Leucocytozoon ibisi Adlard & Peirce & Lederer 2002, n. sp.
No full textLeucocytozoon ibisi n. sp. (gures 5, 6) Type host. Threskiornis molucca Cuvier (white ibis). Type locality. Currumbin, Queensland, Australia. Basis of description Macrogametocyte. A parasite with small round morphs only, not exceeding about 13 m m in diameter (table 1), exhibiting the usual staining characteristics of the genus. Nucleus slightly ovoid occupying a central to subcentral position with a small round karyosome visible; cytoplasm granular with a few hyaline vacuoles sometimes present. Host–parasite complex indicates a maximum diameter of about 15 m m; host cell nucleus occupies a peripheral position around a quarter to onethird of the parasite circumference (gure 5). Microgametocyte. Similar to the macrogametocyte but more variable in shape and slightly smaller in overall dimensions (table 1); exhibiting the usual diOEerentiating characteristics of the genus. The host cell nucleus covers slightly more of the parasite circumference (gure 6). No distinctive karyosome visible in dispersed parasite nucleus. Ratio of macrogametocyte s to microgametocyte s is 3:2. Hapantotype. IRCAH: G46312 5 from Threskiornis molucca, coll.

Leucocytozoon podargii Adlard & Peirce & Lederer 2002, n. sp.
No full textLeucocytozoon podargii n. sp. (gures 1–4) Type host. Podargus strigoides (Latham) (tawny frogmouth). Type locality. Currumbin, Queensland, Australia. Basis of description Macrogametocyte. Only round morphs occur, exhibiting the usual characteristics of the genus. Maximum diameter is about 15 m m (table 1). Cytoplasm is granular with occasional hyaline vacuoles present; nucleus generally oval in shape occupying a central to subcentral position but lacking a distinct karyosome. Maximum length of the host–parasite complex is 17 m m. The host cell nucleus forms a cap around the periphery covering about one-third (gure 1), but in most infections about half the parasites were observed without any remnant of the host cell nucleus (gure 2). Microgametocyte. Similar in size to the macrogametocyt e with the usual diOEerentiating characteristics. The nucleus is dispersed but has a distinctive karyosome which stains a deep red (gure 3). The prevalence of microgametocytes is very low with the ratio to macrogametocyte s being 1:50. Schizonts. In histopathology sections stained with H and E, the presence of schizonts was observed in skeletal muscle, lung and spleen. The schizonts in muscle were small compared to those in lung and spleen (gure 4). Megaloschizonts in lung and spleen tissue measured up to 163 m m in diameter and were characterized by cytomere formation with each section packed with merozoites. Hapantotype. IRCAH: G46311 2 (gametocytes) from Podargus strigoides, coll. Reid, 14 October 1999, Currumbin, Gold Coast, Queensland, Australia; IRCAH: G46311 3 (schizonts) from P. strigoides, coll. Lederer, 14 November 1998, Currumbin, Gold Coast, Queensland, Australia. Parahapantotype. IRCAH: G463114, G463115 and G463116 (gametoctyes) from P. strigoides, coll. Reid, 16 August 1999, 19 September 1999 and 10 October 1999; IRCAH: G46311 7 (schizonts) from P. strigoides, coll. Lederer, 14 November 1998, Currumbin, Gold Coast, Queensland, Australia. Other hosts. Probably occurs throughout the range of the Podargidae. Vectors. Unknown, but assumed to be simuliids. Etymology. Named after the genus of the type host. Comments. Leucocytozoon podargii is a parasite with only round morphs occurring in a small family of birds with a distribution restricted to the Australasian region. The inclusion of schizont stages is a bonus particularly as the presence of megaloschizonts occurs in the absence of second generation elongate morphs. In this respect L. podargii appears to have a life cycle similar to that of Leucocytozoon marchouxi Mathis and Leger (see Peirce et al., 1997). Nothing is currently known regarding the potential pathogenicity of L. podargii; the reason for euthanasia in this particular bird was related to causes other than the Leucocytozoon infection. The low prevalence of microgametocyte s in all the positive birds examined seems to be a characteristic of L. podargii infections. The earliest published record of leucocytozoids from the Podargidae was by Cleland (1915) who recognized Leucocytozoon sp. from P. strigoides from Eidsvold in southern Queensland. Later, Mackerras and Mackerras (1960) assigned leucocytozoids from the same host and locality to Leucocytozoon caprimulgi Kerandel originally described from the nightjar Caprimulgus fossii Hartlaub, a species with Afro-Tropical distribution. Their contention was that host relationships dictated conspecicity of the leucocytozoid. However, C. fossii is placed within the family Caprimulgidae (see Sibley and Monroe, 1990, 1993) while it has long been recognized that P. strigoides is a member of the Australasian-endemic bird family, Podargidae. Taking into account the established host-specicity at family level of Leucocytozoon spp. (see discussion in Bennett et al., 1991) and in the absence of any data to the contrary, we describe this species as L. podargii.Published as part of Adlard, R.

