  • Dourine (Trypanosoma Equiperdium Infection): a Review with Special Attention to Ethiopia
    European Journal of Biological Sciences 9 (2): 93-100, 2017 ISSN 2079-2085 © IDOSI Publications, 2017 DOI: 10.5829/idosi.ejbs.2017.93.100 Dourine (Trypanosoma equiperdium Infection): a Review with Special Attention to Ethiopia Nesradin Yune, Gemechis Biratu and Getu Asefa Jimma University College of Agriculture and Veterinary Medicine, School of Veterinary Medicine, P.O. Box: 307, Jimma, Ethiopia Abstract: Dourine is a parasitic disease of breeding equids that is transmitted directly from animal to animal during coitus. The causative agent of dourine is Trypanosoma equiperdum which is protozoan parasite of family Trypanosomatidie. This organism presents in both genital secretion of male and female equids. Trypanosoma equiperdum differs from other trpanosoma in that it’s rarely detected in blood rather primary in tissue. Dourine is the only trypanosomal disease which can not be transmitted by biological vectors or which can mostly transmitted venerally. Some times the disease can also transmitted to foals by ingestion of infected colostrum or milk. Historically, dourine has been present in Europe, Asia, Africa and North America. In Ethiopia dourine is restricted to only Arsi-Bale zone of highland area. Depending on virulence of the infecting strain, the nutritional status of the horse and stress factor, the course and clinical signs of dourine are highly variable in manifestation and severity. The disease is characterized mainly by swelling of the genitalia, cutaneous plaques and neurological signs and chronic emaciation. It’s difficult to diagnosis this disease as the organism found in tissue parasitism and is also extremely difficult to find and differentiate microscopically from T. evansi.

Box. 307, Jimma, Ethiopia Abstract: Dourine is a chronic contagious disease of breeding equids that is transmitted directly from animal to animal during coitus. The causal organism is Trypanosoma equiperdum. This organism present in the genital secretions of both infected males and females. Trypanosoma equiperdum differs from other Tryanosoma in that it’s rarely detected in blood rather primary in tissue. Dourine is the only trypanosomal disease which cannot be transmitted by biological vectors or which can mostly transmitted venerally. Sometimes the disease can also transmit to foals by ingestion of infected colostrum or milk. Dourine mainly affects horses, donkeys and mules. However, donkeys and mules are more resistant than horses and may remain unapparent carriers. Horses usually die from infection without treatment, whereas the infection may occur in donkeys and mules without obvious clinical signs. Depending on virulence of the infecting strain, the nutritional status of the horse and stress factor, the course and clinical signs of dourine are highly variable in manifestation and severity. The disease is characterized mainly by swelling of the genitalia, cutaneous plaques, neurological signs and chronic emaciation. Diagnoses depend on the recognition of clinical signs and identification of the parasite. Any introductions of horses from endemic areas should be prevented to avoid entrance of the disease in area where disease not found.

  • Natural and Induced Dyskinetoplastic Trypanosomatids: How to Live Without Mitochondrial DNA
    International Journal for Parasitology 32 (2002) 1071–1084 www.parasitology-online.com Invited review Natural and induced dyskinetoplastic trypanosomatids: how to live without mitochondrial DNA Achim Schnaufera,b,1,*, Gonzalo J. Domingoa,b,1, Ken Stuarta,b aSeattle Biomedical Research Institute, 4 Nickerson Street, Suite 200, Seattle, WA 98109, USA bUniversity of Washington, Seattle, WA 98195, USA Received 12 December 2001; received in revised form 25 January 2002; accepted 25 January 2002 Abstract Salivarian trypanosomes are the causative agents of several diseases of major social and economic impact. The most infamous parasites of this group are the African subspecies of the Trypanosoma brucei group, which cause sleeping sickness in humans and nagana in cattle. In terms of geographical distribution, however, Trypanosoma equiperdum and Trypanosoma evansi have been far more successful, causing disease in livestock in Africa, Asia, and South America. In these latter forms the mitochondrial DNA network, the kinetoplast, is altered or even completely lost. These natural dyskinetoplastic forms can be mimicked in bloodstream form T. brucei by inducing the loss of kinetoplast DNA (kDNA) with intercalating dyes. Dyskinetoplastic T. brucei are incapable of completing their usual developmental cycle in the insect vector, due to their inability to perform oxidative phosphorylation. Nevertheless, they are usually as virulent for their mammalian hosts as parasites with intact kDNA, thus questioning the therapeutic value of attempts to target mitochondrial gene expression with specific drugs. Recent experiments, however, have challenged this view. This review summarises the data available on dyskinetoplasty in trypanosomes and revisits the roles the mitochondrion and its genome play during the life cycle of T.

