Abstract
Background: Epidemiological data related to leishmaniases or Leishmania infection in horses are scarce. However, studies carried out in different regions in the world showed equids parasitised by Leishmania braziliensis, L. infantum and L. martiniquensis.
Objectives: Identify the Leishmania species causing cutaneous leishmaniasis in a mare, living in Rio de Janeiro State (Brazil), and search the presence of Leishmania viruses in the isolated parasite.
Methods: Isoenzymes and polymerase chain reaction (PCR) targeting ITSrDNA region followed by sequencing were conducted for typing the isolated parasite. A search for Leishmania virus infection was also performed.
Findings: The mare presented skin nodules and ulcers in the left pinna caused by Leishmania spp. that was detected by culture and PCR. The parasite was identified as Leishmania (Mundinia) martiniquensis, infected by Leishbunyavirus (LBV), representing the first description of this species in South America. The animal travelled to different Brazilian regions, but not to outside the country.
Main conclusions: The worldwide distribution of L. martiniquensis and its infection by LBV were confirmed in this study, indicating the autochthonous transmission cycle in Brazil. The clinical profile of the disease in the mare, showing fast spontaneous healing of cutaneous lesions, may indicate that skin lesions related to L. martiniquensis infection in horses might be underdiagnosed.
期刊介绍：
Memórias do Instituto Oswaldo Cruz is a journal specialized in microbes & their vectors causing human infections. This means that we accept manuscripts covering multidisciplinary approaches and findings in the basic aspects of infectious diseases, e.g. basic in research in prokariotes, eukaryotes, and/or virus. Articles must clearly show what is the main question to be answered, the hypothesis raised, and the contribution given by the study.
Priority is given to manuscripts reporting novel mechanisms and general findings concerning the biology of human infectious prokariotes, eukariotes or virus. Papers reporting innovative methods for diagnostics or that advance the basic research with these infectious agents are also welcome.
It is important to mention what we do not publish: veterinary infectious agents research, taxonomic analysis and re-description of species, epidemiological studies or surveys or case reports and data re-analysis. Manuscripts that fall in these cases or that are considered of low priority by the journal editorial board, will be returned to the author(s) for submission to another journal.