Leucocytozoon otidis Adlard & Peirce & Lederer 2002, n. sp.
No full textLeucocytozoon otidis n. sp. (gures 7, 8) Type host. Ardeotis kori Burchell (Kori bustard). Type locality. Kajiado, Kenya. Basis of description Macrogametocyte. A small parasite with round morphs only, with a diameter of about 14 m m (table 1), exhibiting the usual staining characteristics. The cytoplasm is granular with the presence of numerous small hyaline vacuoles; nucleus is central to sub-central, round to oval in shape with a distinctive dark staining karyosome (gures 7, 8). The host–parasite complex has an overall length of about 16 m m and the host cell nucleus forms a cap on the periphery of the parasite covering between a quarter and a third of the circumference (gures 7, 8). Microgametocyte. Similar to the macrogametocyt e with the usual diOEerentiating staining characteristics. The prevalence of microgametocytes is low and the ratio to macrogametocytes is 1:25. Hapantotype. IRCAH: G46310 3 from Ardeotis kori, coll. Joyner, 18 March 1967, Kajiado, Kenya. Parahapantotypes. IRCAH: G46310 4 and G463105 from Clamydotis undulata (Jacquin), coll. Silvanose, 7 June 1999, Abu Dhabi, UAE (birds imported from Pakistan). Other hosts. There are records of Leucocytozoon from several species of Otidae in the IRCAH database (Bennett et al., 1982; Bishop and Bennett, 1992), but no slides were available for study. It is assumed that all records can be referred to L. otidis. Vectors. Unknown, but assumed to be simuliids. Etymology. Named after the host family. Comments. Leucocytozoon otidis is a relatively small round morph and is considered to be a distinct species based on assumed host-specicity at the family/subfamily level (Bennett et al., 1991). The Otidae have a wide distribution throughout Europe, Africa and Asia and it is likely that L. otidis occurs throughout this range. Bustards generally inhabit dry bushland and savannah which probably accounts for the apparent low prevalence of L. otidis as the vectors would be sparse in such areas.Published as part of Adlard, R.

La communication du sens dans le contexte d'une tradution du français vers l'anglais d'un roman contemporain marocain,Une Via à Trois, par Bahaa Travelsi
No full textIncludes abstract.Includes bibliographical references.This thesis examines the communication of meaning in the context of the translation from French into English of a contemporary Moroccan novel, Une Vie à Trois, by Bahaa Trabelsi. To explore the notion of a faithful translation, the approach of the Ecole Superieure d'lnterpretes et de Traducteurs (ESIT) is examined. This approach, developed by Danica Seleskovitch and Marianne Lederer, emphasises the communication of meaning and the crucial role that interpretation plays in the act of translation. The project is composed of two parts - the practical application of the ESIT approach in the production of a translation of Une Vie à Trois and a theoretical study of the approach
