Detection Of Ehrlichia Canis In Dogs By Ifa Test And Dot-Elisa, Jale Erdeğer, Arda Sancak, Lale Ataseven

Turkish Journal of Veterinary & Animal Sciences

Ehrlichia canis is the causative agent of canine monocytic ehrlichiosis (CME). The aim of this study was to detect E. canis antibodies in dogs by the IFA and dot-ELISA techniques. Blood sera from 239 dogs were collected as material. IFA test and dot-ELISA were performed with commercially available test kits. The IFA test was applied according to the procedure in the IFA kit. The Immunocomb test system was used in dot-ELISA. Agreement between these techniques was analysed by the kappa (K) test. The specificity and sensitivity of dot-ELISA were calculated. Positive results were observed from 162 (67.8%) and 137 (53.3%) …

The Effect Of Sodium And Potassium Nitrate On The Quality Of Turkish Pastrami (Pastırma) During Production, Yusuf Doğruer, Ahmet Güner, Ümi̇t Gürbüz, Gürkan Uçar

Turkish Journal of Veterinary & Animal Sciences

Different ratios of sodium and potassium nitrate were added to salt (control, 1, 2 and 3%) during the salting process and its effect on the chemical and microbiological quality was investigated in different stages of Turkish pastrami (pastırma) production (before and after salting, and before and after cumin paste application). According to the chemical analysis results, the moisture and salt ratio, pH and a_w values were not significantly different between the groups (P > 0.05) but the nitrate and nitrite values were significantly different according to the nitrate ratio (P < 0.05). Before the salting of samples, Staphyococcus/Micrococcus numbers were significantly different between the groups (P < 0.05). In the other stages of production, no differences were found between the groups (P > 0.05). Except for the stages before salting, no coliform-group bacteria growth …

Gonad Histology And Spawning Pattern Of The White Grouper (Epinephelus Aeneus) From İskenderun Bay (Turkey), Mahmut Ali̇ Gökçe, İbrahi̇m Cengi̇zler, A. Argun Özak

Turkish Journal of Veterinary & Animal Sciences

The gonad histology and spawning pattern of the white grouper (Epinephelus aeneus) were determined from fish sampled from commercial catches. Histological, microscopic and macroscopic techniques were used to examine the ovaries of E. aeneus. A six stage maturity scale based on morphology was proposed to classify ovarian development. The results showed that the white grouper has an asynchronous mode of ovarian development, and the histological study of oocyte development in the white grouper indicated that two types of inclusion, first lipid and then protein, are formed during vitellogenesis. Towards maturation, protein granules and lipid droplets increased in size and number …

Turkish Journal of Veterinary & Animal Sciences

The stomach contents of 122 common carp (Cyprinus carpio L., 1758) individuals collected from lakes Tatlı and Gıcı between January 2000 and December 2000 were investigated. The Geometric Index of Importance (GII) was used to determine food preferences among individuals and to assess whether these preferences were age based. It was concluded that the diet preferences of the common carp were not dependent on age and comprise a wide variety of food items present in their natural habitat. The results are presented in tables and figures.

Investigations On The Diagnosis Of Pseudotuberculosis Infections In Sheep By Allergic Skin Tests, Yahya Kuyucuoğlu Jan 2003

Investigations On The Diagnosis Of Pseudotuberculosis Infections In Sheep By Allergic Skin Tests, Yahya Kuyucuoğlu

Turkish Journal of Veterinary & Animal Sciences

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.

Turkish Journal of Veterinary & Animal Sciences

Toxocara canis is a nematode of the family Ascaridae. Following ingestion by dogs, the infective eggs hatch and larvae penetrate the gut wall and migrate into various tissues. There are two main clinical forms of T. canis infection; visceral larva migrans and ocular larva migrans. Toxocariasis is treated with antiparasitic drugs, such as diethylcarbamazine, albendazole and mebendazole. In this study, the effects of albendazole treatment on haematological and biochemical changes in healthy and T. canis infected mice were evaluated.

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.
