Theileria ( الإنجليزية )

المقدمة من wikipedia EN

Theileria is a genus of parasites that belongs to the phylum Apicomplexa, and is closely related to Plasmodium. Two Theileria species, T. annulata and T. parva, are important cattle parasites.[1] T. annulata causes tropical theileriosis and T. parva causes East Coast fever. Theileria species are transmitted by ticks.[2] The genomes of T. orientalis Shintoku[3], Theileria equi WA,[4] Theileria annulata Ankara[5] and Theileria parva Muguga[6] have been sequenced and published.

Theileria equi is a known cause of equine piroplasmosis.[7]

Vaccines against Theileria are in development.[1][8] In May 2010, a vaccine that was reported to protect cattle against East Coast fever had been approved and registered by the governments of Kenya, Malawi, and Tanzania.[9]

Description

Species in this genus undergo exoerythrocytic merogony in the lymphocytes, histiocytes, erythroblasts, and other cells of the internal organs. This is followed by invasion of the erythrocytes by the merozoites, which may or may not reproduce. When merogony does occur, no more than four daughter cells are produced. The frequent occurrence of elongated bacillary or "bayonet" forms within the erythrocyte is considered as characteristic of this genus.

The organism is transmitted by various tick species, including Rhipicephalus, Dermacentor, and Haemaphysalis. The organism reproduces in the tick as it progresses through its life stages.[10] Both T. annulata and T. parva induce transformation of infected cells of lymphocyte or macrophage/monocyte lineages. T. orientalis does not induce uncontrolled proliferation of infected leukocytes and instead multiplies predominantly within infected erythrocytes.

Genomics

The genomes of T. orientalis Shintoku[3], Theileria equi WA,[4] Theileria annulata Ankara[5] and Theileria parva Muguga[6] have been sequenced. Genomic data can be accessed PiroplasmaDB which is part of the Eukaryotic Pathogen Bioinformatic Resource (EuPathDB).[11]

Evolution

The genus is thought to have first appeared in ruminants during the Miocene. It is named for Gertrud Theiler, daughter of Arnold Theiler.

Transmission

Theileria spp. can be transmitted to cattle through tick bites, including the brown ear tick, a Rhipicephalus sp.

Important species

Treatment

  • Buparvaquone is a promising compound for the therapy and prophylaxis of all forms of theileriosis.

Theileria ( الفرنسية )

المقدمة من wikipedia FR

Theileria est un genre de parasites du phylum des Apicomplexa proche de Plasmodium. Deux espèces de Theileria, T. annulata et T. parva, sont d'importants parasites du bétail (bovins, ovins, caprins)[2]. T. annulata est responsable de la theilériose tropicale et T. parva de la theilériose bovine, également appelée fièvre de la côte orientale. Theileria equi est une cause connue de piroplasmose équine[3]. Le seul parasite du genre ayant un intérêt médical semble être T. microti, responsable de la theilériose humaine. Theileria est transmis par les tiques[4].

Des vaccins contre Theileria sont en cours de développement[5]. En mai 2010, il a été rapporté qu'un vaccin protégeant les troupeaux contre la theilériose bovine avait été approuvé et enregistré par les gouvernements du Kenya, des Malawi et de Tanzanie[6].

Description

Les espèces de ce genre subissent une mérogonie exoérythrocytaire dans les lymphocytes, histiocytes, érythroblastes et autres cellules des organes internes. Celle-ci est suivie par l'invasion des érythrocytes par les mérozoïtes, qui vont alors ou non se reproduire.

Lorsque la mérogonie a lieu, ce ne sont plus que quatre cellules filles qui en sont issues.

L'apparition fréquente de formes bacillaires ou « en baïonnette » à l'intérieur des érythrocytes est considérée comme caractéristique de ce genre.

Les parasites sont transmis par différentes espèces de tiques dont Rhipicephalus, Dermacentor et Haemaphysalis. Ils se reproduisent dans les tiques lors de la progression de ces dernières dans ses différents stades évolutifs[7].

T. annulata et T. parva induisent une transformation des lignées de lymphocytes ou de macrophages/monocytes infectées les rapprochant de cellules cancéreuses. T. orientalis en revanche n'induit pas de prolifération incontrôlée des leucocytes infectés et se reproduit majoritairement au sein des érythrocytes infectés.

Génomique

Les génomes de T. annulata, T. parva et T. orientalis ont été séquencés et publiés[8],[9],[10].