Several proteins in the plasma membrane, acidocalcisomes, endoplasmic reticulum, and mitochondria are involved in its homeostasis and in cell signaling roles. The plasma membrane has a Ca2+ channel for its uptake and a plasma membrane-type Ca2+-ATPase (PMCA) for its efflux. A similar PMCA is also located in acidocalcisomes, acidic organelles that are the 2+ 2+ primary Ca store and that possess an inositol 1,4,5-trisphosphate receptor (IP3R) for Ca efflux. Their mitochondria possess a mitochondrial calcium uniporter complex (MCUC) for Ca2+ uptake and a Ca2+/H+ exchanger for Ca2+ release. The endoplasmic reticulum has a sarcoplasmic-endoplasmic reticulum-type Ca2+-ATPase (SERCA) for Ca2+ uptake but no Ca2+ release mechanism has been identified. Additionally, the trypanosomatid genomes contain other membrane proteins that could potentially bind calcium and await further characterization. Keywords: calcium; Trypanosoma; Leishmania; mitochondria; acidocalcisome 1. Introduction Trypanosomatids are a group of unicellular parasitic organisms. This group includes two important genera: Trypanosoma and Leishmania, with several species that cause severe diseases in humans.

  • 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.

  • Molecular Characterization and Classification of Trypanosoma Spp
    Sánchez et al. Parasites & Vectors (2015) 8:536 DOI 10.1186/s13071-015-1129-2 RESEARCH Open Access Molecular characterization and classification of Trypanosoma spp. Venezuelan isolates based on microsatellite markers and kinetoplast maxicircle genes E. Sánchez1, T. Perrone1ˆ, G. Recchimuzzi2, I. Cardozo1, N. Biteau3, PM Aso2, A. Mijares1, T. Baltz3, D. Berthier4, L. Balzano-Nogueira5 and MI Gonzatti2* Abstract Background: Livestock trypanosomoses, caused by three species of the Trypanozoon subgenus, Trypanosoma brucei brucei, T. evansi and T. equiperdum is widely distributed throughout the world and constitutes an important limitation for the production of animal protein. T. evansi and T. equiperdum are morphologically indistinguishable parasites that evolved from a common ancestor but acquired important biological differences, including host range, mode of transmission, distribution, clinical symptoms and pathogenicity. At a molecular level, T. evansi is characterized by the complete loss of the maxicircles of the kinetoplastic DNA, while T. equiperdum has retained maxicircle fragments similar to those present in T. brucei. T. evansi causes the disease known as Surra, Derrengadera or "mal de cadeiras", while T. equiperdum is the etiological agent of dourine or "mal du coit", characterized by venereal transmission and white patches in the genitalia. Methods: Nine Venezuelan Trypanosoma spp. isolates, from horse, donkey or capybara were genotyped and classified using microsatellite analyses and maxicircle genes. The variables from the microsatellite data and the Procyclin PE repeats matrices were combined using the Hill-Smith method and compared to a group of T. evansi, T. equiperdum and T. brucei reference strains from South America, Asia and Africa using Coinertia analysis.
