This investigation was carried out to evaluate the use of allergic skin tests in the diagnosis of pseudotuberculosis in sheep. For this purpose, two different allergens were prepared by two different methods. Allergens were prepared from C. pseudotuberculosis NVH 3368 strain. The study was carried out on farms with a total of 300 sheep in the province of Konya. The effects of two different allergens injected into four different sites in all three groups (infected, suspected and healthy) were examined (P < 0.05). At the end of the allergic skin test it was found that 73 (73%) of infected sheep tested positive. Sixty-one (83.5%) of these 73 were tested by SAT, 60 (82.1%) by postmortem examination and 38 (52.0%) by bacteriological examination (P < 0.05). All tests gave negative results for the healthy group. Moreover, in the infected animals, the sensitivity, specificity and predictive values from SAT, postmortem examination and bacteriological examination were investigated. The values were 100.0%, 29.0% and 75.5% for the axillary site. It was confirmed that the axilla is the best injection site in allergic tests. In conclusion, it was found the allergic skin test was a reliable method for the diagnosis of pseudotuberculosis in sheep in the field.

Transgenic Bovine Nuclear Transfer Embryos From Adult Somatic Cell Lines*, Sezen Arat, S. Jacek Rzucidlo, Steven L. Stice

Turkish Journal of Veterinary & Animal Sciences

This study was performed to examine whether adult fibroblast cells can be manipulated genetically and whether clonal lines derived from those cells can support embryonic development. A primary adult cell line was established from the ear of an aged cow. Adult cells with a plasmid containing the enhancer green fluorescence protein (EGFP) gene, and non-transfected cells were used for cloning. Green fluorescence expression was observed in 35/49 (71.4%) adult clones. The developmental rates of embryos were significantly lower for cell lines expressing EGFP (11.4%) than for non-transfected cells (20.1%, P < 0.05). However, there was no decrease in nuclear transfer (NT) developmental rates (21.5%) when donor nuclei from EGFP transfected cell lines not expressing EGFP but retaining neomycin-resistance gene expression were used as donor nuclei. The NT embryos from transfected and non-transfected cell lines had similar morphology and cell numbers. The results indicated that adult cells can complete clonal propagation including transfection and selection and can be used to produce transgenic NT embryos.

The Effects Of Methotrexate On The Development Of Neural Tube Defects In The Chick Embryo^#, H. Seda Vatansever, A. Şükrü Umur, V. Sevi̇nç İnan, Mehmet Selçuki̇

Turkish Journal of Veterinary & Animal Sciences

During chick development, one of the earliest differentiated tissues is the neural tube. After 24 h of incubation, a chick egg starts to differentiate and 30-48 h after incubation the neural plate is closed from head to tail to form the neural tube. If factors controlling the neural tube's closing are disrupted, this consequently causes neural tube closure defects during this time. In this study, the effect of methotrexate on the developing neural tube was investigated during early chick development. For this research, 40 specific pathogen free (SPF) white Leghorn type chick embryos were used. They were incubated for 30 …

Turkish Journal of Veterinary & Animal Sciences

The aim of this research was to determine the effect of a cage farm with a capacity of about 55 t on the benthic macrofauna in Kesikköprü Dam Lake. At 3 stations (the cage and 15 m and 60 m from the cage) selected for this purpose the abundance and composition of benthic macrofauna were determined for 11 months. The abundance of benthic macrofauna (individuals/m^2) between the stations was statistically significant (P < 0.05). The abundance of benthic macrofauna was higher at the cage station than at the other 2 stations, except in April and November. During the research period the lowest number of individuals (937 individuals/m^2) was found at the second station 15 m from the cage in February; and the highest number (14,091 individuals/m^2) was determined at the cage station in December. Members of the class Pelecypoda were found at all 3 stations. Dreissena, which is a member of the class Pelecypoda, was the most dominant benthic organism (54%), followed by Chrinomus (30%) and Tubifex (11%). At the cage station, while members of the class Pelecypoda were found, no members of the classes Insecta, Oligocheta or Crustacea were found. The highest number of benthic macrofauna genera (7) was found at the station 60 m from the cage in April and November. The lowest number of genera (1) was found at the cage station in July. The results of this study in Kesikköprü Dam Lake reveal that the cage culture has a localizing effect on the abundance and composition of benthic macrofauna.
