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 Jan 2003

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.
