• Eimeria arloingi: Further studies on the development of some endogenous stages.

• Razavi SM1, Hashemnia M2, Khodakaram-Tafti A1.Author information 1Department of Pathobiology, School of Veterinary Medicine, Shiraz University, Shiraz, Iran.2Department of Pathobiology, School of Veterinary Medicine, Razi University, Kermanshah, Iran. Electronic address: m.hashemnia@razi.ac.ir.AbstractThe present study investigated the ultrastructural characteristics of gamogony and oocyst wall formation of Eimeria arloingi in experimentally infected kids. The 18 newborn animals allocated to 3 equal groups. Two of groups, A, B were inoculated with a single dose of 1×10(3) and 1×10(5) sporulated oocysts of E. arloingi, respectively. At 7, 14, 21, 28, 35, and 42days postinoculation (DPI), 1 kid from each group was necropsied for ultrastructural studies. Transmission electron microscopy was used to screen for the presence of developmental stages of the parasite. All stages of microgametocyte and macrogametocyte developments and also oocyst wall formation were observed from 7 to 42DPI. Different stages of schizigony accompanied by marked proliferation of endoplasmic reticulum, mitochondria and several granular dividing nuclei were diagnosed in the affected epithelial cells. Young microgamonts were recognizable by an electron lucent parasitophorous vacuole and several dividing nuclei with prominent nucleolar and peripheral chromatin in the cytoplasm. At a later stage, the nuclei began to elongate and a single mitochondrion and two basal bodies were observed in close proximity nucleus. These bodies eventually protruded from the surface of the gametocyte and formed two flagellar structures. Up to 80-120 microgametes were produced per microgamont. Macrogamonts were recognized by the presence of wall-forming bodies of types 1 and 2. Electron lucent WFB2 appeared earlier than the electron denser WFB1 during the process of macrogametogenesis. The outer layer of the oocyst wall was formed by the release of the contents of WFB1 at the surface to form an electron dense layer. The WFB2 appeared, subsequently, to give rise to the electron lucent inner layer. WFB1 plays a major role in oocyst wall formation.

• Isospora anthochaerae n. sp. (Apicomplexa: Eimeriidae) from a Red wattlebird (Anthochaera carunculata) (Passeriformes: Meliphagidae) in Western Australia.

• Yang R1, Brice B2, Ryan U3.Author information 1School of Veterinary and Life Sciences, Murdoch University, Murdoch, Western Australia 6150, Australia.2Kanyana Wildlife Rehabilitation Centre, 120 Gilchrist Road, Lesmurdie, Western Australia 6076, Australia.3School of Veterinary and Life Sciences, Murdoch University, Murdoch, Western Australia 6150, Australia. Electronic address: Una.Ryan@murdoch.edu.au.AbstractA new species, Isospora anthochaerae n. sp. is described from a Red wattlebird (Anthochaera carunculata). Sporulated oocysts (n=37) are subspherical, with smooth colourless to pale brown bilayered oocyst wall, 0.8μm thick (outer layer 0·6μm, inner 0.2μm thick). Oocyst with 2 spheroidal to subspheroidal sporocysts. Oocyst length, 23.4μm (20.0-26.0); oocyst width, 20.7μm (19.0-22.0); oocyst length/width (L/W) ratio, 1.1. Micropyle, oocyst residuum and polar granule are absent. Sporocysts with compact sporocyst residuum and 4 sporozoites. Sporocyst length, 14.5μm; sporocyst width, 10.1μm sporocyst L/W ratio, 1.4. Molecular analysis was conducted at four loci; the ribosomal internal transcribed spacer (ITS), the 18S and 28S ribosomal RNA and the mitochondrial cytochrome oxidase gene (COI). At the COI locus, I. anthochaerae n. sp. exhibited 98.5% similarity to Isospora lesouefi from a Regent honeyeater (Xanthomyza phrygia) and 98% similarity with an Isospora sp. (iSAT5) from a blackcap (Sylvia atricapilla). Based on morphological and molecular data, this isolate is a new species of coccidian parasite that to date has only been found in Red wattlebirds.

• Absorption and deposition of xanthophylls in broilers challenged with three dosages of Eimeria acervulina oocysts.

• Hernández-Velasco X1, Chapman HD, Owens CM, Kuttappan VA, Fuente-Martínez B, Menconi A, Latorre JD, Kallapura G, Bielke LR, Rathinam T, Hargis BM, Tellez G.Author information 1a Departamento de Medicina y Zootecnia de Aves, Facultad de Medicina Veterinaria y Zootecnia (FMVZ) , Universidad Nacional Autonóma de México (UNAM), D. F. , 04510 México City , México.AbstractAbstract 1. An experiment was designed to evaluate the effect of different doses of oocysts of Eimeria acervulina on intestinal absorption and skin deposition of xanthophylls (XAs) in broilers. 2. A total of 192 broiler chickens were randomly assigned to 4 groups: an uninfected control group and three groups inoculated with either 1 × 102, 1 × 104 or 1 × 105 sporulated oocysts of E. acervulina by gavaging at 21 d. There were 4 replicate pens (2 male and 2 female) per group. 3. Plasma xanthophyll (PX) and skin yellowness (SY) were measured in live birds weekly. At 42 d of age, SY was measured in the breast and abdomen after chilling and in the breast 24 h post-processing on refrigerated carcasses. 4. In general, in all challenged treatments, and for the duration of the study, the average PX decreased by 0.02 μg/ml (R2 = 61.6%) for every 1000 inoculated oocysts, whereas PX increased by 1.26 μg/ml/d in uninfected birds. 5. The average SY in live birds from 21 to 42 d of age decreased by 0.019 b*/every 1000 oocysts administered, while SY of uninfected controls increased by 0.57 b*/d. It was also noted that in all treatments females had a greater SY (6.17 b*) than males for the duration of the study. The SY of the breast and abdomen was correlated (r = 0.76) in chilled carcasses. Breast SY in 24 h refrigerated carcasses was greater in the control group and for female birds. 6. Oocyst excretion was different between inoculated treatments only on 7 d post-inoculation (PI). Coccidia lesion scores in the duodenum averaged 1+ in infected birds and 2+ in birds given the highest oocyst dose.
