Abstract

Field captured specimens of Didelphis albiventris (Didelphimorphia: Didelphidae) from Formosa Province, Argentina, were analysed for possible infection with Babesia species. Whole blood samples of live-trapped D. albiventris were taken, genomic DNA was extracted and a Piroplasmida specific PCR assay targeting a fragment of the 18S rRNA gene was conducted. Positive PCR amplicon were sequenced and obtained DNA partial sequences were located in a phylogenetic context by constructing a maximum-likelihood tree. Two samples were positive and could be identified as Babesia species. Through phylogenetic analyses, both sequences were demonstrated to belong to a group of Babesia sp. associated with marsupials from Brazil and therefore previously defined as the “South American Marsupialia Group” (SAMG) of Babesia species. The results of this study represent the first report of a Piroplasmida species in a marsupial in Argentina. They further give an insight on the circulation of Babesia sp. in D. albiventris that, due to its synanthropic habits, plays an epidemiologically important role as potential hosts for emerging pathogens and ectoparasites of relevance in veterinary medicine.

期刊介绍： Veterinary Parasitology: Regional Studies and Reports focuses on aspects of veterinary parasitology that are of regional concern, which is especially important in this era of climate change and the rapid and often unconstrained travel of people and animals. Relative to regions, this journal will accept papers of the highest quality dealing with all aspects of disease prevention, pathology, treatment, epidemiology, and control of parasites within the field of veterinary medicine. Also, case reports will be considered as they add to information related to local disease and its control; such papers must be concise and represent appropriate medical intervention. Papers on veterinary parasitology from wildlife species are acceptable, but only if they relate to the practice of veterinary medicine. Studies on vector-borne bacterial and viral agents are suitable, but only if the paper deals with vector transmission of these organisms to domesticated animals. Studies dealing with parasite control by means of natural products, both in vivo and in vitro, are more suited for one of the many journals that now specialize in papers of this type. However, due to the regional nature of much of this research, submissions may be considered based upon a case being made by the author(s) to the Editor. Circumstances relating to animal experimentation must meet the International Guiding Principles for Biomedical Research Involving Animals as issued by the Council for International Organizations of Medical Sciences (obtainable from: Executive Secretary C.I.O.M.S., c/o W.H.O., Via Appia, CH-1211 Geneva 27, Switzerland).
