The Characterization of Protein Profiles of the Isolated Aeromonas Sobria Strains From Animal Faeces by Sds-Page
(indian veterinary Journal, 2004) Boynukara, B; Korkoca, H; Senler, NG; Gulhan, T; Atalan, E
Aeromonas spp. are members of the Vibrionaceae (Janda, 1991). Although they are common in fresh surface water, their presence in faeces of several animals and humans has been proved (Boynukara et al., 2002; Jindal et al., 1993). Sodium dodecyl sulphate-polyacrylamide gel electrophoresis (SDS-PAGE) of whole-cell proteins have been used for typing several bacterial species, including Aeromonads (Stephenson and Tabaqchali 1986; Stephenson et al., 1987). A more sensible approach might be to identify isolates as A. hydrophila, A. sobria or A. caviae, and use an electrophoretic fingerprinting technique to further characterize them (Popoff, 1984), Maclnnes et al. (1979) did the first DNA hybridization experiments with Aeromonas, and concluded that the genus consist of two main evolutionary lines; a diverse group of motile Aeromonads and genetically more homogeneous non-motile Aeromonads. Fanning et al. (1985) confirmed that all strains of Aeromonas were more closely related to each other than to species in other families, and found that motile Aeromonas species could be divided into at least 10 different DNA hybridization. In this study, we aimed to characterize the Aeromonas sobria isolated from Turkish Van cat, chicken, gull and Rainbow trout and identified according to Popoff (1984) using SDS-PAGE method.
Infraciliature and Other Morphological Characteristics of Enchelyodon Longikineta N. Sp (Ciliophora, Haptoria)
(Urban & Fischer verlag, 2003) Senler, NG; Yildiz, I
in this study, the morphology of a new ciliate belonging to the genus Enchelyodon was investigated. The body is flask-shaped or broadly oval, with a rounded posterior end, a knob-like protrusion of the anterior end of the body, and a size in vivo of 160-195 x 90-130 mum. The somatic ciliature consists of about 89 longitudinal kineties made of monokinetids, three of which have short paired cilia, forming a dorsal brush which extends from the circumoral kinety nearly to the posterior end of the body. The circumoral kinety is composed of 64-96 dikinetids. The macronucleus is ribbon-shaped, long and folded. Many spherical micronuclei are scattered in the cytoplasm. There is a single posterior contractile vacuole. There are rod-shaped extrusomes of two size classes: type 1, 2.6-4.1 mum long, and type II, 51-63 mum long, measured in vivo. in addition, (developing ?) extrusomes with a globular thickening in the middle are evident in silver-impregnated samples. This combination of features is not found in any of the previously described species, and thus the Turkish population is classified as a new species Enchelyodon longikineta n. sp. It differs from its nearest relatives E. armatus, E. elegans, E. longinucleatus, E. nodosus and E. trilineatus in one or more of the following features: the shape and size of the body, nuclear pattern, extrusomes, dorsal brush, contractility, number of somatic kineties.
Morphology and Morphogenesis of Fucheria Nodosa Foissner, 1983 a Little Known Haptorid Ciliate (Protozoa: Ciliophora: Haptoria)
(Assoc Advancement Zoology, 2002) Senler, NG; Yildiz, I
The morphology and morphogenesis of the haptorid ciliate Fuscheria nodosa Foissner(5), collected from the water-sediment interface of the artificial pond (Van, Turkey), have been described. Its morphology, infraciliature and silverline system were studied from living and silver-impregnated specimens. Biometrical characterizations of the living and fixed cells were also made, and our data compared with results obtained from previous works. Morphogenetic processes during division in Fuscheria nodosa are described after impregnation method. The pattern of its morphogenetic events resembles the other haptorid populations described previously. Morphogenesis commences with a proliferation of kinetosomes in kineties bearing dorsal brush.
