis in returning travelers from Central America suc- cessfully treated with miltefosine. The couple presented with ulcerative skin lesions nonresponsive to antibiotics. Skin biopsy with polymerase chain reaction (PCR) revealed L. (V) panamensis. To prevent the development of mucosal disease and avoid the inconvenience of parental therapy, we treated both patients with oral miltefosine. We suggest that milte- fosine represents an important therapeutic alternative in the treatment of cutaneous lesions caused by L. panamensis and in preventing mucosal involvement. A 31-old-man and a 30-year-old woman traveled to Costa Because of the presence of a thick fibrous scar at the ul- Rica for their honeymoon. They visited many regions of this cerative lesion border, we recommended a short course of country and participated in hiking, rafting, and camping. -

Leishmaniasis in the United States: Emerging Issues in a Region of Low Endemicity
microorganisms Review Leishmaniasis in the United States: Emerging Issues in a Region of Low Endemicity John M. Curtin 1,2,* and Naomi E. Aronson 2 1 Infectious Diseases Service, Walter Reed National Military Medical Center, Bethesda, MD 20814, USA 2 Infectious Diseases Division, Uniformed Services University, Bethesda, MD 20814, USA; [email protected] * Correspondence: [email protected]; Tel.: +1-011-301-295-6400 Abstract: Leishmaniasis, a chronic and persistent intracellular protozoal infection caused by many different species within the genus Leishmania, is an unfamiliar disease to most North American providers. Clinical presentations may include asymptomatic and symptomatic visceral leishmaniasis (so-called Kala-azar), as well as cutaneous or mucosal disease. Although cutaneous leishmaniasis (caused by Leishmania mexicana in the United States) is endemic in some southwest states, other causes for concern include reactivation of imported visceral leishmaniasis remotely in time from the initial infection, and the possible long-term complications of chronic inflammation from asymptomatic infection. Climate change, the identification of competent vectors and reservoirs, a highly mobile populace, significant population groups with proven exposure history, HIV, and widespread use of immunosuppressive medications and organ transplant all create the potential for increased frequency of leishmaniasis in the U.S. Together, these factors could contribute to leishmaniasis emerging as a health threat in the U.S., including the possibility of sustained autochthonous spread of newly introduced visceral disease. We summarize recent data examining the epidemiology and major risk factors for acquisition of cutaneous and visceral leishmaniasis, with a special focus on Citation: Curtin, J.M.; Aronson, N.E. -
Leishmania Tropica
Ajaoud et al. Parasites & Vectors 2013, 6:217 http://www.parasitesandvectors.com/content/6/1/217 RESEARCH Open Access Detection and molecular typing of Leishmania tropica from Phlebotomus sergenti and lesions of cutaneous leishmaniasis in an emerging focus of Morocco Malika Ajaoud1,2, Nargys Es-sette1, Salsabil Hamdi1, Abderahmane Laamrani El-Idrissi3, Myriam Riyad2,4 and Meryem Lemrani1* Abstract Background: Cutaneous leishmaniasis is an infectious disease caused by flagellate protozoa of the genus Leishmania. In Morocco, anthroponotic cutaneous leishmaniasis due to Leishmania tropica is considered as a public health problem, but its epidemiology has not been fully elucidated. The main objective of this study was to detect Leishmania infection in the vector, Phlebotomus sergenti and in human skin samples, in the El Hanchane locality, an emerging focus of cutaneous leishmaniasis in central Morocco. Methods: A total of 643 sand flies were collected using CDC miniature light traps and identified morphologically. Leishmania species were characterized by ITS1 PCR-RFLP and ITS1-5.8S rRNA gene nested-PCR of samples from 123 females of Phlebotomus sergenti and 7 cutaneous leishmaniasis patients. Results: The sand flies collected consisted of 9 species, 7 of which belonged to the genus Phlebotomus and two to the genus Sergentomyia. Phlebotomus sergenti was the most predominant (76.67%). By ITS1 PCR-RFLP Leishmania tropica was found in three Phlebotomus sergenti females and four patients (4/7). Using nested PCR Leishmania tropica was identified in the same three Phlebotomus sergenti females and all the 7 patients. The sequencing of the nested PCR products recognized 7 haplotypes, of which 6 have never been described. -

História, Ciências, Saúde – Manguinhos, Rio de Janeiro, v.24, n.4, asymmetries out.-dez. 2017. Available at: http://www. scielo.br/hcsm. Abstract The article investigates the process of circulation of knowledge which occurred during the first decades of the twentieth century between the South American researchers Edmundo Escomel (Peru) and Alfredo Da Matta (Brazil) and the Europeans Alphonse Laveran (France) and Patrick Manson (England) with regard to the definition and validation of espundia as a disease specific to South America, while simultaneously the need to insert this illness into the newly created group of diseases called the “leishmaniasis” was proposed. Sharing recent concerns in considering historical research beyond the limits imposed by the Nation-state as a category that organizes narratives, it dialogs with some apologists of global and transnational history, situating this specific case within this analytical perspective. -

A Novel Metabarcoding Diagnostic Tool to Explore Protozoan
www.nature.com/scientificreports OPEN A novel metabarcoding diagnostic tool to explore protozoan haemoparasite diversity in Received: 20 June 2019 Accepted: 19 August 2019 mammals: a proof-of-concept study Published: xx xx xxxx using canines from the tropics Lucas G. Huggins 1, Anson V. Koehler1, Dinh Ng-Nguyen2, Stephen Wilcox3, Bettina Schunack4, Tawin Inpankaew5 & Rebecca J. Traub1 Haemoparasites are responsible for some of the most prevalent and debilitating canine illnesses across the globe, whilst also posing a signifcant zoonotic risk to humankind. Nowhere are the efects of such parasites more pronounced than in developing countries in the tropics where the abundance and diversity of ectoparasites that transmit these pathogens reaches its zenith. Here we describe the use of a novel next-generation sequencing (NGS) metabarcoding based approach to screen for a range of blood-borne apicomplexan and kinetoplastid parasites from populations of temple dogs in Bangkok, Thailand. Our methodology elucidated high rates of Hepatozoon canis and Babesia vogeli infection, whilst also being able to characterise co-infections. In addition, our approach was confrmed to be more sensitive than conventional endpoint PCR diagnostic methods. Two kinetoplastid infections were also detected, including one by Trypanosoma evansi, a pathogen that is rarely screened for in dogs and another by Parabodo caudatus, a poorly documented organism that has been previously reported inhabiting the urinary tract of a dog with haematuria. Such results demonstrate the power of NGS methodologies to unearth rare and unusual pathogens, especially in regions of the world where limited information on canine vector-borne haemoparasites exist. Protozoan haemoparasites generate some of the highest rates of morbidity and mortality in canines worldwide, whilst some are also zoonotic, capable of producing signifcant infections in humans as well1–4. -
